Here's how to find out: use nm to list the library contents and see what's
there.
[EMAIL PROTECTED] /artimi> nm /lib/w32api/libodbc32.a | grep SQLConnect
00000000 T [EMAIL PROTECTED]
00000000 I [EMAIL PROTECTED]
00000000 T [EMAIL PROTECTED]
00000000 I [EMAIL PROTECTED]
00000000 T [EMAIL PROTECTED]
00000000 I [EMAIL PROTECTED]
[EMAIL PROTECTED] /artimi>
It seems it's not matching because the symbol is decorated. There's an ld
option to deal with this:
--enable-stdcall-fixup Link _sym to [EMAIL PROTECTED] without warnings
To pass it through the g++ command line, you'll need to prefix it with
-Wl, so try it like this:
> g++ -Wl,--enable-stdcall-fixup -shared -o libTest.so testdb.o -lodbc32
cheers,
