dealii 9.3.0 make install fails at "Generating mpi.inst" with Invalid instantiation list: missing 'for'

[vachanpo...@gmail.com]

Dear all,

I am installing a newer version of dealii on our cluster (cray xc50) and make install fails at "Generating mpi.inst" with the statement

Invalid instantiation list: missing 'for'

make[2]: *** [source/base/CMakeFiles/obj_base_inst.dir/build.make:135: source/base/mpi.inst] Error 1

make[1]: *** [CMakeFiles/Makefile2:2408: source/base/CMakeFiles/obj_base_inst.dir/all] Error 2

make: *** [Makefile:130: all] Error 2

I am attaching the output of the configuration. The options used for configuration are as follows.

cmake -DCMAKE_INSTALL_PREFIX=~/bin/dealii-9.3.0/ \

        -DWITH_64BIT_INDICES=ON \

-DCMAKE_PREFIX_PATH=/opt/cray/pe/lib64 \

-DWITH_MPI=ON \

                -DCMAKE_CXX_COMPILER=$(which CC) \

                -DCMAKE_C_COMPILER=$(which cc) \

-DWITH_P4EST=ON -DP4EST_DIR=~/bin/p4est-2.2/ \

        -DCMAKE_SYSTEM_NAME=CrayLinuxEnvironment \

~/source/dealii-9.3.0

Earlier, with some fixes, I was able to install 9.1.1. I am unable to ascertain the source of this. Any help would be greatly appreciated.

Thanking in anticipation

I had noticed that this make error would occur if the file being expanded doesn't have a prefix 'for'. The following snippet is from line 453- of dealii/cmake/scripts/expand_instantiations.cc

if (!has_prefix(whole_file, "for"))

{

std::cerr << "Invalid instantiation list: missing 'for'" << std::endl;

std::exit(1);

}

Now, I also noticed that dealii/source/base/mpi.inst.in has all the template function instantiations enclosed within #ifndef DOXYGEN ... #endif. And in fact, this is the only instantiation file which does so. I thought this could be the issue and commented these two statements (#ifndef and #endif). Then the installation went past this point (not complete yet though).

I have two questions based on what I saw so far.

1. Why are the mpi function instantiations to be declared only when doxygen is not configured.
2. If I understand correctly, the function expand_instantiations.cc also has the following code snippet to ignore any preprocessor macros (line 445). Why is this not working when the line #ifndef DOXYGEN is added to mpi.inst.in?

// output preprocessor defines as is:

if (has_prefix(whole_file, "#"))

{

std::cout << get_substring_with_delim(whole_file, "\n") << '\n';

skip_space(whole_file);

continue;

}

Thanks,

After some time, the installation again halts with the same error this time with the file source/sundials/n_vector.inst.in.

Meanwhile, I had also noticed that there are indeed files with preprocessor commands which got through the installation. For example, source/multigrid/mg_level_global_transfer.inst.in had no issue. I went through some such files and noticed that while these files have preprocessor macros inside the "for" loop, source/sundials/n_vector.inst.in and source/base/mpi.inst.in have them outside the loop. I am guessing that this specific ordering is causing an error.

I am puzzled as to why such a thing is happening. I had installed 9.3.0 on two computers before this and had no issue. It would be great if anyone can help me with a hack to fix this.

Thanks,
