https://svn.boost.org/trac10/ticket/10275 <p> On MacOS 10.9 / XCode 5.1, the SDKs are installed to a new location instead of "/Developer/": </p> <p> <a class="missing wiki">/Applications/Xcode</a>.app/Contents/Developer/Platforms/MacOSX.platform/Developer/ </p> <p> as a result the boost's darwin.jam fails to locate the available SDKs. The following command line will output errors: </p> <p> ./b2 macosx-version-min=10.7 </p> <p> errors: </p> <p> tools/build/src/build/feature.jam:493: in validate-value-string from module feature error: "10.7" is not a known value of feature &lt;macosx-version-min&gt; error: legal values: ... The workaround is create a soft link to new SDK location and everything works fine: </p> <p> cd / sudo ln -s <a class="missing wiki">/Applications/Xcode</a>.app/Contents/Developer/Platforms/MacOSX.platform/Developer/ Developer </p> <p> FYI: The XCode5 installs iOS sdks under: </p> <p> <a class="missing wiki">/Applications/Xcode</a>.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/ </p> <p> so darwin.jam should search both /Developer/ and these new SDK locations for installed SDKs. </p> <p> </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10275 Trac 1.4.3 stefano.bider@… Mon, 23 May 2016 14:23:22 GMT
