Hi. I've been using Bison for some time to build a small language, and it
appears to give me lots of problems in conjunction with make. In order to
make my lang.c file for example, my makefile has the following lines
lang.c lang_tab.h: lang.y $(HEADERS)
bison -y -d lang.y
update y_tab.c lang.c
update y_tab.h lang_tab.h
lang.o: lang.c
...
Trouble is, make does a lot of redundant work: it runs bison twice and
consequently recompiles lang.c twice too, for some reason that escapes me.
Make was invented in order to avoid redundant compiles, but it appears to
be adding to them here. What's going on? Is there something wrong with my
makefile?
