Hey gargoyle (JIRA User),

I just tried to reproduce this error, but was unable to. I tried it with the nightly docker image and also downloading the toolchain from swift.org into a plain CentOS 7 docker. Did you install all necessary dependencies listed under https://swift.org/download/#linux ?

I don't have root on this system, unfortunately. I downloaded the tarball, and then did this:

yumdownloader --destdir ~/rpm --resolve binutils gcc git glibc-static libbsd-devel libedit libedit-devel libicu-devel libstdc++-static pkg-config python2 sqlite

For each rpm it downloaded, I did an "rpm2cpio x.rpm | cpio -id" in a ~/centos directory.

Then I added "~/centos/usr/sbin ~/centos/usr/bin ~/centos/bin" to my path, and set LD_LIBRARY_PATH to

/lib:/lib64:/usr/lib:/usr/lib64:/home/scott/centos/usr/lib:/home/scott/centos/usr/lib64

Running the build command still gets the same error.

The vendor just installed the other missing packages, but they're not going to change the system header file. Even with them doing that, I'm still getting the same error.

Can you run a CentOS 7 docker container or VM and check if it reproduces there for you as well? Also, could you try running the command in a debugger to get more information on the crash?

OK, figured it out. Swift build is trying to execute things from /tmp, and the vendor mounted /tmp with the no-exec option because of all the WordPress exploits that try to use /tmp. I manually set TMPDIR environment to somewhere in my home directory and it will now build

Nice! Glad you could resolve the problem.
