how to identify what version of gcc was used?

[kcy29581]

Hi all,

I bet this is easy...

How can identify which version of gcc compiled an application?

Thanks

[ghostdog74]

what did the man page say.. don't be lazy. read the man page

[kcy29581]

...

I do not have access to the man page; I'm at work and using MSYS. Google hasn't yielded anything yet either. I do not have access to my Linux PC at the moment. I'll try gcc's site now.

So, please, if you know the command, what is it?

its as simple as typing "how to find gcc version" in google. The first return result says it all. Now that isn't hard at all right?

if you are talking about:
gcc -v then I implore you to read the question before answering, especially when you are "trying" to patronise people.
The question was:

To put it even simply for you to understand, someone compiled an application, I need to verify they used a specific version of gcc; how do I do that?

As far as I know normally there is no information about the compiler version added to executables. You can use "ldd" to check the libraries linked, though. The command "file" also outputs some helpful info on binaries, like the architecture it was compiled for.

Thanks fct.

Unfortunately neither of those two commands appear to work on MSYS. I'll have to wait until tomorrow when my Linux development PC is set up.

It's crazy though, we have to verify gcc versions for executables, but they don't tell us how. Typical work! :)

If they don't know how, and you don't know, how will they know you're not making it up? :D

I work for a games development company, and the game we're working on will end up going to Sony, and they know how to check this! But knowing them, they'll only tell us AFTER they fail the game. :D

Have you tried


aptitude show gcc

[kcy29581]

aptitude show gcc

I'll give that a go tomorrow, thanks.

Can you recompile?

[kcy29581]

Can you recompile?

I work on the testing side so I don't have the source code. I'm here to make sure the development teams don't screw up. If I asked them for verification, I know they'd just say "it's ok" without actually checking! :rolleyes:

I'll give that a go tomorrow, thanks.

Plz tell :) Pleasure helping :D Hope that helps :D

even if its so, then change your search term ("how to determine compiler version")... here's the first result


strings - yourapplication | grep GCC

you can try that. btw, i don't patronise people. i just want them to be self sufficient.

sorry ghostdog74, but the tone of your replies was very similar to all the replies I've had in the office: RTFM; if I had the manual or knew which manual had the answer then I'd be fine reading away. I try to use the forums only as a last resort.

Thanks for the suggestion, I'll give it a shot.

[kcy29581]

SOLVED!

Thanks ghostdog74! You :guitar:

The command you suggested works like a charm!

first of all, glad that it worked for you.
second, i did not give you the answer. Google did. :)

Yeah, but Google gave it via you! :)

that just shows what version of gcc is available from the repositories. that does not answer the question of what version of gcc was used to compile some particular application.

That looks interesting... I will try that...
