[Mono-dev] Build failure on ARMv6/Raspberry Pi with Raspbian/armhf

[Fabian Pietsch]

Hi,

I'm trying to compile Mono GIT mono-3.12.0-branch on the Raspberry
Pi (ARMv6), on Raspbian/armhf (Mono 3.2.8), with monolite-111-latest
3.6.1.0 as bootstrap compiler.

I'm building like this:

mono $ ./autogen.sh --prefix=/usr/local EXTERNAL_MCS="/home/pi/build/mono/mono/mcs/class/lib/monolite/gmcs.exe"
[...]
mono $ SKIP_AOT=true make EXTERNAL_MCS="/home/pi/build/mono/mono/mcs/class/lib/monolite/gmcs.exe" V=1
[...]
make[8]: Entering directory '/home/pi/build/mono/mono/mcs/class/corlib'
/bin/sh ./../../mkinstalldirs ../../class/lib/build/
touch ../../class/lib/build//.stamp

Unhandled Exception:
System.TypeLoadException: Could not load type 'Mono.CSharp.CommandLineParser' from assembly 'basic, Version=3.12.1.0, Culture=neutral, PublicKeyToken=null'.
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not load type 'Mono.CSharp.CommandLineParser' from assembly 'basic, Version=3.12.1.0, Culture=neutral, PublicKeyToken=null'.

This can be reproduced simply by this:

mono $ cd mcs/class/corlib
mono/mcs/class/corlib $ MONO_PATH="./../../class/lib/basic:$MONO_PATH" /home/pi/build/mono/mono/runtime/mono-wrapper  ./../../class/lib/basic/basic.exe /help

Unhandled Exception:
System.TypeLoadException: Could not load type 'Mono.CSharp.CommandLineParser' from assembly 'basic, Version=3.12.1.0, Culture=neutral, PublicKeyToken=null'.
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not load type 'Mono.CSharp.CommandLineParser' from assembly 'basic, Version=3.12.1.0, Culture=neutral, PublicKeyToken=null'.


However, this is working fine:

mono/mcs/class/corlib $ ./../../class/lib/basic/basic.exe /help
Mono C# compiler, Copyright 2001-2011 Novell, Inc., Copyright 2011-2012 Xamarin, Inc
mcs [options] source-files
   --about              About the Mono C# compiler
   -addmodule:M1[,Mn]   Adds the module to the generated assembly
[...]


So the bootstrapped compiler itself can be run (on existing Mono), but the
newly built Mono or mscorlib.dll or something else is broken?


I already tried this from [1], but it did not help:

Please advise at what else I can try.
