Hello Xiang Xiao, Alan has approved pull
https://github.com/apache/incubator-nuttx/pull/4173 There is question what to do with SIM target and others in the longer term. I have removed them from the pull which has been merged. I resent text from previous email with correct identity to pass to the list this time and document isssues.

For example, correction of SIM target seems to be walk in the minefield. macOS (sim-02) Configuration/Tool: sim/sotest ------------------------------------------------------------------------------------ Cleaning...

So it seems that changes to other ten ARM architectures do not have purpose for now. The sim target is special It defines GCC as LD at top CC = $(CROSSDEV)cc CXX = $(CROSSDEV)c++ CPP = $(CROSSDEV)cc -E -P -x c LD = $(CROSSDEV)cc but then plain LD in MAC OS case # NuttX modules are ELF binaries. # Non-ELF platforms like macOS need to use a separate ELF toolchain. ifeq ($(CONFIG_HOST_MACOS),y) # eg. brew install x86_64-elf-gcc MODULECC = x86_64-elf-gcc MODULELD = x86_64-elf-ld MODULESTRIP = x86_64-elf-strip --strip-unneeded endif So I can add LDMODULEFLAGS += ... in else when not on MAC OS.... I have removed sim change from the pull request. Really there should be define which allows to distinguish which link slution is used and select right behavior... Best wishes, Pavel
