recently introduced to the octave package causes the octave-forge package to
fail to compile:

This is because cstring isn't a valid C header file, even though it is valid for
C++.  Is this patch strictly necessary?  It seemed that the previous version
octave-3.0.0-3.fc9 compiled OK on GCC 4.3 without that patch.

Comment 1 Alex Lancaster 2008-03-02 12:59:32 UTC
Drat, I guess it was necessary as octave just failed on i386:

http://koji.fedoraproject.org/koji/taskinfo?taskID=484004

Odd that it didn't fail for the earlier mass rebuild against GCC 4.3.  We
obviously need a better solution.

Comment 2 Orion Poplawski 2008-03-02 18:16:11 UTC
Ah, sorry, didn't realize it got called by non C++ code.  Should be able to 
change to:

#include <string.h>



Comment 3 Alex Lancaster 2008-03-03 10:42:35 UTC
OK, with octave rebuilt with the patch updated as per comment #2, octave-forge
has now been successfully rebuilt against it:

http://koji.fedoraproject.org/koji/buildinfo?buildID=40252

So closing the bug.  

Orion or Quentin: has this fix been pushed upstream?  If not, can it be?

Comment 4 Quentin Spencer 2008-03-03 17:34:49 UTC
There is a newer release of octave-forge now available. I was going to try to
get it ready for F-9 but have run out of time. It is possible that the new
octave-forge release already resolves this problem.
