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

[Denys Rtveliashvili]

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;

> _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
