Users of Fedora 10, 11 or 12 will find that the openmotif-devel package
from the RPM Fusion repository causes a problem for building
ProofPower. The version of the package provided by MotifZone works fine.
As the Fedora distribution contains only those packages that are truly
open source, many users will be using the RPM Fusion repository because
it provides a lot of useful software that is not open source, e.g. video
drivers. At some point last year, RPM Fusion started to provide
OpenMotif packages.
Even if Fedora users installed the OpenMotif RPMs from MotifZone, once
the RPM Fusion repository is in use, the command
yum update
(to update all packages) will attempt to replace these with the later
versions from RPM Fusion.
Unfortunately, the openmotif-devel package supplied by RPM Fusion
doesn't put the header files in the same place as the package from
MotifZone. They have moved as follows:
/usr/include -> /usr/include/openmotif/
/usr/lib -> /usr/lib/openmotif/
The contents of the package from RPM Fusion can be listed with the
following command:
rpm -qpl
http://download1.rpmfusion.org/nonfree/fedora/releases/12/Everything/i386/os/openmotif-devel-2.3.2-5.fc12.i686.rpm
This is a problem for ProofPower installation because the PPMOTIFHOME
environment variable used by configure must provide a directory that has
include/Xm/
under it but no such directory exists with header file relocated as
above. (I think there could be an issue beyond the configure script
because PPMOTIFHOME doesn't seem to be used anywhere, namely in any
include paths for compilation or linking.)
To work around this, prevent Yum from updating the OpenMotif packages by
changing the file
/etc/yum.conf
(as root) so that the line starting
exclude=
mentions openmotif* . If there is no such line, add one anywhere after
the initial [main]. On my computer I have
exclude=polyml,mlton,lesstif*,openmotif*
If Yum has already updated the OpenMotif packages, you can revert back
to the MotifZone packages by entering the following commands (as root):
RELEASE=fc10 # choose from: fc8, fc9, fc10 (use fc10 for fc11, fc12)
ARCH=i386 # choose from: i386, x86_64
rpm -e openmotif openmotif-devel
rpm -ivh \
http://www.motifzone.org/files/public_downloads/openmotif/2.3/2.3.2/openmotif-2.3.2-1.${RELEASE}.${ARCH}.rpm
\
http://www.motifzone.org/files/public_downloads/openmotif/2.3/2.3.2/openmotif-devel-2.3.2-1.${RELEASE}.${ARCH}.rpm
It should be possible to copy and paste the above commands into a
terminal. Of course, reverting the OpenMotif installation may break
other programs on your system...
