# The test represents the order-related issue that we have with the ld linker.
|
|
#
|
|
# CMake versions < 3.21.0 produce the following linker line:
|
|
# <binary_name> main.cpp -o static_link_order_test libstaticLib.a objlib.cpp.o
|
|
# Since 'static_link_order_test' doesn't have direct use of 'staticlib2.cpp.o' symbols
|
|
# the translation unit is not linked. When we link objlib.cpp.o it cannot resolve symbols from
|
|
# staticlib2.cpp.o.
|
|
#
|
|
# For now it's only applicable for ld-like linkers. 'lld' has no such issue.
