248# @FUNCTION: econf_build
249# @USAGE: [econf flags]
250# @DESCRIPTION:
251# Sometimes we need to locally build up some tools to run on CBUILD because
252# the package has helper utils which are compiled+executed when compiling.
253# This won't work when cross-compiling as the CHOST is set to a target which
254# we cannot natively execute.
255#
256# For example, the python package will build up a local python binary using
257# a portable build system (configure+make), but then use that binary to run
258# local python scripts to build up other components of the overall python.
259# We cannot rely on the python binary in $PATH as that often times will be
260# a different version, or not even installed in the first place. Instead,
261# we compile the code in a different directory to run on CBUILD, and then
262# use that binary when compiling the main package to run on CHOST.
263#
264# For example, with newer EAPIs, you'd do something like:
265# @CODE
266# src_configure() {
267# ECONF_SOURCE=${S}
268# if tc-is-cross-compiler ; then
269# mkdir "${WORKDIR}"/${CBUILD}
270# pushd "${WORKDIR}"/${CBUILD} >/dev/null
271# econf_build --disable-some-unused-stuff
272# popd >/dev/null
273# fi
274# ... normal build paths ...
275# }
276# src_compile() {
277# if tc-is-cross-compiler ; then
278# pushd "${WORKDIR}"/${CBUILD} >/dev/null
279# emake one-or-two-build-tools
280# ln/mv build-tools to normal build paths in ${S}/
281# popd >/dev/null
282# fi
283# ... normal build paths ...
