Re: Script to help with cross compiling

ok, having another go at trying npp with sdk 8.0.61 in x64 ffmpeg static, using a hack of rdp's wonderful script. Need your thoughts though. So, put the npp/cuda sdk headers and whatnot in the right places and created some variables which_cuda="cuda_8.0.61" npp_config_libs=" --extra-cflags=-I/usr/${...

Re: how to cross compile ffmpeg with nvidia cuda_sdk and libnpp

Ah, this link https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=862522 seems to have done tests which indicate that cross-compiling ffmpeg with cuda-sdk is well nigh impossible with a variation of rdp's script under gcc 7.1.0. Oh well, giving up unless someone has done it and is willing to share info.

Re: how to cross compile ffmpeg with nvidia cuda_sdk and libnpp

OK, yah.
I use rdp's too and it cross-compiles with CUDA (but not cuda_sdk) and then with a few tweaks it also builds with nvidia's OpenCL too.

how to cross compile ffmpeg with nvidia cuda_sdk and libnpp

Newbie alert. Googled an issue but couldn't find a solution. So, I am seeking advice from someone who may already have invented this particular wheel or be able to provide pointers on where to next. Goal: To cross compile ffmpeg with nvidia cuda_sdk and libnpp under mingw64 so the final .exe runs un...

Re: building mingw toolchain with pthreads, gendef, widl

OK. Here's a thing though ... mingw builds with pthreads OK using a variation of the "old" zeranoe mingw build script, but I can't figure why out it does and the "new v4.0.0" doesn't except to suggest maybe it seems to be due to the "new" path structures ? In theory, there's no difference in the sof...

building mingw toolchain with pthreads, gendef, widl

Non-linux-aware-user alert: seeking a bit of advice. Zeranoe has a lovely new v4.0.0 mingw build script. From other places (eg deadsix27 https://github.com/DeadSix27/python_cross_compile_script/blob/master/mingw_build_scripts/mingw-build-script-posix_threads.sh) when using a variation of the prior m...

Thanks. My feeble attempt, with gcc 6.3.0 patches per deadsix27's script, is like this

Re: MingGW-w64 Build Script 3.6.7 - out of date ?

Just wondering, is 3.6.7 the latest ? It seems maybe not. Zeranoe's build readme says This build was compiled on Ubuntu 16.04.2 LTS: <https://www.ubuntu.com/> GCC 6.3.0 was used to compile this FFmpeg build: <http://gcc.gnu.org/> Whereas this http://zeranoe.com/scripts/mingw_w64_build/mingw-w64-buil...

roll your own using this method ? https://github.com/rdp/ffmpeg-windows-build-helpers ( the ffmpeg build appears to work nicely; please be aware the ffmpeg build is under suggested revision to use newer library dependency build versions per https://github.com/rdp/ffmpeg-windows-build-helpers/issues/...
