           Summary: Build scripts: unchecked return value in call to
                    system()
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mseaborn at google.com


gperf is invoked via system() in the Perl build script
WebCore/css/makevalues.pl, but the return value is not checked.  This means
that if gperf is not installed, makevalues.pl will not fail properly and will
produce incomplete output.  This causes build errors later on, and installing
gperf does not fix the build because the build system is not aware that
makevalues.pl's dependencies have changed.

There is a similar unchecked system() call in WebCore/css/makegrammar.pl.
