Hi Vladimir,
I tested the new build environment with some different configurations. From my
point of view it is a good solution. Very easy to use and to understand.
During the tests I found 2 little issues.
The first one hits the libibverbs. On ppc64 I built OFED-1.2 with following
command:
./install.pl --basic
Now the libibverbs is installed in /usr/lib64, but it is a 32bit libary:
systemx # file /usr/lib64/libibverbs.so.1.0.0
/usr/lib64/libibverbs.so.1.0.0: ELF 32-bit MSB shared object,
PowerPC or cisco 4500, version 1 (SYSV), not stripped
I would guess this is because you are trying to set the libdir and
compile mode flags yourselves? The rpmbuild environment has the ability
to set these things for you. For example, if you build using this
command on a ppc64 machine:
rpmbuild --ba --target=ppc libibverbs.spec
and inside the libibverbs.spec file simply use %{_libdir} and CFLAGS=
$RPM_OPT_FLAGS, then you get the right result.
Likewise, rpmbuild --ba --target=ppc64 libibverbs.spec *also* does the
right thing if you use %{_libdir} during configure and in %files and
also set CFLAGS=$RPM_OPT_FLAGS.
The only requirement for this to work is that you need to have installed
rpm-devel.ppc and rpm-devel.ppc64 (you get the correct macros from those
different packages).
At least this is how it works under RHEL. I would hope that SuSE is
sane in this regard too.
Trying to outsmart rpm instead of working with rpm on stuff like this is
a big part of why I want tarballs, not a distribution. It breaks in all
sorts of subtle ways.
So the following libaries like libmthca and libehca can not configure because
the libibverbs check fails. After I exported LDFLAGS and CFLAGS explicit with
-m64 option it was working fine.
The ppc64 RPM_OPT_FLAGS include -m64 because we know that -m32 is the
default setting in the compiler and you need it to force 64bit apps.
Hi Doug,
I tried what you said:
rpmbuild --ba --target=ppc --define "CFLAGS \$RPM_OPT_FLAGS" libibverbs.spec
But still got '--libdir=/usr/lib64' in the options to the configure during
rpmbuild.
In the libibverbs.spec:
%build
%configure
make %{?_smp_mflags}
Both rpm-devel.ppc and rpm-devel.ppc64 are installed.
What is wrong?
Regards,
Vladimir
