Hi, The 'dmake -f makefile.mk' step goes ok for a couple of minutes until we get to: ###################### Creating Makefile.PL in cpan/Archive-Extract for Archive::Extract Running Makefile.PL in cpan/Archive-Extract C:\comp\perl-5.15.6\win32\..\miniperl.exe -I../../lib Makefile.PL INSTALLDIRS=perl INSTALLMAN1DIR=none INSTALLMAN3DIR=none PERL_CORE=1 ###################### At which point I get a popup complaining that libgcc_s_dw2-1.dll was not found. But that file is in C:\MinGW\bin - which is in my path: ###################### C:\comp\perl-5.15.6\win32>path PATH="C:\Program Files\Windows NT\Accessories";C:\_32\dmake;C:\MinGW\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\batch C:\comp\perl-5.15.6\win32>\MinGW\perl\bin\perl \_32\plx\which.pl libgcc_s_dw2-1.dll Found C:\MinGW\bin\libgcc_s_dw2-1.dll ###################### I can acknowledge both the pop up and the ensuing notification that perlglob.exe has stopped working ... and the build then continues on for a few seconds until: ###################### Creating Makefile.PL in cpan/Archive-Tar for Archive::Tar Running Makefile.PL in cpan/Archive-Tar C:\comp\perl-5.15.6\win32\..\miniperl.exe -I../../lib Makefile.PL INSTALLDIRS=perl INSTALLMAN1DIR=none INSTALLMAN3DIR=none PERL_CORE=1 ###################### At which point the same thing happens again, and so on, ad nauseam ....... Is this is a known issue ? Have I missed doing something important in the editing of the makefile.mk ? Why do these miniperl commands clobber my path ? As an interim workaround I've just stuck a copy of libgcc_s_dw2-1.dll in the same folder as miniperl.exe (ie in the top-level source folder). This seems to be working ok - the build is still running as I send this email. Cheers, RobThread Next
