Fails to compile

[phdoerfler]

Hi,

I get the following error when trying to compile imageproc:

$ cargo build
   Compiling imageproc v0.1.0 (file:///Users/phi/Documents/workspace/rust-imageproc)
failed to run custom build command for `imageproc v0.1.0 (file:///Users/phi/Documents/workspace/rust-imageproc)`
Process didn't exit successfully: `/Users/phi/Documents/workspace/rust-imageproc/target/debug/build/imageproc-f73ade026b903961/build-script-build` (exit code: 101)
--- stdout
running: "make" "-j4"

--- stderr
make: *** No targets specified and no makefile found.  Stop.
thread '<main>' panicked at 'assertion failed: t!(cmd . status (  )).success()', build.rs:15

I have written a sobel convolution kernel and would like to submit a pull request for this but I'd like to test it before I do that.

It seems I forgot to call

git submodule update --init

I do seem to have trouble compiling FreeImage itself now. I am on OS X and have FreeImage installed via the package manager (homebrew). Is there any way I can avoid the compilation of FreeImage and use the installed version instead?

An alternative solution is to replace these lines in build.rs:

    run(Command::new(make())
        .arg("-j4")
        .current_dir("3rdparty/FreeImage"));
    run(Command::new("cp")
        .arg("3rdparty/FreeImage/Dist/libfreeimage.a")
        .arg(format!("{}/", out_dir)));

with these:

    run(Command::new("cp")
        .arg("/usr/local/Cellar/freeimage/3.17.0/lib/libfreeimage.a")
        .arg(format!("{}/", out_dir)));

depending on where freeimage is installed locally. This is the location homebrew installed it in.

With this change I was able to get imageproc to compile.
