I’ve come across a weird problem. After using FB for years, suddenly when I run my D11 app built from FinalBuilder, it falls over with an AV in one part of the code, but when I build via the IDE it runs absolutely fine. Conditional Defines are the same and Search Path & Library path are set to use those from delphi/project. I can see in the output folder there’s a file myproject.used which I’m assuming is the options passed to the command line compiler. Firstly is there anyway to get something similar out of the IDE, so I can compare the two and secondly any other ideas as to how to work out what’s going wrong ? Many thanks David ---

Very odd. Must have been a rogue dcu somewhere as editing the problem pas file seems to have cured. What’s odd is that all the path’s are the same between the two compiler setting options and I delete all dcu’s as part of the Finalbuilder script ---

Hi David In the delphi IDE, you can get the command line from Messages, Build tab, it will have an node like `dcc32 command line for 'yourproject.dpr'` expand that node to see the command line options. My go to answer for differences between the IDE and FB built applications is usually resources, in particular the manifest file.
