Hello, Gentoo.
For the past couple of days, after $ emerge --sync, I've tried
$ emerge -auND @world
.. It has come back very quickly with the error message:
#########################################################################
!!! The ebuild selected to satisfy ">=net-misc/curl-7.21.5[ssl]" has unmet requirements.
- net-misc/curl-8.1.2::gentoo USE="adns ftp gnutls http2 imap pop3 progress-meter smtp ssl tftp -alt-svc -brotli -gopher -hsts -idn -kerberos -ldap -mbedtls (-nghttp3) -nss -openssl -rtmp (-rustls) -samba -ssh (-sslv3) -static-libs -telnet
-test -verify-sig -websockets -zstd" ABI_X86="(64) -32 (-x32)" CURL_SSL="openssl -gnutls -mbedtls -nss (-rustls)"
The following REQUIRED_USE flag constraints are unsatisfied:
curl_ssl_openssl? ( openssl )
The above constraints are a subset of the following complete expression:
ssl? ( exactly-one-of ( curl_ssl_gnutls curl_ssl_mbedtls curl_ssl_nss curl_ssl_openssl curl_ssl_rustls ) ) curl_ssl_gnutls? ( gnutls ) curl_ssl_mbedtls? ( mbedtls ) curl_ssl_nss? ( nss ) curl_ssl_openssl? ( openssl ) curl_ssl_rustls? (
rustls )
#########################################################################
.. I don't understand what is meant by "curl_ssl_openssl? ( openssl )" in
the above message. I assume it's talking about some USE flag, but which?
openssl? curl_ssl_openssl? As a matter of interest, I have
=dev-libs/openssl-3.0.9-r2 installed.
Please help me understand what's happening.
Thanks for the help!

I think it wants you to enable openssl or one of the other USE flag
options. Since I seem to recall having openssl installed already, I
just picked it. I'd try enabling that and see if the error goes away.
Hope that helps.

That was the problem. Although I had openssl installed, I hadn't set the
USE flag openssl for curl. When I did that, the problem went away. :-)

A REQUIRED_USE of 'X? ( Y Z )' means that if X is set, Y and Z must be
set. In boolean algebra, it can be expressed as a X => ( Y AND Z ).
See https://wiki.gentoo.org/wiki/Required_USE_flags
Hope that helps, have a lovely day.

To add to this, essentially what it's saying is either to change the USE flags of curl to include openssl or to change the CURL_SSL flag to "-openssl gnutls" (by adding "-curl_ssl_openssl curl_ssl_gnutls" to curl's USE flags) so that it aligns with your current curl USE flags.

OK, thanks! I tried to look up curl_ssl_openssl in use.desc and
use.local.desc, but couldn't find it there. I think openssl was missing,
too. So it didn't occur to me that they were themselves USE flags.

OK.

It does, thanks. I set the USE flag openssl for curl, and it all built
OK.

The description for CURL_SSL USE_EXPAND flags appears to be in
/usr/portage/profiles/desc/curl_ssl.desc
Just in case this wasn't mentioned yet in the thread, and to make sure
it's mentioned explicitly: CURL_SSL=openssl is expanded to
curl_ssl_openssl as a USE flag.
So my understanding is that the openssl flag controls building the curl
part that can use openssl, and curl_ssl_openssl selects that part to be
used for SSL.
From a quick (hopefully not *too* quick) glance at the ebuild, I think
this is because curl can be built with more than one SSL backend (the
USE flags that appear in USE=...), and the CURL_SSL=... USE_EXPAND flags
control which one gets to be the default.
(But someone more knowledgeable please correct me if this is wrong or
incomplete.)

In the USE flsgs you have: gnutls -openssl
In the CURL_SSL flags you have: openssl -gnutls
These 2 are contradicting each other. One says use gnutls instead of openssl,
the other says no, use openssl instead of gnutls.
Pick which option you want to use, and adjust the flags to agree on that
option.

Thanks, that's what I did. I set openssl for curl (in
/etc/portage/package.use), and the problem resolved itself.
