--- Comment #6 from Raphael Groner projects.rg@smart.ms --- It turns out that lazbuild needs a bugfix to get some doublecmd build success.
Lazarus 1.4 has a bug in lazbuild utility. I wrote about it to Lazarus bugtracker and it was fixed (revisions 48892,48893). This fix will be included in Lazarus 1.4.2 .
