32 bit build fails #104

Open mvgalen opened 8 years ago

mvgalen commented 8 years ago

Building fails with the error below on 32-bit. This is caused by the -msse4.1 flag missing in CXX_FLAGS in xbmc/CMakeFiles/xbmc.dir/flags.make

For x86_64 this flag is implicitly enabled by gcc, but for 32bit it has to be explicitly set. After adding the flag the build succeeds.

OpenPHT: 1.6 Building on debian 32bit

Thanks for reporting, would greatly appreciate pull requests to help fix these compile issues.

We compile our linux variants inside the docker images in the https://github.com/RasPlex/Dockerfiles repo. Will run compile tests using ubuntu32 images to help spot 32-bit compile issues in the future.

I am first doing the whole build and then will have a go at it, although my experience in cmake is somewhat lacking.

I have managed to build i386 deb-files on jessie, wily and xenial using the latest docker images and https://github.com/RasPlex/OpenPHT/commit/0b36ed455bbffc19404095b568572e924d428316 (-msse is used by Kodi for gcc >= 4.9 on i386). Building on trusty i386 makes gcc crash at 97%.
