…ctories add_sourcekit_default_compiler_flags was invoking _add_variant_link_flags and getting link flags but not actually using the link_libraries or library_search_directories. In android builds, this means that the correct libc++ is not being linked against.
…ectories
The CMake variables ${sdk} and ${arch} are only set if
_add_variant_link_flags is invoked from add_swift_target_library calling
_add_swift_library_single. If you get to _add_swift_library_single from
add_swift_host_library, those variables will not be set and subsequent
linking will not find ICU libraries. This was an issue when building
swift host libraries on Android.

There was a problem hiding this comment.
I think it would be nicer if we sink the if (NOT ${SWIFT_ANDROID_NDK_PATH} STREQUAL "") into the case, as an always thing.
if(swift_build_android AND NOT ${SWIFT_HOST_VARIANT_SDK} STREQUAL ANDROID)
if("${SWIFT_ANDROID_NDK_PATH}" STREQUAL "")
message(FATAL_ERROR "SWIFT_ANDROID_NDK_PATH must be set to the Android NDK path")
endif()

Umm, why was this merged when there's a more comprehensive Android pull, #23208, that's been waiting for weeks now? |
