[Cppunit-devel] Issues with Money example using Cygwin on Windows XP

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Dear CppUnit Developers;

I am trying to get CppUnit up and running on my machine (and hopefully
integrated with Eclipse at some point), and have had several issues in
trying to work through the Cookbook and Money example.  I'm coming from
doing Java development with Eclipse to doing C/C++, and I'd like to have
the same tools available, that is, unit testing, refactoring, etc.
Hence the interest in CppUnit with Eclipse.  However, I am a newbie to
the GNU toolchain, so please feel free to point me to where these issues
may already be documented.

Since the Cookbook example does not provide any information on
tool/envrionment setup, I switched to the Money example, and ran across
the following six issues:
=20
1.) Warnings from aclocal:

Running aclocal using the configure.in from the Money example gave the
following warnings:

   /usr/share/aclocal/libsmi.m4:8: warning: underquoted definition of
AM_PATH_LIBSMI
     run info '(automake)Extending aclocal'
     or see
http://sources.redhat.com/automake/automake.html#Extending-aclocal
   /usr/share/aclocal/cppunit.m4:4: warning: underquoted definition of
AM_PATH_CPPUNIT

I didn't know if these could be ignored or not.  It seems they can be
ignored, but perhaps either the quoting level can be fixed, or a note
added to the Money example that these warnings can be ignored.

2.) MoneyApp.cpp compile error:

   MoneyApp.cpp:1:20: stdafx.h: No such file or directory
=20
I don't have stdafx.h on my system anywhere.  Removing the line allowed
compilation to complete.  Is this line required?  Should stdafx.h be
part of Cygwin or Windows XP or CppUnit?  Perhaps a comment or
appropriate #ifdef in the code could be added?

3.) Error from g++:

Using the configure.in and Makefile.am provided in the Money example to
generate the Makefile, make check gave the following error:

   g++  -g -O2   -o MoneyApp.exe -ldl MoneyApp-MoneyTest.o
MoneyApp-MoneyApp.o =20
   /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
cannot find -ldl

I found a reference on the Internet that "-ldl" was for Linux, and could
be ignored on Cygwin.  If this is true, this should be documented on the
example page.

4.) Duplicate definition in Makefile.am?:

Following the previous issue, I noticed that MoneyApp_LDFLAGS is defined
twice in Makefile.amas shown in the example:

   MoneyApp_LDFLAGS =3D $(CPPUNIT_LIBS)
   MoneyApp_LDFLAGS =3D -ldl

Is this correct?

5.) Incorrect order of link library option?:

After removing the "MoneyApp_LDFLAGS =3D -ldl" line from Makefile.am and
rebuilding the Makefile, make check then gives a bunch of undefined
references, starting with:

   g++  -g -O2   -o MoneyApp.exe -lcppunit MoneyApp-MoneyTest.o
MoneyApp-MoneyApp.o =20
   MoneyApp-MoneyApp.o: In function `main':
   /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/ext/new_allocator.h:62:
undefined reference to
`CppUnit::TestFactoryRegistry::getRegistry(std::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)'

In looking into this, the "-lcppunit" should occur after the list of
object files.  So in the Makefile, it should be part of the LIBS
definition, not the MoneyApp_LDFLAG definition.  Is this perhaps a
problem in Makefile.am?

6.) Segmentation fault:

After tweaking the Makefile to put the "-lcppunit" after the object
files, make check completed and ran, but with a segmentation fault:

   g++  -g -O2   -o MoneyApp.exe  MoneyApp-MoneyTest.o
MoneyApp-MoneyApp.o  -lcppunit
   make[1]: Leaving directory `/home/rgould/money'
   make  check-TESTS
   make[1]: Entering directory `/home/rgould/money'

   OK (/bin/sh: line 1:  1592 Segmentation fault      (core dumped)
${dir}$tst
   FAIL: MoneyApp
   =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
   1 of 1 tests failed
   =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
   make[1]: *** [check-TESTS] Error 1
   make[1]: Leaving directory `/home/rgould/money'
   make: *** [check-am] Error 2

Note that this is using MoneyApp.cpp as first presented in the example
(minus the #include "stdafx.h") - no test fixture or tests as added
later in the example.

I am running Cygwin 1.5.18-1 (with CppUnit 1.9.14-1) on Windows XP
Professional Version 2002, Service Pack 1.

If these are legitimate issues, perhaps the Money example page can be
updated accordingly.  If it is a matter of my ignorance, perhaps adding
some notes to the Money example where other newbies can go learn the
background necessary to run the example.
