[LLVMdev] use of undeclared identifier '__NR_*' error while building clang
Hi guys,
I am following this[1] tutorial to install clang. However, I have made a
small change in the configure command, and I am running it with
'--enable-optimized' option to avoid the debug build.
I am getting the errors (given at the end) related to *undeclared
identifiers '__NR_*'*. Can someone please provide some input about how
to
tackle this issue?
On my other machine, I followed the same guide[1] (without the
--enable-optimized option), and everything built successfully.

-cfe-dev Based on your question on IRC, it sounds like there's something wrong with your Linux headers. Make sure you have something that provides the syscall numbers in /usr/include.

[LLVMdev] [cfe-dev] use of undeclared identifier '__NR_*' error while building clang
Hi, Can you provide details about your system (uname -a)? It is weird that you don't have __NR_open defined in your system headers. As a workaround, you may drop compiler-rt repository from your checkout, it's possible to build Clang without it.

[LLVMdev] [cfe-dev] use of undeclared identifier '__NR_*' error while building clang
Hi Reid, Thanks for the reply ! Earlier the build was complaining about not having /asm in /usr/include so I created a symbolic link to it with asm-generic, after that I am encountering this issue. I just grep'ed for '__NR_fork', and I can see these numbers in the header files. sandeep at ubuntu:/usr/include$ grep -rni __NR_fork . ./asm-generic/unistd.h:850:#define __NR_fork 1079 ./asm-generic/unistd.h:852:__SYSCALL(__NR_fork, sys_fork) ./asm-generic/unistd.h:854:__SYSCALL(__NR_fork, sys_ni_syscall) ./asm-generic/unistd.h:858:#define __NR_syscalls (__NR_fork+1) ./x86_64-linux-gnu/asm/unistd_x32.h:51:#define __NR_fork (__X32_SYSCALL_BIT + 57) ./x86_64-linux-gnu/asm/unistd_64.h:61:#define __NR_fork 57 ./x86_64-linux-gnu/asm/unistd_32.h:6:#define __NR_fork 2 ./x86_64-linux-gnu/bits/syscall.h:70:#define SYS_fork __NR_fork ./x86_64-linux-gnu/bits/syscall.h:418:#define SYS_fork __NR_fork ./x86_64-linux-gnu/bits/syscall.h:730:#define SYS_fork __NR_fork So these numbers are available in /usr/include. Are these not sufficient? Thanks, Sandeep.

[LLVMdev] [cfe-dev] use of undeclared identifier '__NR_*' error while building clang
Hi Alexey ! Thanks for the reply ! Below is the output of 'uname -a' sandeep at ubuntu:/usr/include$ uname -a Linux ubuntu 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux I recently upgraded my Linux version (to Ubuntu 14.04). Could the issue be because of that? So to drop compiler-rt, I can just delete the whole directory and do an incremental build? The reason I'm asking this is - it takes more than a couple of hours for the build on my system. It would be great if I can avoid it. Please let me know. Thanks and regards, Sandeep.
