I give up. Maybe it is my search (Windows) but I cannot seem to find the definition of the F77_CALL or F77_NAME macros. Either there are too many matches or the search just doesn't find it. For example where is the source for: F77_CALL(dpotri) ? Thank you. Kevin

Dear R-help, Sorry if this is way obvious. (It just wasn't for me...) Do all parameters passed to Fortran routines from C need to be declared as pointers? In various header files (e.g., Linpack.h), that seems to be the case. Also, what type should I declare in front of F77_NAME() for a subroutine? void? Thanks for any help!

Hello there I'm writing some c-code to solve a numerically tough problem for me in R. Looking in Lapack.h, i find the following line F77_NAME(dgesvx)(const int* fact, const char* trans, const int* n, and I believe that "fact" should've been char instead of int, i.e. F77_NAME(dgesvx)(const char* fact, const char* trans, const int* n, My reasoning: In the R-source: src/modules/lapack/dlapack.f I find the following lines:...

Full_Name: G?ran Brostr?m Version: R-2.1.1, 2.2.0 OS: Debian unstable Submission from: (NULL) (213.65.9.59) Some BLAS routines call xerbla for error messages, which results in a message like "LAPACK routine DGER gave error code -9". Suggested solution: In void F77_NAME(xerbla)(char *srname, int *info) { /* srname is not null-terminated. It should be 6 characters. */ char buf[7]; strncpy(buf, srname, 6); buf[6] = '\0'; error(_("LAPACK routine '%6s' gave error code %d"), buf, -(*info)); } change 'LAPACK' to ...

...routines can be called (not functions), probably because of the non-standard way the compilers map FORTRAN function names to symbols in the DLL. This is consistent with the interface prototype for the BLAS routine zdotc contained in <R>/include/R_ext/BLAS.h, namely, BLAS_extern Rcomplex F77_NAME(zdotc)(Rcomplex * ret_val, int *n, Rcomplex *zx, int *incx, Rcomplex *zy, int *incy); But this seems to BOTH return a result, and pass the result as the first argument?

Hello All, In some package I use a c-routine which calls a fortran routine which expects a char-string as input. As per the writing R-extensions manual, the Fortran routine is declared in C as: void F77_NAME (setoptions) (char **option); and then it is calles as follows: char **option; option = new char*[1]; option[0] = new char[256]; option[0] = strcpy(option[0],"Iteration Limit = 100"); Rprintf(option[0]); F77_CALL (setoptions) (option); Unfortunately this does not wor...

Is there a way to exit gracefully from dynamically loaded Fortran, (several layers down), if an error condition is detected? I.e. suppose I'm within a subroutine called by a subroutine, ..., called by .Fortran(); I want to give up gracefully if an error condition is detected. If I say something like if(x .gt. 42.d0) stop then indeed everything stops, i.e. R falls over. I'd
