Oops, sorry for bad wording. Of course, you can install gcc without the other
libraries, but the compiler cannot compile anything: the compilation stage
(cc1) cannot run without all three libraries. Hum, cc1 is installed in
/usr/libexec/i486-slackware-linux/4.7.1, so I realize that I have installed a
32 bit version of Slackware [beginner error, I looove learning :-( ]. Anyway,
I am almost sure that the lib{gmp,mpfr,mpc} dependency is the same on x86_64.
Though there may be some added complexity due to the lib{,64} "duality"...
With what I have installed up to now (I wanted to reproduce Hazel Russman's
results, so I have installed a small part of the distro. Needs to be
completed...):
------------------------
bash-4.2# ldd /usr/libexec/gcc/i486-slackware-linux/4.7.1/cc1
linux-gate.so.1 (0xf776d000)
libmpc.so.2 => not found
libmpfr.so.4 => not found
libgmp.so.10 => /usr/lib/libgmp.so.10 (0xf7703000)
libdl.so.2 => /lib/libdl.so.2 (0xf76fe000)
libz.so.1 => /lib/libz.so.1 (0xf76e7000)
libm.so.6 => /lib/libm.so.6 (0xf76bb000)
libc.so.6 => /lib/libc.so.6 (0xf7536000)
/lib/ld-linux.so.2 (0xf776e000)
-------------------------
So something must be wrong when Hazel Russman said she had not installed gmp.
She surely could run gcc. Maybe there is a fallback when gmp is not there? I
have now to get a 64 bit Slackware and start testing...
@akh, thanks for the indications on how to use Slackware. It'll save much time.
