Building Proj4 on Windows fails due to linking issues

[felixcremer]

If I try to build Proj4 on Windows it fails with the following error, but it works if I run it as administrator:

Thanks for reporting. I've been trying to make a new BinaryBuilder build which will hopefully fix this issue, but did not manage to get a build complete on all platforms:

https://travis-ci.org/JuliaGeo/PROJBuilder

I guess we could try rebuilding the current PROJ version as well, not sure if that will help though.

According to your error, it seems that:
Warning: On Windows, creating file symlinks requires Administrator privileges

So you could try running Julia as admin and try to build this package again.

[visr]

Yeah he did so as mentioned above. However for those with no admin rights it is still an issue. Nowadays BinaryBuilder avoids symlinks for this reason, so if we can get a new build this should be fixed.
