The PGI Community Edition compilers are a set of no-cost, non-open-source, high performance compilers for:
pgc++(C++17, Linux only)
If you have an older PGI compiler installed, uninstall that first to avoid license server issues–even when using the no-cost Community Edition.
Download and install PGI Community Edition:
- Linux: sudo not required, but must be on symbolic-link-aware drive (not ExFAT)
- Windows: Requires Visual Studio
- MacOS is no longer supported by PGI after version 19.10.
PGI compiler is over 2 GB download. CUDA install is optional.
We assume PGI was installed under “~/.local/pgi” – add to
Open a new terminal to use PGI
use PGI command prompt–you may need to do
set FC=pgfortran set CC=pgcc
Note that there is no
pgc++ on Windows.
PGI on Windowss requires Visual Studio. If upgrading Visual Studio (even a minor update) after installing PGI, one may need to reinstall PGI compilers.
Typically we invoke compilers from a build system such as Meson or CMake.
Meson build system supports PGI and Flang compilers.
project('demo','fortran', meson_version: '>=0.52.0') fc = meson.get_compiler('fortran') if fc.get_id() == 'pgi' message('PGI compiler') endif
project(myproj Fortran) if(CMAKE_Fortran_COMPILER_ID STREQUAL PGI) add_compile_options(-Mdclchk) endif()
select the PGI compilers at CMake configure step:
FC=pgfortran CC=pgcc CXX=pgc++ cmake -B build
PGI 19.10 ended the “pgdbg” graphical debugger. The Java-based “pgdbg” graphical debugger was for Fortran, C and C++, including the no-cost Community Edition.
