Feature Request: Support building FPC on MSYS2 on Windows (as
mingw-w64-fpc)
lazarus / 64-FPC development

----------------------------------------------------------------------

Hi everyone,

I contribute regularly to MSYS2, a Arch-Linux-like development
environment on Windows that provides both POSIX-compatible utilities
and native Windows toolchains via packages. I was wondering if FPC
could be built with MSYS2's mingw-w64 toolchain; specifically I would
like to create a mingw-w64-fpc PKGBUILD for MSYS2's MINGW-packages
repository. I know that currently only binutils on cmd.exe is used to
build FPC on Windows, but would it be possible to modify FPC's
makefiles so it could compile on MSYS2? Thanks.

I use MSYS on my old Windows XP for years and I can use FPC without
any problem.  Just added the PATH (at your computer "Properties") and
it work seamlessly.

That's actually a popular practice: Users sometimes use a separate gcc
build from a download and add it to their path, rather than using the
provided gcc package.

I totally understand what you mean, but I want users to be able to use
fpc on MSYS2 by using this command:

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 pacman -S
mingw-w64-x86_64-fpc
And they don't need to use a separate installer.

The FPC makefiles seek their own utils, but you can often pass your
own equivalents by passing environment variables (PWD=)

I don't know about anybody working on building under unix emulations
on Windows though. So it is hard to say what is needed, and if non
trivial, who would do it.

Note please don't submit modified makefiles. Changes should be made to
makefile.fpc's and the main template utils/fpcm/fpcmake.ini

 Yep, that was an issue at the beginning but right now it is solved. 
Just playing with Windows' PATH variable and a few FPC configuration
tweaking and done.  Not too hard IIRC.

The Lazarus/FPC makefiles are already compatible with MinGW-W64 Make
on Windows, just so you know... I've been using the builds of
Make/Strip/Strings/e.t.c from the Nuwen MingW distribution instead of
the FPC-provided ones for several years without any issues.

Isn't that just a matter of bundling any version of FPC you want into
whatever archive format Pacman expects, and uploading it to the
package repository?

The package would have to be compiled from source, and packaged into
the archive via makepkg (specifically makepkg-mingw for
mingw-w64-fpc), using only MSYS2 and their mingw-w64-binutils.

It actually turns out that FPC requires mingw-w64-make (mingw32-make,
not the MSYS2 version of make). I tested the build and it works now
without modifications. Will plan to add the package to the official
MSYS2 package repository.

Yeah, that's what I was saying.
