Problem solved ! The problem is simply a incorrect name for the library libpng. I've uninstall the libraries libpng of my computer. Then the compilation of sage-5.10 from the beggining stop with the first error I gave :
ld: library not found for -lpng The problem simply comes from the fact that ld don't see the library libpng, because his name is incorrect. If we replace -lpng by -lpng12 in the line g++ -bundle -undefined dynamic_lookup -L/Applications/sage-5.10/local/lib build/temp.macosx-10.8-x86_64-2.7/src/_png.o build/temp.macosx-10.8-x86_64-2.7/src/mplutils.o build/temp.macosx-10.8-x86_64-2.7/CXX/cxx_extensions.o build/temp.macosx-10.8-x86_64-2.7/CXX/cxxsupport.o build/temp.macosx-10.8-x86_64-2.7/CXX/IndirectPythonInterface.o build/temp.macosx-10.8-x86_64-2.7/CXX/cxxextensions.o -L/Applications/sage-5.10/local/lib -lpng -lz -lstdc++ -lm -o build/lib.macosx-10.8-x86_64-2.7/matplotlib/_png.so it compiles. So to correct the problem I've simply make a alias of the library libpng in $SAGEROOT/local/lib/ with the same name but with 12 removed. If I restart the compilation (after the command export SAGE_KEEP_BUILT_SPKGS=yes), it compiles. And now all the tests pass ! I don't know how to modify the file $SAGEROOT/spkg/standard/libpng-1.2.35.p5.spkg to finaly correct the problem in futures distributions, but it might be easy for some people... -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
