# frontend/apiserver — Go REST API server with CGO backend integration.

|

# CGO is required for two reasons:
|
|
# 1. pam_linux.go: dlopen/dlsym for PAM (handled by -ldl in the source file)
|
|
# 2. backend/clib.go: libxce C client library for IPC with the controller
|
|
#
|
|
# Include/link flags for libxce and its transitive deps are gathered from
|
|
# pkg-config and injected into CGO_CFLAGS/CGO_LDFLAGS so the go_build script
|
|
# can substitute path placeholders before invoking go build.
