PR-1890 (commit 2caf3a69e3d60ec550980f7ba897c732e7a39df7) attempts to speed up compilation time for concurrent builds by changing assignment to makefile variables CFLAGS, CPPFLAGS, CXXFLAGS, and AFLAGS from recursive (=) to simple (:=). This causes these compile options to be expanded only once during the build.
If you are using NuttX on a custom board not in the NuttX repository, you may want to make a similar change to your Make.defs files. Change these recursive assignments:
CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe CXXFLAGS = $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe CPPFLAGS = $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) AFLAGS = $(CFLAGS) -D__ASSEMBLY__ |
to simple assignments:
CFLAGS := $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe CXXFLAGS := $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe CPPFLAGS := $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) AFLAGS := $(CFLAGS) -D__ASSEMBLY__ |
PR-2192 (commit 9208176f600d0d04446531909bf05710716a5ee4) refactors definition of the __NuttX__ preprocessor symbol to tools/Config.mk, so it is no longer necessary to define it in each board's Make.defs file.
If you are using NuttX on a custom board not in the NuttX repository, you may want to make a similar change to your Make.defs files.
Remove lines like this:
ARCHDEFINES = -D__NuttX__ |
Or remove -D__NuttX__ from lines like this:
CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__ |
