Besides giving Linus the possibility to change the headers +more freely it has another reason: user level programs now do not +always use the same types like the kernel does. + +I.e., the libc abstracts the use of types. E.g., the sigset_t type is +in the kernel 32 or 64 bits wide. In glibc it is 1024 bits wide, in +preparation for future development. The reasons are obvious: we don't +want to have a new major release when the Linux kernel gets these +functionality. Consult the headers for more information about the changes. + +Therefore you shouldn't include Linux kernel header files directly if +glibc has defined a replacement. Otherwise you might get undefined +results because of type conflicts. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ diff --git a/Makeconfig b/Makeconfig index dd6d6297b2..8b82a31124 100644 --- a/Makeconfig +++ b/Makeconfig @@ -91,7 +91,8 @@ export full-config-sysdirs := $(full-config-sysdirs) # changes and so config.status would be run every time; the dependence of # config.make should suffice to force regeneration and re-exec, and the new # image will notice if config.h changed. -$(common-objpfx)config.make: $(common-objpfx)config.status $(..)config.h.in +$(common-objpfx)config.make: $(common-objpfx)config.status \ + $(..)config.make.in $(..)config.h.in cd $(<D); $(SHELL) $(<F) # Find all the sysdeps configure fragments, to make sure we re-run @@ -94,7 +94,7 @@ install-others = $(inst_includedir)/gnu/stubs.h install-bin = glibcbug ifeq (yes,$(build-shared)) -before-compile += $(objpfx)lib-names.h +before-compile += $(objpfx)gnu/lib-names.h install_others += $(inst_includedir)/gnu/lib-names.h endif @@ -196,12 +196,13 @@ ifeq (yes,$(build-shared)) # Like gnu/stubs.h the gnu/lib-names.h header is not used while building the # libc itself.
