https://svn.boost.org/trac10/ticket/10910 <p> I want to build boost for arm64 instruction set. But getting error: </p> <blockquote> <p> error: "arm64" is not a known value of feature &lt;instruction-set&gt; </p> </blockquote> <p> This error occurs because builtin.jam file contains just following <strong>valid</strong> values for instruction-set feature: </p> <blockquote> <p> armv2 armv2a armv3 armv3m armv4 armv4t armv5 armv5t armv5te armv6 armv6j armv6j iwmmxt ep9312 armv7 armv7s </p> </blockquote> <p> I also checked several versions of boost - all of them don't contain arm64 value at builtin.jam file. Meanwhile arm64 is a valid argument to <strong>-arch</strong> option for compiler (e.g. clang) </p> <p> So my question is: why don't add there "arm64" value to the list of valid values for instruction-set feature? </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10910 Trac 1.4.3
