Anybody compiled mimetic for iOS - ios

I want to create a mime / multipart parser for IMAP messages. I got few links which says mimetic can do this, but I am unable to compile it for iOS. Any help would be greatly appreciated.

It's old post. But maybe it will help somebody
How I built mimetic in my project (shell-script).

clang: error: invalid version number in '-miphoneos-version-min=.sd'
make: *** [rtmp.o] Error 1
Why? I have set XLDFLAGS="-isysroot $SDK -L$LIBSSL/lib -arch $ARCH -miphoneos-version-min=7.0 " and why invalid version number in '-miphoneos-version-min=.sd' occurs?
I had the same problem and resolved it by changing the -isysroot argument from:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk
to:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.3.sdk
Note that the latter is a symlink to the former on my system.
It appears that clang is implicitly setting -miphoneos-version-min= from the iPhoneOSXXX.sdk directory name. Using the link with the version number in it seems to fix the compilation issue.

Unknown option "i386".
See ./configure --help for available options.
Why Unknown option "i386".?
--extra-cflags=-arch i386 -mfpu=neon -miphoneos-version-min=4.3
Two things seem wrong here.
First, the config.log is showing that --extra-cflags=<args> is not getting escaped properly. Thus, FFmpeg's ./configure script is seeing --extra-cflags=-arch, i386, -mfpu=neon; i386 alone is not a valid flag for the script, so it fails.
You can compare your script to the one I maintain on github. I wonder what happens if you use variable expansions in the script, instead of variable replacement? e.g.
--extra-cflags="$EXTRA_CFLAGS -miphoneos-versi....
... try:
--extra-cflags="${EXTRA_CFLAGS} -miphoneos-versi....
Second, -mfpu=neon and -arch i386 together don't make sense. It looks like this script is going through the branch of the big if statement that contains PLATFORM="iPhoneOS", and not PLATFORM="iPhoneSimulator". That's just not going to work.
So, I'm not 100% sure of the fix, but those are some of your problems.

You are likely having an issue with the relative path. It's generally better (if not easier) to use the full path to your install root.
One thing you can try, if this is the issue, is to expand the path and try again ... for e.g.
export INSTALL_ROOT=$(cd ../libogg-built/i386; pwd)
./configure ...
...
--prefix="${INSTALL_ROOT}"
Let us know if that helps! Configure scripts can be very finicky.
Update: Nevermind, it's much more simpler in this case I just realized after hitting submit the first time:
CXX="xcrun --sdk iphonesimulator clang++ -arch $ARCH $IOSMV" \
./configure \
#--host=x86_64-apple-darwin \
--prefix=../$DESTDIR/$ARCH
;;
... you cannot have an #-to-end-of-line comment when you are continuing a command onto multiple lines. Just remove #--host=x86_64-apple-darwin \ and you should be set.

Your output directory for the libogg install should look something like this:

How to use/create the FFmpeg library [duplicate]

I'm trying to compile the ffmpeg by using the make and build files in iFrameExtractor example. firstly i tried to follow the readme file on the github, which only says to run the ./build_universal in ffmpeg folder. it did not work
i then tried to follow the info in INSTALL without success. i then tried doing the stuff in INSTALL followed by the ./build_universal which didn't work. All the *.a files that are imported to the project exists until the end of the build sequence. when the lipo commands in build_universal are run, which i guess concat the .a files for the different architectures(?). anyhow these leave the following errors:
lipo: specifed architecture type (armv6) for file (armv6/libavcodec.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavdevice.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavformat.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavutil.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libswscale.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
i can get the project to compile for simulator if i only use ./build_armv7 but if i run the universal the .a files are removed in the end. and only using doesn't work to build for iphone 4 .
After a week of trial and error, I was finally able to create the ffmpeg universal libraries and successfully compile and run iFrameExtractor for the device as well as the simulator.
To compile and run the project on your iPhone device OR simulator:
1) open Terminal
2) clone the repository: git clone git://github.com/lajos/iFrameExtractor.git
3) go to the ffmpeg folder in the project: cd iFrameExtractor/ffmpeg
4) run: ./configure
5) Edit the build scripts (build_armv6, build_armv7, build_i386) as follows:
These scripts assume you are using iOS SDK 5.0 on Xcode 4.2.
build_armv6:
#!/bin/tcsh -f

6) build the ffmpeg libraries: ./build_universal
7) open the xcode project and run it on your iPhone device or simulator
These steps work perfectly for me. I hope this will help others struggling to get the ffmpeg libraries working for iOS.
i downloaded the latest ffmpeg repository and used the following to compile only for armv6 and armv7. I couldn't get it working for i386, i receive errors that the cputype and subcputype are wrong. apparently the cputype is supposed to be x86 and subcputype should be intel.
anyhow i used the following build scripts to compile for the arm architectures:
build script:
#!/bin/sh
set -e
SCRIPT_DIR=$( (cd -P $(dirname $0) && pwd) )
DIST_DIR_BASE=${DIST_DIR_BASE:="$SCRIPT_DIR/dist"}
if [ -d ffmpeg ]

cp -R dist-$MAIN_ARCH/include/* $OUTPUT_DIR/include
then i import the .a files from BUILD-FOLDER/dist-uarch and it builds in xcode like a charm!
