libjpeg-turbo for android

Question

I need libjpeg-turbo for android ndk. Did anyone managed to compile it as .a (static) lib? I have tried a few times, but it gave me a lot of errors only.

Answer 1

For anyone trying to build the official repo version, I had success using the patch attached here: libjpeg-turbo cross-compile to Android fails.

Then, depending on whether you're compiling for 32-bit or 64-bit:

export CFLAGS="-DSIZEOF_SIZE_T=4"

or

export CFLAGS="-DSIZEOF_SIZE_T=4"

And run cmake with -DWITH_SIMD=FALSE -DCMAKE_TOOLCHAIN_FILE=your_toolchain_file.

Of course, I'm aware that disabling SIMD is not ideal, but at least I managed to get a build I can start using. Hopefully, the buildsystem's NEON SIMD support will get fixed, in the future. Using ./configure also failed to build the correct SIMD for ARM.

Incidentally, I wish folks would contribute fixes to the main repo, rather than simply forking it. It's been 2 years since the last change to the repo cited in alex-cohn's answer.
