i'm recompiling some c++ code for OSX and there are some bugs as the configure is not picking up some libs like atlas, pastix, etc, it should be finding either in standard path or with pkgconfig but it's not so i'm rewriting the Makefile. C++ territory is a bit of a stretch with all of the preprocessing that needs to be done then linked.
i usually use rules to keep makefiles simple but i don't know if I'll break something with my bash inside the makefile?
there are 2 binaries and a static lib as a result, each has different flags with some common source elements so the object files are renamed so they are aren't overwritten.
someone else has a better way to do this?
anyway there are a LOT of lines in the file like this which i'd like to safely reduce to rules
------------as is --------
---------- will this work ? --------
maybe it is just easier to dump the object files for each into a separate director and then use implicit rules?

FYI, it was just easier to dump the object files into separate directories and compile.
whoever thought libtool/autoconf is a good thing? i turned about 6000 lines of bloated code into about 200. compiles libraries in 1/3 the time.

cxref-cpp
cxref-cpp(1) General Commands Manual cxref-cpp(1)NAME
cxref-cpp - A modified C preprocessor to use with cxref.
SYNOPSIS
cxref-cpp ...
DESCRIPTION
To improve the output that is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
(named cxref-cpp).
This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler. In
a standard preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
not important.
With cxref-cpp, there are some features that are different to the standard GNU CPP:
Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include lines from the source
file. In version 2.8.0 and later this option is present.
Comments trailing a #include or a #define are not preserved by all versions of gcc even if the -C option is used. This is not
important while compiling, but is useful for documenting.
The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed. This
means that it includes the same default include directory paths and macro definitions. The file that contains these definitions is
called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by the -cxref-cpp-defines command line
option.
OPTIONS
The same as for gcc, apart from '-cxref-cpp-defines' described above.
