<p class="MsoNormal">Thanks for the hints. I did the suggested method of forcing the Command-Line Tools installation by Software Update and it told me that it was going to install the Xcode 10.3 CLT. It seems that Xcode 11 now has the CLT included inside Xcode,
so that version is not installed by Software Update.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">work. I deleted my whole Xcode.app directory and reinstalled Xcode 11.2. Now that I have a clean Xcode 11.2, it does not have the MacOSX10.14.sdk installed and the gcc7 and gcc9 installations from MacPorts are still
depending on that. I tried reinstalling the command-line tools, as someone suggested yesterday, but it tells me that they are already installed.<span style="font-size:12.0pt"><o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in">I uninstalled my gcc7 port and reinstalled it to see if it would update the libraries. The port install command installed the precompiled binaries that are linked to the MacOSX10.14.sdk, so it won’t run correctly.
Can I force MacPorts to recompile gcc7 instead of using the precompiled binaries?<span style="font-size:12.0pt"><o:p></o:p></span></p>

<p class="MsoNormal">I ran the full build from source of gcc7. Good thing I had my MacBook battery replaced as it was down below 20% by the time the compilation finished. Now when I can see that the gcc7 is linked to the Command-Line Tools version of the MacOSX10.14.sdk,
which works well. Maybe MacPorts will need to use this path for people on Mojave 10.14.6 that have Xcode 11.x<o:p></o:p></p>
