[Rcppoctave-user] unable to install RcppOctave (Octave 3.8 Linux)

[kam kammon]

Hi,

Still doesn't work but with a different error which doesn't seem to involve mpi this time. It says it is an octave error but I have no idea what it may be.

Hi,

can you please try again (from branch 'develop'). I have pushed a fix that should solve the issue.
The MPI flags were stored in CPPFLAGS, which I now append to INCFLAGS


mkoctfile -p INCFLAGS
mkoctfile -p CPPFLAGS

Please flag this thread as SOLVED if this fixes the issue.
Thanks.

Bests,
Renaud

One more thought: have you tried installing after doing

export  CPPFLAGS="-I/usr/include/mpi -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX"

?

Actually, the flags are most likely to be found in mkoctfile config.
Currently I use the flags returned by:

mkoctfile -p INCFLAGS

Might be easier if you could look if those effectively appear in this variable or any other (do mkoctfile --help to list all variables). They have to come from somewhere...



Thanks.

Good.
The MPI issue seems to be due to some compilation flags not being carried over when compiling RcppOctave library. 



The MPI specific flags "-I/usr/include/mpi -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX" are correctly used when compiling the Octave modules, so these flags should be available from octave-config.

Will look into it later.
Thanks.

Bests,
Renaud
