I get this error when I ./configure vlc-2.0.8
configure: error: libavcodec versions 55 and later are not supported
yet
I already downloaded the gits for ffmpeg, lame-3.98.4, x264, yasm-1.2.0 and installed them successfully. As I googled this error, I found out the following links:
https://patches.videolan.org/patch/1141/
http://www.mail-archive.com/vlc-commits#videolan.org/msg16415.html
these links include a patch and suggest that this patch shall be substituted or added (i don't know) to the configure.ac file which exists inside the my vlc-2.0.8 folder.
As the links do not contain a step by step instruction in order to understand what commands to use and how to add the patch file, I would thank if you guide me through that.
Cheers,
What I did is to add the following patch to configure.ac file:
AC_ARG_ENABLE(avcodec,
[ --enable-avcodec libavcodec codec (default enabled)])
AS_IF([test "${enable_avcodec}" != "no"], [
- PKG_CHECK_MODULES(AVCODEC,[libavcodec >= 54.25.0 libavutil >= 51.22.0], [
- AS_IF([test "${enable_sout}" != "no"], [
- PKG_CHECK_EXISTS([libavcodec < 55],, [
- AC_MSG_ERROR([libavcodec version 55 requires --disable-sout.])
- ])
- ])
+ PKG_CHECK_MODULES(AVCODEC,[libavcodec >= 53.34.0 libavutil >= 51.22.0], [
PKG_CHECK_EXISTS([libavcodec < 56],, [
AC_MSG_ERROR([libavcodec versions 56 and later are not supported yet.])
])
next, I ran
# autoconf
now, when running does not prompt the error for not supporting newer versions of libavcodec :)
There's a compatibility problem with this version of VLC (2.0.8) and the development version of ffmpeg on which it depends.
From: https://trac.macports.org/ticket/40025:
This will "just work" when VLC is updated to 2.1 which will happen
well before ffmpeg becomes 2.0
Without manually patching (as you've done), you may have to wait for v2.1 for a clean fix.

I am including opencv with custom build parameters in my Yocto image. For that I have an opencv_4.1.0.bbappend recipe, in which I set custom options, specifically FFMPEG. The recipe goes something like this:
DEPENDS += "ffmpeg libpng"
EXTRA_OECMAKE_append += "-DWITH_FFMPEG=ON -DWITH_GTK=OFF" # and some other options
During configure I get cmake errors and can't seem to figure out, how to satisfy the header dependencies. The errors go like this (I assume this is the reason for do_configure to fail):
CheckIncludeFile.c:1:10: fatal error: /home/janos/dev/yocto/build/tmp/work/core2-64-poky-linux/opencv/4.1.0-r0/recipe-sysroot/usr/include/libpng/png.h: No such file or directory
1 | #include </home/janos/dev/yocto/build/tmp/work/core2-64-poky-linux/opencv/4.1.0-r0/recipe-sysroot/usr/include/libpng/png.h>
CheckIncludeFile.c:1:10: fatal error: sys/videoio.h: No such file or directory
1 | #include <sys/videoio.h>
Focusing on the missing png.h header first, I am tempted to depend libpng-dev, as I also would apt install it. But there is no package for it.
When I search oe-pkgdata-util list-pkg-files -p libpng, I can find the header in a libpng-dev package:
...
libpng-dev:
/usr/bin/libpng-config
/usr/bin/libpng16-config
/usr/include/libpng16/png.h
/usr/include/libpng16/pngconf.h
/usr/include/libpng16/pnglibconf.h
/usr/include/png.h
...
...
I can also find it in libpng-src and also ffmpeg-src package (oe-pkgdata-util find-path "*png.h" was my friend). But all of these -dev and -src packages I cannot depend on in DEPENDS.
How can I get my recipe to know those headers?
Target machine is raspberrypi4-64, on which the recipe is configuring and compiling well - it fails when I build for qemux86-64, which I use for testing. Namely, my test command is MACHINE="qemux86-64" bitbake opencv.
It doesn't really answer the question which I though was the question - but this is how the opencv recipe is easily configured:
PACKAGECONFIG = "python3 libav libv4l v4l"
Looking into the opencv 4.1.0 recipe (opencv_4.1.0.bb), I could see that FFMPEG gets enabled with the libav configurable option.
As a result of depending FFMEPG, I had to whitelist "commercial" licenses in my local.conf file:
LICENSE_FLAGS_WHITELIST = "commercial"
Looking into ./build/tmp/work/aarch64-poky-linux/opencv/4.1.0-r0/temp/log.do_configure shows that opencv is correctly configured without GUI, with v4l/v4l2:, FFMPEG, python3, etc.
And so python3 in the resulting image:
import cv2
print(cv2.getBuildInformation())
After an upgrade to MacOS Catalina, I find that I can no longer install packages from source in the RStudio IDE (v1.2.5001, current stable release).
Example:
> install.packages("processx", type = "source")
trying URL 'https://cran.rstudio.com/src/contrib/processx_3.4.1.tar.gz'
Content type 'application/x-gzip' length 123430 bytes (120 KB)

Warning in install.packages :

In the process I get a popup with this message:
“clang-4.0” cannot be opened because the developer cannot be verified.
It seems that RStudio is pointed at clang from XCode 11.1, rather than the clang 8 I got from CRAN https://cran.r-project.org/bin/macosx/tools/.
Straight from R (e.g. sudo -i R in my terminal) a source install works fine, so it seems to be a matter of getting RStudio to look in the right place for the clang binary.
Any ideas?
I changed my ~/.R/Makevars file to point to a newer version of clang (R recommends 8+), e.g. CC=/usr/local/opt/llvm/bin/clang. I commented out the clang4 lines and created a new set pointing to the updated clang. Worked like a charm, now able to install R packages as usual.
Note: I had previously used brew to update llvm, which installed clang9.
Hope that helps!

You should use
bitbake -c populate_sdk <image_name> to generate the SDK based on your image;
As an alternative to locating and downloading a toolchain installer,
you can build the toolchain installer one of two ways if you have a
Build Directory:
*Use bitbake meta-toolchain. This method requires you to still install
the target sysroot by installing and extracting it separately. For
information on how to install the sysroot, see the "Extracting the
Root Filesystem" section.
*Use bitbake -c populate_sdk. This method has significant
advantages over the previous method because it results in a toolchain
installer that contains the sysroot that matches your target root
filesystem.
Also, using the variable TOOLCHAIN_HOST_TASK to add more packages.
http://www.yoctoproject.org/docs/1.8/ref-manual/ref-manual.html
This variable lists packages the OpenEmbedded build system uses when
building an SDK, which contains a cross-development environment. The
packages specified by this variable are part of the toolchain set that
runs on the SDKMACHINE, and each package should usually have the
prefix "nativesdk-". When building an SDK using bitbake -c
populate_sdk , a default list of packages is set in this
variable, but you can add additional packages to the list.
e.g.
TOOLCHAIN_HOST_TASK += “nativesdk-libqt5core-dev”
Recently I am trying to build OpenCV with CUDA support, and I met problem while building the module cudaarithm.
OpenCV source: git cloned from : http://github.com/Itseez/opencv.git
OpenCV branch: master branch
OpenCV commit:
`commit 5466e321b8c8f97536002a357e5b7ff49a5d2bf9, on Tue Feb 10 12:17:11 2015 +0000`
CUDA version: CUDA 6.5
Hardware: MacBook Pro (13-inch, Mid 2010)
GPU: NVIDIA GeForce 320M 256 MB
OS Version: OS X Yosemite
Steps I used:
1. cd in OpenCVSource, then mkdir myrelease, and cd myrelease
2. cmake -DPLANTUML_JAR=/usr/local/Cellar/plantuml/8002 -D BUILD_DOCS=1 -DPYTHON2_LIBRARY=/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config/libpython2.7.dylib -DPYTHON2_INCLUDE_DIR=/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/include/python2.7 -DPYTHON3_LIBRARY=/usr/local/Cellar/python3/3.4.2_1/Frameworks/Python.framework/Versions/3.4/lib/libpython3.4m.dylib -DPYTHON3_INCLUDE_DIR=/usr/local/Cellar/python3/3.4.2_1/Frameworks/Python.framework/Versions/3.4/include/python3.4m -D CMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -Wno-dev -DNVCC_FLAGS_EXTRA="-Xcompiler -stdlib=libstdc++; -Xlinker -stdlib=libstdc++" -DOPENCV_EXTRA_CXX_FLAGS=" -stdlib=libstdc++" -DOPENCV_EXTRA_EXE_LINKER_FLAGS="-stdlib=libstdc++" ..
3. make VERBOSE=1
Expect Result: Building success without error
Actual Result: when building OpenCVSource/modules/cudaarithm/src/cuda/transpose.cu, error happend like below:
/Users/Hawk/Documents/study/DIP/OpenCV/OpenCVSource/modules/cudaarithm/src/cuda/transpose.cu(61): *error: identifier "getInputMat" is undefined*
/Users/Hawk/Documents/study/DIP/OpenCV/OpenCVSource/modules/cudaarithm/src/cuda/transpose.cu(67): *error: identifier "getOutputMat" is undefined*
/Users/Hawk/Documents/study/DIP/OpenCV/OpenCVSource/modules/cudaarithm/src/cuda/transpose.cu(92): *error: identifier "syncOutput" is undefined*
Then what action I take:
check the code and I found these undefined symboles are defined in OpenCVSource/modules/core/include/opencv2/core/private.cuda.hpp
check the code and I confrim that the "transpose.cu" file include "opencv2/core/private.cuda.hpp"
check the building log, and I the confirm the private.cuda.hpp is in the search path of header file
cp "opencv2/core/private.cuda.hpp" as another file "opencv2/core/hawk.hpp", and then edit "transpose.cu" to include this new file, and I found
the "undifined symbole error" disapeared.
Although this is a workable workaround, I would like know whether the original OpenCV source cannot be compiled.
All, I think I found the problem cause.
Before I met such problem, I've already build and install OpenCV using older code from the git repo. So that there already have header files in my /usr/local/include/opencv2, especially there is /usr/local/include/opencv2/core/private.cuda.hpp.
However, it is an older one that doesn't define the symbols reporting undefined in above question. At the same time I found during the building nvcc have -I/usr/local/include in the command line, so that it use wrong private.cuda.hpp. As you know it should use the one in OpenCVSource, not the older installed one.
I think the solution is to gracefully remove the original installed OpenCV from my computer, then build again. I am trying and I will report later.
I'm trying to use ios-cmake to generate Xcode project targeting iOS. However, it cannot find Threads. Here's a simple CMake script for demonstration:

cmake version 2.8.10.2
None of these solutions seem to work. I found the only thing that consistently worked for me was to set the variables that FindThreads.cmake sets. In other words, define the following in your toolchain file:
set(CMAKE_THREAD_LIBS_INIT "-lpthread")
set(CMAKE_HAVE_THREADS_LIBRARY 1)
set(CMAKE_USE_WIN32_THREADS_INIT 0)
set(CMAKE_USE_PTHREADS_INIT 1)
The problem is indeed due to the call to try_compile failing in FindThreads.cmake. But for me setting CMAKE_CXX_COMPILER_WORKS was not enough. Instead, I changed the type of test performed by try_compile from trying to build an executable to trying to build a static library, by putting this in the toolchain file:
set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)
[Sept 2019] Fix for XCode 11 & iOS 13
As explained here.
Need to use XCODE_ATTRIBUTE_CODE_SIGNING_ALLOWED instead of CMAKE_XCODE_ATTRIBUTE_CODE_SIGNING_REQUIRED below to make this work:
set(CMAKE_TRY_COMPILE_PLATFORM_VARIABLES "XCODE_ATTRIBUTE_CODE_SIGNING_ALLOWED")
set(XCODE_ATTRIBUTE_CODE_SIGNING_ALLOWED "NO")
find_package(Threads REQUIRED)
unset(CMAKE_TRY_COMPILE_PLATFORM_VARIABLES)
unset(XCODE_ATTRIBUTE_CODE_SIGNING_ALLOWED)
[Aug 2019]: Info from CMake's issue tracker
The issue was discussed here and explained by #alcroito. It does not use the custom ios-cmake toolchain but the new native iOS toolchain (CMake 3.14+) but the issue is the same.
Source of the issue
When using the Xcode generator, it will try to sign applications by default. When looking for Threads, CMake calls FindThreads.cmake which will call a TRY_COMPILE test that Xcode will try to sign and fail at.
Proper solution:
Disable signing for the try_compile within FindThreads (seen here):
set(CMAKE_TRY_COMPILE_PLATFORM_VARIABLES "CMAKE_XCODE_ATTRIBUTE_CODE_SIGNING_REQUIRED")
set(CMAKE_XCODE_ATTRIBUTE_CODE_SIGNING_REQUIRED "NO")
find_package(Threads REQUIRED)
unset(CMAKE_TRY_COMPILE_PLATFORM_VARIABLES)
unset(CMAKE_XCODE_ATTRIBUTE_CODE_SIGNING_REQUIRED)
Other solutions in this thread
Make the binary of that try_compile static, which won't be signed (seen here). That's not great since it should be an executable and not a static lib.
Pass proper information to be able to sign the try_compile executable (seen here). That actually would not work for me.
Skip try_compile (seen here): not quite safe since you'll skip all your compiler tests. That would not work for me either.
Hardcode Threads by overriding what FindThreads does (seen here): quite a dirty workaround.
It turns out that the iOS toolchain currently doesn't support TRY_COMPILE, which is used by CheckIncludeFiles.cmake, which is in turn used by FindThreads.cmake. The toolchain is currently set to skip TRY_COMPILE by using:
set (CMAKE_CXX_COMPILER_WORKS TRUE)
set (CMAKE_C_COMPILER_WORKS TRUE)
Reference: http://code.google.com/p/ios-cmake/issues/detail?id=1&can=1
You can fix try_compile command using next variables in toolchain:
# toolchain.cmake
set(CMAKE_MACOSX_BUNDLE YES)
set(CMAKE_OSX_SYSROOT "iphoneos")
set(CMAKE_XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "iPhone Developer")
set(MACOSX_BUNDLE_GUI_IDENTIFIER "com.example")
And minimalistic example:
# CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(Foo)
find_package(Threads REQUIRED)
add_executable(foo foo.cpp)
Generate output:
> cmake -H. -B_builds -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake -GXcode
...
-- Looking for include file pthread.h
-- Looking for include file pthread.h - found
-- Looking for pthread_create
-- Looking for pthread_create - found
-- Found Threads: TRUE
...
Complete solution
Just to mention, I also encountered the same problem in my project. I commented out the find_package(Threads REQUIRED) line and generate the Xcode proejct. The codes compiled without errors. Maybe Xcode could automatically link with posix thread library.
The solution for me was a combination of the 2 answers before me.
Comment out the 2 lines that disable try_compile
# Skip the platform compiler checks for cross compiling
set (CMAKE_CXX_COMPILER_WORKS TRUE)
set (CMAKE_C_COMPILER_WORKS TRUE)
Then add this to the top of the IOS.cmake toolchain file.
set(MACOSX_BUNDLE_GUI_IDENTIFIER com.example)
set(CMAKE_MACOSX_BUNDLE YES)
set(CMAKE_XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "iPhone Developer")
