Compiling issue on Centos7

[harry9679]

I encountered an error when I tried to build and install the newest version of toolbox (18.5.1) on Centos 7.3.

As explained in the documentation, I first installed the latest swift distribution, which is swift-5.6.3-RELEASE. Then I follow the steps in the documentation:

git clone https://github.com/vapor/toolbox.git
cd toolbox
git checkout <desired version>
make install

I got the same issue mentioned in #355. And I upgraded git to 2.36.1 to solve the issue.

After I solved the issue, I got another one, the outputs are:

swiftc ./scripts/build.swift
./build
$ swift build --disable-sandbox --configuration release -Xswiftc -cross-module-optimization

I'm not sure how to fix this. Has anyone else met the same problem?

Hmm this looks like a missing dependency I think? Can you build a simple Swift package or just SwiftNIO?

[harry9679]

I tried another SwiftNIO example and got the same error. I found another thread on https://forums.swift.org/t/vapor-build-crash-swift-5-6-2-centos7/58302/4 . I'll try in other environments. Thank you!

@harry9679 ok cool, best thing would be the create an issue on NIO and see what they say

Going to close this as things should be working with the latest main and Swift release. Feel free to reopen if not!
