Failed to use Log4Cxx in VC++
Hello,
I download the Log4Cxx 0.9.5 source and built the DLL and static library
successfully.
But when I tried to build the "trival.cpp", it failed.
And display the following errors:
Deleting intermediate files and output files for project 'trivial - Win32
Debug'.

Debug/trivial.exe : fatal error LNK1120: 6 unresolved externals
Error executing link.exe.
trivial.exe - 7 error(s), 0 warning(s)
Is there any specific setting in VC that I did not make?

Hello Eric,
Firstly, check that you have compiled both library log4cxx and trivial
example in unicode.
Secondly, check that you had the directory where log4cxx.lib can be
found in "Tools, Options, Directories, Libraries".
