Summary: boehm-gc build problem with uclibc
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: boehm-gc
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dougmenc...@gmail.com
I'm trying to get GCC with GCJ (and related libs). The ./configure options I
use are the following:
--------------------------------------------------------------------------------
../"${SOURCE_DIR}"/configure --prefix=/usr --sysconfdir=/etc
--mandir=/usr/share/man \
--enable-languages=c,c++,fortran,java --with-cpu=default32 \
--with-system-zlib --enable-threads=posix \
--disable-nls --disable-werror --disable-multilib --disable-libssp \
--disable-__cxa_atexit --disable-checking --enable-shared \
--enable-libgcj --enable-libgcj-multifile --enable-interpreter
--disable-libjava-multilib
--------------------------------------------------------------------------------
At stage 3, make fails with the following error:
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Diving into that problem, I figured out that boehm-gc sources (actually,
./boehm-gc/include/gc.h) checks if __GLIBC__ is defined, and then trying to
include execinfo.h.
Back in 2006, Solar from Gentoo team already wrote a patch to fix that issue:
http://bugs.gentoo.org/121463 (the patch itself:
http://bugs.gentoo.org/attachment.cgi?id=80702 ). With this patch, boehm-gc
builds without errors.
