[mapguide-users] building 64bit openmapguide on rhel 5.4

[kfwebb at bombasticlocution.com]

Hello Adam, Rajeev, and others interested in 64bit MapGuide,

I thought I had the problem solved last week. I got FDO and MapGuide to
compile on a x86_64 installation of Fedora Core 8 (a torturous
experience). When I tested using the Sheboygan.mgp sample data, mgserver
threw an FDO exception related to the ConvertUTF16toUTF32() routine in
Fdo. It was then that I realized I had contract work to do and I didn't
have the time it would take to do a thorough job on Fdo and any other
packages needing work, so I stopped my 64-bit installation and installed
on an ancient 32-bit box so that I could get some work done. (I am still
debugging the 32-bit install - nothing is ever easy in this business).  

To answer your direct question, here is how I got around the DWFTimer
issues. My thinking is that DWF is an Internet Explorer only viewer, not
much use for today's browser market. I also didn't know what other
dependencies there were for the DWF library so I just wanted to make it
compile and not ever use the viewer. I copied the dwfcore/x86/Core.cpp,
and dwfcore/x86/Timer.cpp files into the dwfcore directory. I then
edited Timer.cpp to change the 32-bit assembler into 64-bit assembler,
register name changes only. I added Timer.cpp and Core.cpp to the
dwfcore Makefile and Makefile.am for the libdwfcore_la_SOURCES tag.

In general I had to sprinkle around alot of -fPIC directives in numerous
spots, and I changed all of the build_oem.sh entries that were 
--enable-static --disable-shared

to

--enable-shared --disable-static

The change to dynamic linking required adding some -l___ and -L____
directives as called for.

I hope to go back to the 64-bit build when I have time, but maybe the
2.2 version will be out by then. 

Good luck!

Kevin Webb
