error in `corto create myApp` #536

Closed KrishnaPG closed 8 years ago

KrishnaPG commented 8 years ago

After fresh installation of corto, following the tutorial steps (here), the create command failed as below:

$ corto create myApp
corto:  create application 'myApp'
corto: failed to start process 'rake'

The myApp folder is created fine. Looks like the corto run command is looking for rake which is not found.

I thought rake was required only for building the corto itself and not the user projects?

Anyway, if rake is indeed required for corto run, then I think letting curl https://corto.io/install | sh command install it as prerequisite would be good idea as part of the corto installation itself (rather than user having to install it separately).

After installing rake with the command sudo apt-get install rake, the corto run command worked fine. It printed the output.

But I would suggest the rake installation step to be integrated into the corto installation step, just in case.

@KrishnaPG ah, the documentation should be clearer about that. The corto create tool uses the rake-based buildsystem. It is a simple wrapper around creating a corto project that helps you to setup a project very quickly.

It is possible to setup a project with another buildsystem manually, but then the corto create tool won't work. Essentially for a non-rake based project, you would need to manually link with libcorto.so and include the package repository:

gcc src/myApp.c -I/usr/local/include/corto/0.2 /usr/local/lib/corto/0.2/corto/libcorto.so -o myApp

Thanks @SanderMertens No issues. Just thought of suggesting to add the rake dependency to the corto installation step itself. Will help the beginners.
