Releases: flang-compiler/flang
March 2019 Binary Release
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.

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
