Debugging

[rtusrghsdfhsfdhsdfhsfdhs]

When trying to debug a 64 bit app in 32 bit Lazarus IDE i get the following error...

"/project1.exe": not in executable format: File format not recognized

You can't do that. You will need 64-bit OS and 64-bit GDB debugger to debug 64-bit programs. Probably you need 64-bit Lazarus, too.

Delphi 32 bit can compile and debug 32 & 64... how to do the same with Lazarus?

[Laksen]

Try to use  a 64bit gdb exe

[rtusrghsdfhsfdhsdfhsfdhs]

I use fpcup. Do I need additional parameter? 

fpcup.exe --fpcURL="trunk" --lazURL="trunk" --installdir="A:\development\"

It should work on a 64 bit PC, with a 32 bit lazarus installed. There is a 32bit to 64bit cross compile add on, and it includes the 64 bit gdb.

Otherwise set up the path to gdb with whatever macros you need:
$(LazarusDir)\mingw\$(TargetCPU)-$(TargetOS)\bin\gdb.exe

You will need 2 gdb, on. 32 bit , and one 64 bit.

Okay it works, however...

I try to add several macros in the Additions and Overrides but Lazarus won't even recognize it.

GDB_PATH:=D:\TDM-GCC-64\gdb32\bin\gdb.exe

But it recognizes this

$(LazarusDir)\mingw\$(TargetCPU)-$(TargetOS)\bin\gdb.exe
