mach-o, but wrong architecture

[johnnykv]

after a few months away from playing with manos i had a few issues getting it to run today. (latest repo on OS X 10.7)
After compiling and trying to run manos -docs i get:

System.TypeInitializationException: An exception was thrown by the type initializer for Manos.AppHost ---> System.TypeInitializationException: An exception was thrown by the type initializer for Manos.Threading.Boundary ---> System.DllNotFoundException: libmanos

A bit of investegation boiled to the following two issues:
...
Mono: DllImport error loading library 'dlopen(/usr/local/lib/manos/libmanos.0.dylib, 9): no suitable image found. Did find:
/usr/local/lib/manos/libmanos.0.dylib: mach-o, but wrong architecture
...
Mono: DllImport error loading library 'dlopen(/usr/local/lib/manos/libev.4.dylib, 9): no suitable image found. Did find:
/usr/local/lib/manos/libev.4.dylib: mach-o, but wrong architecture
...

Both libmanos.0.dylib and libev.d.dylib is x86_64 (that is not a universal binary). Are these two files supposed to be 32 bit, 64 bit or universal?

Can someone else on OS X confirm this issue?

Regards,
Johnny

i was pointed to libmap.conf (which exists on bsd style system to map libraries to specific paths), perhaps this could also solve our stupid gnutls issue.

I can confirm the issue. Running mono w/ debugging on gives me the same error.

Still looking for a solution though. I'll keep you guys in the loop if I find something.

Great stuff. Or sorta ;-)
I was beginning to wonder if i had some local library issues - glad to
get that one ruled out.
I'll also dig some more into it and we'll see what comes up.

Thanks for the pointer on the .conf file, ill look into it.

Also, OS X identifies that library on my system (OSX 10.6) as x86_64:

$ lipo -info /usr/local/lib/manos/libmanos.0.dylib
Non-fat file: /usr/local/lib/manos/libmanos.0.dylib is architecture: x86_64

before configuring for manos, do the following:
export CC=gcc-4.0
export CXX=g++-4.0

That will build i386 binaries.

[gbluma]

Perfect. Thanks!

[johnnykv]

Great stuff, i think koush's hint would be suited for Installation.md :-)

After upgrading to Lion I don't have gcc-4.0 anymore. Any idea how to get it installed?

[cdeutsch]

Apparently doing this got me by the gcc issue:
CC="gcc-4.2 -arch i386"
CXX="g++-4.2 -arch i386"

But still getting this error when starting Manos:
