KP under mono in OS X: not working...

[Joseph_N]

I have tried twice to install and run KeePass under mono in OS X, and it won't work.

After installing mono, Quartz, and KP from the zipped file, I opened Terminal. I switched to the Applications/KeePass directory (which I had created for the KP files), and then ran "mono KeePass.exe" without the quotes. Here is the Terminal output. What's wrong? All help much appreciated.

Have you tried modifying KeePass.config.xml per this thread?
https://sourceforge.net/p/keepass/discussion/329221/thread/6a0d9af8

cheers, Paul

[Joseph_N]

Thanks, Paul. No, I looked for solutions but missed that one. I will try it when I get back to that machine in a day or two. I'll update this thread.

[David Lechner]

The root of the problem is:

System.DllNotFoundException: libgdiplus.dylib

It can't find libgdiplus.dylib, so either mono is not installed properly or you have an issue with library search paths.

[Joseph_N]

Paul: Tried it on another machine. Didn't work. There's no ~.config.xml file, just a ~.config file, which doesn't have the line referred to in that post.

David: Thank you. I've tried this on two machines, and, on one, installed mono from two different builds and sources (the project itself, and the KP2-on-mac page listed on the KP downloads page). Since mono doesn't seem to be installing the file, I will look for it on the web and see if I can get the paths correct. I'm not fluent on OS X, so it may be a couple of days until I can run through some attempts. Any suggestions welcome.

[David Lechner]

You can find the file by running locate libgdiplus.dylib.

You shouldn't have to do this, but you can launch using LS_DYLIB_PATH=<path that you found from the previous command> mono KeePass.exe to force it to look for the library in this path.

I have exactly the same problem. I installed mono 3.8.0 and XQuartz 2.7.6 on OSX (10.9.5). Then unzipped KeyPass-2.27.zip.

I found the libgdiplus.dylib file on my system at /Library/Frameworks/Mono.framework/Versions/3.8.0/lib/libgdiplus.dylib, so I ran the following command:

LS_DYLIB_PATH=/Library/Frameworks/Mono.framework/Versions/3.8.0/lib/libgdiplus.dylib mono KeePass.exe

But the exception I get is still the same...

[Tomasz Adamusiak]

Try LD_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/3.8.0/lib mono KeePass.exe

Note it only worked for me after downgrading mono to 3.6.0

[David Lechner]

Yes, the library path should just be the folder name and not include the file name. i.e LD_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/3.8.0/lib

Could be that something broke in mono 3.8.x.

You can actually have more than one Mono version installed at a time. I believe just checked and my default mono version is 2.10.x, which works without having to specify the library path. Up till now, I thought I was using a newer version of Mono.
