Summary: Problems building libgfortran from 7.2.0 on HP-UX
11.31/PA
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: bugzilla-gcc at thewrittenword dot com
Target Milestone: ---
I tried building gcc-7.2.0 on HP-UX 11.31/PA as follows:
$ gtar Jxf gcc-7.2.0.tar.xz
$ cd gcc-7.2.0
$ mkdir .obj
$ cd .obj
$ PATH=/opt/TWWfsw/gcc49/bin:$PATH ../configure \
SHELL=/opt/fsw/bash42/bin/bash --enable-nls --with-included-gettext \
--enable-shared --enable-languages=c,c++,fortran \
--with-gmp=/opt/TWWfsw/libgmp61 --with-isl=/opt/TWWfsw/libisl016 \
--with-mpc=/opt/TWWfsw/libmpc10 --with-mpfr=/opt/TWWfsw/libmpfr31 \
--with-gnu-as --with-as=/opt/TWWfsw/gcc7/hppa2.0-hp-hpux11.31/bin/as \
--with-local-prefix=/tmp/gcc7 --prefix=/tmp/gcc7
...
$ PATH=/opt/TWWfsw/gcc49/bin:$PATH \
ac_cv_prog_OBJCOPY="/opt/TWWfsw/gcc7/bin/gobjcopy" \
ac_cv_prog_OBJDUMP="/opt/TWWfsw/gcc7/bin/gobjdump" gmake
The build failed with the following:

I was able to build on HP-UX 11.23/PA.
