Current libbpf Makefile does not contain the help command, which is inconvenient to use. Similar to the Makefile help command of the perf, a help command is provided to list the commands supported by libbpf make and the functions of the commands. Signed-off-by: Xin Liu <liuxin350@xxxxxxxxxx> --- v2: Simplified display. Some unused commands are displayed in the help command. v1: https://lore.kernel.org/bpf/20221129074235.116969-1-liuxin350@xxxxxxxxxx/ tools/lib/bpf/Makefile | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/tools/lib/bpf/Makefile b/tools/lib/bpf/Makefile index 4c904ef0b47e..ae523e4cce05 100644 --- a/tools/lib/bpf/Makefile +++ b/tools/lib/bpf/Makefile @@ -286,3 +286,22 @@ tags: # Delete partially updated (corrupted) files on error .DELETE_ON_ERROR: + +help: + @echo 'libbpf default targets:' + @echo ' HINT: use "V=1" to enable verbose build' + @echo ' all - build librarys and pkgconfig' + @echo '' + @echo 'libbpf install targets:' + @echo ' HINT: use "prefix"(default "/usr/local") or "DESTDIR"(default "/")' + @echo ' to install to a particular path like "make prefix=/usr/local install"' + @echo ' install - build and install all headers, librarys and pkgconfig' + @echo ' install_headers - install only headers to include/bpf' + @echo '' + @echo 'libbpf make targets:' + @echo ' tags - use ctags to make tag information for source browsing' + @echo ' cscope - use cscope to make interactive browsing database' + @echo '' + @echo 'libbpf maintainer targets:' + @echo ' clean - remove all generated files' + @echo ' check - check abi and version info' -- 2.33.0
