Red Hat Bugzilla – Bug 575157
cman cannot be rebuilt with latest nss libraries
Last modified: 2016-04-26 11:00:49 EDT
Description of problem:
cman srpm rebuild fails with:
/usr/include/nspr4/prlink.h:52: warning: function declaration isn't a prototype /usr/include/nspr4/prlink.h:211: warning: function declaration isn't a prototype
Version-Release number of selected component (if applicable):
# rpm -q nss nspr cman
Steps to Reproduce:
1. rpmbuild -ba cman.spec
I don't get the warm and fuzzies from the fact that use of nss makes me DISABLE compiler warnings.
It stems from a bad function prototype in prlink.h:
For fence_xvm, the best option is to use:
#pragma GCC diagnostic ignored "-Wstrict-prototypes"
... at the beginning of the file(s) where nss or nspr includes are used. This prevents the need to ignore strict-prototypes elsewhere in the code base during compilation.
Unfortunately this trick doesn't work with gcc version included in rhel5.
You need to use -Wno-strict-prototypes.

Patch fixing compile against nspr-4.8.2+
should be clone for RHEL4 too
cman-kernel-2.6.9-56.7.el4_8.12.can be built with nss-220.127.116.11.3-1.el4_8.2 but fails to build if 3.12.6-1.el4_8 is installed
cman-kernel does not use nss; I do not understand how building it could fail due to nss or nspr updates.
Furthermore, if there is an identifiable point at which an update of a library broke compilation of applications, it is a regression in the library.
This isn´t a new bug. nss maintainers have been aware of this issue for sometime (reported several months ago against Fedora).
And for sure not a cman issue.
Time nss people fix their stuff.
I do not see value in sweeping the error under the rug by not compiling with -Wstrict-prototypes. Consequently, I have removed -Werror.
A change to nss caused this (not nspr or gcc, as previously suspected)
Patch in https://bugzilla.redhat.com/attachment.cgi?id=409353
that patch should work for this bug as well.
