Can't build on Windows

I think I found the root cause: the node module is compiled with the /MT option (the C/C++ Run Time is to be statically linked)
But the node module is linked to cpu_features.lib, witch is itself built with a link to utils.lib...
The two libraries, cpu_features.lib and utils.lib are compiled with the /MD switch (C/C++ Run Time is to be dynamicaly linked)

That's not correct. On Windows with Visual Studio, all libs linked to a DLL must use the same option with respect to link to C/C++ Run Time. The module build fine after MANUALLY changing /MD to /MT in the Visual Studio projects for the two libraries.

I don't have access to Windows at the moment. Does this change fix it for you?:

I juste cloned and patched. What command should I launch in my cmd.exe to trigger the same kind of build that npm install is doing?

[mscdex]

Either npm install (I think) or if you have node-gyp installed globally, node-gyp rebuild.

[somanuell]

I had to do npm install nan, and after that I could do node-gyp configure and node-gyp build (or rebuild)

But the problem persist, the two libraries project .\deps\cpu_features\build\cpu_features.vcxproj and .\deps\cpu_features\build\utils.vcxproj are still with switch /MD

[somanuell]

Fof what it's worth, I tried to run the command:
cmake -DCMAKE_CXX_FLAGS_RELEASE="/MT" -DCMAKE_BUILD_TYPE=Release -DBUILD_PIC=ON -A Win32 ..
in .\deps\cpu_features\build and the output was:

[mscdex]

Huh.... what about -DMSVC_RUNTIME_LIBRARY=MultiThreaded instead ?

[somanuell]

Still failing to build, for the same reasons.
Full node-gyp build output with the new MSVC_RUNTIME_LIBRARY=MultiThreaded define:

You could take a look at https://stackoverflow.com/questions/14172856/compile-with-mt-instead-of-md-using-cmake
(I don't know cmake)

[mscdex]

That's where the suggestions I gave came from. I'm not a Cmake expert either.

[somanuell]

I managed to have cmake generates valid Visual Studio projects for the two libs from deps, that is: with the Code Generation Run Time Library set to Multi threaded (/MT) by running the command:
cmake -DCMAKE_C_FLAGS_RELEASE="/MT /O2 /Ob2 /DNDEBUG" -DCMAKE_BUILD_TYPE=Release -DBUILD_PIC=ON -A Win32 ..
in .\deps\cpu_features\build with output:
-- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19043.
-- Configuring done
-- Generating done
-- Build files have been written to: C:/xxxxxxx/git/cpu-features-source6/deps/cpu_features/build
Please not that with this define, I do not have the "Manually-specified variables were not used by the project"

But when I try to patch the binding.gyp file with:

•          'action': [ 'cd <(module_root_dir)/deps/cpu_features/build && cmake -DCMAKE_C_FLAGS_RELEASE="/MT /O2 /Ob2 /DNDEBUG" -DCMAKE_BUILD_TYPE=Release -DBUILD_PIC=ON -A <(cmake_arch) ..' ],
  

and then use node-gyg build I have:
c1 : fatal error C1083: Cannot open source file: '\MT': No such file or directory
SOMEHOW NODE-GYP CHANGE THE SLASH TO AN ANTISLASH!

[mscdex]

Are you using the latest version of node-gyp to rebuild? It seems that this behavior was reverted in node-gyp 8.0.0 with its inclusion of gyp 0.7.0:

msvs: On Windows, arguments passed to the "action" commands are no longer transformed to replace slashes with backslashes.

If you're still encountering this on node-gyp 8.0.0 or newer, you should post an issue about this on their issue tracker here because evidently that shouldn't be happening anymore.

Unfortunately as of this writing, npm hasn't pulled in node-gyp 8.0.0+, so it will be awhile yet before someone can npm install cpu-features and use that particular action command successfully.

[mscdex]

Also, which version of CMake are you using?

[mscdex]

Out of curiosity, what if you use a dash instead of a forward slash, supposedly that is supported by the msvs compiler/linker for their command line arguments as well:

cmake -DCMAKE_C_FLAGS_RELEASE="-MT -O2 -Ob2 -DNDEBUG"

[somanuell]

node-gyp 8.2.0
CMake 3.21.3

Yes, the dash trick made it!

cpufeatures.vcxproj -> c:\xxxxxxx\git\cpu-features-source7\build\Release\\cpufeatures.node
gyp info ok

Please publish a new version adding -DCMAKE_C_FLAGS_RELEASE="-MT -O2 -Ob2 -DNDEBUG" line 46 of the binding.gyp file.
I will then be able (I hope) to npm install ssh2 (on Windows)
