[Please confine your replies to toolch...@freebsd.org to keep the thread on the most relevant list.]For the past several years we've been working towards migrating from GCC to Clang/LLVM as our default compiler. We intend to ship FreeBSD 10.0 with Clang as the default compiler on i386 and amd64 platforms. To this end, we will make WITH_CLANG_IS_CC the default on i386 and amd64 platforms on November 4th. What does the mean to you? * When you build world after the default is changed /usr/bin/cc, cpp, and c++ will be links to clang. * This means the initial phase of buildworld and "old style" kernel compilation will use clang instead of gcc. This is known to work. * It also means that ports will build with clang by default. A major of ports work, but a significant number are broken or blocked by broken ports. For more information see: http://wiki.freebsd.org/PortsAndClang What issues remain? * The gcc->clang transition currently requires setting CC, CXX, and CPP in addition to WITH_CLANG_IS_CC. I will post a patch to toolchain@ to address this shortly.
I assume this will be done, tested and committed before 2012-11-04 (or whenever the switchover date is).
* Ports compiler selection infrastructure is still under development.
This should be a prerequisite before making the switch, given that ports will be broken without a work-around for building them with gcc. -- DE _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
