RE: Profiling with g++

[Carlos Marcelino Casas Cuadrado]

Hello all!
I'm trying to compile a "quite huge" C++ library in SUN Solaris with the
-pg option for profiling. It compiles fine, but when I try to make the
dynamic library it says that objects in
 
/usr/lib/libp/libc.a
and
/usr/lib/libp/libm.a
 
are not defined. Those objects are very different; they go from _mcount
to _memcpy. Without the -pg option everything goes ok. Might I be
missing some library or anything like that?
 
Thanks.

If you use g++ -pg to drive the link, it should set up to search the 
necessary libraries.  As you have not given specifics of your link 
command, we may suspect you have done differently.

Hi!
The linker options are is:

-g -pg -ansi -fpermissive -Lpaths_to_search_specific_libraries -lspecific_libraries_to_use -lshocket -shared -fPIC -lc

Thanks a lot!
