Compiling gambas2 in Opensuse Build Server

[Guillermo Ballester Valor]

Hello,

As some of you know, I build gambas2 rpms using Opensuse Build Server (OBS).
Since a few days ago, the rpms for latest 'opensuse 11.0' and 'opensuse
factory' cannot be built because a extrange problem.

After the rpm package is built in OBS, a program called 'rpmlint' inspect
carefully a lot of things in the recent built rpm. If the 'badness' is over a
threshold then the rpms are rejected.  

The problem here is that there is a lot of files in the examples tree
directories (all in '.gambas' subdirectories) which references to the
complete path of files at compile time, and of course wrong path when
installed. And rpmlint says this is a bad thing,  and add 10000 points of
badness every time it find these files.  As a result the rpms are over
threshold and failed. :(

Any hint to avoid this?. Are necessary all these files under '.gambas'
directory?

Thanks in advance

Guillermo

The .gambas directory is the result of the compilation of the project. The
contents is a list of bytecode files, one for each class file.

How can these binary files reference anything? Or I didn't understand what you
wrote.

Yes, some of these files have strings with complete path of files at compile
time. And rpmlint doesn't like it.

Well, see some lines of rpmlint complain:

gambas2-runtime.i586: E: file-contains-buildroot (Badness:
10000) /usr/share/gambas2/examples/Networking/HTTPPost/.gambas/F
gambas2-runtime.i586: E: file-contains-buildroot (Badness:
10000) /usr/share/gambas2/examples/Drawing/Gravity/.gambas/FABOUT

Lets see the latest file 'FABOUT' with hexdump. I show only the interesting
lines

#hexdump -C FABOUT

Can you see the string '/var/tmp/gambas2-2.7.0-build/'  ?. This is what
rpmlint dislike, because is the buildroot directory at rpm construction time.  

One have to admit that if this complete string points to a needed file, it
will not be found at run time, because that root directory does not exist.
But actually I've just run this gravity example ant it works.

Any light?.

Hello again,

As a workaround, and I will create the subpackage 'examples' . I think all
examples in a package is a nice thing and it also permit to avoid these
blocking problems not building it in some cases, as 'opensuse 11.0'
and 'opensuse factory'.

May I suggest to place (for all distro packages) the examples in a
directory where the user can write too. When loading an example, there
is an alert about permits.

These paths are the path of class at compile time, and are not used at all by
the interpreter. So I think they could be safely ignored. I will remove them
in the future.

The examples are installed globally, so it is logical that only root can write
them. If you need to modify an example, you can easily make a copy of them in
your home directory by using the "save as" menu in the IDE.

OK,
 
I've already built the 'examples' packages in all but opensuse 11.0  and
factory. This trick works and now there are 2.7.0 packages for all opensuse
distros.

I'm thinking about  to compress the 'examples' tree directory after install
stage when building rpm, and then to uncompress the tar.bz2 file in
postinstall stage.

I don't know whether it can work and whether rpmlint will be clever enough to
detect the trick.  I think I must try
