Unfortunately CC = gcc did not work.
I figured it out at last. The correct incantation is:
COMPONENT_BUILD_ARGS += CC=gcc
That passes "CC=gcc" to the "make".

FWIW I have NEVER ever seen a makefile that used a variable named COMPILER. Moreover,
given that Gnu make supports C, C++ and several flavors of FORTRAN by default, it seems
unlikely that COMPILER is used anywhere. You can test that assertion by not setting
COMPILER and adding an "@echo $COMPILER" line to the all target.
I think you're misreading the make output. It's referencing calling the linker.
The Gnu crowd like to have the compiler frontend do everything. That's OK for
single language packages, but doesn't work very well for a mixture of C++, C &
FORTRAN.
The normal makefile directive is:
CC = gcc
or
CC = /my/path/gcc
with the required tabs at the start of the rule.
In any event, "CC=gcc make library" is unlikely to work.
make library CC=gcc
or make CC=gcc library
are normal invocations of make.
Hope this helps,

Subject: [oi-dev] Specifying GCC as a compiler in a Makefile for simple
library

Hello,
I am trying to build a very simple library.
That library has a Makefile and the correct way to
build it on
Illumos would be to do this:
CC=gcc make library
So I wrote a Makefile for a oi-userland package with the
following
in it:
COMPILER= gcc
include
$(WS_MAKE_RULES)/prep.mk
include $(WS_MAKE_RULES)/justmake.mk
include $(WS_MAKE_RULES)/ips.mk
However, gmake build fails:
symlink cloning
/root/oi-userland/components/library/http-parser/http-parser-2.1
to
/root/oi-userland/components/library/http-parser/build/i86
(cd
/root/oi-userland/components/library/http-parser/build/i86;
/usr/bin/env LD_OPTIONS="-M
/usr/lib/ld/map.noexstk -M
/usr/lib/ld/map.noexdata -M /usr/lib/ld/map.pagealign
-Bdirect -z
ignore" LD_EXEC_OPTIONS="-z
aslr=disable" CCACHE="/usr/bin/ccache"
CC_gcc_32="/usr/gcc/4.9/bin/gcc"
CC_gcc_64="/usr/gcc/4.9/bin/gcc"
CXX_gcc_32="/usr/gcc/4.9/bin/g++"
CXX_gcc_64="/usr/gcc/4.9/bin/g++"
CCACHE_BASEDIR="/root/oi-userland/components/library/http-parser/build/i86"
/usr/gnu/bin/make library)
make[1]: Entering directory
'/root/oi-userland/components/library/http-parser/build/i86'
cc -I. -DHTTP_PARSER_STRICT=0 -Wall -Wextra
-Werror -O3
-fPIC -c http_parser.c -o libhttp_parser.o
cc: -W option with unknown program all
So it is clear that it makes use of the
"COMPILER" variable,
otherwise it would not have had "CC_gcc_32" in
the messages.
However, it looks like it does not pass CC variable to
the Makefile
it eventually calls, so that Makefile is using the
default (and
incompatible) compiler.
Please can you suggest something?
With kind regards,
Denys Rtveliashvili
