This may be a frequent question, but I have not been able to find a
solution yet. I am trying to port out application to 64bit using a
sparc4u running Solaris 10. The application uses
autoconf/automake/libtool/gcc for configuration and building of targets.
With my first attempt at going 64 bit, I hit a problem since libtool
seems to configure only 32bit (at least for creating shared objects). Am
I missing something that I could do to make the leap to 64 bit?
Try CC="gcc -m64" ./configure ........

Yes.  1.5.22 will also allow
 configure CC=gcc CFLAGS=-m64

or, FWIW,
 configure CC=cc CFLAGS=-xarch=...

to function correctly.


Thanks to everyone's suggestions. It has been very insightful on how libtool works. I am now able to compile my applications for 64bit Solaris.

With the insight that I received from this exercise, I was wondering if any thought had been given to dynamicly creating the libtool shell script as part of the configuration of a package. With GCC being able to support 32bit and 64bit compilations, it would be nice if libtool would have the same or similar flexibility. I do recognize that libtool has the additional complication that it has to make decisions based on the compiler being used to compile the application.
