Compilation of C++ program with ACE(Adaptive Communications Environment) apis

[rstalekar]

Hi everyone,
I am Rajendra S. from India working in Bangalore and a Linux buff, who loves to work on open source projects, esp. in sourceforge.net
My programming skillsets are in C and C++, and I love to work on projects involving networking, telecom and High Availability domains.
I haven't delved into the kernel, but have a somewhat theoretical knowledge, would love to work on kernel projects.

Now to my query:-
Currently in the project which I am working on open-source, I would have to ACE i.e. Adaptive Communications Environment framework.
For this I would like to know if anyone of you have ever built a C++ program have ACE APIs in it on Linux.
If so can you please let me know how we do it.
I tried going through the document, didn't help much, I could build ACE, but not a C++ program with ACE APIs in it.

Regards,
Rajendra S.

Welcome to the forums, but I can't answer your question. You may want to move it to Linux Programming and Scripting zone.

You may want to move it to Linux Programming and Scripting zone.

Thread moved and duplicate thread deleted.

I have already posted this to Linux Programming and Scripting zone.
Thanks for the pointer.

I haven't diddled with the ACE api's for a long time, but I suspect, given your failure to provide any error messages from your attempt to compile your C++ application, that the libraries are missing the necessary 'extern "C"' directives so that the compiler doesn't apply C++ name mangling to the function names in ACE. In any case, please provide the error output from your build and I can better advise you.

Following are the errors I am facing,.
I have attached the zip file which has cpp , header and Makefile.
I tried using ACE apis writing a test program, but without a reactor, acceptor etc. just plainly using ACE_DEBUG and linked it with lACE, and went thro'' fine.
Here I am getting linker errors, following are the ones :-

When you get linkage errors like you are for undefined references, it usually means that you are not linking in required libraries. To link the ACE C++ libraries, you also need to link their C libraries, but since most of these are for C++ constructs, there are probably more than one ACE C++ library which you need to specify in your LIBS make variable.

Hi,
I am aware of that, however there are no other libraries i.e. .so which can be linked with for ACE_SOCK_Stream.
The only thing was libACE.so and libACE-5.7.1.so and therefore I am not aware what the problem could be, i will have to probably build ACE again and check.
Since u have already worked on ACE, it would be really great if you can help with the errors I am getting here.

Sorry, but the last I worked with ACE was about 10 years ago on Unix systems. I would look for the implementation of the missing pieces. It is possible that libACE.so is not the same as libACE-5.7.1.so (versionitis) and the headers you are using are for 5.7.1. FWIW, it looks like 5.7.2 is the current version. Which port are you using? And did you build it yourself from source or download binaries from somewhere?
