hi

I've tried to open a library with che following codes:

void *h=dlopen(c_path.c_str(),RTLD_NOW);
the path it's correct.

the library is compiled using the following Makefile.am

AM_CPPFLAGS = -I${top_srcdir}/src -I.

lib_LTLIBRARIES = libgal.la

libgal_la_SOURCES = st_gal.cc
libgal_la_LDFLAGS = -lga -L/home/minerva/stshell/galib247/ga -avoid-
version -lstdc++

BUT when I load the library I get this error:

../../build/lib/libgal.so: undefined symbol:
_ZneI22st_list_const_iteratorEiRKT_S3_
even If I add -rdynamic in the main executables (as suggested by
many) I get the same error.
Thanks for your time, and I really appreciate any advice offered.


c++filt _ZneI22st_list_const_iteratorEiRKT_S3_


int operator!=<st_list_const_iterator>(st_list_const_iterator const&, st_list_const_iterator const&)


It appears that a global "operator !=" template is undefined.

If you have one of these templates in your headers somewhere, it may be the problem.

template <typename T>
int operator!=( const T &, const T & );
.
