How to use CW 10.6 with external Makefile and have it work?

bobpaddock — Tue, 17 Feb 2015 13:35:33 GMT

I have jumped through all the hoops to get CW 10.6 to use my external Makefile, for KL25. This Make project builds fine when CW is not evolved.

When I do 'build all' this is the result in the console:

mingw32-make[1]: *** [build_begin] Error 1

mingw32-make: *** [all] Error 2

Is it to much to ask for CW to actually tell me what the error might be? :-(

It is not listed under the 'error' tab either.

I expect it is shell related.

The environment variable MAKESHELL is properly set so that BASH is being found, yet CW is not dealing with shell lines.

#----------------------------------------------------------------------------
# Blank line in make output spew:
$(info )
#----------------------------------------------------------------------------

#----------------------------------------------------------------------------

# If there are strange erorrs about 'f not found' this indicates that
# the MS-DOS command shell is being found rather than BASH. On
# MS-DOS/Windows set the environment variable MAKESHELL to point to
# the directory that contains BASH.

$(info SHELL = '$(SHELL)')
$(info MAKESHELL = '$(MAKESHELL)')
$(info )
#----------------------------------------------------------------------------

Results in:

SHELL = 'sh.exe'

MAKESHELL = 'J:\Apps\BASH\bin'

I'm not sure if shell lines are not executing or their results go to oblivion. Either way what CW is doing is broken:

For example:

GCCVERSION := $(shell echo `$(CC) -dumpversion`)

# ifeq "$(GCCVERSION)" "4.7.1"

# CTUNING += -mstrict-X

# else

# CTUNING += -morder1 -fno-split-wide-types -fno-inline-small-functions

# CTUNING += --combine -fwhole-program

# CDEFS += -DPROGMEM_USE

# endif

$(info )

$(info Building Target: $(TARGET_DIR)/$(TARGET) with)

$(info $(CC) version: $(GCCVERSION))

$(GCCVERSION) is not being properly filled in when run from CW.

Is there any hope here or is CW a waste of time?

Hi,

There are some interesting doc at mcuonclipse.com web site

http://mcuoneclipse.com/2012/02/13/make-my-make-with-eclipse-and-mcu10/

I don't understand exactly what is the problem.

Do you have a problem to build your application with external make file ?

don't seem to be the case ...

It seems you've problem with you perform a build under Eclipse.

There are 2 dialogs to check: Problems and Console

The second provides all info returned by all tools.

Have a great day,

Console was not showing all of the output until I enabled it to do so.

I never understand why these tools hide things by default.

Once I could see the Make output spew I understand the problem, the BASH shell sh.exe was not being found.

When I added the BASH\bin directory to my global PATH things started to compile correctly in CW.

Alas sh.exe is not found in KDS, I'll start a separate thread on that in the KDS form.
