Can Lazarus 64-bit for Windows compile to 64-bit for Windows?

Question

I downloaded, what i thought, would be the 64-bit version of Lazarus:

Although it downloads a 32-bit build:

And after installing it, the IDE is 32-bits:

And it builds 32-bit binaries:

Changing the targeting options to win64, win64, win64:

Gives an error that Lazarus doesn't support 64-bit:

Reading the somewhat dated Cross compiling Wiki page gives the instructions on how to make the 64-bit Lazarus work on 64-bit machines:

From win32 to win64

If you are compiling the 2.1.1 or greater branch of fpc you can just do:

$ make all OS_TARGET=win64 CPU_TARGET=x86_64

and then

$ make crossinstall OS_TARGET=win64 CPU_TARGET=x86_64

which, if you follow, just gives a few thousand errors:

The common suggestion is to abandon the Lazarus IDE, altogether, and use a fork known as CodeTyphoon. Downloading that 500 MB, and installing it, i couldn't find an IDE anywhere:

Which is confusing, because i thought CodeTyphoon was a Pascal Visual Programming Environment.

Before i go on

Before i go randomly stumbling around, downloading gigabytes of stuff, let me just ask straight out:

Can Lazarus 64-bit for Windows compile to 64-bit for Windows?

Is there a 64-bit Lazarus for Windows, that can create 64-bit Windows binaries? Am i missing something, or is that functionality not in there yet?

And if the ability is in there, at least could someone commiserate that my confusion is understandable?

Answer 1

The following is from README.txt files on the SourceForge download pages (http://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2032%20bits/Lazarus%201.2/ and http://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2064%20bits/Lazarus%201.2/). However, those readme.txt files are apparently not included in the actual installation.

I have verified that installing the plug-in allows you to build a 64-bit application.

Two things:

1. there is an add-on for building Win64 applications in the 32-bit Lazarus IDE:

• Add-On for building 64bit Windows applications:

  lazarus-1.2.0-fpc-2.6.2-cross-x86_64-win64-win32.exe

  This file can be installed as add-on to the 32 bit Lazarus IDE (on Systems with Windows 32 or 64 bit), if you wish to develop for 64bit Windows too. If you install this on a 64bit Windows PC together with the 32 bit Lazarus IDE, you will also able to debug 64 bit applications.

1. the link to the 64-bit Lazarus IDE on the Lazarus homepage is incorrect (it points to the Win32 version). The link should be:

   http://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2064%20bits/Lazarus%201.2/lazarus-1.2.0-fpc-2.6.2-win64.exe/download

If you use the 64-bit IDE you'll need a similar (but different) plugin to build 32-bit binaries.
