From: bpatton on 16 Apr 2008 14:41 I don't write enough makefile to be fluent, but know what sone of what can be done. I have a cadence directory that has over 5K directories. Within each directory there is a file 'layout' that is the focus of this make file. I need to have a gds file in one directory that is dependent on the layout file in another so that when the layout is newer, the rule will do a conversion. So here's what I have done: __BEGIN__ TECHNOLOGY := c014 PROCESS := C014.M DROP_ZONE := /data/phy_ver10/DROP_ZONE/${TECHNOLOGY}/${PROCESS}/drc CADENCEDB := /data/phy_ver10/regressionData/${TECHNOLOGY}/${PROCESS}/ REGRESSION FILES := ${wildcard ${CADENCEDB}/RULE_*} all : files file : ${addsuffix .gds,${FILES}} %.gds : @echo $* __END__ I get argument list too long. The names in ${FILE} have CADENCEDB in each I've tried patsubstr to remove CADENCEDB, that seemed to delete everything. What I'm after would be something like ${CADENCEDB}/%/layout : ${DROP_ZONE}/%.gds <tab>convert ${CADENCEDB}/%/layout to ${DROP_ZONE}/%.gds

This is a problem that "make" could offer you some help in avoiding. You don't say which version of "make" you are using, but it looks as if it might be GNUMake. However what you have posted would not produce the result you claim. It would probably have just reported "No rule to make target 'files' needed by 'all'". > The names in ${FILE} have CADENCEDB in each I've tried patsubstr to > remove CADENCEDB, that seemed to delete everything. > > What I'm after would be something like > > ${CADENCEDB}/%/layout : ${DROP_ZONE}/%.gds > <tab>convert ${CADENCEDB}/%/layout to ${DROP_ZONE}/%.gds You seem to have the terms reversed, and you should almost always formulate your rules in terms of "$@" "$<" and "$^". ${DROP_ZONE}/%.gds : ${CADENCEDB}/%/layout <tab> convert $< to $@ Can you post (or email, the address in the header is valid) your actual Makefile? Also the version of make you are using, and an indication if you would be prepared to change version or even program if it would solve your problem.

But I'm not sure that pure make is what you need, despite make's actions being miniature shell scripts. If you really want to stick with make, you may want to automatically generate a Makefile with one rule for each "%", perhaps using ls -f, "while read" and printf. But at that point, you almost may as well use some language that has a stat function and forget about make. Some *ix's have a "stat" command (as opposed to the stat() function I believe they all have), and I've used the os.stat() functionality in python a lot. Probably nearly all systems-programming-oriented *ix scripting languages have a stat() of some kind that you could base such a script on. I'm not sure comp.compilers is really the right place for this question. make's not really a compiler, and comp.compilers is more about -writing- compilers, than about using them. There might be a GNU make mailing list, or gnu.misc.discuss or something... if you really want to do this with pure make (aside from the miniature shell scripts that form the actions in make's pattern-action pairings). |
