Error when trying to configure a cmake build for static linking #1283

Git commit reference
a1a32d2 (v10.0.32)

Describe the bug
I'm attempting to build my bot with dpp statically linked. This is the FetchContent config for dpp that I'm using:

include(FetchContent)

# Fetch and build DPP.
set(BUILD_SHARED_LIBS OFF)
set(DPP_CORO ON)

FetchContent_Declare(
    dpp
    GIT_REPOSITORY https://github.com/brainboxdotcc/DPP.git
    GIT_TAG v10.0.32
)

FetchContent_MakeAvailable(dpp)

target_link_libraries(
    ${PROJECT_NAME}
    PRIVATE
    dpp
)

And here's the output of running the configure command for the build:

Expected behavior
Cmake configures the build without errors.

Screenshots
N/A

System Details:

OS: Ubuntu 24.04
Discord Client used for testing: N/A

Additional context
The above config works fine for a shared lib build.

wheres the rest of the cmake output? i dont see any error?

@braindigitalis the entire output is all there. The errors are at the bottom:

do you have vcpkg installed on your system?

DPP is trying to enable building using vcpkg which is not working on 10.0.32 which is why it isnt released there yet.
Add the following build rule to your cmake and try again: -DDPP_NO_VCPKG=ON
let me know if this fixes it!

davidscholberg · 2024-10-17T00:07:57Z

@braindigitalis unfortunately the same errors still occur:

I don't think I have vcpkg on here (certainly never used it).

braindigitalis · 2024-10-17T00:22:54Z

i think the problem is with static linking in general. I am not sure of the fix right now, but we'll come up with something. Until then are you able to use dynamic linking as a workaround?

davidscholberg · 2024-10-17T00:45:05Z

Yes dynamic linking works fine, appreciate you looking into it!

davidscholberg · 2024-10-17T00:49:22Z

I think this stackoverflow post may be relevant, but I haven't looked deeply enough at the dpp cmake config to confirm it: https://stackoverflow.com/questions/40183810/why-does-cmake-export-require-static-libraries-used-to-build-a-shared-library

braindigitalis · 2024-10-18T13:06:29Z

There is a PR #1290 which should fix this once it makes its way to master.
