how to compile gif2png without discard libpng
Question
gif2png relies on libpng and zlib.
I want to build gif2png with certain version libpng, and want to keep track for libpng library. But libpng build failed. (discard libpng.so build successful.)
Compile libpng 1.5.19
wget https://master.dl.sourceforge.net/project/libpng/libpng15/older-releases/1.5.19/libpng-1.5.19.tar.gz
tar zxvf libpng-1.5.19.tar.gz
cd libpng-1.5.19
export CC=/angora/bin/angora-clang CXX=/angora/bin/angora-clang++
export USE_TRACK=1
/angora/tools/gen_library_abilist.sh /usr/lib/x86_64-linux-gnu/libz.so discard > /tmp/zlib_abilist.txt
export ANGORA_TAINT_RULE_LIST=/tmp/zlib_abilist.txt
./configure --prefix=`pwd`/install CFLAGS="-fPIC" CXXFLAGS="-fPIC" LDFLAGS="-fPIC"
make install -j10
build failure log
You can see functions like dfs$png_get_header_ver are missing for build binary pngtest, but function png_get_header_ver is present in current source folder.

configure libpng with --disable-shared can avoid this. Thanks @spinpx for point it out.
