[webkit-dev] problems in cross compiling webkit - Execution of JavaScriptCore/kjs/create_hash_table aborted due to compilation errors.

[Bn, Sharath]

I modified the line
- my $fh = new File::Temp(
+ my $fh = File::Temp->tempfile(

And I get some error like this

JavaScriptCore/pcre/dftables JavaScriptCore/pcre/chartables.c
Error in tempfile() using /tmp/File::Temp.in: The template must contain at least
 4 'X' characters
 at JavaScriptCore/pcre/dftables line 245
make: *** [JavaScriptCore/pcre/chartables.c] Error 255

I modified the line
- my $fh = new File::Temp( to
+ my $fh = File::Temp->new(

And I get some error like this

JavaScriptCore/pcre/dftables JavaScriptCore/pcre/chartables.c
Can't locate object method "new" via package "File::Temp" at JavaScriptCore/pcre
/dftables line 245.
make: *** [JavaScriptCore/pcre/chartables.c] Error 255

Pls let me know how to solve this build error

Filed this bug to cover the create_hash_table fix for Perl 5.10:

https://bugs.webkit.org/show_bug.cgi?id=21831

It would seem the "Object Interface" for File::Temp has changed in Perl 5.10:

    $fh = File::Temp->new(TEMPLATE => $template);

Originally you could do this:

    $fh = new File::Temp($template);

It looks like the only way to fix this is to use the File::Temp->tempfile() method instead.  What a pain.

These scripts appear to have the same issue (because I wrote them?!):

WebKitTools/Scripts/bisect-builds
WebKitTools/Scripts/sort-Xcode-project-file

I filed:

https://bugs.webkit.org/show_bug.cgi?id=21832

I should have a patch up shortly to fix all three scripts.
