Hello,
i encounter "undefined reference" errors when i launch the make of the C++ request reply example v6.0.1 on Linux.
NB : I don't have any problem when i launch the make of the helloworld publish-subscribe example, every thing else being the same.
Here is the command of the example that i launch.:
hello_world_request_reply]$ make -f make/makefile_RequestReplyPrimes_x64Linux4gcc7.3.0
Here is the output: ( the french "référence indéfinie" stands for "undefined reference" )

So, does your project have a commercial support contract with RTI? It may be easier for the support team to trouble shoot this.
1) In looking over the output, I'm puzzled. Did you copy and paste this output? I see weird places where letters are missing:
connext::check_recode(DDS_ReturnCode_t, char const*, RTILogMessage const&, std::string const&, bool)
should be
connext::check_retcode(DDS_ReturnCode_t, char const*, RTILogMessage const&, std::string const&, bool)
or
connext::heck_retcode(
should be
connext::check_retcode
2) which version of the request/reply example are you compiling? From
rti_workspace\6.0.1\examples\connext_dds\c++11\hello_world_request_reply
or
rti_workspace\6.0.1\examples\connext_dds\c++\hello_world_request_reply
3) in the same command windows where you run make, if you run
g++ -v
what is the output?
Hello Howard, hello Alejandro,
We succeeded in compiling on linux the c++ hello_world_request_reply example (this one) : rti_workspace\6.0.1\examples\connext_dds\c++\hello_world_request_reply
The problem we had was that we used a g++ 7.3.1 compiler on a 7.3.0 Centos. Looking at the RTI 6.0.1 platform notes we saw that on Centos 7.x only the g++ 4.8.2 was supported. So we compiled with g++ 4.8.2 and the request_reply example did worked.
We should have looked at the core Librairies Platform Notes before !
Thank you for you help
Laurent Coyaud
Great to hear that you got it to work. Fundamentally, Connext DDS libs are built with a certain version of gcc against certain versions of libc/libc++. It's not as much dependent on the underlying Linux version (though should be the same major Kernel version, 4.x, 3.x etc).
When we say that our libs were built on a specific version of an OS, e.g., Cent OS 7.x, we usually try to use whatever version of the toolchain "comes with" that OS version. Unfortunately, if you install and try to use a newer toolchain, newer GCC...which usually also means newer libc/libc++, then that's when incompatiblities like the one you've encountered comes up.
