Summary

0015460: PGI Fortran compiler does not recognise -fPIE

Description

By selecting POSITION_INDEPENDENT_CODE the PGI compiler settings add automatically the flag -fPIE.
This flag does not exist for PGI Fortran Compiler.
I have checked this with pgf77, pgf90 and pgfortran.

The only workaround I found is to set the flag:

-DCMAKE_Fortran_FLAGS="-noswitcherror"

This turns off the check for flag validity in the compiler, but obviously is not a long-term solution, since now any test to compiler flags will pass irrespectively if the flag is recognised or not.

The solution I think is changing Modules/Platform/Linux-PGI.cmake to:

set(CMAKE_${lang}_COMPILE_OPTIONS_PIE "")

Note that the flag -fPIE also does not exist for PGI C and C++ compilers.

Steps To Reproduce

Build the attached CMakeLists.txt project with

cmake -DCMAKE_Fortran_COMPILER=pgf90 ..

Additional Information

I am using CMake 3.1.2 and PGI Fortran 14.4.
The man page of compiler does not reference this flag whatsoever.
This is the output I get:

-- The C compiler identification is GNU 4.8.1
-- Check for working C compiler: /usr/bin/gcc
