I just made tests on another computer where I have ExtUtils::F77
version 1.18 installed and I downloaded version 1.19.
$ perl -MExtUtils::F77 -e ''
ExtUtils::F77: Version 1.18
Loaded ExtUtils::F77 version 1.18
Found compiler f77
Found compiler gfortran
ExtUtils::F77: Using system=Linux compiler=GNU
Runtime: -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib -lgfortran -lm
ExtUtils::F77: Validating -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib
-lgfortran -lm [ok]
ExtUtils::F77: Compiler: gfortran
ExtUtils::F77: Cflags:
$ perl -Mblib -MExtUtils::F77 -e ''
ExtUtils::F77: Version 1.19
Loaded ExtUtils::F77 version 1.19
Found compiler f77
Found compiler gfortran
ExtUtils::F77: gfortran version 5.3.1
ExtUtils::F77: gfortran version 5.3.1
ExtUtils::F77: Using system=Linux compiler=GNU
Runtime: -L/usr/lib/gcc/x86_64-linux-gnu/5 -lgcc_ext.10.5 -lgcc_s.10.5
-lquadmath -L/usr/lib -lgfortran -lm
Found compiler=GNU - skipping validation of -L/usr/lib/gcc/x86_64-linux-gnu/5
-lgcc_ext.10.5 -lgcc_s.10.5 -lquadmath -L/usr/lib -lgfortran -lm
ExtUtils::F77: Compiler: gfortran
ExtUtils::F77: Cflags:
Again, version 1.19 adds the non-existing libraries -lgcc_ext.10.5
-lgcc_s.10.5
I checked the diffs on the two sources of F77.pm (attached)
I guess the problem is in the lines:
if ($compiler eq 'GNU') { # Special gfortran case since it seems to
have lots of random libs
print "Found compiler=$compiler - skipping validation of $Runtime
\n";
}else {
$ok = validate_libs($Runtime) if $flibs ne "" ;
}
and
# Sigh special case random extra gfortran libs to avoid PERL_DL_NONLAZY
meltdowns. KG 25/10/2015
$append = "";
if ($compiler eq 'gfortran' && $version >= 4.9) { # Add extra libs for
gfortran versions >= 4.9
# if ($compiler eq 'gfortran' && $Config{osname} =~ /darwin/ &&
$Config{osvers} >=14) { # code variant for OS X only
$append = "-lgcc_ext.10.5 -lgcc_s.10.5 -lquadmath";
}
return( "-L$dir $append -L/usr/lib -l$lib -lm" );

Luis
