Good Day
I am trying to install mono on Red Hat Enterprise Linux Server release 5
in order to run a .NET web service on it.
The machine is a x86_64 architecture
I added the Centos-5-extras repo to yum and installed the following
packages:
apr apr-util httpd libgdiplus mod_auth_mysql mod_ssl mod_mono
bytefx-data-mysql mono-core mono-data mono-data-sqlite mono-devel
mono-extras mono-locale-extras mono-nunit mono-web mono-winforms xsp
I then restarted Apache and copied /usr/lib64/xsp/test/ to the root of
my site.
The test pages works fine except for a few oddities on the test page
such as it complaining that the colours Blue and Green not being valid
colours, the handlers/monodoc.ashx, webcontrols/dbpage1.aspx and
webcontrols/dbpage2.aspx pages generates a
System.NullReferenceException: Object reference not set to an instance
of an object, webcontrols/temperature.aspx, webcontrols/validator1.aspx
and webcontrols/web_regularexpressionvalidator.aspx generates a
System.DllNotFoundException: gdiplus.dll
At first I thought that these errors might be actual problems with the
test pages themselves but then later when I tried to start our web
service I got the following error in apache's error_log:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Am I missing something or is there a misconfiguration?
Why is the mono version in the Centos-5-extras repo only 1.2.4?
