[fdo-users] FDO Compile error (libxalan-c)

[john spitzer]

Hi,
When building FDO from source on Ubuntu I got the following g++
compile time issue:
g++ -O2 -DNDEBUG      -fno-elide-constructors -Wall -fPIC -DLINUX
-D_REENTRANT -DXALAN_INMEM_MSG_LOADER -c

make: *** [all] Error 2

This was fixed by including in the source of
/home/jjs/OpenSource_FDO/Thirdparty/apache/xml-xalan/c/src/xalanc/XalanDOM/XalanDOMString.cpp
the following include directive :

#include <cstring>

There are quite a few cases where this is necessary to achieve a clean
compile of xml-xalan.
gcc/g++ is the standard compiler on Linux.
The passage of environment variables between shell script is a famous
Unix gotcha. I did not bother to Google it, but you can give it a try
to get some background on this issue.
What really causes most grief in migrating systems developed under
Windows onto Unix is case-sensitivites of system names(File names etc)
- windows is case insensitive while unix is case sensitive.

Hope this is of some assistance,
Cheers,
John
