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 |
