Problems cross compiling on Debian 9 for target win64

[yethie]

Hello,

I ran the script on a debian 9 machine, targeting win64 and enabling non-free support. I got a fatal error while building tesseract:

checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-w64-mingw32
./configure: line 4220: syntax error near unexpected token `-mavx,'
./configure: line 4220: `AX_CHECK_COMPILE_FLAG(-mavx, avx=true, avx=false)'

I removed the support for tesseract and the build completed successfully. But the executables do not work as expected, when encoding a file with the libvpx encoder the program exits almost immediately with a segmentation fault error. Encoding the same video with libx264 works fine.

Is there anything I can do to help on this issue? Thanks!

Does it link for you if you remove the fno... Part from vpx' configure? That's recent...

No, if I remove the fno... part the compiler complains with this message:

/tmp/ccLGT9SD.s: Assembler messages:
/tmp/ccLGT9SD.s:19: Error: invalid register for .seh_savexmm
Makefile:155: recipe for target 'vpx_dsp/x86/sad4d_avx512.c.o' failed

I fixed it with with following steps:

1. Install additional dependency for building libtesseract: sudo apt install autoconf-archive

2. Add the following line "./autogen.sh" to cross_compile_ffmpeg.sh into this function:

  build_libtesseract() {
  build_libleptonica
  build_libtiff # no disable configure option for this in tesseract? odd...
  do_git_checkout https://github.com/tesseract-ocr/tesseract.git tesseract_git a2e72f258a3bd6811cae226a01802d # #315
  cd tesseract_git
  ./autogen.sh # <-------
  generic_configure_make_install
  ...

I would like to independently confirm that this is a problem on Debian 9.6 for target Win64.

@8pr previous post fixed this issue for me.

This problem is either still present or has re-emerged. Debian 10 host, same fix works.
