Linking Recording service library statically

Hi,

I'm experiencing with the service_as_library example for Recording Service from here: https://github.com/rticommunity/rticonnextdds-examples/tree/master/examples/recording_service/service_as_lib/cpp

In my case, I'd like to link all the RTI Connext libraries to the executable statically, so I've made some changes to CMakeLists.txt provided by the example. Here's my modification:

diff --git a/examples/recording_service/service_as_lib/cpp/CMakeLists.txt b/examples/recording_service/service_as_lib/cpp/CMakeLists.txt
index 4a96de20..342568d6 100644

However, I still meet build errors when compiling the code with these modifications. The make log is in attached file. I'm using RTI Connext Pro 6.0.1 on Ubuntu 18.04.

Please help. Thanks in advanced.

From the errors, I would guess that your CMAKE configuration isn't pulling in the required compiler macros, such as RTI_UNIX, need to configure the header files to build for Linux or Windows or etc.

You can look through the file

rti_connext_dds-6.0.1\resource\cmake\FindRTIConnextDDS.cmake

to see how you may want to modify the CMakeLists.txt to add the definitions.  Maybe adding:

 add_definitions("${CONNEXTDDS_COMPILE_DEFINITIONS}")

is sufficient.
