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
