Build project without any connection to a PPmac

[sbrun]

I have a projet PPmac including C applications (background CApp)
When IDE is connected to the PPmac, I can build and download all without any problem.

If now, IDE is not connected to any PPmac (in order to prepare upgrade or ohters),
when i just try a simple build or re-build the project in order to recompile my C code, i got the followings errors :

E:\x\e\2022 02 24 - RT5 - copie (IDE 4.5.2.9\RT5.ppproj(370,5): error :       0 [main] make 16140 child_info_fork::abort: C:\DeltaTau\PowerPMAC\Compilers\bin\cygiconv-2.dll: Loaded to different address: parent(0xA00000) != child(0x820000)
E:\x\e\2022 02 24 - RT5 - copie (IDE 4.5.2.9\RT5.ppproj(370,5): error : make: vfork: Resource temporarily unavailable

Is there a way to don't have these errors ?

Thank's in advance.
