Searching for a C++ API

[R developer]

Hello all,

I have been involved in writing a closed source application that among
other things maintains a checkout from an SVN repository, the application
used to be written in C# so at the moment we are used to SharpSvn. Recently
the decision was made to incorporate the functionality into a mobile c++
app (yes, I do wish we could use a different language, but for now that's
out of our scope).

Is there a C++ library available somewhere?
One that can be used in a closed source app and compiles both on Windows
and Linux (and preferably other platforms like OSx, iOS, Android).
Usage of c++11, boost and/or Qt frameworks is fine as our app already uses
them.

When we started searching; we found several dead ends. Either GPL code
which we can't use or outdated and no longer compiling.

What is the preferred/easiest way of doing a simple checkout/update of a
svn repository folder in a c++ application?
(Any leads will be appreciated as we are quite new to this topic)

Thanks,
Richard

There is no C++ API that I'm aware of. However, the C API can quite
handily be used from C++.

So far i found that rapidsvn contains libsvncpp; but its GPL
https://github.com/RapidSVN/RapidSVN
And there is svnqt, which is old and I couldn't find documentation (LGPL)
https://github.com/MIRAvzw/svnqt
Does anyone know of a better / free to use C++ library?

I'm not that familiar with the C API unless I'm missing something (which is
very well possible) one would have to manage the apr pools himself?
for instance
https://svn.apache.org/repos/asf/subversion/trunk/tools/examples/minimal_client.c
does seem very complex to me for the tasks it performs
is there any easier C example out there?

Kind Regards,
Richard

In the C API, the caller of a function passes to it a result_pool and a
scratch_pool, and decides when to reclaim or free their memory space
(apr_pool_clear / apr_pool_destroy).

svnlook? svnmucc? subversion/tests/cmdline/*.c?

There were C++ language bindings developed in trunk, see
subversion/bindings/cxxhl/. I don't know what the state of the art on
that is --- quite possibly they aren't stable yet --- but they are
Apache Licensed, so perhaps you could build on them. If they don't
yet provide some functionality which you require, please do send
patches :-).

Cheers,

There's hardly any art there that could be in a state. Most of that
effort was making things compile ... there's no real substance there
(but there is a false start or two).

It is not a real C++ library, but there might be some code that you can copy from the SharpSvn library code for your usage. SharpSvn is C++/CLI, to allow operation with the .Net environment, but there is enough plain C++ inside that might be able to get you started with the C library. The code is Apache licensed so you can mostly use it however you like.

Converting CLI is not my best skill, but still thanks for the suggestion :-)

Received a final answer on my request;
libsvncpp from https://github.com/RapidSVN/RapidSVN is now LGPL
