Subject: [Python.NET] Compiling under mono
Message-ID: <20040620100210.797915fd.miles@lubin.us>

I know this isnt supposed to work yet, but no harm in trying,

When I make under mono, I get:

ilasm /nologo /dll /quiet /output=CLR.dll \
./src/runtime/CLRModule.il;
syntax error, got token `K_INT32', expecting INT64 K_AT K_FROMUNMANAGED K_CALLMOSTDERIVED
Error at: line (45) column (19)

***** FAILURE *****
make: *** [CLR.dll] Error 1

I don't know il at all, so I dont understand the error, but if you could help me make it compile, it would be great.

Thanks,
Miles

Hi Miles - I don't think it _can_ assemble correctly yet with the 
mono ilasm. 

The reason is that I have to do a terrible hack that involves 
compiling with the csharp compiler, then disassembling to IL to 
add some necessary marshalling modifiers that can't be indicated 
in csharp, and finally reassembling the result.

Last time I looked, the mono assembler couldn't deal with modopt(...) 
or modreq(...) in IL, which is what causes the error. So it 
probably won't compile under native mono tools until support for 
that is added to ilasm.
