Subject: [Bug testsuite/36443] [4.3/4.4 Regression]: HOSTCC doesn't work with installed gcc
Date: Mon, 02 Feb 2009 22:00:00 -0000	[thread overview]
Message-ID: <20090202220037.18097.qmail@sourceware.org> (raw)

------- Comment #46 from mmitchel at gcc dot gnu dot org  2009-02-02 22:00 -------
As I understand it, the complaint here is that GCC_EXEC_PREFIX being set
affects HOSTCC, when HOSTCC is itself some other GCC.

But, we have to make sure that the newly built compiler searches the right
directory.  That's why GCC_EXEC_PREFIX is set.  (You can fix this by arranging
to fix GCC's build process, so that components are installed within the build
tree in the same way they would be at install time, and then you can forget all
about GCC_EXEC_PREFIX, -B options, and everything else.  But, it's a huge
project.)

HOSTCC is an arbitrary compiler.  It need not even be a GNU compiler.  DejaGNU,
"make check", etc. set all manner of random environment variables.  Therefore,
if you want to be robust, HOSTCC needs to set/unset any environment variables
relevant to its operation.
