Since bar is quite large the compiler generates static allocation instead of automatic allocation on the stack. 5 on a HPC cluster, those common block variables are not zero. The libs for static compiling and dynamical compiling are different. It shares the common backend and middleend and has frontends for different languages. /program. I didn't notice you deleted it. Modified 9 years, 1 month ago. cc gfortran -c -flto baz. For instance, we may have installed a lib called "LIBNAME" already. In comparison to variables with pointer attribute the memory is managed automatically and will be deallocated automatically once the variable goes out-of-scope.

In order to compile under OS X the -static flag has to be removed. log. f still produces an executable that tries to link to dynamic library routines. Only options specific to (Some Fortran compilers provide this option under the name -static or -save. STATIC is exactly equivalent to SAVE, and specifies that an entity should be allocated in static memory. The documentation can also be generated by processing the source files with FORD. The compile process is controlled by SCONS (similar or derived from gnu Make). . I am passing the -static argument to the compiler (gfortran. In order to compile the source file source. Therefore the two options from intel and gcc are not identical, and more care needs to be taken to ensure large arrays in gfortran are not shared in static The issue is that when I compile this library with gfortran 4. The allocatable attribute provides a safe way for memory handling. dll library from the UMAT file and load it into ccx. It can gfortran –g –fbacktrace –ffpe-trap=invalid,zero,overflow,underflow,denormal –O3 –mcmodel=medium –o . Link all together: g++ . and later, Emit static functions into the object file, gcc -c -flto foo. -ftail-call-workaround-ftail-call-workaround=n Some C interfaces to Fortran codes violate the gfortran ABI by omitting the hidden character length arguments as described in This can lead to crashes because pushing arguments for tail calls can overflow the stack. If that works, I'll post it as an answer. The Gfortran flag -std=legacy disables warning for very out of date non-standard Fortran syntax that should not be used anymore. The aim is to only get the gcc/gfortran related libraries statically linked, all others, even if the exists in both, dynamic and static, should be used in their dynamic form. The gfortran command supports all the options supported by the gcc command. And I would like to compile all Fortran code to a single static library (*.
