# dotwrp.c This is a wrapper for all of the BLAS functions in Apple's vecLib Framework that have compatibility issues between F2C and GNU Fortran. The functions fixed are: cdotc cdotu zdotc zdotu sdot snrm2 sasum scnrm2 scasum All other BLAS routines work correctly with or without the -ff2c flag. Instead of using this package, you could instead compile your FORTRAN with -ff2c. However, if your code exports any functions returning single-precision or (single- or double-precision) complex results, then any code that calls those functions will be forced to follow F2C conventions as well. To use, just add dotwrp.c to your existing project, or link to it statically. This is an expansion of the "dotwrp" project by tenomoto: https://github.com/tenomoto/dotwrp We've chosen to convert the f90 code to c so we can take advantage of the __attribute__((visibility ("hidden"))) settings. This ensures that the symbols generated by this code are not visible outside of your project---which is important if you're mixing multiple FORTRAN-based projects together.
