Linux Fedora Core 6, x86_64.

I have some problems with gcstar 1.0.0, so I decided to try version 1.1.1. I downloaded it from this site, untarred, and run installer:

(Current directory is ~/tmp/gcstar, ~/gcstar EXISTS and writable.)

$ ./install --prefix=~/gcstar

Hello,

I think the problem is because you used ~ in your path. There is for the moment nothing in the installer to replace it with the home directory as the shell does.

Please try again with a full path. e.g.

Code:

./install --prefix=/home/debugger/gcstar

I will update that in a future version once you confirmed that's the problem.

Hi,

Thanks for quick reply.

No, ~ does not matter. If I use full path /home/debugger/gcstar, result is exactly the same.

I think we could localize the problem faster and more easily if error message contains the name of directory.

Hi,

I found the bug:

install:223:

Code:

    eval 'mkpath $dir' if (! -e $dir);
    if (-w $dir && !$@)
    {
        clean $dir unless ($withoutClean);
        installMenu unless ($withoutMenu);
        doInstall $dir;
        $dir .= '/' if $dir !~ /\/$/;
        print "\n",$lang{InstallEnd},"\n",$lang{InstallNoError},"\n",$lang{InstallLaunch},$dir,"bin/",$binName,"\n";
    
        exit 0;
     }
     else 
     {
         print $lang{InstallNoPermission}."\n";
         exit 0;
     }

$dir exists and is writable; $@ is not empty (it contains error messages related to some optional modules); so ( -w $dir && ! $@ ) is false, control flow goes to "else" part and prints wrong error message...

Hello,

I didn't have time to look at this problem. So thank you very much for your investigations.

Could you please print the content of $@ when it fails. So we could know where the problem exactly is. As we used an eval, this variable should have been reseted. So it could only contain errors about this instruction.

debugger · 2007-03-21 09:16:02

Tian,

eval is NOT executed because the directory exists:

Code:

eval 'mkpath $dir' if (! -e $dir);

It is Perl tricky syntax -- I prefer this variant:

Code:

if ( -e $dir ) {
    eval 'mkpath $dir';
};

a bit more talkative, but much more readable.

Ok, let us get back. This eval is NOT executed, because $dir EXISTS. $@ contains error messages from the previous eval -- something about not found modules (I do not have installed few optional modules).

I would recommend something like this:

Code:

    if ( ! -e $dir ) {
        eval { mkpath( $dir ); };
        if ( $@ ) {
            print( "Cannot create dir \"$dir\": $!\n" );
            exit( 1 );
        }; # if
    }; # if

$@ should be checked if and only if eval is really executed...

Oops, stupid me. I will change this to something as you suggested. Thank you very much for your help.

Thank you for the program and accepting suggestions. I have some more... ;-)
