How do I compile mod_dontdothat on Windows

Question

I cannot seem to compile mod_dontdothat on Windows. Has anybody managed to achieve this?

Edit:

I've tried compiling the file according to the readme on the site and I've tried to add extra libs to reduce the link errors. Ive got the following installed:

1. Apache 2.2.9
2. Visual Studio 2008
3. ActivePerl
4. apxs-win32 from ApacheLounge
5. Subversion libs and headers

I run the following command line:

C:\Program Files\Apache Software Foundation\Apache2.2\bin>apxs -c -I ..\include\
svn_config.h -L ..\lib -L C:\Progra~1\Micros~1.0\VC\lib -l apr-1.lib -l aprutil-
1.lib -l svn_subr-1.lib -l libapr-1.lib -l libaprutil-1.lib -l libhttpd.lib -l l
ibsvn_subr-1.lib -l mod_dav.lib mod_dontdothat.c

Then I get the following errors:

I'm not too much of a C guru, so any help in finding these unresolved external symbols will be much appreciated!

Answer 1

I managed to compile the module. Prerequisites:

• Apache 2.2.11
• apxs-win32 from www.apachelounge.com
• Visual Studio 2005
• Active Perl 5.8.8 (you need perl for apxs-win32 installation)

Here is a step-by-step guide. Download these packages:

• http://subversion.tigris.org/files/documents/15/44595/svn-win32-1.5.5_dev.zip (we need the libraries and header files from this package)
• http://subversion.tigris.org/downloads/subversion-1.5.5.zip (we will be using the mod_dav_svn sources to compile a static lib)

Unpack the dev package to c:\temp\svn and the other package to c:\temp\svn-src and the mod_dontdothat files to C:\Temp\dontdothat.

One of the dependencies of mod_dontdothat module is mod_dav_svn module. Unfortunately you'll find the mod_dav_svn binary only as a shared library (DLL). You cannot link against a DLL. So the first step is to build a static mod_dav_svn library:

cd C:\Temp\svn-src\subversion\mod_dav_svn
apxs -c -I ..\include  -L C:\Temp\svn\lib -l libsvn_delta-1.lib -l libsvn_diff-1.lib -l libsvn_fs-1.lib -l libsvn_fs_base-1.lib -l libsvn_fs_fs-1.lib -l libsvn_fs_util-1.lib -l libsvn_repos-1.lib -l libsvn_subr-1.lib -l libapr-1.lib -l libaprutil-1.lib -l libhttpd.lib -l mod_dav.lib -l xml.lib  -n mod_dav_svn mod_dav_svn.c activity.c authz.c deadprops.c liveprops.c lock.c merge.c mirror.c repos.c util.c version.c reports\dated-rev.c reports\file-revs.c reports\get-locations.c reports\get-location-segments.c reports\get-locks.c reports\log.c reports\mergeinfo.c reports\replay.c reports\update.c

The apxs call will print the commands it executes. The last command is a link call which builds the DLL. Copy it replace "link" by "lib", remove the "/dll" param, and change the "out" param file name to "libmod_dav_svn.lib". You should get something similar to:

lib kernel32.lib /nologo /subsystem:windows /machine:I386 /libpath:"C:\PROGRA~1\APACHE~1\Apache2.2\lib" /out:libmod_dav_svn.lib  /libpath:"C:\Temp\svn\lib"  libsvn_delta-1.lib libsvn_diff-1.lib libsvn_fs-1.lib libsvn_fs_base-1.lib libsvn_fs_fs-1.lib libsvn_fs_util-1.lib libsvn_repos-1.lib libsvn_subr-1.lib libapr-1.lib libaprutil-1.lib libhttpd.lib mod_dav.lib xml.lib   reports\update.lo reports\replay.lo reports\mergeinfo.lo reports\log.lo reports\get-locks.lo reports\get-location-segments.lo reports\get-locations.lo reports\file-revs.lo reports\dated-rev.lo version.lo util.lo repos.lo mirror.lo merge.lo lock.lo liveprops.lo deadprops.lo authz.lo activity.lo mod_dav_svn.lo

You will get some link warnings. You can ignore them. Copy the libmod_dav_svn.lib to the mod_dontdothat directory. Now start the compilation process for mod_dontdothat:

C:\Temp\dontdothat
apxs -c -I C:\Temp\svn\include -L C:\Temp\svn\lib -l libsvn_subr-1.lib -l libapr-1.lib -l libaprutil-1.lib -l libhttpd.lib -l mod_dav.lib -l xml.lib -l libmod_dav_svn.lib    mod_dontdothat.c
apxs -i -n dontdothat mod_dontdothat.so

This should do the trick.

Answer 2

Googling around I've got

• mod_dav_svn.lib for _dav_svn_split_uri
• intl3_svn.lib for all things _libintl
• shell32.lib for SHGetFolderPath
• advapi32.lib for Registry stuff
• ole32.lib for CoInitialize and it's ilk
• inflate and deflate smell like zlib1.lib or something like that

Hope that helps.

Answer 3

Thanks for revising the question.

It looks like a definite linker issue. I see that the first undefined symbol is related to webdav. Are you sure you have that library in the right place? I see you give a nice long path with lots of svn libs, maybe it's possible you overlooked just one?
