Where is the libevent-2.1.12-stable-ompi.tar.gz file ?

[jde...@intec.unl.edu.ar]

Dear all,

I downloaded the openmpi-5.0.10.tar.gz package and I'm trying to build it using the
script given given in "Sec. 2.2. For problems building or installing Open MPI" of
https://docs.open-mpi.org/en/main/getting-help.html.

But it's failing me with the missing file /3rd-party/libevent-2.1.12-stable-ompi.tar.gz,
as follows:

*** Configuring Libevent
checking for libevent pkg-config name... libevent_core

Also I've also attached the config.log file.

Then, please, where can I download it? 

Thanks in advance.

Regards.
Jorge D'Elia.

Hello Jorge,

 

Could you check if /home/bigpack/openmpi-paq/openmpi-5.0.10/3rd-party

 

has libevent-2.1.12-stable-ompi.tar.gz present?

 

It should be there.  It may be possible something is wrong with the g(un)zip utilities on your system?

 

If the tarball is present in 3^rd-party why don’t you try running the following in the following in the 3^rd-party directory:

 

gunzip libevent-2.1.12-stable-ompi.tar.gz | tar xf –

 

and see what’s happens.

 

You may also want to check in the config.log in the top level directory of your unpacked Open MPI for “gzip” and see where the configury thinks your gzip command is located.

I followed the usual procedure, i.e. I downloaded the file
https://download.open-mpi.org/release/open-mpi/v5.0/openmpi-5.0.10.tar.gz
and configure it.

> has libevent-2.1.12-stable-ompi.tar.gz present?

However, there is no such file, i.e.

configure: Expanding ./3rd-party/libevent-2.1.12-stable-ompi.tar.gz in
3rd-party
./configure: line 60632:
/home/bigpack/openmpi-paq/openmpi-5.0.10/3rd-party/libevent-2.1.12-stable-ompi.tar.gz: No such file or

Ok, I'll check it just in case.

Ok but, again, there is not any file.

Ok.

Thanks again!

The libevent file is there in the 5.0.10 tarball:

$ wget https://download.open-mpi.org/release/open-mpi/v5.0/openmpi-5.0.10.tar.gz

…snipped… 

$ tar tf openmpi-5.0.10.tar.gz| grep libevent-2.1.12-stable-ompi.tar.gz

openmpi-5.0.10/3rd-party/libevent-2.1.12-stable-ompi.tar.gz

$

I think you might want to check how the original tarball was unzipped, and/or make sure that the backing store didn’t somehow exclude saving that file.

Dear Jeff Squyres,

Thank you so much for your suggestions. They helped me make some progress,
but I've gotten stuck again, this time with:

*** Configuring PMIx
configure: ===== configuring 3rd-party/openpmix =====
configure: WARNING: no configuration information is in 3rd-party/openpmix
configure: ===== done with 3rd-party/openpmix configure =====
configure: error: Could not find viable pmix build.

Please, where can I find a reliable PMIX source? Thanks in advance.

Regards.
Jorge D'Elia.

Just like libevent, OpenPMIx is also in that one tarball.  Most people can do the “quick start” in our docs: https://docs.open-mpi.org/en/v5.0.x/installing-open-mpi/quickstart.html#building-from-source

I.e., download, untar, run ./configure, run make, run make install.

If you’re doing something else, the instructions may be a bit different.  If you’re building from a git clone, for example, you’ll want to see the Developer’s guide: https://docs.open-mpi.org/en/v5.0.x/developers/index.html

[jde...@intec.unl.edu.ar]

Dear Jeff.

Many thanks for your suggestions. In short:

1) The problem was (and still is present) with the source code of alternative 1
(https://download.open-mpi.org/release/open-mpi/v5.0/openmpi-5.0.10.tar.gz),
because that file does not contain all source codes in /3rd-party.

2) But with the source code of alternative 2
(https://download.open-mpi.org/release/open-mpi/v5.0/openmpi-5.0.10.tar.bz2),
everything returned to the normal way (sources, configuration, building, and installation).

Perhaps, the construction of the *.tar.gz file available in the repository should be reviewed.

Regards.
Jorge D'Elia

The two files are constructed exactly the same; the only difference is in how they are compressed in just about the last step (during the Automake-generated “make dist” step).

I am unable to replicate your problem.  Could you send all the logs of how you download and expand the .gz tarball, and all the logs described here: https://docs.open-mpi.org/en/v5.0.x/getting-help.html#for-problems-building-or-installing-open-mpi

Specifically, when I download, examine, and build the 5.0.10 gz and bz2 tarballs, they function identically for me.  For example, I wrote this short comparison script:

———

$ cat test.sh 

#!/bin/sh

TARBALL=openmpi-5.0.10.tar

URL_STEM=https://download.open-mpi.org/release/open-mpi/v5.0

# Hand-copied from https://www.open-mpi.org/software/ompi/v5.0/

UPSTREAM_SHA256_BZ2=0acecc4fc218e5debdbcb8a41d182c6b0f1d29393015ed763b2a91d5d7374cc6

UPSTREAM_SHA256_GZ=5692cc80554a7117c99eaa725d35100edd8bbf73423a5e265ff867979192df7d

echo "Downloading bz2"

rm -f $TARBALL.bz2

wget -q $URL_STEM/$TARBALL.bz2

echo "Downloading gz"

rm -f $TARBALL.gz

wget -q $URL_STEM/$TARBALL.gz

echo "Computing sha256 bz2"

DL_SHA256_BZ2=$(sha256sum $TARBALL.bz2 | awk '{print $1}')

echo "Computing sha256 gz"

DL_SHA256_GZ=$(sha256sum $TARBALL.gz | awk '{print $1}')

if [[ $UPSTREAM_SHA256_BZ2 != $DL_SHA256_BZ2 ]]; then

    echo "bz2 SHA256's don't match!"

    echo "- upstream:   $UPSTREAM_SHA256_BZ2"

    echo "- downloaded: $DL_SHA256_BZ2"

else

    echo "bz2: good download"

fi

if [[ $UPSTREAM_SHA256_GZ != $DL_SHA256_GZ ]]; then

    echo "gz SHA256's don't match!"

    echo "- upstream:   $UPSTREAM_SHA256_GZ"

    echo "- downloaded: $DL_SHA256_GZ"

else

    echo "gz: good download"

fi

DIR=3rd-party/openpmix/

echo "Number of files in $DIR in bz2"

tar tf $TARBALL.bz2 | grep $DIR | wc -l

echo "Number of files in $DIR in gz"

tar tf $TARBALL.gz | grep $DIR | wc -l

———

And when I run it:

$ ./test.sh

Downloading bz2

Downloading gz

Computing sha256 bz2

Computing sha256 gz

bz2: good download

gz: good download

Number of files in 3rd-party/openpmix/ in bz2

    1291

Number of files in 3rd-party/openpmix/ in gz

    1291

Same number of files in 3rd-party/openpmix in both tarballs.  And both tarballs expand and build properly for me.

Dear Jeff,

You can forget about my difficulties.

Yesterday I started again from scratch and, this time, the entire compilation is
(almost) normal. The almost is because I had to edit the file:

emacs ${SOURCE}/ompi/mca/part/persist/part_persist.h,

where I had to change the definition of mca_part_persist_start (around line 484) and
comment out the __always_inline__ directive, due to a persistent error message:

inlined from ‘mca_part_persist_start’ at ../../../../../ompi/mca/part/persist/part_persist.h:500:23:
../../../../../ompi/mca/part/persist/part_persist.h:484:1: error: inlining failed in call to ‘always_inline’ ‘mca_part_persist_start’: recursive inlining
  484 | mca_part_persist_start(size_t count, ompi_request_t** requests)

Previously, I tried increasing the value of the max-inline-insns-single parameter,
but the error persisted. 

I've attached two files (config.log and ompi_info_param.log).

Many thanks for your time, and my apologies for bothering you.

Regards,
Jorge D'Elia.

I think the part_persist.h issue just came up in a GitHub issue: https://github.com/open-mpi/ompi/issues/13847
