[rabbitmq-discuss] regarding SimpleAmqpClient

Thu Mar 8 16:37:31 GMT 2012

Dear expert,
As I told you yesterday I'm working on a C++ application who uses RabbitMQ. I have a simple question for you: related to Channel.h, function BasicConsume() I read in the function comments
"Note: due to a limitation to how things are done, it is only possible to reliably have a single consumer per channel, calling this more than once per channel may result in undefined results from BasicConsumeMessage"
Is it something related only on the C++ implementation?

Last but not least, I think there are some mistakes in the example simple_connect.cpp

1.      #include <SimpleAmqpClient.h> should be #include < SimpleAmqpClient/SimpleAmqpClient.h> since the installation procedure copies that file in the SimpleAmqpClient folder;

2.      BasicMessage::ptr_t msg_out = channel->BasicConsumeMessage(); doesn't work for two reasons:

a.      A function BasicConsumeMessage() which takes no argument doesn't exist in Channel.h;

b.      The function BasicConsumeMessage(...) currently defined in Channel.h returns a Envelope::ptr_t, not a BasicMessage::ptr_t.

3.      Header file SimpleAmqpClient.h includes unistd.h which is a POSIX header. I had to comment that row in order to make things work in Visual Studio 2008.

Best wishes,

Lorenzo

Oggetto: Re: [rabbitmq-discuss] how to build SimpleAmqpClient?

Did you build boost as a set of static libraries?  If so you'll need to set the Boost_USE_STATIC_LIBS=ON CMake variable.

Another note: given you're building with VS2008 you're going to run into a different problem once you get past the boost library issue you're having: see this  https://github.com/alanxz/SimpleAmqpClient/issues/1 for what the issue is and a workaround.

Dear Experts,
I'm trying to build SimpleAmqpClient (v2.0-beta-2) in Windows (VS 2008), but when I execute CMake, there are errors regarding boost:

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindBoost.cmake:1128 (message):

Unable to find the requested Boost libraries.

Boost version: 1.48.0

Boost include path: C:/Applicazioni/boost

The following Boost libraries could not be found:

boost_chrono

boost_system

No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the

directory containing Boost libraries or BOOST_ROOT to the location of

Boost.

Call Stack (most recent call first):

CMakeLists.txt:8 (FIND_PACKAGE)

I add manually the filepath for chrono and system to Boost_Chrono_Library_Debug, Boost_Chrono_Library_Release, Boost_System_Library_Debug, Boost_ System_Library_Release, but still it doesn't find anything. I also create the BOOST_ROOT but still it doesn't work.
Any suggestion?

Best,

Lorenzo
