g++ can't locate dylib to link at

[bowser]

Hello,
I'm using g++ over eclipse in a mac os x. I'm new to all these
technologies.
I created a dylib, and to test it I made another project that links to
it, but the compiler tells me that it can't locate it.
In my last build I used absolute path to be sure of the location, but
it still delivers an error.
The output is:

**** Build of configuration Debug for project gnawa_tester ****

make -k all
Building target: gnawa_tester
Invoking: MacOS X C++ Linker
g++ `/Volumes/Quark/c++projects/wxconf-debug` -L/Volumes/Quark/c+
+projects/gnawax/gnawa_proj/build/Debug -o "gnawa_tester" ./
SynthetGUI.o ./main.o -llibgnawa_proj
/usr/bin/ld: can't locate file for: -llibgnawa_proj
collect2: ld returned 1 exit status
make: *** [gnawa_tester] Error 1
make: Target `all' not remade because of errors.
Build complete for project gnawa_tester

Any help? I'm stuck here for one day and a half..
Thank you in advance.

This is a group for C++, not a group about how to use your compiler or
build environment. You really should ask on a Mac programing group, and
eclipse group, even a g++ group but not here.

Now I'm not an expert on any of the things you are doing but if I were
you I'd try -lgnawa_proj not -llibgnawa_proj, it will only take you two
minutes to try, who knows it might even work. If it doesn't try a Mac
programming group. I think they would be best placed to help you.

ok, thanks and sorry for the inconvenience.
By the way, I've already tried the way you suggested, and also tried
with and without the extension.

Well, no, you were right!
Even if the library build name starts with "lib", I have to remove
that prefix in order to link it.
Before I tried to build it without that prefix.
Thank you!
