I am new to Buildroot and I am trying to figure out how to update genimage to newer version in Buildroot. I am currently on version 14 and I would like to update to version 15 of genimage tool.

Can anyone please let me know how to upgrade to newer versions of tools in Buildroot?

I found the PATCH file to bump to version 15 here : genimage But I am not sure how to apply this Patch file in Buildroot.

Thanks in advance.

P.S: I am using Buildroot 2021.11.2.

There's a combinatorics puzzle (as mentioned in Mathematics From the Birth of Numbers by Jan Gullberg) where if you line up fifteen members from two categories each (e.g. fifteen of category 0 and fifteen of category 1 for a total of 30 elements) mixed up in a certain order, then if you continuously go along this line in a circular fashion (i.e. wrapping around back to the start when you reach the end, continuing counting as you go) throwing out every ninth element, you'll eventually have just the elements of the one "favored" (1) category

Lets say I have a string "lore epsum dimsum ${ITEM_NAME} wonton kimchi".

I have created a regex that can extract ${ITEM_NAME} from anywhere in the string. That regex is, .{(.*.*)}.

How can I customize this regex to extract just the string between ${} which is ITEM_NAME?

I can see lots of copied lore that functions registered with the .init_array section have the command-line arguments argc and argv, like main(), but I am failing to find any actual published documentation online that confirms that this is the case.

Yes, for clarity, the function itself is not "declared in" the .init_array, but a pointer to the function is declared there, "registering" the function, and it is called by some iterator during start-up. Question remains: show me some documentation for the argument list passed in by that iterator.

My intent is to change these arguments from a dynamic library in a subtle but generally safe way, so I want to find the "real deal" in memory - not from /proc/self/.

Even my favoured Oracle ( docs.oracle.com/cd/E23824_01/html/819-0690/chapter3-8.html ) only mentions that the functions get called, but no promise of what arguments there might be. Same with the elf and gcc documentation, as far as I can see.

In the land of C/C++ UB paranoia, Ideally I need some certainty that this is documented behaviour before I go ahead with it? Does it exist? Can it be implied in some way?

Summary of comments/answers so-far:

At least for GNU libc, a relevant change occurred with this patch: BZ #974. https://sourceware.org/pipermail/libc-alpha/2005-July/019240.html (It is mentioned in glibc's ChangeLog.old/ChangeLog.16 entry 2005-04-13 H.J. Lu.) – Ian Abbott

To me, this demonstrates that the glbc maintainers were aware of the requirement to pass argc/argv/env - that it is not accidental - and extended it to main exe registrations. It also tells us that it was working for dynamic libraries prior to that date.

It is an interesting question whether this binds other libc implementers to follow the pattern.

I need to filter a main array using another array. But the filter array will only contain a few fields or several.

Im writing a program that needs to get the path of all the directories with JAVA files on it, recursively, for example:
