[Mono-dev] CS0006: Cannot find assembly `mgnat.dll'

[Laurent GUERBY]

Hi Rafael, I set the two variables (with export x=y)
but mcs didn't output any more information. I tried
/warning:4 but nothing too.

strace mcs log part:

...
open("/home/guerby/tmp/mgnat/src/lib/mgnat.dll", O_RDONLY|O_LARGEFILE) = 7
fstat64(7, {st_mode=S_IFREG|0644, st_size=973824, ...}) = 0
mmap2(NULL, 974848, PROT_READ, MAP_PRIVATE, 7, 0) = 0x40eb0000
mprotect(0x40eb0000, 974848, PROT_READ|PROT_EXEC) = 0
close(7)                                = 0
munmap(0x40eb0000, 973824)              = 0
mmap2(NULL, 65536, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40eb0000
write(2, "error CS0006: Cannot find assemb"..., 46error CS0006: Cannot find assembly `mgnat.dll') = 46
...

PS: are you able to reproduce the problem? This should do it:

$ cd /some/where
$ wget http://guerby.org/ftp/mgnat.dll
$ cat > ada.cs << EOF
namespace ada {
}
EOF
$ mcs /debug /r:mgnat.dll /t:library /out:mgnatcs.dll ada.cs
