When I don't want to use the vcpkg to install package, with:pkgs: "", but report an error?
I intend to install package for other vcpkg manually.

[johnwason]

I have no idea what you are asking.

There is an issue that error messages may not be displayed due to the temporary file capturing output. It will be fixed sometime using tee when I have a chance.

Can you try johnwason/vcpkg-action@master? It should print out an error message now.

I have this exact same problem. The problem is that I previously used the vcpkg manifest file, but now I want to install the packages individually, while still keeping the vcpkg.json file in the project's root. vcpkg-action is picking this file and assuming manifest mode, thus giving an error. I only found out this was the case after doing what @johnwason instructed. The error is:

Error: Process completed with exit code 1.

Is there any way to keep the file vcpkg.json and install the packages individually?

[johnwason]

@MangaD I think it is vcpkg itself picking up the manifest file rather than this action. Try adding
-DVCPKG_MANIFEST_MODE=OFF to your cmake command line.

[johnwason]

Also the manifest-dir must be removed from the action config.

[MangaD]

@johnwason I removed the manifest-dir entry and also tried to set it to the empty string. Both attempts failed. Adding -DVCPKG_MANIFEST_MODE=OFF to the cmake command line will not fix the issue because I only invoke cmake after this action runs. But perhaps I may try setting this as an environment variable and see if it works for vcpkg-action. I'll let you know soon after my current action runs. :)

[johnwason]

Can you link me to the workflow file and the action log?

[MangaD]

Sorry, I deleted the action as I'm rewriting history as I attempt to solve this problem. The workflow file is temporarily available here: https://github.com/MangaD/cpp-project-template/blob/main/.github/workflows/build-release.yml#L106

[johnwason]

I have recreated the problem... I will see if I can fix it.

[MangaD]

I just tried setting the environment variable VCPKG_MANIFEST_MODE: OFF for this step, but it did not work.

It appears that vcpkg will search the parent directory tree for vcpkg.json, and there is no easy way to disable this behavior. My suggestion is you check out the source in a src directory instead of having it check out to the root directory. This way vcpkg won't find the vcpkg.json file. I have found checking out the source in a subdirectory helps with a lot of other issues. This is a very complicated example but it shows how I use a source subdirectory: https://github.com/robotraconteur/robotraconteur/blob/master/.github/workflows/main.yml
