# Bzlmod Migration Status
2+
3+
## Overview
4+
5+
This document tracks the progress of migrating from WORKSPACE to bzlmod (MODULE.bazel) while maintaining compatibility with both systems.
6+
7+
## Current Status
8+
9+
### MODULE.bazel (bzlmod mode) ✅ Mostly Complete
10+
11+
All dependencies have been added to MODULE.bazel with versions aligned as closely as possible with WORKSPACE:
12+
13+
| Dependency | MODULE.bazel Version | WORKSPACE Version | Status |
14+
|------------|---------------------|-------------------|---------|
15+
| abseil-cpp | 20240116.2 | 4a2c63365e (LTS 20240116.0) | ✅ Aligned |
16+
| protobuf | 29.3 | b407e8416e (v29.3) | ✅ Aligned |
17+
| googletest | 1.14.0 | f8d7d77c06 (v1.14.0) | ✅ Aligned |
18+
| google_benchmark | 1.8.3 | 1.8.3 | ✅ Aligned |
19+
| nlohmann_json | 3.11.3 | 3.11.3 | ✅ Aligned |
20+
| googleapis | 0.0.0-20250826-a92cee39 | a92cee399e (Aug 26, 2025) | ✅ Aligned |
21+
| googleapis-cc | 1.0.0 | N/A | ✅ Added for bzlmod |
22+
| proto-converter | 2458ed8 (mmorel-35) | 2458ed8 (mmorel-35) | ✅ Aligned |
23+
| rules_cc | 0.1.1 | 0.1.1 | ✅ Aligned |
24+
25+
### Known Issues
26+
27+
#### 1. Proto-converter Compilation Error in Bzlmod Mode
28+
29+
**Status:** Blocked on upstream fix
30+
31+
**Error:**
32+
```
33+
error: testing if a concept-id is a valid expression; add 'requires' to check satisfaction [-Werror=missing-requires]
34+
```
35+
36+
**Root Cause:** The proto-converter code in commit 2458ed8 may have compilation warnings that are treated as errors. This is a compiler compatibility issue with newer gcc versions.
37+
38+
**Location:** `external/proto-converter~/src/google/protobuf/util/converter/utility.cc`
39+
40+
**Resolution:** This needs to be fixed in the mmorel-35/proto-converter repository, either by:
41+
1. Fixing the code to satisfy the gcc warning
42+
2. Adjusting compiler flags to not treat this warning as an error
43+
3. Updating to a newer commit that has this fix
44+
45+
## Build Instructions
46+
47+
### Bzlmod Mode (Recommended)
48+
49+
```bash
50+
# Build with bzlmod enabled (requires proto-converter fix)
51+
bazel build --enable_bzlmod //src:all
52+
```
53+
54+
### WORKSPACE Mode (Legacy, has compatibility issues)
55+
56+
```bash
57+
# Build with WORKSPACE (currently has protobuf/Bazel 7.6 compatibility issues)
58+
bazel build --noenable_bzlmod //src:all
59+
```
60+
61+
## Next Steps
62+
63+
1. **Priority:** Fix proto-converter compilation error in mmorel-35/proto-converter repository
64+
2. Once proto-converter is fixed, bzlmod mode should work fully
65+
3. Consider deprecating WORKSPACE mode in favor of bzlmod, given the fundamental protobuf version incompatibility
66+
4. Add CI/CD validation for both bzlmod and WORKSPACE modes (once both work)
67+
68+
