Hi,
I'm trying to build pjsip for nios2 target. I've
added nios2 to config.sub and pjlib/include/pj/config.h. It compiles
without error. But
I want to add a link option -elf2flt to get a bflt format executable. I
create a file build/m-nios2.mak.
export M_CFLAGS := $(CC_DEF)PJ_M_NIOS2=1
export M_CXXFLAGS :=
export M_LDFLAGS := -elf2flt
export M_SOURCES :=
but it still produces ELF executables. Do I miss something here?
I find it ok to add a line in user.mak
export LDFLAGS += -elf2flt
and it works as I expect.
I just want to know why the first method doesn't work. Thanks.
below is the changes I made
