Description Deji Akingunola 2009-08-28 22:38:53 UTC
Description of problem:
I got the error below trying to build tokyocabinet in koji (http://koji.fedoraproject.org/koji/taskinfo?taskID=1641937). The package builds fine in F-11 branch.

In file included from /usr/include/math.h:416,
                 from tcutil.h:35,
                 from tcutil.c:17:
/usr/include/bits/mathinline.h: In function '__signbitf':
/usr/include/bits/mathinline.h:39: error: expected ')' before ':' token
/usr/include/bits/mathinline.h: In function '__signbit':
/usr/include/bits/mathinline.h:46: error: expected ')' before ':' token

Version-Release number of selected component (if applicable): glibc-2.10.90-17

Comment 1 Owen Taylor 2009-08-28 23:40:45 UTC
This can be reproduced (tested on x86_64) with:

cat <<EOF > math-test.c
#define _XOPEN_SOURCE 600 /* C99 */
#include <features.h>
#include <math.h>

int main()
   return 0;
gcc -o math-test.o math-test.c -O2

and is probably going to keep a large fraction of packages from building.

Comment 3 Andreas Schwab 2009-08-31 09:42:48 UTC
The testcase in #c1 compiles without problem.  Only packages that use --std=c99 fail.

Comment 5 Owen Taylor 2009-08-31 16:42:03 UTC
Andreas - that testcase reproduced it for me (unless I typo'ed something putting it into the bug report.). Were you testing on x86_64? But yes, --std=c99 would also be a way of enabling the bad portions of mathinline.h.

Comment 6 Andreas Schwab 2009-09-01 12:02:00 UTC
Without --std=c99 the compiler will happily accept all extensions.

Comment 7 Andreas Schwab 2009-09-01 12:53:17 UTC
Fixed in 2.10.90-18.
