Hi,
I´m trying to compile ffmpeg shared with mingw64 on Windows 10.
Here is the configure command:
./configure --arch=x86_64 --enable-shared --disable-static
--prefix=/e/Downloads/ffmpeg-dyn/
Everything looks ok.
Then I make:
mingw32-make.exe -j16
But I encounter this error:
LD libswresample/swresample-3.dll
LD libswscale/swscale-5.dll
dlltool -m i386:x86-64 -d libswresample/swresample-3.def -l
libswresample/swresample.lib -D swresample-3.dll
dlltool -m i386:x86-64 -d libswscale/swscale-5.def -l
libswscale/swscale.lib -D swscale-5.dll

Object does not exist: lib

Error 1
As you can see Object does not exist: lib does not mean anything. After
some investigations it looks like this is due to cmd.exe 8129 character
limitation for parameters. I tried to set a different ComSpec value,
without success. I also tried to do some changes in library.mak Using a
file containing *.o files but I encounter many errors.
It looks like this is a known issue but nothing I tried works :
https://trac.ffmpeg.org/ticket/6620
Any tips to fix it ?
