Thanks, David! I have no interest in running pgen on the target/host. My only
interest is building python and its various modules to run on my embedded host.
I do not want to develop Python on the embedded host. Unfortunately, the
build process requires Parser/pgen to build the grammar files, which are needed
for several object files. Here's the relevant snippet from the Makefile.pre.in:
$(GRAMMAR_H): $(GRAMMAR_INPUT) $(PGENSRCS)
@$(MKDIR_P) Include
$(MAKE) $(PGEN)
$(PGEN) $(GRAMMAR_INPUT) $(GRAMMAR_H) $(GRAMMAR_C)
$(GRAMMAR_C): $(GRAMMAR_H) $(GRAMMAR_INPUT) $(PGENSRCS)
$(MAKE) $(GRAMMAR_H)
touch $(GRAMMAR_C)
$(PGEN): $(PGENOBJS)
$(CC) $(OPT) $(LDFLAGS) $(PGENOBJS) $(LIBS) -o $(PGEN)
Parser/grammar.o: $(srcdir)/Parser/grammar.c \
$(srcdir)/Include/token.h \
$(srcdir)/Include/grammar.h
...
Python/compile.o Python/symtable.o Python/ast.o: $(GRAMMAR_H) $(AST_H)
If there is a way to eliminate the need for Parser/pgen to run on the build
system to cross-compile the default "all" target, that would be great. ... I'll
experiment with "make touch". ... Thanks!
