Default compiler flags used by devtools.

These default flags enforce good coding practice by ensuring that CFLAGS and CXXFLAGS are set to -Wall -pedantic. These tests are run by cran and are generally considered to be good practice.

Usage

compiler_flags(debug = FALSE)

Arguments

debug

If TRUE adds -g -O0 to all flags (Adding FFLAGS and FCFLAGS)

Details

By default compile_dll() is run with compiler_flags(TRUE), and check with compiler_flags(FALSE). If you want to avoid the possible performance penalty from the debug flags, install the package.
