Couldn't create build system & environment

Nonepse opened this issue · comments

Running on macOS 10.13.4 with Xcode 9.4 installed, I get the following errors when trying to build my project:

$ ./xcbuild -workspace MyProject.xcworkspace
error: couldn't create build system
error: couldn't create build environment

Am I missing something?

commented

I don't think you're missing anything; the build system and the build environment are defined by xcspec files, I believe, which should be hosted in your developer root (and therefore discoverable).

  1. When was the last time you could build your project with xcbuild? When did you last build xcbuild? What version of Xcode did you have then?
  2. Is MyProject.xcworkspace doing anything interesting? How'd you create it? If you create a vanilla (I assume iOS) workspace and try to build it, do you get the same errors?

Thanks for the reply @Ktwu. But mine won't be very helpful :(

  1. First time ever on this machine
  2. I first tried with a rather large project. Thinking it could be the issue, I tried with a vanilla one: same results

i have the same problem and i /think/ i know what it is but not quite sute how to solve if.

using the xcode-select from the project prints out the following path

'private/var/db/xcode_select_link'

without the leading slash, and without that, its not a valid path. i just built and installed xcbuild for the first time today and haven ever successfully built anything with it because i get an identical error.

follow up on this- the incorrect path was most certainly the problem for me. and was "solved" by doing

"ln -s /private private"

from my pwd in the command line. not sure how to properly fix it, but once i did this i could actually use xcbuild succesfully. bad path logic somewhere. not sure where.

you should "export DEVELOPER_DIR=/Applications/Xcode.app" first
