Cannot use vcpkg in manifest mode with cpp image
When using vcpkg in manifest mode, it is possible to specify a commit of the vcpkg repository to track via the builtin-baseline option, such as:
{
"name": "test-vcpkg-template",
"dependencies": [
{
"name": "expected-lite",
"version>=": "0.6.3"
}
],
"builtin-baseline": "01acfdfde3ed99280d3883a8fccd5fa4408f5214"
}
Devcontainer cpp image clones vcpkg repository using the --depth=1 option (link to the code) preventing usage of vcpkg in manifest mode, unless manually modifying the container image to fetch all git history.
Hi 👋
Thanks for opening the issue. To keep the cpp image size minimal, we are intentionally using --depth=1. However, I understand how the builtin-baseline option might become unusable due to this.
Doing a full git clone would significantly increase the size of the cpp image. @NoMore201, do you think cloning up to the last N commits would be useful to you?
Hello!
To be fair I'm not a vcpkg expert to tell if this is the right way to do things, since no one else complained so far. Anyway it is rather easy to modify the dev container to clone the entire history.
I would say to keep it like it is, unless someone else with more experience has something to add.
@samruddhikhandale For vcpkg to work correctly, it must not be shallow-cloned. If you ant to keep the container size small, I suggest adding vcpkg as a feature. This keeps image size down and enables vcpkg users to use vcpkg properly at the expense of a larger container.
I recommend you get in touch with the vcpkg team at Microsoft if you have further questions.
I just spent several hours debugging a working config that I was moving to dev containers because the installed vcpkg is broken for manifest mode. It makes no sense to intentionally hobble a specific mode and not document it in the readme.
Hello @willie ,
Thank you for raising your concern on this issue. Would you kindly let me know at which stage(while installing the packages using vcpkg in manifest mode or while building the project later) does this fail for you & also if possible would you kindly share the respective manifest file used for this instance? That could help me a great deal to bring this issue to a conclusion. There's a 3rd party feature available in devcontainer feature site but even there they are getting the vcpkg from git in shallow copy mode.
With Regards, Kaniska
In manifest mode, you add vcpkg to the CMakeLists.txt:
set(CMAKE_TOOLCHAIN_FILE "/usr/local/vcpkg/scripts/buildsystems/vcpkg.cmake" CACHE STRING "vcpkg toolchain file")
and then when you generate the build files, vcpkg reads the manifest and builds then. It's like the manual install step, but it's triggered by the manifest in this step
cmake -B out -G Ninja -D CMAKE_BUILD_TYPE=Debug
At that point, the shallow copy gives you all kinds errors.
I had to add this to my devcontainer dockerfile (VCPKG_FORCE_SYSTEM_BINARIES is for arm64):
# vcpkg
ENV VCPKG_FORCE_SYSTEM_BINARIES=true
RUN apt-get -y update && export DEBIAN_FRONTEND=noninteractive && apt-get install -y \
autoconf automake autoconf-archive
RUN cd /usr/local/vcpkg && git fetch --unshallow && git pull --ff-only && ./bootstrap-vcpkg.sh
The docs for vcpkg install are very clear on how to install it.
Hello @willie ,
Thank you so much for the detailed explanation. I tried it with the following steps with the cpp devcontainer image. For this at least I didn't need to clone the complete vcpkg repository although I did it in manifest mode, It was only needed to install some extra system libraries as given below which I added in the Dockerfile. Perhaps there are more complicated cases on which I am missing out here. Kindly let me know in case of such concerns.
- Added these additional system libraries
autoconf automake libtool m4 autoconf-archivein the Dockerfile & built the cpp image. - Started container from the image & Inside the cpp container created a sample project called test-project with manifest file vcpkg.json & also a small source file main.cpp along with CMakeLists.txt as below.
