[swift-dev] Glibc.swift: error: no such module 'SwiftGlibc'

[Eric Wing]

I am trying to build Swift for Android and I'm getting the error:
Glibc.swift:13:19: error: no such module 'SwiftGlibc'


I found several other posts asking about this problem for Linux, but
no solid resolution.

https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20160418/001741.html
https://www.mail-archive.com/swift-users@swift.org/msg02098.html
https://aur.archlinux.org/packages/swift-language-git/?comments=all


My problem is a little different. Besides the Android part, I should
mention a few other things:

- I am building Swift as ReleaseAssert under Steam-Runtime (which uses
clang 3.6.0), where I get the error.

- If I build as DebugAssert (Steam-Runtime), I do not see this problem
(and the build finished). I'm a little surprised debug worked but not
release.

- If I build under Ubuntu 16.10, I do not hit this problem (both debug
and release)

- I do not see any other error messages as stated in the other thread
like (ioctl.h not found). My error message is pretty unhelpful about
why it failed. (Pasted below)

- I looked for a glibc.modulemap for my broken build. I do not see any
in the build directory, nor does it exist on my system. (I do see it
created in the successful build.)


Anyway, I really could use some guidance on how to get around/fix this
problem. I want to use Steam-Runtime because I can build a Swift/Linux
compiler binary that I can run on most Linux distros, not just Ubuntu
16.10.

I appreciate any help.
Thanks,
Eric
