Hi All
I implemented auto-dependencies after reading Paul's article, but as
number of .d files generated grows, performance drops. So I try to find
out where can I win those msecs. After make -d:
...
Reading makefile `../db/db.mk' (search path) (no ~ expansion)...
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
Got a SIGCHLD; 1 unreaped children.
...
What do all these SIGCHLDs mean? ~ expansion?
Are there any thumb-rules regarding make performance?
as I tried to launch make -r other problem arised. Following rule chain
doesn't work anymore, ie. touching .x files did not result in a rebuild:
%_xdr.c: %.x
...
%_$(OBJ_CODE).o: %.c
...
$($(MODULE)_LIB): $($(MODULE)_LIB)($($(MODULE)_OBJS))
