foreach function

[bacpp]

hi,

I have 2 directories (../src/dir_a and ../src/dir_b) each with its own .cpp files.

I have written the following foreach function, but the problem is it is reading the .cpp files from both directories, dir_a and dir_b, to create libdir.a. Is there a way I can rewrite dirs (without hard-coding the directory names) so I can create 2 separate libraries for source files from each directory.

dirs := $(shell echo ../src/*)
find_files = $(wildcard $(dir)/*.cpp)
cppsources :=$(foreach dir, $(dirs),$(find_files)) 
cppobjects :=$(cppsources:.cpp=.o)
cppobjects:	$(cppsources)
	echo "this is the objects line"

libdir.a: cppobjects
	ar rcs $@ $(cppobjects)
	ranlib $@ */

thanks!

it sounds like you need to bifurcate your libdir.a target into libdir_a.a and libdir_b.a

and update your dependencies accordingly (including the source directory wildcards to put to dir_a and dir_b)

thx for your response kfmfe04.
so, basically, if I have 5 directories and want to create individual libraries, I'll have to hard code the libdir.a into 5 different libdir.a targets, right...

if you have that many, then maybe you'd want to change Line 1 to include all those directories - perhaps something like:

dirs := $(shell echo ../src/*/*)

if your code is in src/libdir_a/*, src/libdir_b/*, etc... and no other weird things live under src

if you do it this way, however, you will only have one target libdir.a

gotcha....thanks!
