Title: The header files fcntl.h and linux/fcntl.h are incompatible Status in glibc package in Ubuntu: New Status in linux package in Ubuntu: New Bug description: The program try.c, below, does not compile. Though with HAVE_ARCH_STRUCT_FLOCK and HAVE_ARCH_STRUCT_FLOCK64 defined, it compiles. But then fails again to compile, when _GNU_SOURCE is also defined. I expect this to compile in all three cases. $ cat try.c //#define _GNU_SOURCE //#define HAVE_ARCH_STRUCT_FLOCK //#define HAVE_ARCH_STRUCT_FLOCK64 #include <fcntl.h> #include <linux/fcntl.h> int main(int argc, char *argv[]){} $ gcc try.c In file included from /usr/include/x86_64-linux-gnu/asm/fcntl.h:1:0, from /usr/include/linux/fcntl.h:4, from try.c:5: /usr/include/asm-generic/fcntl.h:195:8: error: redefinition of ‘struct flock’ struct flock { ^~~~~ In file included from /usr/include/fcntl.h:35:0, from try.c:4: /usr/include/x86_64-linux-gnu/bits/fcntl.h:35:8: note: originally defined here struct flock ^~~~~ $ gcc -DHAVE_ARCH_STRUCT_FLOCK -DHAVE_ARCH_STRUCT_FLOCK64 try.c ## this is ok $ gcc -D_GNU_SOURCE -DHAVE_ARCH_STRUCT_FLOCK -DHAVE_ARCH_STRUCT_FLOCK64 try.c In file included from /usr/include/x86_64-linux-gnu/asm/fcntl.h:1:0, from /usr/include/linux/fcntl.h:4, from try.c:5: /usr/include/asm-generic/fcntl.h:155:8: error: redefinition of ‘struct f_owner_ex’ struct f_owner_ex { ^~~~~~~~~~ In file included from /usr/include/x86_64-linux-gnu/bits/fcntl.h:61:0, from /usr/include/fcntl.h:35, from try.c:4: /usr/include/x86_64-linux-gnu/bits/fcntl-linux.h:267:8: note: originally defined here struct f_owner_ex ^~~~~~~~~~ $ gcc --version | head -1 gcc (Ubuntu 7.2.0-8ubuntu3) 7.2.0 $ lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 $ dpkg -S /usr/include/x86_64-linux-gnu/bits/fcntl.h libc6-dev:amd64: /usr/include/x86_64-linux-gnu/bits/fcntl.h # Package: libc6-dev # Version: 2.26-0ubuntu2 $ dpkg -S /usr/include/x86_64-linux-gnu/asm/fcntl.h linux-libc-dev:amd64: /usr/include/x86_64-linux-gnu/asm/fcntl.h # Package: linux-libc-dev # Version: 4.13.0-19.22 Regards, Mike To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1739300/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
