Newbie config problem

[shakeshuck]

I installed Cobra (Cobra 0.9.4 on .NET CLR v4.0.30319 on Microsoft Windows NT 6.1.7601) yesterday, along with SciTE and the plugins.

For a quick test, I started looking at the sample progs. I wanted to see how GTK looks on Win 7, so tried that sample. It took me a while to get pkg-config installed and seeing the dlls, but I now get the error: Cannot find namespace "Gtk".

I know this is not a Cobra problem, but I'm new to the whole .NET business; if someone could please point me in the right direction I would appreciate it. I am running 64-bit Windows, and as far as I am aware the dlls are 32-bit? Could this be the problem?

Thanks.

Please paste in your compilation line with -v added, and all output.

Hi Charles,

Sorry - I hadn't realized there was a -v on the compiler.

Using:

Code: Select all

cobra -v -pkg:gtk-sharp-2.0 SciTE_test.cobra

The output is:

Code: Select all

I've just had a look and I don't have a Gtk.dll - I didn't see mention on their site of having to install gtk AND gtk-sharp?

[shakeshuck]

It is listed as a dependency, but I have mono running as well (I failed getting Cobra to work in there) and that displays gtk windows from C# (again, I tried a sample). Odd, considering I don't have a gtk.dll?

[Charles]

Are you able to run the sample Gtk# apps listed here?
http://www.mono-project.com/Using_Mono_ ... ows#Gtk.23

Can you get a Gtk# program in C# to compile from the command line as seen here?
http://www.mono-project.com/GtkSharp:_Hello_World

If not, check if you have a Mono prompt that you can bring up which should then have the correct library paths to search for.

Often a problem of the form "cannot do X in Cobra" can be turned into "cannot do X in C#" at which point there is a lot of help via blogs, wikis, stackoverflow, etc. that you can explore.

Hi Charles,

The various help locations hadn't been much help - I did try those before coming here.

I did get it working in the end, though.

It appears Mono (or at least pkg-config, I think it was) doesn't like spaces in the PATH. Installing to the default "Program Files (x86)" on Windows wasn't a good idea.
...and I thought we'd moved on from the 80's

I did have to install Gtk# separately, too.

And remember to set the compiler for x86, also. Sheesh!

Hopefully I can now make some headway and give this nice language some proper testing!

Thanks.

[Charles]

Yeah, I hear you on the spaces. I've had similar problems with pkg-config on Mac. There, I solve them by making a link without spaces.

And the bit width issues feel silly too.
