Hello !
I've got a problem with 32 bits on Snow Leopard. I'm unable to change paths inside an old leopard dylib, and i have architecture compilation problems when i compile the dylib and the project that uses it. (i've replaced personal information in the rest of the post)

I want to use libsigc++ (a signal library) in a project but :

- if i use my old leopard compiled dylib of libsigc++, an absolute path is wrong inside the dylib, when i run the application that uses the dylib, i get
Dyld Error Message: Library not loaded:
and the indicated path is wrong (as i see when i do otool -L dylib_file)
but if i do install_name_tool with the change flag
the path remain the same when i do otool -L dylib_file
in addition, if i do install_name_tool with the delete_rpath flag
i get install_name_tool: no LC_RPATH load command with path: ...

- if i try to compile libsigc++ on Snow Leopard, everything seems to work, and when i compile the project that uses the compiled libsigc++, i get :
ld: warning: in DYLIB_FILE, file is not of required architecture

I've tried, as i seen on a forum, to compile my dylib with
env CFLAGS=-arch i386 ./configure (with quotes, but it doesn't work here)
env CFLAGS=-arch i386 make (with quotes too)
but the result is the same...

My configuration in XCode is Mac OS 10.5 , i386 , gcc 4.0

So, does anybody have a solution to change my dylib paths or to be sure that my project and my dylib (compiled with configure and make) are really 32 bits ?

Thank u !

So finally
There are no problems with xcode in 64 bits, nor framework 10.6 nor gcc 4.2

The only problem was the compiling of my library in 32 bits,
the command i finally used is
{code}
./configure CFLAGS='-arch i686' LDFLAGS='-arch i686' CC='gcc -m32' CXX='g++ -m32' CHOST='i686-apple-darwin10.0.0' --target= i686-apple-darwin10.0.0 --build= i686-apple-darwin10.0.0 --host= i686-apple-darwin10.0.0
{code}
{code}
make CFLAGS='-arch i686' LDFLAGS='-arch i686' CC='gcc -m32' CXX='g++ -m32'
{code}

and it works well ! with my old xcode project coming from leopard, and just a thing to force in xcode : explicitely specify the i386 architecture

(all this works also with i686 architecture, the other 32 bits)
