Hi Betty,
The Makefiles in log4cpp are automatically generated from the
Makefile.am files by automake/autoconf. Editting a Makefile.am will only
work if you have the automake and autoconf packages installed. Also the
target 'testCategory', etc. will not be build if you type just 'make',
since the are not part of the default make target. (you need to do 'make
check'.)
So to get started it's probably easier to try the hand written
one-liner. You almost got it right, except for two things:
1) Since the source is C++ use 'g++' instead of 'gcc' or else the
compiler won't link the necessary standard C++ libraries
2) It does link the log4cpp library.
I assume you've build and installed log4cpp
using './configure --prefix=<installdir> ; make ; make install'
Then you can ask the tool log4cpp-config which parameters you need for
linking log4cpp with 'log4cpp-config --libs'.
It will return something like '-L<installdir> -llog4cpp', maybe followed
by '-lsocket -lnsl' or something similar.
The same trick also works for the compile flags.
In short, try:
g++ `log4cpp-config --cflags` `log4cpp-config --libs` -o testLog
testLog.cpp
Good luck,
