[Mono-list] Problems to get ZedGraph working, apache mod_mono, ok with xsp2

[David Temes]

I am trying to get the ZedGraph library working on linux, and it works if I use the xsp2 server but with with apache 2 and mod_mono 1.2.4 I get this exception:

***********

I suspect it has to do with the libgdiplus library but can not find a solution, here is the result of running "ldconfig -p | grep libgdiplus":

devel:/usr/lib# ldconfig -p | grep libgdiplus
        libgdiplus.so.0 (libc6) => /usr/lib/libgdiplus.so.0
        libgdiplus.so (libc6) => /usr/lib/libgdiplus.so

If I overwrite the lib under /usr/lib with the one at /opt/monoXXX/lib then running a web app with apache/mod_mono gives me the Application error "Color XXXX is not a valid color"

some system info just in case:
devel:/usr/lib# uname -a
Linux devel 2.6.16.38.xs3.2.0.531.3960 #2 SMP Sat Mar 24 22:03:09 UTC 2007 i686 GNU/Linux

apache 2.53, mono 1.2.4, mono 1.2.5

I discarded mono 1.2.5.1 becouse i always get the color not valid error, even with the xsp2 server

Any ideas or suggestions?

Thanks

David
