Issues with GPS on Xubuntu

Issues with GPS on Xubuntu

[Martyn Pike]

Hello.  I have recently installed GNAT GPL 2010 onto x86-64 Xubuntu.  All 
is well but I do not have any compiler options under the Ada tab on the 
Project Dialog.

All other tabs have switches.  Have I missed something during transition 
from XP ?

I do get a warning on startup about missing libpng12.so - related ?

thanks. Martyn

I don't know, maybe check your $PATH as you do not normally install
GNAT GPL in the default $PATH. For this reason it is critical that you
follow the installation instructions completely and precisely.

I don't think so. That library is related to Portable Network
Graphics, not GNAT. But it might indeed indicate a problem with the
$PATH or $LD_LIBRARY_PATH that the GPS process sees.

Why not use the Debian packages? They come preconfigured and work
right out of the box. Check out packages gnat and gnat-gps.

I mentioned them because you said you were using XUbuntu, which is a
derivative of Debian.  So, the Debian packages are normally accessible
through the package manager:

$ sudo aptitude install gnat gnat-gps

For more info, see the user's guide about package management.

In the case the libpng12.so library is missing
---------------------------

On Debian & derivatives Linux distributions, you can easily know to
what package a missing file belongs with apt-file.

$ sudo aptitude install apt-file
$ apt-file update
$ apt-file search libpng12.so
libpng12-0: /lib/libpng12.so.0
libpng12-0: /lib/libpng12.so.0.42.0
libpng12-dev: /usr/lib/libpng12.so
lsb-build-desktop3: /usr/lib/lsb3/libpng12.so
$ sudo aptitude install libpng12-dev libpng12-0

The latter command will install the libpng12-dev & libpng12-0 packages
and thus the libpng12.so missing library.
Then relaunch GPS (GNAT GPL) again to sort out if that was the
problem.

That _should_ solve your problem.

Hi Ludovic.

Yes I was able to install the packages - thanks for the pointer. It 
installed 4.4.3 but I still get the same issue that the Ada tab on the 
switches page is empty except for what looks like space for command line 
arguments to be entered.

Thanks David. That did indeed solve the problem.

TBH, since I don't use GPS and only had a cursory look at it, this
one-line entry box never struck me as odd until you complained about it.
IIUC, the Ada page should be full of check boxes and other nifty
widgets, right?

In addition I see this in the Messages pane:

This seems like a bug in the gnat-gps package that should not be present
in the GNAT GPL 2010 binary distribution.  Was that what you meant?

Anyway I've filed a bug report and will try to find the time to correct
that.  See http://bugs.debian.org/596385

Yes that is correct.

Thanks Ludovic.
