I am trying to compile the old gtk-sharp from source on linux, how do I force it to also compile Mono.Cairo and Mono.Posix? the help in configure does not state anything about those libraries, but their C# code is included in the source...?

With old gtk-sharp, I mean the GTK# wrapper for GTK2 obtained from https://download.mono-project.com/sources/gtk-sharp212/gtk-sharp-2.12.45.tar.gz

Mono is an open platform. So why is there not a framework for building custom compilers. with some helper tools for frontend, middle (IR, Optimizations) and Backend ?

Hi all! What is current status of mono? Will there be a new version? Is there a point in reporting bugs? Net6 doesn't cover my CPU arch (ARMv6), so I'm stuck with mono

Morning all. I have a web api project that I created using MonoDevelop. Super simple, one html file (index.html) which calls a single GET API method defined in a controller. When I run from MonoDevelop (just hitting Ctrl+F5), it's all working fine - I see my html page, and it can get a value from the controller. However, when I build the application and then try and use xsp4 to serve the application (from inside the bin folder), I can get to index.html, but my web api routes are just giving 404s. What am I missing?

I recently created a pull request but see some failures in the CI Pipeline. I am not able to really tell what the failures are. Can someone help me understand them.
My pull request: mono/mono#21120
Among the falures that are "required", these are what i see:
-- Linux AArch64 Coop Suspend — Build finished. 206257 tests run, 1200 skipped, 1 failed.
-- Linux i386 — Build finished. No test results found.
-- Windows x64 FullAOT — Build finished. 21065 tests run, 545 skipped, 1 failed.
-- mono-ci (Linux x64 FullAOT) Failing after 36m — Linux x64 FullAOT failed

I am trying to get to the root cause of why the failures happened, but i am not yet familiar with the logs. The errors don't seem to related to my changes, but while i am looking deeper, i just wanted to know if its an option to rerun these tests?

Linked with libmono-native-unified.a, but issue exists still

@akoeplinger Could you share some insights?

@zhuopeng-tan

Solved by adding -force_load $LIB/libmono-native-compat.a to Xcode "Build Settings"->"Other Linker Flags", 🤦

Hello,
I am trying to compile mono-boehm (6.12) for full-aot cross-compilation.
I have ran into one issue which involves generating offsets using the offsets-tool.
The offsets tool only generates header for SGEN, and when I do not supply cross-offsets file within the CLI - compilation stops with errors like so: abi.c:36:2: error: ‘MONO_ALIGN_value_gint8’ undeclared here (not in a function); did you mean ‘MONO_ALIGN_gint8’.

Is the offsets file required for boehm cross-compiler?
If it is, then how am I supposed to generate it?

I have inherited an old ASP.NET Webservices (non-WCF SOAP) application that is running on a very old mono-asp-net-server implementation on Linux. Wondering how difficult it will be migrate to the latest version of Mono or ASP.NET Core. There are only 20 or so endpoints.
