Makefile
 

Hi,

This is very simple question. I searched Google but could not find the answer.

I have a number of source files like:

file_1.cxx, file_2.cxx, .........., file_40.cxx .
To compile all files, I can write (in Makefile):
SOURCE = $(wildcard *.cxx)

But I want to compile only selected files like from file_11.cxx to file_22.cxx. I tried this (as in linux command line):

SOURCE = $(wildcard *_[11-22].cxx)

But it is not working. Any idea will be greatly appreciated.

Also, I noticed that only on digit inside [] in recognized in linux command line. I.e., if I write file_[0-9].cxx, then it will be fine but if I write file_[11-20].cxx, it will not recognized.

Thanks.

syntax you are currentry using means
file_1.cxx -or-
file_2.cxx -or-
file_-.cxx -or-
file_0.cxx

because a set of characters between brackets is interpreted as match any of those characters

for documentation on this specific feature of make I would suggest

http://www.gnu.org/software/autoconf...Wildcards.html

otherwise a simpler alternative would be to use another naming scheme for you source files
like source_includethisone_1.cxx source_dontincludethisone_2.cxx

Thanks.
