build fails with newer automake/autoconf

[Michael-Hennecke]

When using autoconf/2.71 (and automake/1.16.5), the io500 build fails with errors like the following (autoconf/2.69 and automake/1.15.1 works fine):

configure.ac:13: warning: The macro `AC_CONFIG_HEADER' is obsolete.
configure.ac:13: You should run autoupdate.
./lib/autoconf/status.m4:719: AC_CONFIG_HEADER is expanded from...

Hi Michael, can you state exactly what you are doing? I get even different output using the exact same versions of tools.

I was running prepare.sh with Intel MPI. Just validated with a recent intel-toolkit/2025.0.1 including intel-mpi/2021.14.1:

Currently Loaded Modulefiles:
 1) admin/2.0     4) mpi_settings/2.0{mode=default}   7) intel-mpi/2021.14.1       10) intel-dnn/2025.0.1   13) intel-ipp/2022.0.0    16) intel-dpl/2022.7.1      19) autoconf/2.71
 2) tempdir/1.0   5) spack/24.1.1                     8) intel-mkl/2025.0.1        11) intel-itac/2022.4.0  14) intel-dal/2025.0.0    17) intel-dpct/2025.0.1     20) automake/1.16.5
 3) lrz/1.0       6) intel/2025.0.4                   9) intel-inspector/2024.1.0  12) intel-tbb/2022.0.0   15) intel-ippcp/2025.0.0  18) intel-toolkit/2025.0.1

As mentioned, using the older autoconf/automake works just fine.

Issue #79 seems to be the same problem, but we're on SLES 15 SP5:

> lsb_release -a
LSB Version:    n/a
Distributor ID: SUSE
Description:    SUSE Linux Enterprise Server 15 SP5
Release:        15.5

Is there a "known good" level of pkg-config?

Can you check the IOR version from: hpc/ior#518
