Compilation problem "error: ‘MPI_part1d_forwardmodel’ was not declared in this scope"

[volkerrath]

Hi,
I'm compiling under ubuntu 20.04 with gcc 9.4, and openmpi 4.0.3. However I get the error:
../src/rjmcmcmt.cpp: In member function ‘int cRjMcMCMT::run()’:
../src/rjmcmcmt.cpp:319:30: error: ‘MPI_part1d_forwardmodel’ was not declared in this scope; did you mean ‘part1d_forwardmodel’?
319 | resultset1dfm_t* results = MPI_part1d_forwardmodel(burninsamples,
| ^~~~~~~~~~~~~~~~~~~~~~~
| part1d_forwardmodel
make: *** [rjmcmcmt.make:24: ../src/rjmcmcmt.o] Error 1
Can you help?

Hello Volker I am fairly certain the problem is that when you have compiled the underlying rj-MCMC library from (http://www.iearth.org.au/codes/rj-MCMC) you have not compiled it with MPI enabled. On the Win10 emulator version of Ubuntu 20.04 I do the following

> mpicc –showme (to see where the openmpi include and lib paths are, which gives the following)

gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include -pthread -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi Note that these are then used in the build script below for the (--with-openmpi --with-openmpi-include-path --with-openmpi-lib-path) #!/bin/bash ### RJMCMC-1.0.11 source code dir is: /mnt/c/Users/rossc/work/code/third_party/iearth/RJMCMC-1.0.11 ### RJMCMC-1.0.11 install dir is: /mnt/c/Users/rossc/work/code/third_party/iearth/RJMCMC-1.0.11/ubuntu-win10/gnu export LIBRJMCMC_ROOT=/mnt/c/Users/rossc/work/code/third_party/iearth/RJMCMC-1.0.11/ubuntu-win10/gnu ./configure --prefix=$LIBRJMCMC_ROOT --with-openmpi --with-openmpi-include-path=/usr/lib/x86_64-linux-gnu/openmpi/include --with-openmpi-lib-path=/usr/lib/x86_64-linux-gnu/openmpi/lib make clean make make install If your openmpi is set up nicely you may not need the --with-openmpi-include-path or --with-openmpi-lib-path but definitely use the --with-openmpi If that’s successful you should then be able to go back and compile rjmcmcmt I hope that helps.
