[OMPI users] Issues compiling HPL with OMPIv4.0.0

2019-04-03 Thread afernandez 
Hello,

I'm trying to compile HPL(v2.3) with OpenBLAS and OMPI. The compilation
succeeds when using the old OMPI (v1.10.8) but fails with OMPI v4.0.0 (I'm
still not using v4.0.1). The error is for an old subroutine that determines
machine-specific arithmetic constants:

Hi,

It looks like you are using the C++ wrapper compiler (mpiCC) instead of the C 
wrapper compiler (mpicc). Perhaps using mpicc instead of mpiCC will resolve 
your issue.

Best,

Sam

Indeed, you cannot use "try" as a variable name in C++ because it is a
https://en.cppreference.com/w/cpp/keyword.

As already suggested, use a C compiler, or you can replace "try" with
"xtry" or any other non-reserved word.

Re: [OMPI users] Issues compiling HPL with OMPIv4.0.0

2019-04-03 Thread afernandez 
Sam and Jeff,

Thank you for your answers. My first attempts actually used mpicc rather than 
mpiCC, switching to mpiCC was simply to check out if the problem persisted. I 
noticed that both mpicc and mpiCC are linked to the same file (opal_wrapper) 
and didn't bother switching it back. I'm not sure if the wrapper figures out 
what compiler you call because I was getting the same error message. Jeff is 
right pointing out that 'try' is reserved but the original file seems to be 
really old (think 1970). Apparently, the new compiler (shipped with OMPIv4) is 
more sensitive and beeps when the older didn't. 

Thanks again,

AFernandez

Re: [OMPI users] Issues compiling HPL with OMPIv4.0.0

2019-04-03 Thread Gilles Gouaillardet 

Do not get fooled by the symlinks to opal_wrapper !

opal_wrapper checks how it is invoked (e.g. check argv[0] in main()) and 
the behavior is different


if it is invoked as mpicc, mpiCC, mpifort and other


If the error persists with mpicc, you can manually extract the mpicc 
command line, and manually run it with the -showme parameter,


it will show you the full command line (and who knows, mpicc might 
invoke a C++ compiler after all, and that would be a config issue)



Cheers,


Gilles

Re: [OMPI users] Issues compiling HPL with OMPIv4.0.0

2019-04-03 Thread Nathan Hjelm via users 
Giles is correct. If mpicc is showing errors like those in your original email 
then it is not invoking a C compiler. C does not have any concept of try or 
catch. No modern C compiler will complain about a variable named “try” as it is 
not a reserved keyword in the C language.

Example:

foo.c:

int try = 0;

gcc --std=c11 -c foo.c

No error


g++ -c foo.c  
foo.c:3:5: error: expected unqualified-id
int try = 0;
^
1 error generated.
