Sorry about the confusion. btw, i am not sure how to respond to responses in
this mailing list.
I have both the problem of knowing which .h filese need to be
translated/included AND which LAM libraries to include. I though that the
wrapper that was listed in this posting:
http://www.lam-mpi.org/MailArchives/lam/msg01611.php
was pretty much the translation of whatever .h files needed to be
translated.
I copied the mpi unit code from the above posting and modified it a little
it so that kylix would accept it.
- had to change the directive used to link libraries from $LINKLIB to $LINK
or $L
- had to comment out all the "external name 'lam_mpi_byte';" sections from
the var section....
My problem is the library section. Mine looks like this :
{$L mpi++.o}
{$L mpio.o}
{$L mpi.o}
{$L tstdio.o}
{$L trillium.o}
{$L args.o}
{$L t.o}
I had to add the ".o" because Kylix expects them (else for some weird reason
it thinks the libraries are .obj files). Where are these .o files supposed
to be? I know that I can find some by modifying the makefile so that the .o
files are not deleted. i did this and copied the ones i needed and could
find to the directory where my project is but i still got errors in
compiling my project. These are what the errors look like:
[Error] mpiwrapper2.pas(215): Unsatisfied forward or external declaration:
'MPI_Init'
[Error] mpiwrapper2.pas(216): Unsatisfied forward or external declaration:
'MPI_Comm_size'
[Error] mpiwrapper2.pas(217): Unsatisfied forward or external declaration:
'MPI_Comm_rank'
[Error] mpiwrapper2.pas(218): Unsatisfied forward or external declaration:
'MPI_Send'
[Error] mpiwrapper2.pas(219): Unsatisfied forward or external declaration:
'MPI_Recv'
[Error] mpiwrapper2.pas(219): Unsatisfied forward or external declaration:
'MPI_Finalize'
I think they mean that I am not including the libraries i need to link to
I ran mpicc -showme and got the libraries that are linked to by mpicc. but,
these are .a files. kylix cant link to .a files as far as i know. is there
any way to convert .a files to .o files? i was told that .a files are just a
compilation of .o files...
A lot of words. my problem is basically, where are the .o files that the mpi
unit code in the posting above links to?

I'm not sure what you mean -- I think you mean that you need to know the
LAM libraries to link to, but you might also mean which .h files need to
be translated/included (you used "libraries" and "included" in the same
sentence, and it's difficult to parse that properly...).
If you mean which libraries to link to, simply run "mpicc -showme" and it
should show you the libraries and the correct order to use.
Note that this will get more complicated in LAM/MPI 7.0 because the list
of libraries will be variable (depending on how LAM/MPI was configured,
etc.).
