Dear Alexander Holler,
In message 4D2BB9AC.1040504@ahsoftware.de you wrote:
On the other hand, that would require changes to many files, and the gcc __VERSION__ string is pretty long on some systems, which may cause additional problems.
Hmm, here it includes only "4.5.2", the plain version and not the vendor version. Therfore I was happy with that, because the vendor version would be too long to display at startup.
Well, what I see is for example "4.5.1 20100924 (Red Hat 4.5.1-4)" with the native GCC on Fedora 14; some other tool chains provide similar long results.
I also doubt that we need this information with each boot message (where it just slows down booting).
Hmm, I haven't counted the time needed to display additional 9 characters, but displaying the version at startup is handy for "screen
It's about 1 millisecond at 115 kbps, or 10 milliseconds at 9600 ;-)
dumps" (e.g. stuff pasted by people with problems).
I think we're already printing way too muc information- and still people don't include even the most vital information like which version of U-Boot they are running.
Would it not be sufficient to add this to the code of do_version() so we can get this information when we want it, i. e. when running the "version" command?
I would like that. But as you said, my intention was really only because of the current problems with gcc for arm.
So will you prepare a patch? [TIA!]
Besides that, I would found it handy to see the used compiler for u-boot's where I don't have the source by hand, e.g. those already found on boards. But that might be because I'm curious by default. ;)
Well, eventually we should print more than __VERSION__, then. Becasue if you see "4.4.1" - what does it tell you? You don't see that this is the Sourcery G++ Lite 2010q1-202 version of GCC, or that ""4.5.0 20100729 (prerelease)" is a specific Poky release?
Anyway, I would found it a nice feature, at startup or when running the version command, but both aren't a must.
I think it would be a really useful extension to the version command. Looking forwad to seeing your patch.
Best regards,
Wolfgang Denk
