/usr/include is present but there is no c++ file in it. Is it the source of problem?
Any help would be greatly appreciated

What's clang-1000? Anyway I guess you need to upgrade clang to get c++11 support.

What's weird here is that setup.py just says to run make, but the makefile doesn't run that commandline.

So the basic problem here is that pip install jsonnet is building Jsonnet from C++ source. For lots of people that's not a big deal, as it's not much code and it doesn't have crazy dependencies. However for other people whose machines are not set up for building, particularly Mac and Windows machines, this is too much of a burden. When we switch to Go, it's going to get worse because even fewer end user machines will be set up to build Go, especially when we expect a newer version of Go.

The solution is to put prebuilt binaries for a range of platforms in the pypi repository, so that pip install only has to download from the web, not build anything.

Hi, had this issue myself, and fixed it by editing the CXXFLAGS in your environment.
My ENV file had CXXFLAGS= -I/usr/local/opt/libomp/include
I changed it to CXXFLAGS= -std=c++11 -stdlib=libc++
which worked.

[sbarzowski]

Probably it's -stdlib=libc++ that made the difference. We already have -std=c++11 in our build files. And the -I stuff seems completely irrelevant and shouldn't change anything.
