fe4d0d5d - rtla/Makefile: Properly handle dependencies

Fri, 29 Apr 2022 14:54:58 +0000

rtla/Makefile: Properly handle dependenciesLinus had a problem compiling RTLA, saying:"[...] I wish the tracing tools would do a bit more packagechecking and helpful error messages too, rather than justfail with: fatal error: tracefs.h: No such file or directory"Which is indeed not a helpful message. Update the Makefile, addingproper checks for the dependencies, with useful information abouthow to resolve possible problems.For example, the previous error is now reported as: $ make ******************************************** ** NOTICE: libtracefs version 1.3 or higher not found ** ** Consider installing the latest libtracefs from your ** distribution, e.g., 'dnf install libtracefs' on Fedora, ** or from source: ** ** https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/ ** ********************************************These messages are inspired by the ones used on trace-cmd, as suggestedby Stevel Rostedt.Link: https://lore.kernel.org/r/CAHk-=whxmA86E=csNv76DuxX_wYsg8mW15oUs3XTabu2Yc80yw@mail.gmail.com/Changes from V1: - Moved the rst2man check to the install phase (when it is used). - Removed the procps-ng lib check [1] as it is being removed.[1] a0f9f8c1030c66305c9b921057c3d483064d5529.1651220820.git.bristot@kernel.orgLink: https://lkml.kernel.org/r/3f1fac776c37e4b67c876a94e5a0e45ed022ff3d.1651238057.git.bristot@kernel.orgCc: Ingo Molnar Cc: Andrew Morton Reported-by: Linus Torvalds Suggested-by: Steven Rostedt Signed-off-by: Daniel Bristot de Oliveira Signed-off-by: Steven Rostedt (Google) List of files: /linux-6.15/Documentation/tools/rtla/Makefile

rtla: Add DocumentationAdds the basis for rtla documentation. This patch alsoincludes the rtla(1) man page.As suggested by Jonathan Corbet, we are placing these manpages at Documentation/tools/rtla, using rst format. Itis not linked to the official documentation, though.The Makefile is based on bpftool's Documentation one.Link: https://lkml.kernel.org/r/5f510f3e962fc0cd531c43f5a815544dd720c3f2.1639158831.git.bristot@kernel.orgCc: Tao Zhou Cc: Ingo Molnar Cc: Tom Zanussi Cc: Masami Hiramatsu Cc: Juri Lelli Cc: Clark Williams Cc: John Kacur Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: Sebastian Andrzej Siewior Cc: Daniel Bristot de Oliveira Cc: linux-rt-users@vger.kernel.orgCc: linux-trace-devel@vger.kernel.orgCc: linux-kernel@vger.kernel.orgSuggested-by: Steven Rostedt Suggested-by: Jonathan Corbet Signed-off-by: Daniel Bristot de Oliveira Signed-off-by: Steven Rostedt List of files: /linux-6.15/Documentation/tools/rtla/Makefile
