The current directory is /somewhere and you want to compile a file in the
directory /anywhere/foo.f90. The foo.f90 file looks like
PROGRAM foo
INCLUDE 'bar.inc'
WRITE(*,*) 'Hello world'
END PROGRAM foo
The file bar.inc is located in /somewhere, the current directory. You attempt
to compile the file with the command
gfortran -o test /anywhere/foo.f90
The compiler exits with the error that bar.inc cannot be found. The solution
for the build to occur is to either
a) Place bar.inc into /anywhere
b) Specify -I. when compiling
Why this may be a bug:
- The behaviour for the USE statement is different--gfortran will search both
the current directory and the source file directory.
- If you compare this behaviour to the Intel Fortran compiler (for comparison
purposes only), the behaviour for both the USE and INCLUDE is the same and
matches the behaviour that gfortran has for the USE statement.
This behaviour causes problems if you perform a VPATH style build.
