Is there any way to tell for certain if gcc uses the GNU or Sun linker
on Solaris, in a program? I would also like to do the same for the
assembler, though that is less important to me.
I can tell on my machine it uses the Sun linker and assembler
$ gcc -v
Using built-in specs.
Target: sparc-sun-solaris2.10
Configured with: ../gcc-4.4.1/configure
--prefix=/usr/local/gcc-4.4.1-sun-linker/ --with-as=/usr/ccs/bin/as
--without-gnu-as --with-ld=/usr/ccs/bin/ld --without-gnu-ld
--enable-languages=c,c++,fortran --with-mpfr-include=/usr/local/include
--with-mpfr-lib=/usr/local/lib --with-gmp-include=/usr/local/include
--with-gmp-lib=/usr/local/lib CC=/usr/sfw/bin/gcc CXX=/usr/sfw/bin/g++
LDFLAGS='-R /usr/local/lib -L /usr/local/lib'
Thread model: posix
gcc version 4.4.1 (GCC)
Looking there I see '--without-gnu-as' and '--without-gnu-ld', but there
is no guarantee someone uses those options when configure gcc. Here it
is even more clear, with -with-ld=/usr/ccs/bin/ld and
--with-as=/usr/ccs/bin/as. But what happens if I don't specify any of
this when I build gcc? Would it just find the first linker and assembler
in the path? In which case, how could I now determine what it uses?
