Public bug reported: I have been trying to install and run coarray libraries for gfortran. Every instruction set I can find on the interwebs gives Ubuntu 18.04 instructions. So far, I have run into a series of errors, using 20.04 and it seems I am not alone. Here is where I am at:
I was looking to run coarrays in gfortran. I was following instructions et al that directed me to download open-coarrays-bin using apt. I get an error message saying that apt is unable to find the package. I found another post mentioning this error in 20.04, at https://github.com/sourceryinstitute/OpenCoarrays/issues/702. So, I was informed of a workaround, with the commands: ``` cd ~/Downloads wget http://archive.ubuntu.com/ubuntu/pool/universe/h/hwloc/libhwloc5_1.11.9-1_amd64.deb wget http://archive.ubuntu.com/ubuntu/pool/universe/o/openmpi/libopenmpi2_2.1.1-8_amd64.deb wget http://archive.ubuntu.com/ubuntu/pool/universe/o/open-coarrays/libcaf-mpi2_2.0.0~rc1-2_amd64.deb wget http://archive.ubuntu.com/ubuntu/pool/universe/o/open-coarrays/open-coarrays-bin_2.0.0~rc1-2_amd64.deb sudo apt-get install ./libhwloc5_1.11.9-1_amd64.deb ./libopenmpi2_2.1.1-8_amd64.deb ./libcaf-mpi2_2.0.0~rc1-2_amd64.deb ./open-coarrays-bin_2.0.0~rc1-2_amd64.deb ``` And so, now, checking, the binary package is installed, but when I go to compile a test script: ``` gfortran -fcoarray=lib test_coarray.f95 -o testcoarray ``` I get the error: ``` /usr/bin/ld: /tmp/cctOU7Q5.o: in function `MAIN__': test_coarray.f95:(.text+0x67): undefined reference to `_gfortran_caf_this_image' /usr/bin/ld: test_coarray.f95:(.text+0xaf): undefined reference to `_gfortran_caf_num_images' /usr/bin/ld: /tmp/cctOU7Q5.o: in function `main': test_coarray.f95:(.text+0x11c): undefined reference to `_gfortran_caf_init' /usr/bin/ld: test_coarray.f95:(.text+0x148): undefined reference to `_gfortran_caf_finalize' collect2: error: ld returned 1 exit status ``` using caf directly: ``` caf test_coarray.f95 -o testcoarray ``` I get the error: ``` gfortran: error: /usr/lib/x86_64-linux-gnu/libcaf_mpi.a: No such file or directory Error: comand: `/usr/bin/mpifort -I/usr/include/OpenCoarrays-2.0.0-rc1_GNU-7.3.0 -fcoarray=lib test_coarray.f95 -o testcoarray /usr/lib/x86_64-linux-gnu/libcaf_mpi.a` failed to compile. ``` Okay, so I do some digging and it seems that the libcaf_mpi.a file does not exist. Running: ``` ls /usr/lib/x86_64-linux-gnu | grep libcaf ``` I get: ``` libcaf_mpich.a libcaf_mpich.so libcaf_mpich.so.3 libcaf_mpi.so.2 libcaf_openmpi.a libcaf_openmpi.so libcaf_openmpi.so.3 ``` I saw somewhere in my searching that someone modified the /usr/bin/caf file, changing the line: ``` caf_libs=(lib/x86_64-linux-gnu/libcaf_mpi.a) # e.g. "libcaf_mpi" "libcaf_extensions", ``` to: ``` caf_libs=(lib/x86_64-linux-gnu/libcaf_mpi.so.2) # e.g. "libcaf_mpi" "libcaf_extensions", ``` So, now, I try to compile the code, but I get the message: ``` f951: Warning: Nonexistent include directory ‘/usr/include/OpenCoarrays-2.0.0-rc1_GNU-7.3.0’ [-Wmissing-include-dirs] /usr/bin/ld: warning: libmpi_mpifh.so.20, needed by /usr/lib/x86_64-linux-gnu/libcaf_mpi.so.2, may conflict with libmpi_mpifh.so.40 /usr/bin/ld: warning: libgfortran.so.4, needed by /usr/lib/x86_64-linux-gnu/libcaf_mpi.so.2, may conflict with libgfortran.so.5 ``` So, it seems there is some unmet dependencies in the repositories, but I am not sure. I have, here, reached the end of both my expertise and, it seems, the internet trail of this bug. It would seem that this all works in Ubuntu 18.04, but I have not tested it myself, so I cannot be sure. I thank you for reading this far and really do hope that I haven't overloaded you with too much detail. Coarrays really is necessary for my work and your help here will be greatly appreciated. Please let me know if there is any more information needed and it will be provided posthaste.
