Derive runtime templates before setup validation so reruns preserve existing policy. Redact policy JSON by default to avoid exposing owner-local details.

# Building Glove
|
|
|
|
Building proves that the local source compiles; it does not prove that a host
|
|
can enforce managed-session isolation. The boundary and its motivation are in
|
|
[architecture.md](architecture.md) and [threat-model.md](threat-model.md).
|
|
|
|
## Prerequisites
|
|
|
|
- macOS or Linux, CMake **3.28+**, Ninja, Git, and a C++23 compiler/toolchain;
|
|
- Linux: `pkg-config` and `libseccomp` development headers;
|
|
- macOS: Xcode Command Line Tools and a compatible Clang toolchain.
|
|
|
|
On Debian/Ubuntu:
|
|
|
|
```sh
|
|
sudo apt-get update
|
|
sudo apt-get install --yes \
|
|
build-essential clang cmake ninja-build git pkg-config libseccomp-dev
|
|
```
|
|
|
|
`yams` is optional and only enables the macOS integration-test surface.
|
|
|
|
## Build and test
|
|
|
|
`setup.sh` configures, builds, tests, and installs to
|
|
`${GLOVE_INSTALL_PREFIX:-$HOME/.local}`:
|
|
|
|
```sh
|
|
./setup.sh
|
|
```
|
|
|
|
For iteration:
|
|
|
|
```sh
|
|
cmake --preset dev
|
|
cmake --build --preset dev
|
|
ctest --preset dev
|
|
```
|
|
|
|
Run the full local gate before review or release:
|
|
|
|
```sh
|
|
./scripts/preflight.sh
|
|
```
|
|
|
|
## Controlled-source builds
|
|
|
|
Glaze is pinned in `cmake/Dependencies.cmake`. For an offline or controlled
|
|
build, provide the reviewed source explicitly instead of accepting an unpinned
|
|
local checkout:
|
|
|
|
```sh
|
|
cmake --preset release \
|
|
-DFETCHCONTENT_SOURCE_DIR_GLAZE=/absolute/reviewed/glaze-source
|
|
cmake --build --preset release
|
|
ctest --preset release
|
|
```
|
|
|
|
## Managed Linux sessions
|
|
|
|
A managed-session host also needs cgroup v2 (`cpu`, `memory`, `pids`), user and
|
|
mount namespaces, mount support, seccomp, and systemd delegation. Those
|
|
requirements exist because Glove must enforce resource and filesystem limits,
|
|
not merely start a process. See [host-setup.md](host-setup.md) for the
|
|
owner-local workflow and [session-policy.md](session-policy.md) for the policy
|
|
contract.
|
|
|
|
The privileged Docker command is only a test environment; it is not production
|
|
isolation evidence:
|
|
|
|
```sh
|
|
docker build -f dockerfiles/Dockerfile.linux -t glove-linux .
|
|
docker run --rm --privileged --security-opt seccomp=unconfined glove-linux
|
|
```
