Hello.
Being a non-programmer and linux newbie, I have been using the script at https://github.com/rdp/ffmpeg-windows-build-helpers
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.
Recently it started throwing build errors like this:
Making all in fc-cache
make[2]: Entering directory

I understand the script uses cross-compiler gcc 5.3.0, if that helps.
Any advice on how to “fix it” would be greatly appreciated.
The build script does, in part, this:
build_fontconfig() {
download_and_unpack_file http://www.freedesktop.org/software/fontconfig/release/fontconfig-2.11.94.tar.gz
# download_and_unpack_file http://www.freedesktop.org/software/fontconfig/release/fontconfig-2.11.93.tar.gz
# cd fontconfig-2.11.93
cd fontconfig-2.11.94
generic_configure --disable-docs
do_make_and_make_install
cd ..
sed -i.bak 's/-L${libdir} -lfontconfig[^l]*$/-L${libdir}
-lfontconfig -lfreetype -lexpat/' "$PKG_CONFIG_PATH/fontconfig.pc"
}
generic_configure() {
local extra_configure_options="$1"

echo

junk left around and this is a 're make' and wasn't cleaned at reconfigure
time
fi
nice make $extra_make_options || exit 1
touch $touch_name || exit 1 # only touch if the build

else
echo "already did make $(basename "$cur_dir2")"
fi
}
do_make_install() {
local extra_make_install_options="$1"
local override_make_install_options="$2" # startingly, some need/use
something different than just 'make install'
if [[ -z $override_make_install_options ]]; then
local make_install_options="install

else
local
make_install_options="$override_make_install_options"
fi
local touch_name=$(get_small_touchfile_name already_ran_make_install

Thank you. |
