# vcpkg: Troubleshooting & Dependency Lifecycle
|
|
|
|
Reference for the `vcpkg` skill. Use this when a user encounters vcpkg build failures, package-not-found errors, needs to read build logs, or manages the dependency lifecycle (removing, changing features, replacing libraries, cleaning the cache).
|
|
|
|
## Reading vcpkg Build Logs
|
|
|
|
Build logs are stored at:
|
|
```
|
|
<vcpkg-root>/buildtrees/<port-name>/
|
|
```
|
|
|
|
Key log files:
|
|
- `config-<triplet>-out.log` — CMake configure output
|
|
- `build-<triplet>-<dbg|rel>-<out|err>.log` — common build logs
|
|
- `install-<triplet>-<dbg|rel>-<out|err>.log` — common install logs
|
|
|
|
Exact names vary by port and build helper; use the path vcpkg prints for the failing command.
|
|
|
|
When a build fails, vcpkg prints the path to the relevant log. Start with the `-err.log` file for the failing step.

## Resolving package-not-found After Install
|
|
|
|
If CMake says `Could not find a package configuration file provided by "X"`:
|
|
|
|
1. **Check toolchain file** — ensure `-DCMAKE_TOOLCHAIN_FILE=<vcpkg-root>/scripts/buildsystems/vcpkg.cmake` is set
|
|
2. **Check triplet match** — the installed triplet must match your build architecture
|
|
3. **Check package name** — vcpkg port names may differ from CMake package names (e.g., port `nlohmann-json` → `find_package(nlohmann_json)`)
|
|
4. **Check installed list** — run `vcpkg list` to confirm the package is actually installed
|
|
5. **Clear CMake cache** — delete `CMakeCache.txt` and reconfigure
|
|

## Dependency Lifecycle
|
|
|
|
### Removing a Library
|
|
|
|
1. Remove it from `vcpkg.json` → `"dependencies"` array
|
|
2. Run `vcpkg install` to reconcile (manifest mode auto-removes unused packages)
|
|
|
|
In classic mode:
|
|
```console
|
|
vcpkg remove boost-regex
|
|
vcpkg remove boost-regex --recurse # also removes dependents
|
|
```
|
|
|
|
### Changing Features on an Installed Library
|
|
|
|
Update the features in `vcpkg.json`:
|
|
```json
|
|
{
|
|
"dependencies": [
|
|
{
|
|
"name": "curl",
|
|
"features": ["ssl", "ssh"]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
Then run `vcpkg install` — vcpkg will detect the feature change and rebuild.
|
|
|
|
In classic mode:
|
|
```console
|
|
vcpkg install curl[ssl,ssh] --recurse # permits rebuilding with the new feature set
|
|
```
|
|
|
|
### Replacing One Library with Another
|
|
|
|
1. Remove the old library from `vcpkg.json`
|
|
2. Add the new library to `vcpkg.json`
|
|
3. Run `vcpkg install` to reconcile
|
|
4. Update your source code: change `#include` directives, `find_package()` calls, and `target_link_libraries()` in CMakeLists.txt
|
|
|
|
### Cleaning the vcpkg Cache
|
|
|
|
```powershell
|
|
# Remove all package build artifacts
|
|
vcpkg x-clean
|
|
|
|
# Optional: remove local cache/install directories
|
|
Remove-Item -Recurse -Force <vcpkg-root>\buildtrees,<vcpkg-root>\downloads,<vcpkg-root>\installed,.\vcpkg_installed
|
|
```
|
|
|
|
```bash
|
|
# Remove all package build artifacts
|
|
vcpkg x-clean
|
|
|
|
# Optional: remove local cache/install directories
|
|
rm -rf <vcpkg-root>/buildtrees <vcpkg-root>/downloads <vcpkg-root>/installed ./vcpkg_installed
|
|
```
