macvim +huge fails to build under Xcode 10

[MaurizioLoreti]

After upgrading to Mojave, I deleted all installed ports, reinstalled macports from source and typed sudo port install macvim +huge. The command failed; the log is in attachment. TIA for any help!

same problem here. macvim failes to build on macOS Mojave with both of the following commands:

port install macvim +huge
port install macvim +big

I have not yet upgraded to Mojave, so I cannot test this right now. Sorry.

It is very likely caused by changes in Xcode 10. Looks like Apple developers did not know how to properly look up the home directory of a user and hardcoded the /Users path? I have no idea why else it would want to store things at /Users/macports/....

This worked:

# Old pre-compiled headers could influence build, #26723
build.args          XCODEFLAGS="CACHE_ROOT=${workpath}/caches"

+ # this port does not build with the new xcode build system at present
+ if {[vercmp ${xcodeversion} 10.0] >= 0} {
+ build.args    XCODEFLAGS="CACHE_ROOT=${workpath}/caches -UseNewBuildSystem=NO"
+ }

$ port -v installed macvim
The following ports are currently installed:
  MacVim @8.1.snapshot151_0+huge (active) platform='darwin 18' archs='x86_64' date='2018-09-30T17:12:41-0700'

However, it doesn't work right on my system. The macvim window wildly refreshes black and white with any mouse movement in the window. Possibly other errors to be discovered.

Builds -- but is unusable.

In the meanwhile, I downloaded the .dmg file from ​https://github.com/macvim-dev/macvim/releases and installed MacVim from there. I will wait for a fix coming...

[kencu (Ken)]

So there are two different issues with MacVim. The build failure is fixed by the small Portfile bit above, which we might as well commit.

+ # this port does not build with the new xcode build system at present
+ if {[vercmp ${xcodeversion} 10.0] >= 0} {
+ build.args    XCODEFLAGS="CACHE_ROOT=${workpath}/caches -UseNewBuildSystem=NO"
+ }

MacVim is unusable after that build however. There are build issues against the 10.14 SDK being tracked here <​https://github.com/macvim-dev/macvim/issues/751> and for which there are temporary workarounds while a fix is being finalized.
