The windows/CMakeLists.txt attempts to download nuget and checks its integrity. So either the download or the validation fails. Does build/windows/nuget.exe exist?

It’s up to you if you want to download nuget manually and put it to your $PATH or disable the integrity check at your own risk by modifying the CMakeLists.txt.

build/windows/nuget.exe existed, how to modifying the CMakeLists.txt

i found codes in CMakeLists.txt below:

if (NUGET_DL_HASH STREQUAL NUGET_SHA256) add_custom_target(DEPENDENCIES_DOWNLOAD ALL) add_custom_command( TARGET DEPENDENCIES_DOWNLOAD PRE_BUILD COMMAND ${NUGET} install Microsoft.Windows.ImplementationLibrary -Version ${WIL_VERSION} -ExcludeVersion -OutputDirectory ${CMAKE_BINARY_DIR}/packages COMMAND ${NUGET} install Microsoft.Web.WebView2 -Version ${WEBVIEW_VERSION} -ExcludeVersion -OutputDirectory ${CMAKE_BINARY_DIR}/packages DEPENDS ${NUGET} ) else() message(FATAL_ERROR "Integrity check for ${NUGET} failed") endif()

[jnschulze]

Comment the line if (NUGET_DL_HASH STREQUAL NUGET_SHA256) and the corresponding else-block.

then i got a windows alert says 'this application not allowed launchering in your computer'

[jnschulze]

Looks like it's compromised in fact. What's the SHA256 sum?

CertUtil -HashFile nuget.exe SHA256

It should output

SHA256 hash of nuget.exe:
852b71cc8c8c2d40d09ea49d321ff56fd2397b9d6ea9f96e532530307bbbafd3
CertUtil: -hashfile command completed successfully.

Is it signed by MS?

Do you live in China btw?

,and yes,i do live in china. also i try to run 'nuget.exe',i got the same windows alert 'this application not allowed launchering in your computer'.

[TOKID]

ok, i will try, thank you for answer my question, help me a lot.

[jnschulze]

I've just published a new version (0.1.5) which prefers a local nuget over the downloaded one. So you just need to install it yourself.

Comment the line if (NUGET_DL_HASH STREQUAL NUGET_SHA256) and the corresponding else-block.

I tried that:

file(SHA256 ${NUGET} NUGET_DL_HASH)

if (NUGET_DL_HASH STREQUAL NUGET_SHA256)

add_custom_target(DEPENDENCIES_DOWNLOAD ALL)
add_custom_command(
    TARGET DEPENDENCIES_DOWNLOAD PRE_BUILD
    COMMAND ${NUGET} install Microsoft.Windows.ImplementationLibrary -Version ${WIL_VERSION} -ExcludeVersion -OutputDirectory ${CMAKE_BINARY_DIR}/packages
    COMMAND ${NUGET} install Microsoft.Web.WebView2 -Version ${WEBVIEW_VERSION} -ExcludeVersion -OutputDirectory ${CMAKE_BINARY_DIR}/packages
    DEPENDS ${NUGET}
)

else()

message(FATAL_ERROR "Integrity check for ${NUGET} failed")

endif()

But I'm still getting this error:

@jnschulze I am also getting the above error, its a new setup for me and I am not in china. Have nuget in my path. I have visual studio 22, not 19. Do you think that can be an issue ?

[crifurch]

I have same issues caused by missing nuget.com repo for packages. Verify that you have same problems try add sources location as pointed at https://docs.microsoft.com/en-us/microsoft-edge/webview2/get-started/win32#step-7---install-the-windows-implementation-libraries-wil

[PonyPC]

The literally solution is deleting the %appdata%\nuget\nuget.config file

[lucasjinreal]

Seriously?

/webview_windows/windows/CMakeLists.txt:77 (target_compile_features): target_compile_features The compiler feature "cxx_std_23" is not known to CXX compiler

"MSVC"

version 19.29.30147.0.

[lucasjinreal]

Please,...... stop using decent c++ version on c++ projects.............................

[steniljoseph]

Any updates on this issue , I am still getting the same issue in windows build...!

[ranjitIN]
