x86_64-w64-mingw32 exception style, contrib errors
Posted: 11 Nov 2013 06:09
The x86_64-w64-mingw32-gcc provided with the AUR package maintained by rubenvb uses SEH exceptions, but it appears that the contrib binaries use SJLJ exceptions. I'm not able to say for sure, since I haven't yet compiled successfully, but I was seeing many errors about undefined SJLJ methods, gxx personality, etc.
After rebuilding gcc with sjlj exceptions, I'm hitting a lot of other compile/link errors:
With vlc disabled:
With vlc + live555 disabled:
+ mkv disabled:
+ taglib disabled:
+ qt + qt4 + skins2
+ projectm
+ chromaprint
... finished building.
I managed to build libvlc with mingw32 (i486-mingw32) although I had to edit a number of files as described here: https://forum.videolan.org/viewtopic.php?f=32&t=113974 . Unfortunately, I realized later that I need some windows system calls and stuff that mingw32 doesn't support.
I also tried compiling the contrib packages myself but I hit errors after the first 1-2 packages and I couldn't figure out how to disable contrib packages and move on. I'm going to try building taglib myself since I need that for the metadata methods, although I don't have any particular idea what's causing the errors above.
I used the git vlc. I'm on Arch Linux, x86_64.
