Compilation fails on Ubuntu 14.04 Trusty

[jonathanballs]

I'm getting the following error when compiling with the dub command:

Building sample-dash-game ~develop configuration "application", build type debug.
Running pre-build commands...
cp: cannot create regular file ‘/usr/lib/libsoloud_x86.so’: Permission denied

Error executing command run: dmd failed with exit code 1.

I get why this error appears (missing libraries which can be installed fairly easily) but I feel like this is an issue that should be dealt with by the compiler.

I am also having a very similar problem.

Dub compiles Dash properly until it gets to linking where it tries to link these libraries that don't exist. I'm building on OSX. Here is my output:

Hey, sorry it took me so long to respond to this, I totally forgot it existed :)

It looks like there's 2 issues here, the first being @bonniejools problem with -levent and -levent_pthreads, which should be solvable by installing libevent with apt-get install libevent-dev.

As for the -lsoloud_x86 issue, this is a larger problem. We never quite got libpaths to work correctly, so we just copy the lib to /usr/lib/, which is not ideal. The temporary solution is to either copy libsoloud_x86.so to somewhere in your libpath, or run sudo dub build at least once, to have it copy the file to /usr/lib/ for you.

Let me know if that fixes your issue!
