[gentoo-user] Cryptic output from emerge

[gentoo-user] Cryptic output from emerge

[meino.cramer]

Hi

After an

    emerge --color=n --newuse --update --tree --deep world -vp

I got this output. What does the line with "cxx?" want say to me?



    These are the packages that would be merged, in reverse order:

    Calculating dependencies /

    !!! Problem resolving dependencies for dev-libs/beecrypt from @selected                                                                                                                                                                     ... done!

    !!! The ebuild selected to satisfy "dev-libs/beecrypt" has unmet requirements.
    - dev-libs/beecrypt-4.2.1::gentoo USE="cxx (multilib) -doc -java -python -static-libs -threads"

    The following REQUIRED_USE flag constraints are unsatisfied:
        cxx? ( threads )

    (dependency required by "@selected" [set])
    (dependency required by "@world" [argument])
    [1]    19260 exit 1     emerge --color=n --newuse --update --tree --deep world -vp

Thank you very much in advance for a help...

Best regards,

It says you need to enable threads if you want c++ support. (If cxx
useflag is present, check for threads useflag).

I have seen this message yesterday.
Just add "dev-libs/beecrypt threads" to /etc/portage/package.use
and you'll be fine...

Thanks a lot for your help! I was unsure about this cause of
the question mark after cxx...

It means that if you have "USE=cxx" set for dev-libs/beecrypt, then you
must also have "USE=threads" set for the package. Note that it only
applies to this package, it doesn't mean you must set the flags
globally.

The emerge output shows that you indeed have not met these
requirements. You must either unset cxx or set threads.

It's a conditional, it basically means

if USE contains cxx then USE must contain threads.
