From: Jonathan Rajotte Date: Mon, 7 Jun 2021 18:21:06 +0000 (-0400) Subject: Fix: build: libcommon fd-tracker dependency is not available X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=71e2e361e570a4701e06694c6ffeceb3a81a01bd Fix: build: libcommon fd-tracker dependency is not available Observed issue ============== A build configured with: ./configure -disable-bin-lttng --disable-bin-lttng-crash --disable-bin-lttng-sessiond --disable-bin-lttng-relayd Fails at build time with: make[3]: *** No rule to make target '../../src/common/fd-tracker/libfd-tracker.la', needed by 'libcommon.la'. Stop. make[3]: *** Waiting for unfinished jobs.... CC lttng-elf.lo Cause ===== fd-tracker is required by libcommon. This is introduced by commit 8bb66c3cd60938352927ee865759433387324250 [1] Build of libfd-tracker is disabled at the configure level by build_lib_fd_tracker which in turn is enabled/disabled by the --enable/disable-bin-* options. For the observed issue, the --enable-bin-lttng-consumerd alone does not enable the build of libfd-tracker. Solution ======== All dependencies for libcommon are now always built. All bins require libcommon to be present anyway. This patch also fix a problem where the examples under the doc are build even if liblttng-ctl is not built. Known drawbacks ========= None.
