Unable to build on ARM64 (AARCH64)

[macintoshplus]

The file header stdint.h contains the line typedef unsigned long long uintmax_t;.

On build this line generate these errors:

I have search on Internet without found a solution.

When I apply this patch, the build successed:

But the type is wrong for a 64bits architecture.

I have try to add this code #define uintmax_t2 unsigned __int64 without issues.
On other project, I have define #define uintmax_t unsigned __int64 without issues.

I don't understand why this error occur on this project.

[macintoshplus]

I found a solution. This patch work for me with VS17 on ARM64

Indeed, this config.h is ancient (apparently hasn't been touched since 2015). That needs some work; see also winlibs/libiconv#14.

[macintoshplus]

The patch is not necessary for building the library for x86 and x64 processors.

I don't open a PR because I don't how to manage the difference? two config.h?

[cmb69]

I don't think there is the need for two config.h in this case. <stdint.h> is available as of Visual Studio 2010, and I don't think we need to support older versions (actually, I'm fine with only supporting VS 2015 or newer).

However, to me the proper fix seems not to ship any config.h at all, but to create it during build time (another story, though).

and ran

msbuild gettext.sln /p:Configuration=Release /p:Platform=x64 /p:PlatformToolset=v141 /p:WindowsTargetPlatformVersion=10.0.20348.0

and that seems to work fine (would need to install some older toolset and WinSDK, and do some real tests, though).

I'm not sure though if it's worth fiddling with the ancient gettext 0.18.3 we still use.

[macintoshplus]

I have read the original repository of gettext. It is not easy to extract the build logical to make port on windows. I don’t have experience to do this.

What is the interest to build the library with older VS version? Update libintl on supported versions?

For ARM64 I want only build PHP 8.4 and newer.

[cmb69]

Well, supporting older versions of Visual Studio may not be required; not 100% sure, since at least some of the winlib repos are apparently used by others.

And yeah, it seems to me the only sustainable way to be able to do regular updates would be to use Cygwin or MSYS2 to do the configuration and builds. See winlibs/winlib-builder#24 (which is about libiconv, but gettext should be pretty much the same).

Note that @mlocati, who provides the official gettext and iconv Windows builds, also uses a Cygwin toolchain (compiling and linking is apparently done with MinGW).

[mlocati]

I'm building the gettext binaries with mingw-w64 on cygwin.
There's a doc that list the supported ways to build gettext for Windows: see https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=blob;f=INSTALL.windows;h=3aa1c004a63005da4f356eee4345c1d493ae3433;hb=HEAD

PS: In the future I'm planning to distribute .h.and .lib files too for people using Visual Studio (and that will require building with MS Visual C).

[cmb69]

@mlocati, building with MSVC is indeed what I'm trying to do. The instructions in INSTALL.windows have been helpful, but I didn't want to setup the MSVC environment manually; that appears to be tedious and error-prone (INSTALL.windows seems to mix headers from Windows Kits\10\Include\10.0.10240.0 and Windows Kits\8.1\Include). Thus, I basically call vcvarsall.bat and then the login shell of msys2 (the "ignoble and ignominious hack" can easily be disabled). That sets up a working build environment. However, I've noticed that the build calls windres/gcc instead of rc.exe/cvtres.exe, so I've set up a minimalist windres wrapper (neither general enough nor production ready to provide upstream). There are a couple of yet unresolved issues (such as missing .pdb files), but it's basically working for libiconv.

@macintoshplus, maybe you are interested in checking the libiconv arm64 build.

[mlocati]

Maybe @bhaible can shed some light

Yes. That's the whole point of GNU Autoconf.

msys2 (the "ignoble and ignominious hack" can easily be disabled)

With that hack disabled, you are a step closer to a reliable build. In any case, I recommend to look at the test failures (both in gettext-tools/tests/ and in gettext-tools/gnulib-tests/).
