I already made links, as suggested in related tickets, like

$ cd /Applications/Xcode.app/Contents/Developer/Toolchains/
$ sudo ln -s XcodeDefault.xctoolchain OSX10.{13,15}.xctoolchain

But this did not help!

Thanks a lot for any help - JFB

The error in the log is:

Assertion 'common_variable_is_legal_name XCODE_SDK_10_15.4_XCODE' failed

Here is the corresponding upstream issue:

​https://github.com/osxfuse/osxfuse/issues/692

The upstream issue has been closed with this remark:

The FUSE source code, that is available in the repository, is version 3.8.3, which is not compatible with macOS 10.15 or Xcode 11. The source code for the latest version of FUSE, that is compatible with Catalina, is not publicly available.

Does this mean, the project is dead for macports?

This looks like a repeat of #59316

[dershow]

With this port unavailable on 10.15, I also can't install ports that depend on it: ntfs-3g, autopsy,sleuthkit,libewf,testdisk

[museum-future (Skynet)]

why not just install ​https://osxfuse.github.io/

then force ntfs-3g to recognize it?
