I'm Having problems installing Mono 2.0.1 on Ubuntu 8.04.1 LTS (Hardy) per the instructions at:
http://devarthur.blogspot.com/2008/10/compiling-mono-201-on-ubuntu-gutsy.html
Everything actually seems to install without any problems until I try to test the installation per the instructions at:
http://www.ibm.com/developerworks/library/l-mono/index.html#N1021B

then I get this error:

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Me too getting the same problem and trying to fix this since 2 days and haven't got any luck.
Have you guys fixed this problem??
Can anybody fix this??

I just had my kernel updated to 2.6.24-23-xen and still no love on the ** ERROR:(mini-amd64.c:192):amd64_patch: assertion failed: (amd64_is_imm32 (disp))

Following the bug reference that lordmortis quoted above, they say they have a patch for it here:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commitdiff;h=6b2514fb662158f2def03a618c5c671c95f636a8

But I couldn't tell you how to go about getting this applied into my slice. Any thoughts?

Well, since the kernel upgrade didn't solve the issue, I went an recompiled mono from the source with the following change taken from this article: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/237724

I have been suggested a work around for mono to work with the bugged kernel:

1. Download mono source
2. Edit file mini/mini-amd64.h adding #define MONO_ARCH_NOMAP32BIT at the end of the file, just before the last #endif
3. Compile mono using ./configure --prefix=/usr if you want to replace the current mono installation and make you life easier with GAC
4. If the case, add in GAC the assemblies not fund by the new mono installation (http://www.mono-project.com/Assemblies_and_the_GAC)

Note that this is a workaround for the kernel bug outlined in my previous post, not a fix for mono.

Hope it helps


I don't get that assertion error any longer and can compile and run mono programs now.

davel,

We have a 2.6.26 kernel in testing that should be available very soon. Send in a support ticket and we can update you when it's ready.
