1.3 wiz 1: This page explains how to use clang with the NetBSD base system.
1.2 gdt 2: See also [how to use clang to build packages](../pkgsrc/clang/).
1.1 gdt 3:
4: \todo: review this entire page.
6: Since NetBSD 6, the base system has included clang, but it is not
7: built or used by default.
9: \todo Explain if there are or aren't plans to enable it by default, or
10: to switch, keeping in mind that compiler support varies by architecture.
12: There are three steps that can be taken with clang; each depends on the previous.
14: # Building clang
16: To build clang as part of the build, set
20: in mk.conf before running "build.sh release".
22: This will build clang, which will appear in /usr/bin/clang and also
23: build libraries that clang needs. NetBSD itself will not be built
24: with clang, but you will be able to use clang to build programs.
26: # Using clang to build the NetBSD base system
28: In addition, set
32: to cause clang to be used instead of gcc.
34: # Not building gcc
36: On a system that builds clang and uses it to build the base system,
37: you can refrain from building gcc, by additionally adding:
1.4 ! gdt 40:
! 41: # status
! 43: On NetBSD-current, clang builds successfully on several architectures.
! 44: These builds are with all three of the above flags enabled.
