Hi,

I'm on CentOS 5.1 x86_64 again, and have build an rpm for libffi which 
installs these files:
(sources are from sources.redhat.com:/cvs/libffi )

/usr/lib64/libffi.la
/usr/lib64/libffi.so
/usr/lib64/libffi.so.4
/usr/lib64/libffi.a
/usr/lib64/libffi.so.4.0.1
/usr/include/ffi.h
/usr/include/ffitarget.h

# ldconfig -v|grep ffi
/usr/lib64
        libffi.so.4 -> libffi.so.4.0.1

The ffi .h files are found correctly by gambas make, but the errors 
above (which I had too), are due to the configure/make process not 
linking the libffi to gbx2
When I tweak the main/gbx/Makefile by adding -lffi on this line:

gbx2_LDADD = -lm    -ldl   -lffi

the compile of gbx2 succeeds!...

Which info/output do I have to sent, so you guys can fix the 
configure/make files, and I don't have to hack the Makefile manually?

CentOS 5.1
gambas 2.0 from cvs today
gcc version 4.1.2

Thanks,
Ron.
