Port libgcc's configury for *-*-gnu*
Hello!
Here is a patch to port libgcc's configury for *-*gnu*.
Hurd people: I guess we'll want t-tls, correct? (As we do support
__thread.)
Debian BSD people: please (a) check again that I didn't break anything
for you, (b) think about whether you want t-tls as well.
Both parties: do we also want changes installed for libgcc's configure.ac
for the floating point stuff that currently only matches against *linux*?

Re: build system: gcc_cv_libc_provides_ssp and NATIVE_SYSTEM_HEADER_DIR
Thomas Schwinge dixit: First, the check for gcc_cv_libc_provides_ssp is not complete, as has already pointed out (with patches!) before, but is still not fixed on trunk. Let me revisit that: in configure.ac it is being checked for ``case $target in *-*-linux*)'' which should rather match ``*-*-linux* | *-*-*-gnu* | *-*-gnu*'' to catch all GNU/Linux, GNU/Hurd, GNU/k*BSD systems. FWIW, DragonFly, MirBSD and OpenBSD (at least) also provide the SSP functions in their respective C libraries. bye, //mirabilos -- Sometimes they [people] care too much: pretty printers [and syntax highligh- ting, d.A.] mechanically produce pretty output that accentuates irrelevant detail in the program, which is as sensible as putting all the prepositions in English text in bold font. -- Rob Pike in Notes on Programming in C -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

build system: gcc_cv_libc_provides_ssp and NATIVE_SYSTEM_HEADER_DIR
Hello!
First, the check for gcc_cv_libc_provides_ssp is not complete, as has
already pointed out (with patches!) before, but is still not fixed on
trunk. Let me revisit that: in configure.ac it is being checked for
``case $target in *-*-linux*)'' which should rather match ``*-*-linux*
| *-*-*-gnu* | *-*-gnu*'' to catch all GNU/Linux, GNU/Hurd, GNU/k*BSD
systems. (This is being patched in the Debian GCC package for some time
already.)
But then, second, there still is a problem in that test: later on glibc's
features.h is being grepped, expecting it to reside at a place like
SYS_ROOT/usr/include/features.h. However, this needn't be true:
gcc/doc/fragments.texi
@item NATIVE_SYSTEM_HEADER_DIR
If the default location for system headers is not @file{/usr/include},
you must set this to the directory containing the headers. This value
should match the value of the @code{SYSTEM_INCLUDE_DIR} macro.
Unfortunately, NATIVE_SYSTEM_HEADER_DIR is a Makefile variable (see
gcc/config/t-gnu). It is being used only in three places:
gcc/config/t-gnu, gcc/config/t-gnu and gcc/config/i386/t-mingw32. What
do you suggest? Make that definition a shell variable and move it to
gcc/config.gcc?
Regards,
Thomas

[EMAIL PROTECTED]: Bug#497165: amiga-fdisk-cross is not being built on any architecture other than i386]
Hi, could the buildd admins please enable building for amiga-fdisk and upload the resulting packages (powerpc has been built, but it seems it was never uploaded). thanks, Christian - Forwarded message from Martin Guy [EMAIL PROTECTED] - Subject: Bug#497165: amiga-fdisk-cross is not being built on any architecture other than i386 Not a bug in amiga-fdisk itself, but a Debian buildd issue that needs sorting On 16 Jan 2008, armel was added to the architecture list for amiga-fdisk-cross (bug #461081) but, despite being enabled for 12 architectures, the package has not been built for anything but i386. I am guessing this is due to being included in the various buildd admins' Not-For-Us lists - can you poke them?

First off, debian-ports is not the right contact address for buildd admins, there is no guarantee the buildd admins of a particular port are subscribed, AFAIK. Second, you need to get amiga-fdisk removed from packages-arch-specific to have it built by the buildds, see http://cvs.debian.org/srcdep/Packages-arch-specific?root=dakview=markup and the contact addresses at the top of that file. cheers, Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

[PATCH] GNU/Hurd target configuration
Hello!
Here is a patch to bring the target configuration for GNU/Hurd up to a
level so that GCC trunk is buildable for GNU/Hurd again (together with
other patches that are already available or are still to be written; see
my other posts). This GCC does even ;-) produce working binaries.
Please discuss with the goal to have this eventually committed to the GCC
trunk.
No ChangeLog yet.
