How to list errors from a custom external command in Vim

When using vim, I would like to use a custom command to build my projects.

The build command looks as following

matmake2 -t gcc-debug

Optimally I would like to use vims built in error buffer, so that I could use :copen to view and navigate the errors, but the results from running

:!matmake2 -t gcc-debug

is not picked up by vims error parser, and when trying to set

set makeprg='matmake2 -t gcc-debug'

in my vimrc-file, I get the error "Unknown flag -t".

Is there any way so that I can run my custom build command with arguments in a way so that vims error parser will pick it up?

The errors picked up by Vim end up in the quickfix list. There are many commands that can populate that list but :!<whatever> is not one of them.

What you need is the :help :make command, which calls the program defined with :help 'makeprg', parses its output against the various patterns in :help 'errorformat', and populates the :help quickfix list with valid errors.

You were on the right track with:

set makeprg='matmake2 -t gcc-debug'

but string options don't take expressions as value. You can set makeprg this way:

set makeprg=matmake2\ -t\ gcc-debug

or that way:

let &makeprg = 'matmake2 -t gcc-debug'

with either of the two lines above in your config, you should be able to do :make % and then :copen to see your errors.
