planetary_data.f90 compilation fails with gfortran 4.2 #1

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Using gfortran 4.2:

$configure gfortran
$cd modules
$make
gfortran -c -g -O0 -fPIC -fbounds-check -pedantic -Wall  planetary_data.f90
planetary_data.f90:168.93:

 * planetary_radii(1) * (planetary_densities(1)/planetary_densities(14))**(1.0_
                                                                          1

Error: Exponent at (1) must be INTEGER for an initialization expression
planetary_data.f90:240.46:

       CALL getenv("OORB_DATA", OORB_DATA_DIR)
                                             1
Warning: Intrinsic 'getenv' at (1) is not included in the selected standard
make: *** [planetary_data.o] Error 1

According to the following:
http://gcc.gnu.org/ml/gcc-bugs/2008-02/msg02763.html  this is due to a
limitation imposed by the F95 standard, but ignored by most compilers.  By
switching to gfortran 4.5, the problem disappears.

An ideal fix would be to change the contents of planetary_data.f90 so that
they could be compiled by any version of gfortran.

Keep up the great work, guys!
