[Mono-list] Symbol not found: _environ (libmono.0.0.0.dylib)

[Wei Qiao]

Hello,

 

I was wondering if someone could shed some light on this strange loading
error.

 

I'm trying to compile and run PythonNET under mono. PythonNet creates a
dynamic library named clr.so.  clr.so compiled fine with no errors.

 

otool output on clr.so:

/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version
7.0.0)

/Library/Frameworks/Mono.framework/Versions/1.2.3.1/lib/libgmodule-2.0.0
.600.3.dylib (compatibility version 601.0.0, current version 601.3.0)

(compatibility version 2.5.0, current version 2.5.1)

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version
1.0.0)

 

 

But when I try to load clr.so. I get the following error:

ImportError: dlopen(/Library/Python/2.5/site-packages/clr.so, 2): Symbol
not found: _environ

Referenced from:
/Library/Frameworks/Mono.framework/Versions/1.2.3.1/lib/libmono.0.0.0.dy
lib

Expected in: flat namespace

 

 

otool output on libmono.0.0.0.dylib:

 
/Library/Frameworks/Mono.framework/Versions/1.2.3.1/lib/libmono.0.0.0.dy

/usr/lib/libiconv.2.dylib (compatibility version 5.0.0, current version

It looks like libmono.0.0.0.dylib couldn't resolve symbol _environ. Any
ideas please?

 

Thanks,
