Flang Binary Release 2019-03-29

Flang is a Fortran compiler targeting LLVM.

The source is at http://github.com/flang-compiler/.
There are 4 repositories:

  • llvm: The version of LLVM that we use to build Flang.
  • flang-driver: A Clang fork used as the basis of the Flang driver.
  • openmp: The version of OpenMP we use to buidl flang.
  • flang: The Flang compiler itself.

This binary release was created from the flang_20190329 tag of Flang.
It contains the binaries and libraries suitable for running
Flang (LLVM 7.0) on x86_64 and OpenPOWER distributions.

Community Resources

We have mailing lists for announcements and developers.
Here's the link with the sign-up information:

http://lists.flang-compiler.org/mailman/listinfo

We have a flang-compiler channel on Slack. Slack is invitation
only but anyone can join. Here's the link:

Installing

To install the binary release, untar the .tgz file in
a location suitable for you. Add the bin directory to
your PATH and lib directory to your LD_LIBRARY_PATH,
after which you should be able to execute Flang.

Building Your First Program

To test your installation, create a simple "hello world" program, like the
following:

   program hello
     print *, 'hello world'
   end

Next, compile the program in the following manner. We will assume the
program is in a file called hello.f90

$ flang hello.f90

If the build succeeds, then you can execute the program:

$ ./a.out
