Bug 146654 – net-misc/openssh-4.3_p2-r2 fails with USE=static due to not linking -ldl

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexander Skwar 2006-09-07 01:25:47 UTC]

I tried to compile openssh with the following flags:

[ebuild   R   ] net-misc/openssh-4.3_p2-r2  USE="-X* -X509 -chroot hpn -ipv6 -kerberos -ldap -libedit pam (-selinux) -sftplogging -skey -smartcard static tcpd" 0 kB

This failed:

I tried re-compiling glibc and upgraded to dev-libs/openssl-0.9.8b. After the upgrade to openssl-0.9.8b, I ran

# revdep-rebuild --library libssl.so.0.9.7
# revdep-rebuild --library libcrypto.so.0.9.7

I still get this error.

[Comment 1 Alexander Skwar 2006-09-07 01:43:53 UTC]

I upgraded to openssl-0.9.8c - no change, still the same error.

[Comment 2 Alexander Skwar 2006-09-07 02:07:58 UTC]

With USE=-static, I could compile openssh.

[Comment 3 SpanKY 2006-09-07 21:36:45 UTC]

fixed in cvs

[Comment 4 Joel Martin (RETIRED) 2006-09-14 09:59:37 UTC]

I don't think using pkg-config to figure out paths and libs is really the right approach for this situation. Consider when ROOT is something other than "/". In that case the linking will either fail, or happen with the wrong libraries.

Not sure what the right approach is. ${ROOT}/usr/bin/pkg-config would be nice but that assumes that pkg-config understand non-default ROOT=/somethingelse builds.

Perhaps we should test if ROOT="/" and if so use pkg-config, otherwise go with sane defaults (such as linking with -ldl if use static).

[Comment 5 SpanKY 2006-09-14 13:54:15 UTC]

you've got a choice ... pkg-config or libtool or nothing

pkg-config/libtool not working with ROOT/cross-compiling is a larger issue and not openssh specific in any way
