[lazarus] Compiling lazarus

Tue Nov 18 05:46:38 EST 2003

I have 256M of memory and I tried to compile lazarus wit FPC 1.19 to see
if this could solve the problem.
Now, I've compiled Lazarus with FPC 1.0.11 these are the steps that I
follow:

$ LANG=es
$ lazarus

Gdk-WARNING **: locale not supported by C library
[FORMS.PP] ExceptionOccurred
  Sender=EACCESSVIOLATION
  Exception=Access violation
TApplication.HandleException Access violation
TApplication.HideAllFormsWithStayOnTop :TSPLASHFORM
[FORMS.PP] ExceptionOccurred
[FORMS.PP] ExceptionOccurred

But if I set LANG to en_US Lazarus return the following error:

$ LANG=en_US
$ lazarus

[FORMS.PP] ExceptionOccurred
  Sender=EACCESSVIOLATION
  Exception=Access violation
TApplication.HandleException Access violation
[FORMS.PP] ExceptionOccurred
[TgtkObject.Destroy] WARNING: There are 1 unreleased DCs, a detailed
dump follows:
[TgtkObject.Destroy]  DCs:   08590334
[TgtkObject.Destroy] WARNING: There are 7 unreleased GDIObjects, a
detailed dump follows:

[TgtkObject.Destroy]   gdiBitmap: 1
[TgtkObject.Destroy]   gdiFont: 4
[TgtkObject.Destroy]   gdiPen: 2

I've tried to make a backtrace following the steps that the other day
Marc explained me:

gdb lazarus
break TAPPLICATION__HANDLEEXCEPTION
run
bt

This is what gdb shows on screen:

My knowledge isn't enough big for debug this problem, I hope you could
debug and correct it.
Thanks

PS: Feel free to correct me if I have mistakes in my english ;)
