Now that I have the win64 version installed how do I go about making
it possible to build for both 32 and 64 bit environments?
In my experience, there are two methods to achieve this.
1) Use the win32 FPC compiler and the win64 FPC cross-compiler. In
Lazarus you set up fpc.exe as your compiler. In the Project's Compiler
Settings, it will pass a -T command line parameter to fpc.exe which
in turn will execute the correct ppc*.exe executable to generate
the appropriate binary for your project.
2) This option doesn't use a cross-compiler. Instead I start off with
64-bit versions of FPC and Lazarus. I normally use FreeBSD for
development, but the same configuration can be applied to Windows or
Linux. I install FPC is a specific directory layout so it supports
multiple targets with one fpc.cfg file. For example:
c:\fpc-3.0.4
\x86_64-win64
\bin
\lib
\share
\i386-win32
\bin
\lib
\share
The fpc.cfg search paths and such with then use the built-in macros to
resolve the correct path location. For example, my FreeBSD system have
lines as follows:
-Fu/data/devel/fpc-$fpcversion/$fpctarget/lib/fpc/$fpcversion/units/$fpctarget
Adapt the fpc.cfg for windows to match your FPC install hierarchy and
appropriate $fpc* macros.
In Lazarus IDE I then use "IDE Options -> Environment -> FPC" to select
between the FPC compilers and related FPC Source directories.
The same can be done (actually even easier) in MSEide because MSEide has
better IDE/Project macro support. So in MSEide I have different keyboard
shortcuts to compile my projects for different targets. I don't have to
toggle any global settings.
In my Delphi XE5 environment I can do this easily in the project
options where the target can be switched for each configuration.
Delphi simply hides much of the underlying configuration from the
developer - after all, I hope that is why you pay them so much. Delphi
ships with different compilers (depending on the version you bought
(Starter, Pro, Enterprise, Studio, Architect, add-on packages
installed). Depending on the version, in then enables you to specify new
targets in the Project Options dialog, which in turn uses different
search paths and compilers.
CodeTyphon is a spin-off of Lazarus, which ships with many
cross-compilers all ready for you out of the box. They did some
excellent work in simplifying that process and getting later updates.
This is closer to the experience you get with Delphi. There are some
other stuff I don't like or agree with about that project, but that is a
personal opinion and another matter.
