Thu 12 Jan 2012 09:07:39 PM UTC, comment #7: For gcc64 (OpenBSD/sparc64) I recommend upgrading to a more recent OpenBSD version first. Then gcc 4.6 may be buildable...	Matthieu Herrb <mattthieu>
Tue 29 Nov 2011 06:32:12 PM UTC, comment #6: IIRC on gcc40 I used a recent version of binutils for bootstrapping. Thanks to the people, now we have gcc110, where such tricks are no longer needed. :) mik	Anonymous
Sat 05 Nov 2011 10:18:37 PM UTC, comment #5: I still did not manage to find out the right configure options to build GCC 4.6.2 on gcc40. I do not know why I obtain a "lazy binding failed". I have to investigate further, especially when https://gna.org/support/?2812 mentions that a 4.6 version has successfully been built in /home/mik/misc/gcc-4.6/bin (yet, even with the configure flags of that version, I have issues -- strange, I must be doing something wrong).

Mon 15 Aug 2011 07:54:20 PM UTC, comment #3: > A while ago the following did work: > CC="gcc -m64" Marvellous! That was enough to succeed in building GCC on gcc40. Thanks, Laurent. However, I still do not manage to build GCC on gcc64. I tried "gcc -m64" as well as disabling multilib, nls and using the flags you suggest. Still unsuccessfully. Maybe GMP, MPFR or MPC are not well built. I obtain the following error: /home/iulius/autobuild/src/gcc-core-4.6.1/host-sparc64-unknown-openbsd4.6/gcc/cc1:/home/iulius/autobuild/src/gcc-core-4.6 .1/host-sparc64-unknown-openbsd4.6/gcc/cc1: undefined symbol '' lazy binding failed! cc1: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. As I am still puzzled about the reason of this error, I opened as suggested a bug report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50064 If I have any news, I will obviously report on this ticket.

Sat 06 Aug 2011 12:46:47 PM UTC, original submission: Hi, I do not manage to build GCC 4.6.1 on gcc40 and gcc64. Is there a trick to build current versions of GCC on these systems? (If yes, could it be added to the main page of the project?) gcc40 (powerpc64) ----------------- I obtain: /home/iulius/autobuild/src/gcc-core-4.6.1/host-powerpc64-unknown-linux-gnu/gcc/../.././gcc/vecir.h:28: relocation truncated to fit: R_PPC_REL24 against symbol `memcpy@@GLIBC_2.0' defined in .glink section in /usr/lib/gcc/powerpc-linux-gnu/4.3.2/../../../../lib/crt1.o c-lang.o: In function `VEC_tree_base_quick_push': /home/iulius/autobuild/src/gcc-core-4.6.1/host-powerpc64-unknown-linux-gnu/gcc/../.././gcc/vecir.h:28: additional relocation overflows omitted from the output collect2: ld returned 1 exit status I tried with the installed system binutils, and with latest binutils. I also tried with legacy GMP 4.2.4, MPFR 2.3.2 and MPC 0.8.1, even the -64 ones in /opt/cfarm, as well as current versions, but without success. gcc64 (sparc64) --------------- checking for sparc64-unknown-openbsd4.6-gcc... /home/iulius/autobuild/src/gcc-core-4.6.1/host-sparc64-unknown-openbsd4.6/gcc/xgcc -B/home/iulius/autobuild/src/gcc-core-4.6.1/host-sparc64-unknown-openbsd4.6/gcc/ -B/home/iulius/autobuild/bin/gcc-core-4.6.1/sparc64-unknown-openbsd4.6/bin/ -B/home/iulius/autobuild/bin/gcc-core-4.6.1/sparc64-unknown-openbsd4.6/lib/ -isystem /home/iulius/autobuild/bin/gcc-core-4.6.1/sparc64-unknown-openbsd4.6/include -isystem /home/iulius/autobuild/bin/gcc-core-4.6.1/sparc64-unknown-openbsd4.6/sys-include checking for suffix of object files... configure: error: in `/home/iulius/autobuild/src/gcc-core-4.6.1/sparc64-unknown-openbsd4.6/libgcc': configure: error: cannot compute suffix of object files: cannot compile I am puzzled by this error. Are a few libraries missing in gcc64? Also, I do not see any /opt/cfarm directory in gcc64. (Is it intended?) I therefore could not try any other available packages. Julien	Julien ÉLIE <iulius>
