Attempting to configure mpich-3.2b1 for the SolarisStudio12.4 suite... Issues around complex.h (Yes, I'll have to look for prerequisites) and the message about FORTRAN integer length - which seems to have been dealt with a couple of years ago, and only in the ifort context? CROSS_F77_SIZEOF_INTEGER seems to be ignored; I've tried all of 1,2,4,8... Many thanks! checking complex.h presence... yes configure: WARNING: complex.h: present but cannot be compiled configure: WARNING: complex.h: check for missing prerequisite headers? configure: WARNING: complex.h: see the Autoconf documentation configure: WARNING: complex.h: section "Present But Cannot Be Compiled" configure: WARNING: complex.h: proceeding with the compiler's result configure: WARNING: ## -------------------------------- ## configure: WARNING: ## Report this to [email protected] ## configure: WARNING: ## -------------------------------- ## checking for complex.h... no checking size of _Bool... 0 checking size of float _Complex... 0 checking size of double _Complex... 0 checking size of long double _Complex... 0 checking for _Bool... no checking for float _Complex... no checking for double _Complex... no checking for long double _Complex... no checking for size of Fortran type integer... 0 checking for size of Fortran type real... 0 checking for size of Fortran type double precision... 0 checking whether integer*1 is supported... yes checking whether integer*2 is supported... yes checking whether integer*4 is supported... yes checking whether integer*8 is supported... yes checking whether integer*16 is supported... no checking whether real*4 is supported... yes checking whether real*8 is supported... yes checking whether real*16 is supported... yes configure: error: Unable to configure with Fortran support because configure could not determine the size of a Fortran INTEGER.
