Dear Maintainers,
i am trying to install libmpich-dev:i386 with the following outcome:
root@ubuntu:~/MPICH_1604# apt-get install libmpich-dev:i386
...
The following packages have unmet dependencies:
libmpich-dev:i386 : Depends: gfortran:i386 but it is not going to be installed
Depends: g++:i386 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Please note, that gfortran:i386 and g++:i386 are neither required to use the
package, nor do they appear in the dependencies list.
Details on the package libmpich-dev, i put at the end of this mail.
I have the following packages installed (which allows me to build 32- and
64-bit applications using gcc, g++ and gfortran):
root@ubuntu:~/MPICH_1604# dpkg --get-selections | grep gfortran
gfortran install
gfortran-5 install
gfortran-5-doc install
gfortran-5-multilib install
gfortran-doc install
lib32gfortran-5-dev install
lib32gfortran3 install
libgfortran-5-dev:amd64 install
libgfortran3:amd64 install
libx32gfortran-5-dev install
libx32gfortran3 install
root@ubuntu:~/MPICH_1604# dpkg --get-selections | grep g++
g++ install
g++-5 install
Please mind that after a force install via:
root@ubuntu:~/MPICH_1604# apt-get download libmpich-dev:i386
and
root@ubuntu:~/MPICH_1604# dpkg --force-depends -i
libmpich-dev_3.2-6build1_i386.deb
all required files to compile and link are available.
mpich-packages installed now:
root@ubuntu:~/MPICH_1604# dpkg --get-selections | grep mpich
libmpich-dev:i386 install
libmpich12:i386 install
mpich:i386 install
mpich-doc install
and building mpich-applications works fine using either:
mpicc.mpich -o ../bin/hello hello.c -m32
or
gcc -o ../bin/hello hello.c -m32 -I/usr/include/mpich/
-L/usr/lib/i386-linux-gnu -lmpich
or
mpif90.mpich -cpp -o ../bin/hello hello.f90 -m32
I do not know whether the problem is on the apt side.
If apt translates the dependency gfortran to gfortran:i386 because the package
is :i386 then the bug is in apt.
Please let me know if should file a bug for apt.
Best Regards,
Dandy

Description-en: Development files for MPICH
MPICH is a high-performance and widely portable implementation of the
Message Passing Interface (MPI) standard (both MPI-1 and MPI-2). It
efficiently supports different computation and communication platforms
including commodity clusters, SMPs, massively parallel systems, and
high-speed networks.
.
This package includes the MPICH headers and static libraries, as well
as the compiler wrappers needed to build MPICH programs.
