project('shared module resolving symbol in executable', 'c')

# The shared module contains a reference to the symbol 'func_from_executable',
# which is always provided by the executable which loads it.  This symbol can be
# resolved at run-time by an ELF loader.  But when building PE/COFF objects, all
# symbols must be resolved at link-time, so an implib is generated for the
# executable, and the shared module linked with it.
#
# See testcase 125 for an example of the more complex portability gymnastics
# required if we do not know (at link-time) what provides the symbol.

link_flags = []
if host_machine.system() != 'windows'
  # Needed to export dynamic symbols from the executable
