4.0.4-alt105 Some C compiler flags (CFLAGS) are desired for compilation, but not when running ./configure (or similar scripts). Now CFLAGS et al. environment variables are set and exported by %configure. Examples: 1. Optimization flags may be unwanted in ./configure because they slow down the tests. (Instead, something like -O0 may be wanted if this is not the default.) 2. -Werror (added to %optflags by %def_enable Werror or by other ways) make the tests in ./configure behave differently. A mechanism should be thought up to "filter" out the flags which are bad for ./configure before running ./configure, but to add them back when running make. Perhaps, exporting CFLAGS two times (with different values) would work for most packages, but I need a closer look at the packages to find this out. (A BRP check that would check that the resulting files have been compiles with flags which include all %optflags would help to see whether the new mechanism would work as expected en masse.)
Проверка актуальности: не реализовано. В rpm-build 4.0.4.214-alt1 макрос %configure по-прежнему экспортирует CFLAGS/CXXFLAGS с полным набором %optflags (включая -O2 и добавленный пакетом -Werror), механизма отбора флагов «для configure» и «для make» нет.
