Re: [Opengc-devel] building opengc under redhat 7.3

Hi,

I've also read your more recent message.... using CMake is the correct thing 
to do. The make and configure scripts in the CVS repository are no longer 
functional, as you discovered.

>Prior to these statements, I see a number of warning statements ending with 
>"does not give a valid preprocessing token" (e.g., 
>../../Source/DataSources/ogcDataSource.h:422:3: warning: pasting "->" and

I'm not sure why these warnings are appearing, but they don't indicate a 
problem. They show up on my Linux system as well, although not under 
Windows. I'll have to do some reading to figure out what's happening (they 
are caused by my use of macros in the ogcDataSource.h file, but I'm not sure 
why - the syntax is legal and the code compiles as expected).

As to your current problem with latlongc.o not being available.... that's 
pretty strange. When was your CVS last updated? One thing I might suggest is 
to completely delete both your current CVS and build directories, download a 
fresh copy, and try rebuilding from scratch. It's possible something got 
messed up when you used the configure scripts.

Are you using separate build and source directories? I.e., your source 
directory is named ~/opengc and your build directory is ~/opengcbin (or 
something similar)? If not, I'd suggest doing this under the assumption that 
the makefiles present in the repository could be interfering with the 
makefiles generated by CMake. Incidentally, the executable is named OpenGC 
(note capitalization), and should appear in the root of the build directory 
(i.e. ~/opengcbin/OpenGC ).

Let me know how it goes - I'd like to make sure I'm not the only person who 
can build OpenGC!
