rtla started to only link parts of the tools library. It now misses the
ctype information used by all the related string operations. Just add
another single file to make it build again.

RTLA: Real-Time Linux Analysis tools The rtla meta-tool includes a set of commands that aims to analyze the real-time properties of Linux. Instead of testing Linux as a black box, rtla leverages kernel tracing capabilities to provide precise information about the properties and root causes of unexpected results. Installing RTLA RTLA depends on the following libraries and tools: - libtracefs - libtraceevent - libcpupower (optional, for --deepest-idle-state) - libcheck (optional, for unit tests) For BPF sample collection support, the following extra dependencies are required: - libbpf 1.0.0 or later - bpftool with skeleton support - clang with BPF CO-RE support It also depends on python3-docutils to compile man pages. For development, we suggest the following steps for compiling rtla: $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git $ cd libtraceevent/ $ make $ sudo make install $ cd .. $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git $ cd libtracefs/ $ make $ sudo make install $ cd .. $ cd $libcpupower_src $ make $ sudo make install $ cd $rtla_src $ make $ sudo make install Running tests RTLA has two test suites: a runtime test suite and a unit test suite. The runtime test suite is available as "make check" (root required) and has the following dependencies, in addition to RTLA build dependencies: - Perl - Test::Harness (libtest-harness-perl on Debian/Ubuntu, perl-Test-Harness on Fedora/RHEL) - bash - coreutils - ldd - util-linux - procps(-ng) - bpftool (if rtla is built against libbpf) as well as the following required system configuration: - CONFIG_OSNOISE_TRACER=y - CONFIG_TIMERLAT_TRACER=y - tracefs mounted and readable at /sys/kernel/tracing The unit test suite is available as "make unit-tests" and has the following dependencies: - libcheck Unlike the runtime test suite, root is not required to run unit tests, nor is a tracefs/osnoise/timerlat-capable kernel required. For further information, please refer to the rtla man page.
