Cross Compiling VLC for Win 64 on Arch Linux: undefined reference inflateEnd

[roxlu]

I'm following this guide https://wiki.videolan.org/Win32Compile/ to cross compile VLC from Arch Linux for Win 64. It seems that freetype (and harfbuzz) are not linking correctly with libz.

I'm using a script to compile that does:

Code: Select all

d=${PWD} bd=${d}/build es=${bd}/extern/sources # external sources eb=${bd}/extern/build # external build dir id=${d}/install # install dir host="x86_64-w64-mingw32" if [ ! -d ${es}/vlc-win ] ; then mkdir ${es}/vlc-win cd ${es}/vlc-win git clone http://git.videolan.org/git/vlc.git . fi cd ${es}/vlc-win if [ ! -d ${es}/vlc-win/contrib/win32 ] ; then mkdir -p ${es}/vlc-win/contrib/win32 fi cd ${es}/vlc-win/contrib/win32 ../bootstrap --host=${host} make fetch make

Then I run into these linker errors:

Code: Select all

I've installed mingw64:

Code: Select all

$ x86_64-w64-mingw32-gcc --version x86_64-w64-mingw32-gcc (GCC) 9.2.0

Any thoughts what might cause this ?

A similar problem. Did you solve it somehow?
