Trying to find why lazarus crashes at start in win98 I found a courious
problem, global variable IsConsole is true when it should be false as
lazarus is built as a gui application.
Digging I found that IsConsole is set in two functions in wprt0.as:
_mainCRTStartup sets to true and _WinMainCRTStartup sets to False, this
cause a wrong setup of standard Output that DebugLn (lclprocs.pas) use to
emit debug messages.
It seems that this functions are 'used' in the linker script, for example
ld .--verbose shows that by default a ENTRY(_mainCRTStartup) it's used. I
looked into the generated lazarus link.res file and didn't find a ENTRY
section so I guess it uses the default and that's why even when lazarus is
a gui app, it's linked as a console app.
To demostrate this I modified the link.res script to inculde
ENTRY(_WinMainCRTStartup) section and then linked, the resulting
lazarus.exe file now behaves as a gui app and won't crash at start.
It seems that WriteResponseFile lacks the code to add the ENTRY section to
the link.res script but I don't know if it's supposed to be there or
should it be in another stage, any comments?
You need to use {$apptype gui} or use the -WG parameter. For the compiler
it is not known if the application needs a console or not.
