I'm trying to make an Ubuntu app in Vala. I do have knowledge of C++ so the syntax isn't that difficult to learn. But I'm doing something wrong with the needed packages: I need libsoup to communicate with an online API, and a json package. I tried to compile with this command: valac --thread --pkg libsoup-2.4 --pkg json-glib-1.0 json-example.vala

I get following error: /home/brendt/programs/vala/json-example.vala.c:9:26: fatal error: libsoup/soup.h: No such file or directory compilation terminated. error: cc exited with status 256 Compilation failed: 1 error(s), 0 warning(s)

So this makes me think I haven't installed that libsoup package in the correct place. I tried apt-get install, but than Ubuntu says the package is already installed. Than I tried cloning from git, but I don't really find a way to compile the source I get than..

anyone has some suggestions? I probably have to add a correct path somewhere, but I don't know where. regards, brendt

You need to install the development package for libsoup:

sudo apt-get instal libsoup2.4-dev

Thanks, that's the solution indeed –  Brent Roose May 27 '13 at 19:00

So this is a problem that you are experiencing while compiling your app or when using it ?

Show the complete command that you give to compile this application and say if you have this .so library in your LD configuration.

valac --thread --pkg libsoup-2.4 --pkg json-glib-1.0 json-example.vala is how I compile. I never heard of LD configuration or .so library, so could you explain that? that's probably the issue –  Brent Roose May 25 '13 at 10:13
