Problem: GDIPlusInit

You are getting this error because the libgdiplus shared library can not be found on your system, this happens if you are building Mono yourself, or your operating system or packages are not properly configured.

You must ensure that you have also built the libgdiplus on your system, if you have, you must make sure that libgdiplus can be found by Mono.

Fixing this issue is an operating-system specific problem.

Linux

Make sure that the file libgdiplus.so exists and that the directory containing it is listed in either the /etc/ld.so.conf file or in the LD_LIBRARY_PATH environment variable:

$ echo $LD_LIBRARY_PATH
:/opt/mozilla/lib:/mono/lib:/usr/lib/mozilla-1.4b:/usr/local/lib

If the directory is not listed, you can add it like this:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my/new/directory
export LD_LIBRARY_PATH

If this still fails, it might be possible that one of the libraries that libgdiplus depends on does not exist, you can try to determine this using:

$ ldd /path/to/libgdiplus.so
        linux-gate.so.1 =>  (0xffffe000)
        libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb7e3c000)

        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0xb79a3000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0xb798b000)
        /lib/ld-linux.so.2 (0x80000000)

If one of those shows that it can not be resolved, you have found your problem.

LD_DEBUG=libs mono program.exe

Or you can try:

MONO_LOG_LEVEL="debug" MONO_LOG_MASK="dll" mono glue.exe

MacOS X

Make sure that the file libgdiplus.dylib exists and that the directory containing it is listed in the DYLD_LIBRARY_PATH environment variable.

You might want to try the otool command to find if there are any missing dependencies (otool is available in the devl package)

otool -L /full/path/to/libgdiplus.dylib

Windows

We have never heard about a problem on Windows with libgdiplus.
