Installing log4cxx with Visual C++

This post describes how to download and build log4cxx for Visual C++. The following steps assume that you do not have the Platform SDK (2003+) installed. If you do, some steps - noted as "not necessary if you have Platform SDK (2003+) installed" - are not necessary.

Download:

1. Download log4cxx from http://logging.apache.org/log4cxx/download.html. I downloaded apache-log4cxx-0.10.0.zip.
2. Download APR (Apache Portable Runtime) from http://apr.apache.org/download.cgi. I downloaded apr-1.4.2-win32.zip.
3. Download APR-Util from http://apr.apache.org/download.cgi. I downloaded apr-util-1.3.10-win32.zip.

Install:

1. Unzip each archive under C:\3pty, resulting in directories C:\3pty\apache-log4cxx-0.10.0, C:\3pty\apr-1.4.2, and C:\3pty\apr-util-1.3.10.
2. The log4cxx Visual Studio projects assume peer directories named apr and apr-util, so the version-specific directories must be copied (or renamed) accordingly. I choose to copy, in case I need to revert.
3. Copy directory C:\3pty\apr-1.4.2 to C:\3pty\apr, by issuing command: C:\3pty>xcopy /E /I apr-1.4.2 apr
4. Copy directory C:\3pty\apr-1.4.2 to C:\3pty\apr, by issuing command: C:\3pty>xcopy /E /I apr-util-1.3.10 apr-util

Customise:

1. Edit C:\3pty\apr-util\include\apu.hw, changing two lines:
• The line containing #define APU_HAVE_ODBC 1 is changed to #define APU_HAVE_ODBC 0. NOTE: this step is not necessary if you have Platform SDK (2003+) installed.
• The line containing #define APU_HAVE_APR_ICONV 1 is changed to #define APU_HAVE_APR_ICONV 0.
2. Edit C:\3pty\apr-util\include\apr_ldap.hw, changing one line:
• The line containing #define APU_HAS_LDAP 1 is changed to #define APU_HAS_LDAP 0.
3. Open C:\3pty\apache-log4cxx-0.10.0\projects\log4cxx.dsw, navigate into the aprutil project, into the dbd folder, and select the apr_dbd_odbc.c file. Open the settings for this file (right-click Settings, or press Alt-F7), select the General tab, and check Exclude file from build. Do this for all configurations. NOTE: this step is not necessary if you have Platform SDK (2003+) installed. Close Visual Studio.
4. At the project root level - in C:\3pty\apache-log4cxx-0.10.0 - execute the command configure. Do not execute the command configure-aprutil, unless you're working within cygwin.

Build:

1. Open C:\3pty\apache-log4cxx-0.10.0\projects\log4cxx.dsw, select Batch Build from the Build menu, then check the bottom two options log4cxx - Win32 Debug and log4cxx - Win32 Release, and press the Build button. There'll be a bunch of warnings, but at the end you should find it has built the DLLs C:\3pty\apache-log4cxx-0.10.0\projects\debug\log4cxx.dll and C:\3pty\apache-log4cxx-0.10.0\projects\release\log4cxx.dll.
