Hi, I am trying to compile a FORTRAN program to call from R under Windows 7 but I am having problem in the compiling step. To demonstrate this is the program testit.f:
------------------------------------------ subroutine TESTIT(x,n,m) dimension x(n) do 10 i=1,n 10 x(i)=x(i)**m end -------------------------------------------- When I compile it with gfortran I get the following error: -------------------------------------------------- c:\MinGW\programs>gfortran testit.f -o testit.o c:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../libmingw32.a(main.o):main.c:(.tex t+0xd2): undefined reference to `WinMain@16' collect2: ld returned 1 exit status. ---------------------------------------------------- I should add that a program like the following hello.f compiles with no problem. ------------------------------------------ READ (*, *) YOURNAME WRITE (*, 200) YOURNAME 200 FORMAT(//,' Hello ',A/) STOP END ------------------------------------------ I realize that this is not directly a question about R but I guess there are some people here who have compiled FORTRAN programs under Windows 7 to call from R. I appreciate any help to fix the problem. /Mikael [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
