  • Bug#267169: libSDL_image.la: wrong ordering of libs

    From Yann Dirson@1:229/2 to All on Sat Aug 21 01:30:12 2004
    From: [email protected]

    Package: libsdl-image1.2-dev
    Version: 1.2.3-5
    Severity: important

    Attempting to link a program (wesnoth) as -all-static using libtool
    fails with things like:

    /usr/lib/libtiff.a(tif_jpeg.o)(.text+0x4ab): In function `TIFFjpeg_write_tables':
    : undefined reference to `jpeg_write_tables'

    This appears to be caused by a wrong ordering of libraries in the .la file:

    $ grep dependency_libs /usr/lib/libSDL_image.la
    dependency_libs=' -lpthread -ljpeg -lpng -lz -ltiff -lSDL -lpthread'

    If I move -ljpeg after -ltiff, these symbols are correctly resolved.

    Fixing this is maybe just a matter of reordering the tests fo those
    libs in configure.in.

    FYI, the real issue is libtiff not shipping a .la file. That said, I
    don't really have an opinion on what should be done. Support for static
    linking is quite messy.

    If libtiff is built using libtool, that's right. But nothing prevents
    libtool libs to link against non-libtool ones anyway, and we can still
    make things better until libtiff gets improved :)
