erg (JIRA User), @shahmishal, did anything change in preview 3?

Comment by Doug Coleman (JIRA)

Preview 3 has the flag. It got removed in master by 14b2dd5.

Can you please provide the swift sha you are building from?

Thanks,
Mishal Shah

  Available settings. Each setting corresponds to a variable,
  obtained by upcasing its name, in this script. A variable
  with no default listed here will be unset in the script if
  not explicitly specified. A setting passed in the 3rd form
  will set its corresponding variable to "1".

Still can not build with 3.0.1 GM

I am working on Ubuntu 16.10 x64

Hi Zhifeng,

I would recommend building from github rather than from the .zip, but I just tried it and I'm not getting your error at all.

Here's what worked for me:

bash```
wget https://github.com/apple/swift/archive/swift-3.0.1-PREVIEW-3.zip
unzip swift-3.0.1-PREVIEW-3.zip
mv swift-swift-3.0.1-PREVIEW-3 swift
cd swift
./utils/update-checkout --clone-with-ssh --skip-repository swift
./utils/build-script -r -t
```

To build from github:

bash```
git clone git@github.com:apple/swift.git
cd swift
./utils/update-checkout --clone-with-ssh
./utils/build-script -r -t
```

If you grep for ``llvm-enable-assertions`` you will see that it exists:

```
erg@rad:~/swift$ grep -r llvm-enable-assertions
utils/build-script: "--llvm-enable-assertions", str(args.llvm_assertions).lower(),
utils/build-script-impl: llvm-enable-assertions "1" "enable assertions in LLVM and Clang"
```

If your ``grep`` does not find that output, something is wrong. Are you sure that there are no other Swift directories that it's trying to build instead of the downloaded version?
