Fail to link, can't find libhttp_parser

[gentoo90]

On linux cargo test fails to link executable.
Seems like it fails to find libhttp_parser.so which is installed in the system.

and linkage is successful .

Aha I had a feeling that something like this would crop up...

This'll probably need to be fixed by scraping the build logs of libgit2 or perhaps scraping the generated pkg-config file to see how http_parser was linked.

Out of curiosity, do you know why libhttp_parser.so is installed locally? Do you know what other package required it?

[gentoo90]

  net-libs/http-parser-2.3 pulled in by:
    dev-libs/libgit2-0.22.3 requires net-libs/http-parser
    dev-util/cargo-0.8.0 requires net-libs/http-parser
    net-libs/nodejs-0.12.6 requires >=net-libs/http-parser-2.3

(Gentoo linux)

Thanks!
Also, this breaks cargo build (this is how I encountered it in the first place). So please update cargo's Cargo.lock to use libgit2-sys-0.3.10

[alexcrichton]

Sure thing! Done in rust-lang/cargo#2323

Just got this error on MSYS2 when compiling rust from git:

error: failed to compile `cargo-vendor v0.1.4`, intermediate artifacts can be found at `D:\msys64\tmp\cargo-install.HeqskRREZaIC`

Caused by:
  Could not compile `cargo-vendor`.

Both libgit2 and http-parser are installed but in different path than the fix checks: /mingw64/lib/pkgconfig/libgit2.pc

I'd like to use rustbuild for MSYS2 Rust packages starting with next version but it have to compile in environment with (almost) all packages installed .

EDIT: Apparently path is fine but function is returning too soon.
