Makefile for programming guide tests is broken

[Scott Baden]

Fails in the link step

[Dan Bonachea]

This issue report lacks sufficient information to reproduce the problem.

Please attach a log of running the current UPCXX install command, so that we can see all the platform, compiler and version information it outputs.

[Dan Bonachea]

Here is a log of me installing and building the PG examples in the current develop head (3f95d6f) using the default /usr/bin/g++ compiler on the Sierra OS X 10.12.6 system in our machine room, which is running Xcode 8.3.3

You need to set CXX='c++ -std=c++11' when running the make command for the prog-guide, at least until we teach upcxx-meta to provide $CXX (which we really should).

As a side note, the /usr/local/bin/g++ you are using is rather old (5.2.0) and has some known bugs on Darwin (all the __textcoal_nt crap). It's also a different compiler family from your MPI in /usr/local/Cellar/open-mpi/2.1.1/bin/mpicc, which is clang-based (this can cause subtle interop-problems, and definitely affects relative optimization performance).

It looks like you have clang 8.1.0 installed (probably in /usr/bin/ from Xcode 8.3). I'd recommend setting your $PATH or $CC/$CXX to use that compiler instead.

[Scott Baden]

That broke my current Makefile I comment out the line that set CXX The error is above as Log2.txt

[Scott Baden]

The build for the programming examples fails as well Attached Log3.txt

[Dan Bonachea]

You need to use the same C/C++ compiler for both installing UPCXX and building applications. I believe you are mixing them, which will very likely break.

Please start over from scratch with CXX=/usr/bin/g++ CC=/usr/bin/gcc (which is actually clang).

[Scott Baden]

Will this work if I am using the C-shell and I specify the environment variables using the C-shell syntax?

[Dan Bonachea]

Yes, the equivalent setenv commands will also work.

You can confirm it's working by looking at the build lines to see that everything is invoking the correct compiler.

[Scott Baden]

OK, I have no build problems now that the compiler business has been cleared up.

[Scott Baden]

It has failed again. I wiped my local repo clean, and rebuilt. I've set the compiler variables to use Clang.
