* GNUmakefile: Simplify the $SHELLAlejandro Colomar2024-04-16-3/+2
| | | | | | | | | | | | nixpkgs does not provide /usr/bin/env, so they had to work around it by specifying just env. Since make(1) accepts program names instead of paths, we can as well use bash directly, which is simpler.

* share/mk/: build-book, build-man, install-man: Specify version and dateAlejandro Colomar2024-03-21-3/+2
| | | | | | | | | | | | | | Each page has its own date. Add new 'build-man' target, which stamps the date and version in the pages (in $builddir, not the source ones). Build-system internal stuff: $CURDIR will be used for the build system, while $srcdir will be used for the project root of the repository. This helps use this build system in other projects.

* GNUmakefile: Remove helpAlejandro Colomar2024-03-19-182/+0
| | | | | | | | | | | | | | | | | It gets out of date easily, and it's always more accurate to actually read the makefiles, or run a command that parses them for us. In the case of .PHONY targets, or available variables, here are two commands that can help: $ make nothing -p \ | grep '^\.PHONY:' \ | tr ' ' '\n' \ | grep -v '^\.PHONY:' \ | sort; $ grep -rho '^[^[:space:]].*=' GNUmakefile share/mk/configure/; Signed-off-by: Alejandro Colomar <alx@kernel.org>

* share/mk/: dist: FORCE regeneration of version file if necessaryAlejandro Colomar2024-02-25-0/+1
| | | | | | | | | | | If any of $DISTVERSION, $DISTNAME, or $DISTDATE have changed since the last 'make dist', force regeneration of the version file, even if it wouldn't change due to normal dependencies. This makes sure that the tarball has correct values. It doesn't need to depend on all $DISTFILES. Signed-off-by: Alejandro Colomar <alx@kernel.org>
* share/mk/: Use a variable to prefix recursive make(1) outputAlejandro Colomar2024-02-25-154/+157
| | | | | | | | | Piping the output to sed(1) didn't behave well with -Orecurse. Using a variable behaves well, keeping output synchronized. The length of the variable name is specific, so that `$(INFO_)` uses exactly 8 characters, a tab. Signed-off-by: Alejandro Colomar <alx@kernel.org>

* *.mk: SHELL, .SHELLFLAGS: Fix the SHELLAlejandro Colomar2023-09-03-1/+2
| | | | | | | | | | | - Arguments to the shell need to go in .SHELLFLAGS. - env(1) needs -S to split arguments to it. Maybe it's not necessary in make(1), though; not sure. - The scripts are passed to the shell as arguments, not via stdin; thus, we need -c.

* *.mk: Remove 'V' variableAlejandro Colomar2023-08-28-2/+2
| | | | | | | | | | | | | | GNU Make (since version 4.4) provides the same functionality with `--debug=print`. Remove this custom variable, which is now redundant with the new option. - Define .SILENT: unconditionally. - Define HIDE_ERR unconditionally, and let the user redefine it to an empty string.

* GNUmakefile: mv Makefile GNUmakefileAlejandro Colomar2023-08-17-0/+235
We require GNU Make. Let's make it explicit by using the appropriate GNU Make makefile name. This will avoid users innocently running other make(1) implementations and be confused by errors, as happened with Ingo Schwarze long ago.
