using Subversion with MinGW projects

[Matthias Miller <Bl...@OutOfHanwell.com>]

I've been trying to link Subversion into a MinGW project with no 
success. So far, I've found two possible approaches.

First, after much research, I found I could use dlltool/reimp to remap 
function names from MSVC to MinGW's name decoration. I've managed to 
successfully link in some of the basic Subversion functions, such as 
svn_client_version. However, it broke as soon as I started pulling in 
more files. It looks like the problem is that the intl and neon 
libraries don't specify a calling convention, so the names are exported 
with the _imp_ prefix. I believe this technique would work if these 
libraries would use the stdcall calling convention.

Second, I could link against a MinGW build of Subversion. However, a 
quick search of the archives shows that this isn't a trivial matter.

Are there any plans for MinGW development packages? Any suggestions on 
where to go from here? Is this a question for the dev mailing list?

Thanks.

Supporting MinGW would allow a number of Qt/GPL applications to use 
Subversion libraries on Windows. This could be very helpful for 
cross-platform Subversion clients.

I've been working on getting a build environment set up for Subversion 
and have been running into a number of problems with some of its 
dependencies. The barrier to entry on projects using Subversion is a lot 
higher if developers need to compiler their own MinGW versions of the 
libraries. Is there any chance a development release package could be 
created with these libraries?

There's been a bunch of work on APR a few months to make it support
MinGW out of the box.  With the current trunk of APR, I've been able
to get a MinGW build of Subversion with just a couple of patches -
you'd have to look at the dev@ archives for those.  If there's enough
interest, I could be persuaded to commit them into Subversion's trunk
too.
