Bug 555708 – net-misc/openssh-6.9_p1-r2[ldns,-ssl] fails to build: error: conflicting types for SHA512_Transform

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Nicholas Fish 2015-07-23 16:56:25 UTC]

Attempting to compile the latest version of openssh with the ldns USE flag enabled results in type definition conflicts between the openssl and openssh include files.

Reproducible: Always

Steps to Reproduce:
USE="ldns" emerge openssh
Actual Results:

Can you please also attach emerge --info ?

Thanks

pretty sure it's because you've disabled USE=ssl and ldns requires openssl.
if you re-add USE=ssl, does it build ?

Yes, re-enabling the 'ssl' USE flag (it was toggled off by package.use) results in a successful emerge of openssh.

Thanks

should be all set now in the tree; thanks for the report!

Commit message: List USE=ssl as a requirement for USE=ldns and clean up the ldns deps a bit
