Abhinav

Thank you for reporting this. My errors and apologies for your inconvenience. Congratulations and thank you for your contribution of the video code.

I've submitted a fix to src/CMakeLists.txt to link -ldl (svn:2864)

In July I added code (which is used by exiv2 -v -V) to report run-time library loading. This requires the dynamic loader library to be linked to libexiv2.

Perhaps you could build and let me know if you have further issues. If you're in agreement with the fix, please close the issue.

Thank you Robin.

The fix is working perfect at my end.

This fix breaks compilation on Visual Studio !!!

Please add an appropriate IF in CMake to include the 'dl' library just for specific platforms. On VS I get a fatal error that the compiler can't find 'dl.lib'. Reverting the fix in SVN 2864 resolves that problem, and compilation of exiv2 succeeds.
- Tested on Win8 / CMake 2.8.9 / VS 2012

Thanks,
Daniel

Thanks, Daniel. I'll add the IF to prevent MSVC from wanting libdl. However I'll submit a fix later in the weekend. Unfortunately I can't reopen a closed issue. If my fix causes further pain, perhaps you could report a new issue and mention in the issue report.

Thanks very much for bringing this to my attention. I've very pleased to see that you are using the MSVC/CMake support. Nobody else has reported issues about this and so I concluded "nobody's using this.". Your use and feedback is appreciated. Thanks.
