RE: Missing socklen_t defintion on Windows 11 ARM

[Yann Bourdeau]

Hi Bruno,

        Thanks for helping!

        I have used your script and make sure every paths were fine.

        Did not work and double check everything. I have found the problem, it 
was between the keyboard and the chair 😊 I forgot to define => 
win32_target=_WIN32_WINNT_WIN10.

Thanks again.

[CCing bug-gnulib because that's where socklen.m4 comes from]

Indeed, that's the cause. On native Windows systems, winsock2.h is expected to 
be found; this header file is expected to define socklen_t.
The test "checking for socklen_t equivalent..." is only meant to be run for the 
sake of old Unix platforms (HP-UX, IRIX, OSF/1).

This suggests that your INCLUDE variable is missing some directory.

Here's how I set the INCLUDE and LIB variables in a MSVC 14.30 (= Visual C++ 
2022) installation for x86_64 on Windows 10.
For arm there will be changes needed, and for Windows 11 there will also be 
changes needed, I guess. And maybe the Visual C++ version (14.35.32215) is also 
not the same on your side as on mine.

===============================================================================
# Set environment variables for using MSVC 14.30, # for creating native 64-bit 
Windows executables.

# Windows C library headers and libraries.
WindowsCrtIncludeDir='C:\Program Files (x86)\Windows 
Kits\10\Include\10.0.22000.0\ucrt'
WindowsCrtLibDir='C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22000.0\ucrt\'
INCLUDE="${WindowsCrtIncludeDir};$INCLUDE"
LIB="${WindowsCrtLibDir}x64;$LIB"

# Windows API headers and libraries.
WindowsSdkIncludeDir='C:\Program Files (x86)\Windows 
Kits\10\Include\10.0.22000.0\'
WindowsSdkLibDir='C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22000.0\um\'
INCLUDE="${WindowsSdkIncludeDir}um;${WindowsSdkIncludeDir}shared;$INCLUDE"
LIB="${WindowsSdkLibDir}x64;$LIB"

# Visual C++ tools, headers and libraries.
VSINSTALLDIR='C:\Program Files\Microsoft Visual Studio\2022\Community'
VCINSTALLDIR="${VSINSTALLDIR}"'\VC'
PATH=`cygpath -u 
"${VCINSTALLDIR}"`/Tools/MSVC/14.35.32215/bin/Hostx64/x64:"$PATH"
INCLUDE="${VCINSTALLDIR}"'\Tools\MSVC\14.35.32215\include;'"${INCLUDE}"
LIB="${VCINSTALLDIR}"'\Tools\MSVC\14.35.32215\lib\x64;'"${LIB}"

export INCLUDE LIB
===============================================================================

It's all a bit of a search-and-guess game to find the correct values for these 
variables.
