Is it possible to find somewhere a procedure explaining how to activate the compilation for a win64 target?did you download/install the cross compiler ppcrossx64.exe ? that's the version of the compiler that can produce a 64bit executable for Windows.
Thank you very much again.
Unfortunately the compilation fails in rtl\win64, with this message:
Makefile:216: *** The Makefile doesn't support target i386-win64, please run fpcmake first. Stop.
It's quite complicated to understand for a novice how to fix this problem... I've tried to do different things by digging in the docs, but without success so far.
Maybe I should give up rebuilding the units? Actually I only need to be able to set a low level callback when an exception is raised, so I can log all exceptions. If this is possible without rebuilding system and sysutils, it would certainly be much easier for me. But I haven't seen how I could do that yet.
I don't plan to use the SSE instructions in my program.
