1. Solaris ODBC - linker flag needs to be set when building shared objects

   PostgreSQL Bugs List <pgsql-bugs@postgresql.org> — 2000-12-12T18:37:25Z

   Mike McDonough (mpm@goldwiretech.com) reports a bug with a severity of 2
   The lower the number the more severe it is.
   
   Short Description
   Solaris ODBC - linker flag needs to be set when building shared objects
   
   Long Description
   Linker flag which needs to be set when building shared objects to prevent a symbol in the executable overriding one in the shared object: '-Bsymbolic' needs to be set in Makefile.shlib. This flag is set for linux builds, but not for solaris.
   
     LDFLAGS_ODBC          := -Bsymbolic
     
   
   
   Sample Code
   Makefile.shlib:
   
   ---- CUT -------
   ifeq ($(PORTNAME), linux)
     install-shlib-dep     := install-shlib
     shlib                         := lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)
     LDFLAGS_SL            := -Bdynamic -shared -soname $(shlib)
     LDFLAGS_ODBC          := -Bsymbolic -lc -lm
     SHLIB_LINK            += -lc
     CFLAGS                        += $(CFLAGS_SL)
   endif
   
   ifeq ($(PORTNAME), solaris_i386)
     install-shlib-dep     := install-shlib
     shlib                         := lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)
     LDFLAGS_SL            := -G
   #+++rwhit, 12/12/00 added -Bsymbolic to fix SQLPrimaryKeys() - it's calls
   #                   to other SQL*() functions were being resolved by
   #                   the driver manager versions rather than the pgsql
   #                   versions
     LDFLAGS_ODBC          := -Bsymbolic
     SHLIB_LINK            += -ldl -lsocket -lresolv -lnsl -lm -lc
     CFLAGS                        += $(CFLAGS_SL)
   endif
   
   ifeq ($(PORTNAME), solaris_sparc)
     install-shlib-dep     := install-shlib
     shlib                         := lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)
     LDFLAGS_SL            := -G
   #+++rwhit, 12/12/00 added -Bsymbolic to fix SQLPrimaryKeys() - it's calls
   #                   to other SQL*() functions were being resolved by
   #                   the driver manager versions rather than the pgsql
   #                   versions
     LDFLAGS_ODBC          := -Bsymbolic
     SHLIB_LINK            += -ldl -lsocket -lresolv -lnsl -lm -lc
     CFLAGS                        += $(CFLAGS_SL)
   endif
   --- END CUT ---

   Can you explain why this flag is needed?  What call is getting resolved
   how and how should it have been resolved?  Since this flag is only
   portable to ELF systems the problem should really be fixed some other way.
