[Qgis-developer] Compiling against geos-3.0.0rc4

[Mike Leahy]

Tim,

I can clarify that without any patching, both 0.8.0 and the svn trunk
will compile and run fine with geos-3.0.0rc3.  If I then uninstall rc3,
install rc4, and add a symbolic link that points from libgeos-3.0.0rc3
to libgeos-3.0.0rc4, QGis will still run.  So it's binary compatible at
least.  It just doesn't seem to like compiling against rc4.

When the svn trunk is compiled against rc4, the output is essentially
the same as the first error I was getting with the release 0.8 version.
 The only difference is that if I make clean then make again with the
svn trunk doesn't give me a different error (as the release version had
been).  So...does this then point to a problem with some changes with
geos-3.0.0rc4?

P.S.: How do you set the install libdir to /usr/lib64 with the cmake
setup?  With the ./configure script, I would just add
--libdir=/usr/lib64.  I tried using -D LIBRARY_OUTPUT_PATH=/usr/lib64,
but unless I got something wrong, that option seems to put the libraries
there during make, rather than make install.  I also tried
CMAKE_INSTALL_LIBDIR and CMAKE_INSTALL_RPATH, but neither of those did
the trick.

Mike
