Re: Re: libstdc++



This is funny I read this post as I stopped to read the thread because I 
didn't understand what it was said in the thread, and because my english.
But, I saw my name ;-)

As a general rule, upstream should never provide binary tarball for his 
program, for Linux. Only a source tarball that the user will be able to 
So, of cource, no statically linked libraries.

I'm not sure this is a good idea, as an example for rpm like distributions 
(Fedora, Redhat, Mandriva, Opensuse, Centos, etc.), to put spec files in the 
source tree because distibutions don't use the same macros (and use distro 
specific macros) in the spec files.

What will make easier for the packagers to packages new release is that 
upstream accept some patches packagers used to package the current version.

When I got the last version (on svn repository, not the tarball), I succeded 
to compile it on my system.
When I tried to build a Fedora rpm on my system, I succeded.
But when I submitted my work on Fedora Build System, the built failed :-(
Because a problem with linking the kbool library (which, in my opinion, don't 
have to be in the kicad source, it was probably the source of the problem).

As I wasn't able to fix this problem, I asked for help on the Fedora 
developpers list, and someboby provided me the patch I used to build the 
current Fedora Kicad rpm

On this list, it was for Centos (Fedora EPEL (Extras Packages for Entreprise 
Linux)), and unfortunately, I got not solution :-(
I sad to not be able to offer the kicad new version for Centos users.

As a general rule, packagers test the binaries they built, not binaries built 
by someone.

For the less used/maintained Linux distributions, users have to be able to 
compile kicad from source tarball, not to install a binary...
