linker errors because you do not show perl58.lib file to linker?

Wierd. Should work. All needed should be in that dir...C:\Perl\lib\CORE... I forgott to add the link to that lib for the linker, but this _should_ be working!

gcc.exe "C:\test\start.c" -o "C:\test\start.exe" -I"C:\Dev-Cpp\include" -I"C:\Perl\lib\CORE" -L"C:\Perl\lib\CORE" -L"C:\Dev-Cpp\lib"

Notive the -L"C:\Perl\lib\CORE" part. Also, the perl58.lib is there. Aswell as PerlEz.lib.
Still no go though...

on windows applications w/o console window could be:
• for perl scripts, started with wperl (instead of perl)
• for any "console"-based application to make it w/o console window you must once invoke the command

  editbin blablabla.exe /subsystem:windows

Returning to your previous question, no, you do not required to build perl in order to build start.exe, and you can avoid building perl at all :):)

ps English sorrey mine :)

editbin?

Err, Windows got this start.com (or is it .exe?), and apparently I've been using that instead of your start.exe! Explains the terminal window. I renamed that to s.exe and then I got this message box about trying s.pl on 4 different locations (just as you expect looking in the start.c code...) However, isnt it supposed to run the thing given as argument?

"s.exe tktests.pl" still says the same about not finding s.pl!

I'm a little bit confused now...

Update: Ofcource! I renamed this s.exe to tktests.exe. However, runing it didn't do anything. As nothing seems to be happening! :/ Hmm...
