I'm not sure what I did to cause the following, since the multiple definition error does not appear to be on a symbol that I defined myself anywhere. It's fine if I just compile and link DBSubscriberRec, but as soon as I try to link DBSubscriber with it, I get this link error. Also, this builds fine on Solaris with a different compiler. This build attempt is on a Sun running Red Hat Linux 6.2. >$ gmake g++ -O -g -w -Wpointer-arith -Wno-uninitialized -D_POSIX_THREADS -D_POSIX_THREAD_SAFE_FUNCTIONS -D_REENTRANT -DACE_HAS_AIO_CALLS -DACE_HAS_EXCEPTIONS -fPIC -I/vob/itex_tools/MAP/common/incl -I/vob/mirs_common/include -I/vob/ccp/hdr -c DBSubscriber.C g++ -O -g -w -Wpointer-arith -Wno-uninitialized -D_POSIX_THREADS -D_POSIX_THREAD_SAFE_FUNCTIONS -D_REENTRANT -DACE_HAS_AIO_CALLS -DACE_HAS_EXCEPTIONS -fPIC -I/vob/itex_tools/MAP/common/incl -I/vob/mirs_common/include -I/vob/ccp/hdr -c DBSubscriberRec.C Linking ../../lib/libMAP_DB.so ... g++ -w -Wpointer-arith -Wno-uninitialized -D_POSIX_THREADS -D_POSIX_THREAD_SAFE_FUNCTIONS -D_REENTRANT -DACE_HAS_AIO_CALLS -DACE_HAS_EXCEPTIONS -fPIC -I/vob/itex_tools/MAP/common/incl -I/vob/mirs_common/include -I/vob/ccp/hdr -shared -o ../../lib/libMAP_DB.so DBSubscriber.o DBSubscriberRec.o DBSubscriberRec.o: In function `pair<basic_string<char, string_char_traits<char>, __default_alloc_template<true, 0> > const, basic_string<char, string_char_traits<char>, __default_alloc_template<true, 0> > >::~pair(void)': /usr/include/g++-2/stl_tree.h(.bss+0x0): multiple definition of `g_physicalLinkFlag' DBSubscriber.o(.bss+0x0):/view/fkr015_linuxsim/vob/itex_tools/MAP/common/src /MAP_DB/DBSubscriber.C: first defined here collect2: ld returned 1 exit status gmake: *** [../../lib/libMAP_DB.so] Error 1 >$ g++ -v Reading specs from /usr/lib/gcc-lib/sparc-redhat-linux/egcs-2.91.66/specs gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) Thank-you for any assistance you can provide.
