Hello,
I have downloaded qpid-cpp-0.6. Make / make intall works but make check will
fail (Please see following output of make ckeck). As i can see the -Werror
option is on, so i dont understand the line "cc1plus: warnings being treated
as errors".
I believe that if a warning is generated, then it is normal for the
compiler to state that warnings are being treated as errors on the first
occurrence if the -Werror option is set.
Furhtermore I have noticed that the following test examples are missing ( I
am looking for them in src/tests as described in
https://svn.apache.org/repos/asf/qpid/trunk/qpid/cpp/examples/README.txt) :
# ./direct_producer
# ./listener
# ./server
# ./client
These examples are located in the cpp/examples directory, not
cpp/src/tests. I cannot find in the README file above (at least in the
latest version on trunk) where the tests directory is mentioned. The
examples are built as part of "make check"; it is possible that the
error you are experiencing below may stop the build before it gets to
the examples.

It might be helpful if you could tell us which distribution you are
using, and what the compiler version is.
It looks on the face of it that your compiler is tuning on a
"warn_unused_result" warning check - possibly as part of the -Wall flag
which is set during configure, and this is picking up these two lines in
the qrsh_server.cpp file - which do indeed ignore the result of two
system calls, and should be fixed at some point. I would see if you can
override that particular warning flag, or turn off the -Werror flag -
that should get you a compile you can use.
Adding a (void) cast before the calls should silence the compiler. If that does
the trick attach a patch to a JIRA and we can commit it.
