[gentoo-user] Build error in threads.c, maybe related to nptlonly use flag.

[Bob Young]

Hi all,

In advance please pardon the long post.

I'm trying to do a  stage 1/3 install as described here:
http://forums.gentoo.org/viewtopic-t-345229.html

I've successfully rebuilt the tool chain and am at the stage of rebuilding
the system with the new toolchain. Unfortunately I've encountered a build
error with krb5-1.4.3 that I don't know how to solve. The following is what
I believe to be the relevent output from #emerge -e system

***********************************

I think the "nptl nptlonly " use flags are relevant to this, but am not
sure. I know the "kerberos" flag is related, but since the box will be
interacting with an Active Directory domain controler kerberos seems
appropiate to have.

I'd prefer not to give up nptlonly flag to solve this, but if that's the
only way to avoid this error, I guess I'll have no choice, but most of all I
would like to understand exactly what and where the problem is. If it's
something moderately simple, like threads.c not "paying attention to a
define" or something similar, I might try and fix it, but either way I'd
like to understand it more than I currently do.

Output that seems particularly interesting:

Output: "threads.c:145: error: `pthread_mutexattr_setrobust_np' undeclared
(first use in this function)"

Comment: Okay that's the error pthread_mutexattr_setrobust_np is undeclared.

Output "checking for pthread_mutexattr_setrobust_np... no"     (<- From
configure)

Comment: Hmmm....Configure knows it's not available in the "normal" way.

Output: "-DHAVE_PTHREAD_MUTEXATTR_SETROBUST_NP_IN_THREAD_LIB=1"   (<- From
gcc )

Comment: What is this supposed to signify?

Output: checking for pthread_mutexattr_setrobust_np in -lc... yes   (<- From
configure)

Comment: Okay...It's available in "-lc" what does that mean? and if it's
available why is it causing a build error?
Comment: What does "-lc" mean? Would declaring
pthread_mutexattr_setrobust_np as "external" on the condition of some define
solve the problem?

Again sorry for the long post, TIA to anyone who can share some insight.

Bob Young
