This series enables building this tool alongside other userspace tools bundled with the Linux kernel (known in buildroot as linux-tools). In order to add linux-tool-tmon, we need to first stop relying on alphabetical sorting of the linux-tool*.mk files. Currently, the build system relies on linux-tool-*.mk files (i.e. the sub-makefiles) to be sorted alphabetically such that linux-tools.mk (the main makefile for linux-tools) will come last, therefore ensuring that the sub-makefiles are included before the main makefile. So far, this assumption has held true. Unfortunately, linux-tool-tmon.mk breaks it. Sorted in the C locale, linux-tool-tmon.mk comes after linux-tools.mk. To ensure that the inclusion order remains correct, the logic to include the linux-tool*mk has been modified.

The proposal is to move all the linux-tool-*.mk files to subdirectories of package/linux-tools, and include them from the linux-tool.mk file at the appropriate place. This is more in-line with how we do it for other packages, e.g. qt5 or barebox. Ideally, the Config.in would also be split up into the individual subpackages. Could you prepare a patch for that?

Hm, Yann tells me that make always uses the C locale for sorting. So why does it fail for you? The C locale for sure sorts correctly. Also, the only thing that is sensitive to the order in this case is LINUX_TOOLS_DEPENDENCIES. So you would miss the dependency on ncurses if it is in the wrong order. Is that what happens for you? Could you tell us what error you get?

Looks like the build is actually succeeding for me now. Not sure what happened originally when it bailed the way it did. My build must have been in a weird state. My apologies for the false alarm. I successfully built arm and arm64. This means, we don't need patch 1/2 after all. That said, and while I am a complete buildroot newbie, I do like the suggestion of creating sub-directories for the tools and including the makefiles from linux-tools.mk rather than relying on alphabetical sorting.

Unless you also expected that the big Config.in file be split too? I would argue against, because its fate is already a bit special: it is not sourced from package/Config.in but from linux/Config.in. and I would prefer we avoid a bit more complexity...

Yeah, I was wondering about that myself, actually. I do agree that several directories containing only one file each don't seem all that desirable. I'll see if I can get everything to work with just a single sub-directory. Regards, -Markus ^ permalink raw reply [flat|nested] 22+ messages in thread

I think I may need some help. I started implementing the suggested solution, but I have run into some unexpected problems. Specifically, if I move the linux-tool-*.mk files into their own sub-directory, all linux-tools related targets disappear. It won't build any linux-tools during a regular run of 'make' and it will actually say "No rule..." when explicitly asked to build linux-tools: $ make linux-tools umask 0022 && make -C /home/mmayer/Development/buildroot O=/home/mmayer/Development/output/arm64/. linux-tools make[1]: *** No rule to make target 'linux-tools'. Stop. Makefile:16: recipe for target '_all' failed make: *** [_all] Error 2 Here's what I have done: (mmayer at lbrmn-mmayer) ~/Development/buildroot$ l package/linux-tools/ total 84 drwxrwxr-x 3 mmayer mmayer 4096 Jul 13 11:38 . drwxrwxr-x 1843 mmayer mmayer 65536 Jul 10 12:28 .. -rw-rw-r-- 1 mmayer mmayer 2577 Jul 10 11:02 Config.in -rw-rw-r-- 1 mmayer mmayer 2049 Jul 13 11:20 linux-tools.mk drwxrwxr-x 2 mmayer mmayer 4096 Jul 13 11:20 tools (mmayer at lbrmn-mmayer) ~/Development/buildroot$ l package/linux-tools/tools/ total 28 drwxrwxr-x 2 mmayer mmayer 4096 Jul 13 11:20 . drwxrwxr-x 3 mmayer mmayer 4096 Jul 13 11:38 .. -rw-rw-r-- 1 mmayer mmayer 1061 Jul 10 13:04 linux-tool-cpupower.mk -rw-rw-r-- 1 mmayer mmayer 753 Jul 10 15:27 linux-tool-gpio.mk -rw-rw-r-- 1 mmayer mmayer 730 Jul 10 13:04 linux-tool-iio.mk -rw-rw-r-- 1 mmayer mmayer 4015 Jul 10 13:04 linux-tool-perf.mk -rw-rw-r-- 1 mmayer mmayer 1469 Jul 10 13:04 linux-tool-selftests.mk linux-tools.mk gains this new line at the very beginning: include $(sort $(wildcard package/linux-tools/tools/*.mk)) This results in the aforementioned non-build of linux-tools. Though when I look at all the variables, they are set properly. LINUX_TOOLS, LINUX_TOOLS_DEPENDENCIES, etc. all have the proper values. Everything *looks* like it should work, but somehow the linux-tools targets do not exist, so it doesn't actually work. I tried something else for test-purposes. If I don't put the linux-tool-*.mk into their separate sub-directory and, instead, simply change their extension (so they don't match the *.mk pattern in the main Makefile), it all starts to work perfectly. $ l package/linux-tools/ total 104 drwxrwxr-x 3 mmayer mmayer 4096 Jul 13 11:46 . drwxrwxr-x 1843 mmayer mmayer 65536 Jul 10 12:28 .. -rw-rw-r-- 1 mmayer mmayer 2577 Jul 10 11:02 Config.in -rw-rw-r-- 1 mmayer mmayer 1061 Jul 10 13:04 linux-tool-cpupower.xmk -rw-rw-r-- 1 mmayer mmayer 753 Jul 10 15:27 linux-tool-gpio.xmk -rw-rw-r-- 1 mmayer mmayer 730 Jul 10 13:04 linux-tool-iio.xmk -rw-rw-r-- 1 mmayer mmayer 4015 Jul 10 13:04 linux-tool-perf.xmk -rw-rw-r-- 1 mmayer mmayer 1469 Jul 10 13:04 linux-tool-selftests.xmk -rw-rw-r-- 1 mmayer mmayer 2043 Jul 13 11:46 linux-tools.mk $ grep ^include package/linux-tools/linux-tools.mk include $(sort $(wildcard package/linux-tools/*.xmk)) So, now, everything is at the package/linux-tools level again. The sub makefiles simply have the extension .xmk. This also ensures they don't get picked up by the main Makefile, but by linux-tools.mk. This setup works flawlessly. As far as I can tell, it should make no difference if the sub-makefiles are being included from package/linux-tools or package/linux-tools/tools. All the make variables are being set to the same values in both cases. Somehow, however, it doesn't generate the proper target list in the sub-directory case, but does the right thing if it's all in the same directory. Does anybody have any pointers as to why this might be and what to do about it? Thanks, -Markus ^ permalink raw reply [flat|nested] 22+ messages in thread

Rename the 'tools' directory to 'linux-tools' and try again. [--SNIP--] > Does anybody have any pointers as to why this might be and what to do about it? Yes, this is becasue the last line in package/linux-tools/linux-tools.mk is calling to the generic-package infrastructure. In turn, that line will at some place evaluate the $(pkgname) macro. pkgname is defined as thus: pkgname = $(lastword $(subst /, ,$(pkgdir))) And in turn, pkgdir is defined as: pkgdir = $(dir $(lastword $(MAKEFILE_LIST))) So, what this does is get the filename of the last included makefile, keep the directopry part of it, and then extract the last component of that, to get the package name. By moving the tools to a sub-directory named 'tools' make that the last makefile parsed is in that sub-directory by the time pkgname is called, and it then gets 'tools' instead of 'linux-tools'. We have a similar situation in linux/linux.mk, see line 425 where we have an explanation about this: 423 # Include all our extensions. 424 # 425 # Note: our package infrastructure uses the full-path of the last-scanned 426 # Makefile to determine what package we're currently defining, using the 427 # last directory component in the path. As such, including other Makefile, 428 # like below, before we call one of the *-package macro is usally not 429 # working. 430 # However, since the files we include here are in the same directory as 431 # the current Makefile, we are OK. But this is a hard requirement: files 432 # included here *must* be in the same directory! 433 include $(sort $(wildcard linux/linux-ext-*.mk)) So I would argue against the sub-directory, but in favour of renaming the files. Except that is not necessary, is it? IIRC, you confirmed that this was in fact not a problem, right? So, rather than try to fix a problem that does not exist, using fragile heuristics, I would recommend we keep the status-quo. Regards, Yann E.

It was my understanding that the alphabetical sorting of linux-tools has been considered to be not really all that desirable and that a "once and for all" solution that does away with this requirement would be welcomed. That's why I looked into these changes. I'll leave the decision to the maintainers as to whether this should be changed (either using a sub-directory or an file extension other than .mk) or if it is preferable to keep the alphabetical sorting. My personal take is that relying on alphabetical sorting is more fragile than the alternate solution, but it is up to you guys.

I don't have a very strong opinion on this. To me, it would be fine to have linux-tools.mk and then the per-tool files called linux-tool-<foo>.mk.in or something like that.
