I have an error in the "-x" file test option. Found while building the
ExtUtils F77.pm module. The result, for me, was that the 'make test'
failed and died because a routine didn't recognize my fortran compiler
as being executable
(This module is a prereq for PDL)
F77.pm line 160
$F77config{Generic}{G77}{Compiler} =
find_in_path('g77','f77','fort77');
calls the subroutine at line 556
sub find_in_path {
my @names = @_;
my @path = split(":",$ENV{PATH});
my ($name,$dir);
for $name (@names) {
for $dir (@path) {
if (-x $dir."/$name") {
print "Found compiler $name\n";
return $name;
}
}
}
return '' if $^O eq 'VMS';
die "Unable to find a fortran compiler using names: ".join("
",@names);
}
But it can't find my g77 compiler. I thought the problem was the split
on colon's (:), WinXP uses semi's (;). But the reason seems to be that
the "-x" file test option does not work: the compiler is in my PATH,
but not recognized here.
Is this "-x" switch broken? Or is something configured wrong on my end?
At the moment, my WORKAROUND is to append '.exe' to each of the names
passed to find_in_path, and change the -x switch to -e.
