The build machine architecture is aarch64 right? Not x86_64. > and got the same results in the config.log. This is expected, because you specified the same triplet for both --build and --host. > Apparently, specifying —build is not sufficient to enter cross > compiling mode, as configure still runs the test program which does > not fail and as a result it incorrectly deduces that cross compilation > is not being used. Cross compiliation mode is entered if the build triplet (which designates the machine you are using to build the program) is different from the host triple (which designates the machine the program will ultimately run on). You have specified both as x86_64-apple-macos10.10, so configure will treat this as a native compilation as you have told it you are building and running on the same system. Cheers, Nick
