Public bug reported:
Binary package hint: openmpi-bin
On Ubuntu 7.04, mpicc from the openmpi-bin package works and produces
the normal lines to compile a C program that uses MPI:
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=7.04
DISTRIB_CODENAME=feisty
DISTRIB_DESCRIPTION="Ubuntu 7.04"
$ dpkg -l | grep openmpi
ii openmpi-bin 1.1-2.3
high performance message passing library
ii openmpi-common 1.1-2.3
high performance message passing library
ii openmpi-dev 1.1-2.3
high performance message passing library
ii openmpi-libs0 1.1-2.3
high performance message passing library
$ mpicc -showme
gcc -I/usr/include/openmpi -pthread -lmpi -lorte -lopal -ldl
-Wl,--export-dynamic -lnsl -lutil -lm -ldl
$ mpicc -showme:compile
-I/usr/include/openmpi -pthread
$ mpicc -showme:link
-pthread -lmpi -lorte -lopal -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
$ ls hello*
hello.c
$ mpicc -Wall -O2 hello.c -o hello
$ ls hello*
hello hello.c
However on Ubuntu 7.10 RC, the mpicc command produces no output and will
not build a MPI C program:
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=7.10
DISTRIB_CODENAME=gutsy
DISTRIB_DESCRIPTION="Ubuntu 7.10"
$ dpkg -l | grep openmpi
ii openmpi-bin 1.1-2.5
high performance message passing library
ii openmpi-common 1.1-2.5
high performance message passing library
ii openmpi-dev 1.1-2.5
high performance message passing library
ii openmpi-libs0 1.1-2.5
high performance message passing library
$ mpicc -showme
$ mpicc -showme:compile
$ mpicc -showme:link
$ ls hello*
hello.c
$ mpicc -Wall -O2 hello.c -o hello
$ ls hello*
hello.c
