VAMP Plugins by Queen Mary University of London is an amazing collection of BSD licensed software. All these plugins are at the basis of the Sonic Visualizer software
A plug Sdk to build plugins is available as well.
You can build the plugins for OSX / Linux / Win32 targets.
Queen Mart University explain well here the plugin architecture and how to build for different platforms specified above.
A Java version, jVamp is available as well. A Python wrapper also.
But, how to build for the iOS platform ?
So, I tried porting the Makefile to the iOS.
First I changed the file
build/osx/Makefile.osx
in this way:
CFLAGS := -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS
CXXFLAGS := $(CFLAGS)
LDFLAGS := -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread -exported_symbols_list=vamp-plugin.list -install_name qm-vamp-plugins.a
PLUGIN_EXT := .a
include build/general/Makefile.inc
Then build
macbookproloreto:qm-vamp-plugins loreto$ make -f build/osx/Makefile.osx
cc -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS -I. -I../qm-dsp -c -o g2cstubs.o g2cstubs.c
c++ -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS -I. -I../qm-dsp -c -o plugins/AdaptiveSpectrogram.o plugins/AdaptiveSpectrogram.cpp

#error Unsupported architecture
^**
The first issue here is that there is a unsupported architecture.
So the plugins depends on the SDK I had to build that one first:
cd /Users/loreto/Projects/AUDIO/VAMP/vamp-plugin-sdk
make -f build/Makefile.osx
Different errors occurred since I had no OGG/VORBIS library and no LOGG library. So I slightly modified the Makefile.osx removing these dependencies in the HOST_LIB flags. I had to keep libsndfile anyway:
HOST_LIBS = ./libvamp-hostsdk.a -L../10.8/inst/lib -lsndfile -ldl
So I was able to build the static libraries here:
macbookproloreto:vamp-plugin-sdk loreto$ ls -l *.a
-rw-r--r-- 1 loreto staff 709840 17 Ott 23:56 libvamp-hostsdk.a
-rw-r--r-- 1 loreto staff 183720 17 Ott 23:56 libvamp-sdk.a
Of course these static libs are targeted to arch x86_64 so I need to add armv7 arch:
ARCHFLAGS = -mmacosx-version-min=$(MINVERSION) -arch x86_64 -arch armv7
Then make clean and compile again
macbookproloreto:vamp-plugin-sdk loreto$ make -f build/Makefile.osx clean
macbookproloreto:vamp-plugin-sdk loreto$ make -f build/Makefile.osx
c++ -mmacosx-version-min=10.8 -arch x86_64 -arch armv7 -O2 -Wall -I. -I../10.8/inst/include -fPIC -c -o src/vamp-sdk/PluginAdapter.o src/vamp-sdk/PluginAdapter.cpp

make: *** [src/vamp-sdk/PluginAdapter.o] Error 1
Type definitions for arm was not found! The problem here is that the right path was
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/arm/_types.h
Ok let's fix this in the Makefile.osx again:
ARCHFLAGS = -mmacosx-version-min=$(MINVERSION) -arch armv7
CFLAGS = $(ARCHFLAGS) -fPIC --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -isystem /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/
CXXFLAGS = $(ARCHFLAGS) -O2 -Wall -I. -fPIC
CPPFLAGS ="-pipe -no-cpp-precomp -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/" -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk
then make the static targets:
make -f build/Makefile.osx sdkstatic
Wow it worked! I have a vamp host sdk .a for iOS! (I suppose to have let's say)
macbookproloreto:vamp-plugin-sdk loreto$ ls -l *.a
-rw-r--r-- 1 loreto staff 301176 18 Ott 00:35 libvamp-hostsdk.a
-rw-r--r-- 1 loreto staff 76024 18 Ott 00:35 libvamp-sdk.a
Ok but let's check with otool, since you never know:
macbookproloreto:vamp-plugin-sdk loreto$ otool -hv libvamp-sdk.a
Archive : libvamp-sdk.a
libvamp-sdk.a(PluginAdapter.o):
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC ARM V7 0x00 OBJECT 4 1128 SUBSECTIONS_VIA_SYMBOLS
libvamp-sdk.a(RealTime.o):

MH_MAGIC ARM V7 0x00 OBJECT 4 1060 SUBSECTIONS_VIA_SYMBOLS

libvamp-sdk.a(acsymbols.o):
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC ARM V7 0x00 OBJECT 3 500 SUBSECTIONS_VIA_SYMBOLS
Ok, that's the armv7 architecture.
Now, back to the plugins sdk again and change the
build/osx/Makefile.osx
as follows:
CFLAGS := -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS
CXXFLAGS := $(CFLAGS)
include build/general/Makefile.inc
Ok back again and make:
macbookproloreto:dsp loreto$ make -f build/osx/Makefile.osx
Boom! Another problem:
/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS -I. -c -o dsp/wavelet/Wavelet.o dsp/wavelet/Wavelet.cpp
cc -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS -I. -c -o hmm/hmm.o hmm/hmm.c
hmm/hmm.c:21:10: fatal error: 'clapack.h' file not found
#include <clapack.h> /* LAPACK for matrix inversion */
^
1 error generated.
make: *** [hmm/hmm.o] Error 1
macbookproloreto:dsp loreto$ vi build/osx/Makefile.osx
LAPACK not found.
But as for Apple Docs here, Apple introduced LAPACK in the Accelerate.frameworks since iOS4.0!
In fact clapack.h is here:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/clapack.h
So let's add this somewhere in the ../dsp/build/Makefile.osx
CFLAGS := -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS
And now let's make it again, but let me check the arch:
macbookproloreto:dsp loreto$ otool -hv libqm-dsp.a
Archive : libqm-dsp.a
libqm-dsp.a(Pitch.o):
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC ARM V7 0x00 OBJECT 4 516 SUBSECTIONS_VIA_SYMBOLS
libqm-dsp.a(Chromagram.o):
Mach header
Sound good! One level back in the plugins folder now and make
In file included from plugins/AdaptiveSpectrogram.cpp:15:
plugins/AdaptiveSpectrogram.h:22:10: fatal error: 'dsp/transforms/FFT.h' file not found
#include <dsp/transforms/FFT.h>
^
1 error generated.
Uhm ok the dsp/ misses the tranforms folder - gosh!
Another error:
clang: error: invalid argument '-install_name qm-vamp-plugins.a' only allowed with '-dynamiclib'
make: *** [qm-vamp-plugins.a] Error 1
Let's fix again the Makefile.osx:
CFLAGS := -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS
CXXFLAGS := $(CFLAGS)
LDFLAGS := -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread
Ok, now the error is architecture undefined symbol errors: to long look at the gist here
like:
"std::cerr", referenced from:
"typeinfo for std::istream", referenced from:
"std::ostream::put(char)""
std::ostream::operator<<(int)",
This reminds me to the boost C++ libraries!
So I need to get boost, compile for iOS then include it in the Makefile and it should work, isn't it ? This could take long...
So do this by now
macbookproloreto:vamp-plugin-sdk loreto$ echo $'\360\237\215\272'
After getting boost as iOS framework distribution from here and adding
-I/Users/loreto/Projects/AUDIO/LIBS/boost-ios/Dist/boost.framework/Headers/
I have the same error...uhm I suppose I'm missing the standard C++ library here!
macbookproloreto:Headers loreto$ locate libc++.dylib | grep iPhoneOS7.0
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/libc++.dylib
bingo!
So
-I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/libc++.dylib
Error again (doh) !
Tried with no success
-I/usr/lib/libstdc++.dylib
-lstdc++
Stucked on a very simple linking issue.
Again.
macbookproloreto:vamp-plugin-sdk loreto$ echo $'\360\237\215\272'
The most interesting part of the error is the first static library being compiled:
make -f build/osx/Makefile.osx
c++ -o qm-vamp-plugins.a g2cstubs.o plugins/AdaptiveSpectrogram.o plugins/BarBeatTrack.o plugins/BeatTrack.o plugins/DWT.o plugins/OnsetDetect.o plugins/ChromagramPlugin.o plugins/ConstantQSpectrogram.o plugins/KeyDetect.o plugins/MFCCPlugin.o plugins/SegmenterPlugin.o plugins/SimilarityPlugin.o plugins/TonalChangeDetect.o plugins/Transcription.o libmain.o -L../qm-dsp -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread
Undefined symbols for architecture armv7:
"std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::str() const", referenced from:
_VampPlugin::Vamp::RealTime::toString() const in libvamp-sdk.a(RealTime.o)
_VampPlugin::Vamp::RealTime::toText(bool) const in libvamp-sdk.a(RealTime.o)
"std::basic_ios<char, std::char_traits<char> >::widen(char) const", referenced from:
_VampPlugin::Vamp::PluginAdapterBase::Impl::getDescriptor() in libvamp-sdk.a(PluginAdapter.o)
Here we can see that one of the static library compiled does not contain the right architecture.
I have two static libraries here:
lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a
If I run otool on that I can see that the cpu time is ARM7 for both of them:
macbookproloreto:qm-vamp-plugins loreto$ otool -hv ../vamp-plugin-sdk/libvamp-sdk.a
Archive : ../vamp-plugin-sdk/libvamp-sdk.a
../vamp-plugin-sdk/libvamp-sdk.a(PluginAdapter.o):
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC ARM V7 0x00 OBJECT 4 1128 SUBSECTIONS_VIA_SYMBOLS
So what's the matter with Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/libc++.dylib ?
Try commenting in the code the usage of the standard libraries.
It's probably only used for debug.

Question
I can't figure out why for other architectures (i386, x86_64) the build happens without problems.
Perhaps I am missing some nuance, but I cannot understand which one.
Why do I need this - an application using this library must run on a simulator in a macbook with an M1 processor.
Environment specifications
MacOS 11.4
XCode v12.5
OpenSSL v1.1.1j
Compiler - AppleClang 12.0.5.12050022
Because i'm not an iOS developer, i didn't immediately understand the specifics of building libraries through make for this platform.
The problem was this:
-miphoneos-version-min specifies the deployment target for iOS, but since i am building library for the iOS simulator, me need to use -mios-simulator-version-min.
As a result, the configuration command should look like this:
./Configure iossimulator-xcrun threads no-shared "-fvisibility=hidden -mios-simulator-version-min=9.0 -fembed-bitcode -fPIC" no-asm no-hw no-async --prefix=/Users/macosuser/Build/OpenSSL/Install "-arch arm64" "-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.5.sdk"
If anyone can explain why the -miphoneos-version-min flag works as expected for i386 and x86_64 architectures, i would be grateful.
i'm building llvm/clang 3.7 with bitcode support (-fembed-bitcode). Some modules can't be linked due to error:
ld: -bundle and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES)

It seems that -bundle is added by CMake as i was not able to find it in CMakeLists.txt and -bitcode_bundle is added by SDK because of -fembed-bitcode.
How can i fix it? Any workaround (f.e. to switch off dylibs building since i don't need them)?
Check that you are not using Bundle loader in any of your projects:
and set match-O type to Executable instead of Bundle
Hope that helps, I had the same problem and fixed it
Set the Enable Bitcode build setting to No for your debug configuration:
If you don't see the Enable Bitcode option, make sure BaseSDK is set to either iOS, tvOS, or watchOS.

The following settings are used:
platform unix
compiler xcrun clang
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.
Otherwise, simply type `make' again to build the library,
or `make refdoc' to build the API reference (the latter needs python).

I am using guideline provided by VLC
I tried to change the xcrun path in build.sh (ImportedSources/vlc/extras/package/ios/build.sh) but it resets to original once I build the script.
Is there another way I could change this, so that c compiler works for me?
I am stuck on this for the last 9 days, please provide some guidance.
Thanks,
Albin.K.J
The first error is:
error: invalid deployment target '5.1.0' for architecture 'arm64' (requires
'7.0.0' or later)
... so I would suggest trying what it suggests: bumping the deployment target up from 5.1.0 to 7.0.0, or remove arm64 support.
May be wrong compiler path.
Check the CC points to the correct path also it is as expected in the script file.
I also have the same issue, setting CC correctly did the trick for me.
The required compilers are missing from your system. You need both a C++ compiler and a C compiler.
You can install the compilers (GCC and G++) using apt-get install gcc g++.
I've been trying to cross compile libogg for armv6, armv6 and i386 using the iOS 5.1 SDK in Mountain Lion. Libogg uses autoconf, and I've been having pretty similar issues with a few other libraries as well. I picked up a neat little cross-compiling script from here. I had to update it a bit to find the location of the SDK's.

create_outdir_lipo
Anyway, when building armv6 and armv7, configure finds the compiler's and sdk's okay , and the compiling stage goes off without a hitch. But they both fail to link. The armv7 build spits out the error.
ld: in section __TEXT,__text reloc 1: unknown relocation type 9 for architecture armv7 collect2: ld returned 1 exit status
And when I test the output binary with lipo :
$ lipo -info libogg.a
lipo: archive with no architecture specification: libogg.a (can't determine architecture for it)
What is strange is i386 seems to compile perfectly, (I've tried it in the simulator and all is okay).
Any suggestions on what I can do to try and fix this, or a least where I should start looking. Sorry for the massive code dumps, and thanks.
I was able to solve this by setting the optimization level on the compile to -O3 instead of -O4. With -O4 the files output do not seem to be recognizable to lipo (and even file reports them as data instead of Mach-O object arm).
Update: It seems quite a few people are encountering difficulty compiling Ogg Vorbis. I have made my build available. See: Precompiled Ogg Vorbis Libraries for iOS.
