Description Daniel Drake 2011-10-09 12:23:48 EDT
Functions such as creall() and cimagl() are not available on ARM (reproduced with glibc-2.14-7), due to failing to meet these preprocessor conditions in complex.h:

#if (__STDC__ - 0 || __GNUC__ - 0) \
    && (!defined __NO_LONG_DOUBLE_MATH || defined __LDBL_COMPAT)

Packages which use these functions and use -Werror during build (such as libmpc) are failing to compile as a result.

The use of -Werror is indeed questionable, but this does seem to be a glibc bug. Probably this one: http://sourceware.org/bugzilla/show_bug.cgi?id=10103

I confirmed that Jakub's patch still hasn't been applied in glibc HEAD.

alternative fix

This alternative fix was submitted by a Fedora-ARM contributor. Not sure if it is better or worse than Jakub's patch from 2009.

Please let us know how we can help this issue get fixed.
Comment 2 Jakub Jelinek 2011-10-26 18:01:19 EDT
That is a bad idea, because then you penalize glibc quite a bit.
Comment 3 Daniel Drake 2011-10-26 18:06:30 EDT
OK, thanks for the quick response. Is your 2009 patch the right way to go then? Would it help you if we rediff/retest that patch against current glibc?

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 5 Jeff Law 2012-02-09 12:09:15 EST
Looks like this was fixed in the upstream sources on 11/4 and thus would be included in rawhide.

If this is still an issue, please reopen the report with further details as to why the upstream fix was insufficient.
