running HYPHY on ppc64 GNU/Linux
Jun 21st, 2005 at 5:14am  
Hi all,

I compiled HYPHY on a OpenPower 720 ppc64 GNU/Linux, but I'm having a problem when running it:

./HYPHYMP
options 1->1

Error:
Operation: < is not defined.

with options 2->1:
Error:
Operation: MAccess is not defined.

It seems there is a problem when asking for files.

Any guess?

    Albert.

I have run into a similar problem with IBM's xLC. It is due to the fact that I made a (non-portable) assumption that 'char' types in C are signed by default, while on some systems they are unsigned by default (e.g. PPC systems).

Your compiler should have a command line option to force the 'char' type to be signed. In gcc, the option is -fsigned-char. If you turn that on and recompile, things should improve.

Cheers,
Sergei

yep, that did the trick:

COMPILER_FLAGS=" -w -c -O3 -D__HYPHY_NO_CURL__ -fsigned-char -fpermissive -I`pwd`/Source -I`pw\d`/Source/SQLite ";

Thanks again,

    Albert.

Dear Albert,

I will add the flag to the standard build script. Thanks for bringing this to my attention.

Cheers,
Sergei
