Undefined Reference Fortran Error


You can make my trivial example fail the same way, without IMPLICIT NONE. An example of one of these "old subroutines", which does not give any complaint, is: In the main program: call get_dim(n_atom,nSnap,mol) In the fileio.f90: subroutine get_dim(n,n_snap,tape) implicit none integer,intent(in) :: tape jtbell, Aug 18, 2014 Aug 18, 2014 #12 sketos MY FILE ( StatiTests.f95) WHICH CONTAINS THE MODULE: module StatisticTests implicit none contains SUBROUTINE kstwo(data1,n1,data2,n2,d,prob) INTEGER n1,n2 REAL d,prob,data1(n1),data2(n2) !CU USES probks,sort Join them; it only takes a minute: Sign up Error in fortran, undefined reference to subroutine up vote 0 down vote favorite I am writing a subroutine and main function to http://centralpedia.com/undefined-reference/undefined-reference-to-fortran-error.html

sketos, Aug 16, 2014 Aug 16, 2014 #4 Borek Staff: Mentor It doesn't work, because you are not compiling whole project, only part of it. f95 new.f95 -o new -->./new This doesn't work because, although 'new' does contain a main program, it does not contain the subroutine 'sub1'. So the statement says: Please compile and subsequently link test1.f90 to modtest.o, and produce a file called test1 as the final output. In this case I would do it like you suggest, but if I wanted to output a table with 8 strings, floats and integers intermixed, I would do it this way.

The error message means that your program wants to use something named 'probks_', and 'ld' can't find it.

Personally I am not familiar with Fortran, much less with Plplot, but I believe you require something along the lines of: Code: gfortran -I/usr/lib/fortran/modules/plplot testplot2d.f90 -o testplot2d -L/usr/lib/fortran/modules/plplot -lplplot Of course, Thanks Chris Windmeier !------------------------------------------- PROGRAM MAIN USE MODULE1 . . . But the .mod file only contains information about the argument lists of the subroutines in the module, so the compiler can check you are calling them correctly. http://stackoverflow.com/questions/29639760/error-in-fortran-undefined-reference-to-subroutine How strange is it (as an undergrad) to email a professor from another institution about possibly working in their lab?

If the programmer wants to access the mult module procedure they "must not" declare the function separately. Having both the module providing the interface and the declaration is confusing the compiler.
