Note that - individual flags cannot currently contain spaces, so doing - something like: "-L=foo\ bar" is not possible. -* `CC` - the actual C compiler used. Note that this is used as an exact - executable name, so (for example) no extra flags can be passed inside - this variable, and the builder must ensure that there aren't any - trailing spaces. This compiler must understand the `-c` flag. For - certain `TARGET`s, it also is assumed to know about other flags (most - common is `-fPIC`). -* `AR` - the `ar` (archiver) executable to use to build the static library. - -Each of these variables can also be supplied with certain prefixes and suffixes, -in the following prioritized order: - -1. `<var>_<target>` - for example, `CC_x86_64-unknown-linux-gnu` -2. `<var>_<target_with_underscores>` - for example, `CC_x86_64_unknown_linux_gnu` -3. `<build-kind>_<var>` - for example, `HOST_CC` or `TARGET_CFLAGS` -4. `<var>` - a plain `CC`, `AR` as above. - -If none of these variables exist, gcc-rs uses built-in defaults - -In addition to the the above optional environment variables, `gcc-rs` has some -functions with hard requirements on some variables supplied by [cargo's -build-script driver][cargo] that it has the `TARGET`, `OUT_DIR`, `OPT_LEVEL`, -and `HOST` variables. - -[cargo]: http://doc.crates.io/build-script.html#inputs-to-the-build-script - -## Optional features - -Currently gcc-rs supports parallel compilation (think `make -jN`) but this -feature is turned off by default.

This crate does not ship a C compiler with it. The compiler -required varies per platform, but there are three broad categories: - -* Unix platforms require `cc` to be the C compiler. This can be found by - installing gcc/clang on Linux distributions and Xcode on OSX, for example. -* Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`) - require `cl.exe` to be available and in `PATH`. This is typically found in - standard Visual Studio installations and the `PATH` can be set up by running - the appropriate developer tools shell. -* Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`) - require `gcc` to be available in `PATH`. We recommend the - [MinGW-w64](http://mingw-w64.org) distribution, which is using the - [Win-builds](http://win-builds.org) installation system. - You may also acquire it via - [MSYS2](http://msys2.github.io), as explained [here][msys2-help].
