Re: Compiling and using FreeTDS on Mac OS X

Hi,

I'm using Panther and gcc3.3:

gcc version 3.3 20030304 (Apple Computer, Inc. build 1495)

I downloaded the nightly freetds-0.62.dev.20031118.

As Mark Lilback mentioned a few days ago, the problem with the build on 
OS X seems to be libtds_objects.a being linked in twice in a few 
places, causing a bunch of multiple symbol definition errors.

Removing libtds_objects.la in the following lines seems to fix the 
build, don't know if it's the right way of doing it though, or if it 
breaks other platforms:

src/tds/Makefile.am:
> libtds_la_LIBADD        = libtds_objects.la $(NETWORK_LIBS) 
> $(LIBICONV) ../replacements/libreplacements.la

src/ctlib/Makefile.am:
> libct_la_LIBADD =       ../tds/libtds_objects.la $(NETWORK_LIBS) 
> $(LIBICONV) ../replacements/libreplacements.la

src/dblib/Makefile.am:
> libsybdb_la_LIBADD=     ../tds/libtds_objects.la $(NETWORK_LIBS) 
> $(LIBICONV) ../replacements/libreplacements.la

src/odbc/Makefile.am:
> libtdsodbc_la_LIBADD=   ../tds/libtds_objects.la $(ODBCLIB) 
> $(NETWORK_LIBS) $(LIBICONV) ../replacements/libreplacements.la

src/server/Makefile.am:
> libtdssrv_la_LIBADD =   ../tds/libtds_objects.la $(NETWORK_LIBS) 
> $(LIBICONV) ../replacements/libreplacements.la


So then I had to add ../tds/libtds_objects.la in these lines (and I 
suppose all other library users will also have to do the same):

src/apps/Makefile.am:
> tsql_LDADD      = ../tds/libtds_objects.la $(READLINE_LIBS) $(LDADD) 
> $(NETWORK_LIBS)
> freebcp_LDADD     =    ../dblib/libsybdb.la ../tds/libtds_objects.la 
> $(NETWORK_LIBS)

src/pool/Makefile.am:
> LDADD           =       ../tds/libtds.la ../tds/libtds_objects.la 
> ../server/libtdssrv.la $(NETWORK_LIBS)

Also the OS X toolchain doesn't really like -Bsymbolic, so I removed it 
from this line to build:

src/odbc/Makefile.am:
> libtdsodbc_la_LDFLAGS = -export-symbols-regex '^(SQL|ODBCINST).*' 
> -Wl,-Bsymbolic

With these hacks libtds builds fine on OS X, though I haven't tried it 
out to see if it's usable.

I'm really a newbie to freetds, so please excuse me for the lack of a 
proper patch, I'm not even sure this is the correct approach to fix the 
problem, just providing a hint.

Thanks,
Duncan
