Molcas 7.8 has been released at the time of GCC 4.6.
I would not recommend to use more modern compilers to compile Molcas.

Possible solution:
1. if you don't use qmstat package - uninstall it
molcas uninstall nemo
2. change the reported line to:
(and submit a bug report to GCC - this is indeed on the edge of standard -
after preprocessor expansion of constants in parameter statement - the length of expression is over 72 chars).


: Hi,

: I've tried compiling Molcas 7.8 with GCC 4.8.1 and MVAPICH2 1.9 (since all other attempts have failed at 2+ nodes so far).

: I've encountered a bizzare problem during Fortran77 compilation of $MOLCAS/src/qmstat/eqras.f:

: As you can see, compiler thinks that the exponent is missing. Sure, it is missing, but it is in the line right below - for some odd, unforeseen reason. Is it possible to fix it somehow? The values are written as variables in the Fortran file and I wasn't able to fid out where they are stored at.

: Thanks in advance.

: Regards,
