Unable to use this on Mac OSX

[Chuongv]

I create a new cargo project cargo new project --bin Then I add the line to my Cargo.toml [dependencies.rstox] git = "https://github.com/suhr/rstox.git"

I also confirmed that libtoxcore and libtoxav are in my /user/local/lib

Get the following error when trying to build

error: linking with `cc` failed: exit code: 1

Hm. Does it compile with LDFLAGS=-L/user/local/lib?

[Chuongv]

I should of mention that I am using cargo build. Is there a way for me to add a linker flag to it?

I added the /user/local/lib to this, not sure if it's the same thing? But same issue.

Well, weird. But the issue doesn't seem to depend on rstox. Does it compile anything else?

[Chuongv]

I have been going through the rust tutorial and doing the sample programs and they have been compiling fine. But yea, it doesn't seem to depend on rstox. I can't find anywhere in the rstox project where this issue might be. Anyways, feel free to close this one.

[Chuongv]

Closing this one, I don't think this is rstox related. Thanks for the help though! :smile:

@suhr

Hm. Does it compile with LDFLAGS=-L/user/local/lib?

Ooops I didn't add that linker flag correctly. It compiles now. I wonder why cargo doesn't add that originally?

[Chuongv]

Okay figured it out, LIBRARY_PATH was not set. Since cargo/rust looks at that to figure out where the libs are located. I thought it would look at pkg-config to figure out where that is.
