Free Pascal IDE how to use 64bit Compiler

Hallo,
I thought I would never in my live ask that question because I am
rather fan of 16 bit (and 32   )
But where can I call the 64bit compiler from the Free Pascal IDE?!
I installed the Cross Compiler 64bit (3.0.4) for Windows and can call
it at command line.
The program works fine, maybe have to do some modifications I dont see
by now.
But in the IDE?   "Options, Compile" - "Compile, target" (only Win32
options)  I didnt find.
Who can help. thanks.

I don't know the answer to that question if you're not using Lazarus
as your IDE.

In Lazarus, from the menu, select the following:

Project --> Project Options --> Compiler Options --> Config and Target

The fp IDE uses its own internal compiler, not the installed command-
line one, so it doesn't matter whether you install a cross-compiler.

If anything, you may try building a 64-bit IDE with it, but note that
I'm not sure if it can be done. It it can be, it would be nice if you
told us

Best of lucks.

Yes that can be done. I am actually always using it both on Linux 64
and Windows 10 64.
Simply:
Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i make clean
all install OS_TARGET=win64 CPU_TARGET=x86_64 IDE=1 GDBMI=1
PP=\the\path\to\bootstrap\ppcx64.exeGiven a 64 bit starting compiler
or a 32 bit cross-compiler for win64 this will usually do the trick.
The above compiles a full 64 bit FPC including a 64 bit textmode IDE
fp.exe.
On Linux64 just change OS_TARGET=linux, change ppcx64.exe to just
ppcx64 (and use a linux path /).
I am not quite sure if IDE=1 is actually still necessary, but it used
to be and it doesn't harm to leave it in. This is a very old tried and
tested recipe.
GDBMI=1 is the default in 3.2.0 so may also not be necessary. It
requires a recent GDB, though. Higher than GDB 7.2. If for some reason
you must use an older GDB, leave it out.

You can even build a 32 bit IDE that targets x86_64 (e.g. make
crossall crossinstall IDE=1 PP=\a\32\bit\ppcrossx64) but it has been a
long time ago I built such a beast. Not recommended.

Hey Thaddy,
I never built my own IDE
But when it helps... Please tell me, where must I do (tried just the
installed ..\bin\x86_64-win directory where I found the ppcx64.exe)
I got a message "no rule to make target 'clean' "
I do need the sources?!  I guess you mean that by GDB?
I was just wondering why there wasn't any 64bit IDE for that. Nobody
needs? I can compile my program with batch fpc, no problem.
I have no special code or functions I need the help of the IDE with, I
only wanted to make effort of my ful computers memory with
compile 64bit because under 32bit the heap is smaller and then my
program starts divide and rule
