[SOLVED] Build of Gambas 3.6 RPM fails at symlinking of TTF

[tleedavidson]

Hello,

I am trying to build an RPM of the newly released version of Gambas (3.6.0), which I downloaded from SourceForge (http://sourceforge.net/projects/gambas/ ... .0.tar.bz2), on my Mageia 3 box. (I figured it was worth a try.)

What I have done is take gambas-llvm-3.3.patch and gambas3.desktop from http://svnweb.mageia.org/packages/cauld ... t/SOURCES/ and put them in ~/rpmbuild/SOURCES along with the Gambas 3.6.0 tarball. Then I grabbed gambas3.spec (Rev. 750063) from http://svnweb.mageia.org/packages/cauld ... ent/SPECS/ and put it into ~/rpmbuild/SPECS.

I modified gambas3.spec ever so slightly: "Version: 3.5.4" became "Version: 3.6.0"; "Release: %mkrel 5" became "Release: %mkrel 1"; and I uncommented lines 595 and 596 to enable inclusion of the JIT (Just-In-Time compiler) component.

From a console in the ~/rpmbuild/SPECS directory, I executed:

Code: Select all

rpmbuild -ba gambas3.spec

It seems to build just fine. But when it gets to %install, it chokes on:

Code: Select all

ln -sf %{_datadir}/fonts/TTF/dejavu/DejaVuSans.ttf %{buildroot}%{_datadir}/gambas3/gb.sdl/DejaVuSans.ttf

"No such file or directory"

There is no gb.sdl directory in %{buildroot}%{_datadir}/gambas3/. All that is there is control, examples, icons, and info.

I understand that the gb.sdl component requires that font as per line 1028 of the spec file: "Requires: fonts-ttf-dejavu". But do I really need that symbolic link for a successful install? Or could I perhaps get it to work by placing the symlink in %{buildroot}%{_datadir}/gambas3/ ?

Or ... is it silly of me to even try making this whole idea work?

(Warning: I should probably admit that I know just about enough about building RPMs, to be dangerous.)

You don't need it for a successful install, rpm doesn't care about that symlink. Question is whether gambas requires that symlink and works properly.
Simply comment it out and try. Just checked the fedora package and there seems no such thing. http://pkgs.fedoraproject.org/cgit/gamb ... mbas3.spec

Thank you for your quick response, Doktor.

I questioned the Gambas-user list about that font and found that it has been replaced by a default font which is embedded in the SDL library. So, it is not needed.

After commenting out the symlink command and the 'Requires' line, I tried to build again. I got further this time, but another error:

Processing files: gambas3-gb-sdl-3.6.0-1.mga3.i586
error: File not found: /home/muck/rpmbuild/BUILDROOT/gambas3-3.6.0-1.mga3.i386/usr/share/gambas3/gb.sdl

RPM build errors:
File not found: /home/muck/rpmbuild/BUILDROOT/gambas3-3.6.0-1.mga3.i386/usr/share/gambas3/gb.sdl

The %files section for gb-sdl has this line:
"%{_datadir}/%{name}/gb.sdl"

And, given the error I first reported combined with the fact that all other %{_datadir}/%{name}/ file-spec lines append a subdirectory, I think that might be left-over from the external font requirement. So, I commented that out and am trying again. Will report back.

Success!!

I had to do a bit more editing to the SPEC file than just to clear out vestiges of that deprecated TrueTypeFont requirement. I also had to add %package sections to accommodate some new components (inotify, markdown, & gb-media-form) and the sqlite2 component that is still included in the source but not packaged by the SPEC file. There were also some "orphan" files that were included but not packaged.

I have attached the resulting gambas3.spec file (as gambas3.spec.txt because, "The extension spec is not allowed."). I would have attached a diff-file also, but, for some reason, my diff picked out lines that were identical even down to the encoding.

Now to summarize for anyone else wishing to do the same, here are the steps to take.

First, build the RPM.

1. Ensure your system is set up to build RPMs. If you're unsure, read Packagers RPM tutorial up to section "3.3 Create .rpmmacros file" -- you don't need to do that for what we'll be doing.
2. Downlad the Gambas 3.6.0 source archive from http://sourceforge.net/projects/gambas/ ... 2/download to your ~/rpmbuild/SOURCES directory.
3. Download gambas-llvm-3.3.patch and gambas3.desktop from http://svnweb.mageia.org/packages/cauld ... t/SOURCES/ to your ~/rpmbuild/SOURCES directory.
4. Download the attached gambas3.spec.txt file to your ~/rpmbuild/SPECS directory (not SOURCES). Rename it to remove the ".txt" extension.
5. From a console, execute:
   

   Code: Select all

   rpmbuild -ba ~/rpmbuild/SPECS/gambas3.spec

Now, if your system is as slow as mine, go brew a pot of coffee, or go for a walk, or maybe take that long awaited trip around the world...

When the RPM build completes without errors (and we know it will, right?), check the ~/rpmbuild/RPMS directory. There should now be two subdirectories there. A noarch directory and a directory named according to your system's architecture, ie. i386, i586, x86_64 as noted in the Packagers RPM tutorial.

They're there? Great! Install your new package:

Code: Select all

sudo urpmi ~/rpmbuild/RPMS/noarch/*.rpm ~/rpmbuild/RPMS/$(arch)/*.rpm

Be sure to replace "$(arch)" with the correct designation for your system's architecture.

You can ignore the warnings saying the packages aren't signed. They don't need to be; you know who built them. And, when installation completes...

You should now have a working Gambas 3.6.0.
