Runs build flows for the canonical Fyne shell and module commands on this Go 1.25 monorepo. Use when building, packaging, or debugging build failures in cmd/fecim-lattice-tools or module GUI commands.
fecim-builder
See tools/fecim-skills/_shared/fecim-context.md (Build target matrix) for the canonical CGO/entry-point mapping.
Workflow
Identify the target — ask the user if unclear:
Canonical Fyne shell: cmd/fecim-lattice-tools
Set the build environment:
Canonical: export CGO_ENABLED=0.
Run the build:
Canonical single-binary: CGO_ENABLED=0 go build -o fecim-lattice-tools ./cmd/fecim-lattice-tools
Canonical launch: ./launch.sh
Whole repo: go build ./...
Preflight first: verify repo path, go, git, and rg/fallback using _shared/fecim-context.md.
On failure, triage:
Symptom
Cause
Fix
fatal error: GL/gl.h: No such file
Missing OpenGL headers
Report blocker with command output; operator/admin installs packages.
cannot find -lvulkan
Vulkan loader missing
Report blocker for legacy/Vulkan path; optional dep may be omitted when not required.
gcc not found
CGO toolchain missing
Report blocker with command -v gcc evidence; operator/admin installs packages.
package github.com/Fyne: cannot find module
Fyne import in non-shell pkg
UI-boundary violation; move logic to shared/viewmodel/ per AGENTS.md
Verify:
Binary exists and is executable.
For the canonical app, confirm CGO_ENABLED=0 was respected (go env CGO_ENABLED should print 0 in the same shell).
Verification
Input: "Build the legacy GUI."
Input: "Build the canonical shell." with missing libvulkan-dev.
Expected: succeeds since libvulkan is optional, OR triages with the table above.
TDD
Build invocations are observation, not behavior change — TDD: N/A. Any code change discovered during triage triggers the project's TDD hard-rule. See tools/fecim-skills/_shared/tdd-evidence-template.md.
