DBD::Sybase 1.15 Makefile.PL run on OS X environment gives error:
Can't find any Sybase libraries in /usr/local/freetds/lib or /usr/local/freetds/lib64 at Makefile.PL line 156, <IN> line 44.
Makefile.PL lines 144-146:
my @libdir = ( 'lib', 'lib64' );
print "$^O\n";
if ($^O =~ /win/i) {
@libdir = ( 'dll' );
}
Regex on second line 145 (second line in snippet) looks for 'win' in operating system type variable $^O.
Intent is to switch to 'dll' directory on windows systems.
Inadvertently switches to 'dll' on 'darwin' systems. $^O eq 'darwin' on OS X.
Two recommendations:
1. Avoid switching to 'dll' directory on OS X systems using negative look behind to ensure 'win' is not preceded by 'dar'.
2. Avoid generic error message on die that conveys libraries are missing from 'lib' or 'lib64' when directory checked was 'dll'.
Updated code in red:
my @libdir = ( 'lib', 'lib64' );
if ($^O =~ /(?<!dar)win/i) { # added negative look behind to preclude switching to dll on 'darwin' systems.
@libdir = ( 'dll' );
}
my $checkeddirs; # declares variable to hold directories actually checked
foreach $libdir ( @libdir ) {
$checkeddirs .= "$SYBASE/$libdir "; # compiles the list of directories actually checked
if ( -d "$SYBASE/$libdir" ) {
if ( checkLib($SYBASE) ) {
$libfound = 1;
$libsub = $libdir;
}
}
}
die "Can't find any Sybase libraries in: $checkeddirs" # correctly states what library folders were checked
unless $libfound;
