LTTng » LTTng-tools

When compiling lttng-tools the build fails because of a missing dependency (-lnuma):

Making all in lttng-consumerd
make[3]: Entering directory '/home/erica/lttng-tools/src/bin/lttng-consumerd'
  CXXLD    lttng-consumerd
/usr/bin/ld: cannot find -lnuma: No such file or directory
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:657: lttng-consumerd] Error 1
make[3]: Leaving directory '/home/erica/lttng-tools/src/bin/lttng-consumerd'
make[2]: *** [Makefile:587: all-recursive] Error 1
make[2]: Leaving directory '/home/erica/lttng-tools/src/bin'
make[1]: *** [Makefile:580: all-recursive] Error 1
make[1]: Leaving directory '/home/erica/lttng-tools/src'
make: *** [Makefile:695: all-recursive] Error 1

This is unexpected since the configuration step was successful (which, based on my understanding, should have caught any missing dependencies).

Tools version¶

lttng-tools master branch from this commit:

7d5802d16 tests: Add path check to prevent incorrect redirection

plus these changes (patchset 52). So not an official release.

Other context bits¶

Additional context that may or may not be useful.

• lttng-ust and userspace-rcu are installed from source in `~/install-dir`
• The `libnuma1` package is installed, but the missing dependency `libnuma-dev` is not. It is apparently unusual that configuration would succeed with `libnuma-dev` missing.
