7 | # This eclass contains (or should) functions to get common info |
9 | # @DESCRIPTION: |
8 | # about the toolchain (libc/compiler/binutils/etc...) |
10 | # The toolchain-funcs aims to provide a complete suite of functions |
|
|
11 | # for gleaning useful information about the toolchain and to simplify |
|
|
12 | # ugly things like cross-compiling and multilib. All of this is done |
|
|
13 | # in such a way that you can rely on the function always returning |
|
|
14 | # something sane. |

|
251 | # @USAGE: [econf flags] |
|
|
252 | # @DESCRIPTION: |
|
|
253 | # Sometimes we need to locally build up some tools to run on CBUILD because |
|
|
254 | # the package has helper utils which are compiled+executed when compiling. |
|
|
255 | # This won't work when cross-compiling as the CHOST is set to a target which |
|
|
256 | # we cannot natively execute. |
|
|
257 | # |
|
|
258 | # For example, the python package will build up a local python binary using |
|
|
259 | # a portable build system (configure+make), but then use that binary to run |
|
|
260 | # local python scripts to build up other components of the overall python. |
|
|
261 | # We cannot rely on the python binary in $PATH as that often times will be |
|
|
262 | # a different version, or not even installed in the first place. Instead, |
|
|
263 | # we compile the code in a different directory to run on CBUILD, and then |
|
|
264 | # use that binary when compiling the main package to run on CHOST. |
|
|
265 | # |
|
|
266 | # For example, with newer EAPIs, you'd do something like: |
|
|
267 | # @CODE |
|
|
268 | # src_configure() { |
|
|
269 | # ECONF_SOURCE=${S} |
|
|
270 | # if tc-is-cross-compiler ; then |
|
|
271 | # mkdir "${WORKDIR}"/${CBUILD} |
