Description Patrick 2008-10-09 08:30:51 UTC

I just built net-mail/dovecot-1.1.4-r1 for a few VServers, and on some of them starting dovecot failed with the following message:

/usr/sbin/dovecot: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory

I guess this is because on the build machine libcap.so.1 is available, but on the VServers it is not. I built dovecot on the VServers where it wouldn't start, and now it runs fine there - but I fear this will happen again next time.

What to do about it? Introduce a USE flag?

Reproducible: Always

There's the caps USE flag to control this. It's one of those USE flags you want to set globally and that will infect many libraries.

Comment 2 Patrick 2008-10-10 05:16:08 UTC

Thanks, didn't know that... so this bug report is invalid, I guess.

Comment 3 Sander Toonen 2008-10-11 10:35:04 UTC

I have the same problem, but the caps useflag is set globally in /etc/make.conf. Just upgraded to net-mail/dovecot-1.1.4-r1 and now, when i restart dovecot, i get the message: 

/usr/sbin/dovecot: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory

Also, updating world deep with new use flags does not affect anything so i assume that caps is compiled in already.

well, dovecot itself would need to support USE=caps ...

Fixed in 1.1.7-r1.
dovecot now unconditionally depends on sys-libs/libcap as
configure does not support any --with/enable-capabilities
switch and I'm not going to patch configure for that.
If you don't like that, ask upstream to change configure :)
