Bug ID: 86553
Summary: libstdc++-v3 build failure on AIX 5.3
Product: gcc
Version: 8.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: bugzilla-gcc at thewrittenword dot com
Target Milestone: ---
I tried building gcc-8.1.0 on AIX 5.3 as follows:
$ gtar Jxf gcc-8.1.0.tar.xz
$ cd gcc-8.1.0
$ mkdir .obj
$ cd .obj
$ PATH=/opt/TWWfsw/gcc47/bin:$PATH LDR_CNTRL=MAXDATA=0x70000000 \
../configure SHELL=/opt/fsw/bash42/bin/bash LDFLAGS="-Wl,-brtl \
-Wl,-blibpath:/opt/TWWfsw/libisl016/lib:/opt/TWWfsw/libgmp61/lib:\
/opt/TWWfsw/libmpc10/lib:/opt/TWWfsw/libmpfr31/lib:/usr/lib" \
--enable-nls --with-included-gettext --enable-shared \
--enable-threads --enable-languages=c,c++ \
--with-gmp=/opt/TWWfsw/libgmp61 --with-isl=/opt/TWWfsw/libisl016 \
--with-mpc=/opt/TWWfsw/libmpc10 --with-mpfr=/opt/TWWfsw/libmpfr31 \
--with-local-prefix=/tmp/gcc8 --prefix=/tmp/gcc8
$ PATH=/opt/TWWfsw/gcc47/bin:$PATH LDR_CNTRL=MAXDATA=0x70000000 gmake
The build failed with the following:
