cctools build failure

[LXuipp]

I try to install gcc8 with latest MacPort on macOS Mojave (10.14.1) with Xcode (10.1), and I got the following ERRORs:

--->  Computing dependencies for cctools
--->  Building cctools
Error: Failed to build cctools: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_cctools/cctools/main.log for details.
Error: Unable to execute port: upgrade cctools failed

How to fix it ?

Please attach the main.log mentioned in the error message.

Where is your Xcode located?

xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist

See the new main.log file

The linker seems to be having trouble linking your objects.

Please show us what ld64 versions you have installed. The output of this command should do it:

port -v installed | grep ld64

also, don't forget good housekeeping. Always clean out a failed build directory before trying again, or you are starting from an uncertain state, and will likely have unpredictable results:

sudo port clean cctools
sudo port -v install cctools

ld64 @3_0 platform='darwin 17' archs='x86_64' date='2017-12-12T07:23:56+0800' ld64 @3_1+ld64_xcode (active) platform='darwin 18' archs='x86_64' date='2018-11-30T15:51:11+0800' ld64-latest @274.2_2+llvm39 (active) platform='darwin 17' archs='x86_64' date='2017-12-12T07:23:55+0800' ld64-xcode @2_1 (active) platform='darwin 18' archs='x86_64' date='2018-11-30T15:51:10+0800'

After

sudo port clean cctools sudo port -v install cctools

Install gcc8, done.

Thanks very much.
