WITHOUT_GCC for build target / system without base gcc (9RC1)
Hello. When one can expect being able to have system without base gcc installed? Since I enabled clang, and I'm using gcc46 for ports, having base gcc is largely pointless for me, but couldn't build system with clang only, because of: === usr.bin/xlint/llib (all) lint -cghapbx -Cposix /usr/src/usr.bin/xlint/llib/llib-lposix llib-lposix: lint: cannot exec /usr/obj/usr/src/tmp/usr/bin/cc: No such file or directory *** Error code 1 best regards, - Jakub Lach PS. If I'm doing something retarded, feel free to point out. I'm just feeling that 3 compilers on one system is a bit much, and most ports are developed with newest gcc in mind, while for FreeBSD clang is obviously way to go. FWIW, right now I would need base gcc only for compiling libreoffice, and I hope it will change sometime in future. -- View this message in context: http://freebsd.1045724.n5.nabble.com/WITHOUT-GCC-for-build-target-system-without-base-gcc-9RC1-tp4951986p4951986.html Sent from the freebsd-current mailing list archive at Nabble.com. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

There's quite some work to be done. The trickiest part is to get rid of
GNU libstdc++, which is sort of a symbiote with gcc.
Also, there are still some programs that hardcode ${CC}, and ignore any
environment-supplied value.

You should use clang for ports. :) But seriously, building ports which
have not explicitly been marked as being gcc 4.5 or 4.6 compatible is
taking a chance. It might work, or break in various interesting ways.
That said, many problems that manifest in ports when you build them with
clang, also pop up with newer versions of gcc, simply because both are
more strict with regard to sloppy coding practices.
but couldn't build system with clang only,
because of:
=== usr.bin/xlint/llib (all)
lint -cghapbx -Cposix /usr/src/usr.bin/xlint/llib/llib-lposix
llib-lposix:
lint: cannot exec /usr/obj/usr/src/tmp/usr/bin/cc: No such file or directory

Yes, this is one of the programs that hardcodedly calls 'cc', and
ignores environment values. I simply haven't got to fixing this yet,
but I plan on doing so soon.

As I said, many ports compile fine with clang, so you could get by just
with the compiler in base. On my systems, everything is clang-compiled,
including all ports, but I am using just a subset of the available ones,
of course.
There are even people that would like to remove all compilers from the
base system, and move them to an external package, so you can freely
switch to whatever toolchain has your fancy. But that will take some
time to materialize... :)
FWIW, right now I would need base gcc only for compiling
libreoffice, and I hope it will change sometime in future.
I have no idea what the issues are with libreoffice, so I can't help you
there, sorry.

Hi, thanks for reply. But seriously, building ports which have not explicitly been marked as being gcc 4.5 or 4.6 compatible is taking a chance. It might work, or break in various interesting ways. Yes, I know. I'm just using small subset of ports as well. Will probably try clang for ports too, when feeling suitably adventurous :) While totally unscientific, clang 3.0 (-O2 -march=native) surprised me with getting more MIPS from p7zip than gcc46. Clang built kernel is smaller here too. Libreoffice is not problem per se, considering it's nature, I'm happy it's working at all for me. best regards, - Jakub Lach -- View this message in context: http://freebsd.1045724.n5.nabble.com/WITHOUT-GCC-for-build-target-system-without-base-gcc-9RC1-tp4951986p4952372.html Sent from the freebsd-current mailing list archive at Nabble.com. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
