Mageia forum

Hi,

I usually try to work things like this out on my own, but I am stumped with this one.

I followed the instructions at http://gambaswiki.org/wiki/install/mageia for retrieving the development packages needed to compile Gambas3 on Mageia 3.

But then instead of retrieving the Gambas package via SVN, I downloaded the compressed archive file, gambas3-3.5.2.tar.bz2, directly from SourceForge; and of course, extracted it.

./reconf-all seems to go fine.
./configure -C seems to go fine.
make fails with an `ld` error complaining about not finding two
libraries: cblas and atlas.

These two libraries are apparently part of the GNU Scientific Library

Code: Select all

A query using ldconfig shows that the libraries are indeed installed.
At least, by their names, they look like the ones needed.

Code: Select all

[root@localhost gambas3-3.5.2]# ldconfig -p |grep cblas

Why is the linker not finding those libraries? Is the make process
perhaps expecting names in the form of "libcblas.so" without the ".3"
extension? If so, would a symbolic link of that form anywhere in the
'/usr/lib' directory tree suffice?

I thank you for any help.

Nope. Seems you have the libraries themselves installed, but not the development headers.

Have a look:

Code: Select all

[doktor5000@Mageia4 ~]$ urpmf 'libcblas.so$'
libatlas-x86_64-devel:/usr/lib64/atlas/libcblas.so
libatlas-sse-devel:/usr/lib/atlas-sse/libcblas.so
libatlas-sse2-devel:/usr/lib/atlas/libcblas.so
libatlas-sse3-devel:/usr/lib/atlas-sse3/libcblas.so
[doktor5000@Mageia4 ~]$ urpmf 'libatlas.so$'
libatlas-x86_64-devel:/usr/lib64/atlas/libatlas.so
libatlas-sse-devel:/usr/lib/atlas-sse/libatlas.so
libatlas-sse2-devel:/usr/lib/atlas/libatlas.so
libatlas-sse3-devel:/usr/lib/atlas-sse3/libatlas.so

Well that did it. Installing libatlas-sse-devel, libatlas-sse2-devel, and libatlas-sse3-devel solved the problem.

And wow, as many years as I have been using a distro with the urpm? commands (like since Mandrake 8?), and I never knew urpmf existed.

Thank you, Doktor!

There's not only urpmf, but also urpmq
