ABINIT Discussion Forums

Hi,
I want to install abinit6.4.3 in IBM blue gene. I tried ./configure which gave the following error:

What might be the problem? Is there any other way to install abinit in blue gene?

Thanks

Hello Swasti,

It looks like configure complains when trying to link a simple fortran code. Have a look on config.log for the (last) offending test and it should give you a clue for a corrective action - like adding FCFLAGS ... Sorry I cannot be more specific without a copy of the file.

Abinit is routinely (i.e. several times a day) tested with xlf 9 and 12 (and POE). You'll find the corresponding environment in doc/config/build-examples/bb_power6-xlf_ibm6_serial.ac and bb_power6-xlf_ibm6.ac The content should be adapted to your system particularities but it'll give you sound information about working options. The files are in the autoconf format. The content can be retrofitted to configure flags (most of the time by swapping _ and - i.e. enable_64bit_flags="yes" becomes configure --enable-64bit-flag="yes"). Alternatively copy the .ac to your /home/xxx/.abinit/build/hostname.ac (adapt hostname to your system) and use a plain configure to read the options file.

Kind regards,

Alain

You can also copy the config file at the top of your source tree, if you wish to play with it more easily.
