Hi,
I've discovered some odd behaviour with make v3.79.1 as included with the CygWin
development tools package. I've searched the web and checked the make manual, but have
not been able to find anything helpful so far.
When calling ccppc (a PowerPC cross-compiler supplied as part of the Tornado VxWorks
Development Tools from WindRiver) via make, any error messages generated by ccppc do
not get printed. Any error messages I would expect to be printed via STDERR do not get
printed.
I have tried calling gcc instead of ccppc and saw all expected error messages. I also
tried using a different version of make (v3.74 as shipped with Tornado 2.2) with both
ccppc and gcc. In both cases I saw the expected error messages.
It is only the combination of make 3.79.1 (from Cygwin) and ccppc that appears to
suffer from this issue. Naturally, this is the combination of tools I require. ;-)
The make file I am using contains the following:
---------------------------------------------------------------------------
MY_PPC_COMPILER = ccppc
MY_GNU_COMPILER = gcc
ifeq ($(FOR_PPC), 1)
COMPILE = $(MY_PPC_COMPILER)
else
COMPILE = $(MY_GNU_COMPILER)
endif
all :
$(COMPILE) -c -o client.o client.cpp
---------------------------------------------------------------------------
Note that the source file being compiled does not exist. This should thus produce a
file not found error.
The script I am using to call make issues the following commands:
---------------------------------------------------------------------------

No additional output is printed to the console window.
As shown by the log file, the expected errors are not printed when ccppc is called
from make 3.79.1. My suspicion is that this a problem with make, though it's quite
possible that this is a ccppc issue, or perhaps a problem with both make and ccppc. I
have verified that the error output from ccppc is printed via STDERR. Interestingly,
the output from gcc is also printed via STDERR.
I'm using Windows 2000 with SP4, though I have seen the same problem with SP3 as well.
I have tried using the version of ccppc shipped with multiple versions of Tornado
(v2.0, v2.02, v2.1, v2.2, v2.2.1) and saw the same missing output with all versions.
The version number for my copy of cygwin1.dll is "1.3.22-dontuse-21".
Any assistance would be most appreciated.
Thanks,
Chris Whitehead
