The build.xml in the SVN for both the log4j 1.2 and 1.3 branches will
build NTEventLogAppender.dll using MinGW's gcc (see bug 37866, http://
issues.apache.org/bugzilla/show_bug.cgi?id=37866). Unless you have a
specific need to use Borland C++, I would recommend using the Ant
build. The specific cause of your compilation issues is that the
code requires header files generated by javah to be on the include path.
To build NTEventLogAppender.dll:
1. Download MinGW-3.1.0-1.exe from http://mingw.sourceforge.net/
download.shtml
2. Run downloaded file to install MinGW
3. Check out log4j source from Subversion
svn co http:://svn.apache.org/repos/asf/logging/trunk/log4j/trunk log4j
or
svn co http:://svn.apache.org/repos/asf/logging/log4j/branches/v1_2-
branch log4j
4. Copy build.properties.sample to build.properties
cd log4j
copy build.properties.sample build.properties
5. Place MinGW on the path
path c:\mingw\bin;%PATH%
6. Build NTEventLogAppender
ant build.nt
This step will require that you build log4j.jar first which may
require downloading some supporting jars and modifying
build.properties. However, if you are already set up to build log4j,
then you should know your way around these issues.
If you really want to use Borland C++, then you can look at the
build.nt target in build.xml for the step by step. You'd want to use
the Borland Resource Compiler (brc or brc32 if I remember correctly)
or Microsoft Resource Compiler (rc) instead of windres to compile
EventLogCategories.rc and NTEventLogAppender.rc and Borland C++
(bcc32) instead of gcc to compile nteventlog.cpp.
If you don't care about building the DLL, you can extract it from any
older log4j (say 1.2.8) from http://archive.apache.org/dist.
