The following are pc files:




cat ../dynamicBuild/lib/pkgconfig/freetype2.pc

cat ../dynamicBuild/lib/pkgconfig/libpng16.pc
prefix=/export/qiang/buildDir/debug-build/jdcloud_vod_ffmpeg/dynamicBuild
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/libpng16

I use the command of 'pkg-config --static', which prints nothing.




Thanks
