GHC's configure script does not honour CC env var
./configure --help
tells us that:
...
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

However, neither
-
CC=clang-3.8 ./configure
, nor ./configure CC=clang-3.8
has any effect. ./configure
keeps using the /usr/bin/gcc
in $PATH
.
The only invocation that has the desired effect is
./configure --with-gcc=clang-3.8
However, this is utterly surprising and confusing to experienced developers who are used to Autoconf ./configure
scripts adhering to the conventions regarding CC
, and contradicts the --help
message.
