Re: Better description for define?
The define construct is already in the index. I am missing an explanation there for the aspect when the construct define … endef should be used instead of the other variants for variable assignments. http://www.gnu.org/software/make/manual/html_node/Reading-Makefiles.html#index-define_002c-expansion A corresponding implementation detail might not be as obvious here for me as for other make users.

define..endef allows you to assign multi-line values to a variable.

Re: Better description for define?
Would it help a bit to mention this information explicitly in the manual? I'm not sure what you mean. If you look up define in the GNU make manual index: http://www.gnu.org/software/make/manual/make.html#Name-Index_fn_letter-D it will send you here: http://www.gnu.org/software/make/manual/make.html#Multi_002dLine which is an entire section describing this feature with examples, and titled Defining Multi-Line Variables. Now I notice that the indexes are different between the manual versions one web page and page per node. Is there any more synchronisation needed for this documentation? Would a link be nice besides the paragraph Variable definitions are parsed as follows: from the section 3.7 How make Reads a Makefile to the section 6.8 Defining Multi-Line Variables?

Extracting structured data from file names
Hello, I can generate a few file names with an approach like the following. MY_FILES::= $(foreach index,$(shell seq 2 -1 0),$(eval MY_FILES+=X$(index).txt)) all: $(MY_FILES) @echo '|$^|' $(MY_FILES): ; Now I am looking for a way to extract the number from the shown prerequisite. Can I get such encoded data by standard make and shell functions? Regards, Markus ___ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
