<DIV>Hello. </DIV>
<DIV>Being a non-programmer and linux newbie, I have been using the script at <A
title=https://github.com/rdp/ffmpeg-windows-build-helpers
href="https://github.com/rdp/ffmpeg-windows-build-helpers">https://github.com/rdp/ffmpeg-windows-build-helpers</A>
to cross-compile a static ffmpeg for windows using mingw, with a VM host having
Ububtu 15.10. One of the dependencies it builds is fontconfig which had
been successful until about mid Jan 2016.</DIV>
<DIV>Recently it started throwing build errors like this:</DIV>
<DIV> </DIV>
<DIV>Making all in fc-cache</DIV>
<DIV>make[2]: Entering directory

<DIV>make: *** [all] Error 2</DIV>
<DIV> </DIV>
<DIV>I understand the script uses cross-compiler gcc 5.3.0, if that helps.
</DIV>
<DIV>Any advice on how to “fix it” would be greatly appreciated. </DIV>

<DIV>The build script does, in part, this:</DIV>
