Hello. Per ticket https://trac.ffmpeg.org/ticket/6731 I too am having
trouble cross-compiling ffmpeg.
This is the configure being used
./configure --arch=x86 --target-os=mingw32 --cross-prefix=/home/u/Desktop/ffmpeg-windows-build-helpers-withOpenCL-master/sandbox/cross_compilers/mingw-w64-i686/bin/i686-w64-mingw32-

And this is a part of my script in which I am adding libraries one by one
once I see what error message appears in each subsequent attempt to build (I
started with a set I saw in another post somewhere).
# 2017.10.14 - START add this for various errors per

being global any more ?

However I'm not quite sure what to do when I see the following errors in
config.log, so advice would be appreciated.

Update: for me with my specific set of libraries, I have had to apply

OpenJPEG will be solved soon by switching to pkg-config (which adds the
math library ldflag).

This one should be fixed by x265. It's them who should add a pthreads

I build FFmpeg and all the libraries I need every night. Since 08:00
BST on 12-Oct-2017 that build has not worked, the previous build on
11-Oct-2017 worked.
My configure command for building 64bit Linux that is run on an Ubuntu
16.04 system, which worked on Wednesday but not on Thursday, is:
./configure --extra-version=static_x86_64-pc-linux-gnu
--extra-cflags="--static -static" --extra-libs="-static"
--pkg-config-flags="--static" --cross-prefix= --arch=x86_64

--enable-libvorbis --enable-libopus --enable-libopenjpeg
--enable-libvpx --enable-libxvid --enable-libx264 --enable-libx265
(yes, the configure contains options, like cross-prefix and arch and
target that are not necessarily normally needed, but I build for
Linux, Windows 32 and 64 bit static binaries and macOS static binary
with the same configure command but with different variable
substitutions)
The configure.log extract is:

Etc. Which suggests to me that -lm is missing.
When I checkout 58143b15adda6391ec07f3eb19e80ed91d801edd, the parent
of 6dfcbd80ad446ff163b47f2bf432bbf706436ea8, my configure works.
When I checkout 6dfcbd80ad446ff163b47f2bf432bbf706436ea8 my configure
fails.
If I edit configure to add -lm to the mp3lame tests, which works for
that library, the next library test fails in a similar way. I think
6dfcbd80ad446ff163b47f2bf432bbf706436ea8 has done sevear damage to the
configuration of FFmpeg. I wonder if building static was considered,
or whether my configure command line is not passing the right
parameters to make a static builds.
