To run a C program using the xMat, the xMat Fortran file has to be compiled as an object first and then linked to the program. For a single C file (e.g. Xmat_Oedo_hypo_vw96.c) this would be something similar to

gfortran -ffree-form -cpp -DCINTER -DNOBIB xmat.f -c
gcc xmat.o Xmat_Oedo_hypo_vw96.c -lgfortran -lm -o Xmat_Oedo_C

for Linux with GCC or from Windows with Intel compiler similar to

ifort /free /fpp /DCINTER /DNOBIB xmat.f /c
cl xmat.obj Xmat_Oedo_hypo_vw96.c /link /out:Xmat_Oedo_C.exe

As shown, it is important to define the macros CINTER and NOBIB next to the flags for free format and preprocessing when compiling.

The C code should use either the interface xmat_console_CInter or Dot_Values_CInter. The memory for input and output variables must also be managed on the C side.
