Build Scripts

[SomersetGraham]

Hello
I am trying to create a build script for my application.
When it runs I get the following errors

Code: [Select]

Running build script - Model.Code      
C:\QTProjects\EATest\TestEA>C:\mingw\bin\mingw32-make.exe -s -f Makefile.Debug       
process_easy: DuplicateHandle(In) failed (e=6)      
process_easy() failed to launch process (e=6)      
c:\Qt\4.7.2\bin\uic.exe testea.ui -o ui_testea.h       
Counted 4 args in failed launch      
C:\QTProjects\EATest\TestEA Build completed with exit code 2      

Does anyone know what this error message means?

TIA

Graham
