Description Rex Dieter 2009-08-31 17:54:49 UTC

kdelibs fails to build on recent rawhide (works on F-11), seems to have to do with not detecting isinf/isnan properly.

From build.log:
...
-- Looking for isnan
-- Looking for isnan - not found.
-- Looking for isinf
-- Looking for isinf - not found.
...
/builddir/build/BUILD/kdelibs-4.3.1/kjs/operations.cpp: In function 'bool KJS::isNaN(double)':
/builddir/build/BUILD/kdelibs-4.3.1/kjs/operations.cpp:55: error: '_isnan' was not declared in this scope
make[2]: *** [kjs/CMakeFiles/kjs.dir/operations.o] Error 1
...

Doesn't seem to be related to non-use of _GNU_SOURCE (and friends), cmake seems to define these already (but I'm not 100% sure).

Someone on rawhide will probably have to take a closer look, see if this is kde or glibc (or other) at fault here.

Seems like it's our bug - it does not find isnan with %{cmake_kde4} macro but it does with just "cmake .." command in SPEC file.

Fixed, building now.  woo.  glibc to the rescue.
