unrecognized option `-rpath'
Georg Maaß
runtime for shared libraries, using the -rpath /users/myproject/lib/
option I get this error message.
g++: unrecognized option `-rpath'
At runtime the application crashes at the first call of a function of
the library. I guess that the library is not loaded at runtime which
causes the crash.
Are there any special restrictions on the usage of this option, or is
this a bug in g++, or did I misunderstand something about this option?
I used g++ 2.95.3, which was built to generated static output by de-
fault. The application links everything static except this single
shared library.
Greetings, Georg

g++ ... -Wl,-rpath,/users/myproject/lib ...
NB : -rpath is specific to GNU ld

-rpath is an option of `ld', not `gcc/g++'. You need to use
`-Wl,-rpath,/users/....' to have it passed on to the linker.
Please see the info pages for gcc and ld for a complete description.
