ddsrt_duration_to_msecs_ceil only for Windows development ?

Hi, just starting with DDS in general and with CycloneDDS in particular because it seems to be the only open DDS implementation as pure C implementation. Correct me if I'm wrong. There might be other (commercial) implementation that I had no time to investigate.

Under linux (Ubuntu 18) cloning and building is quite straight forward and I could test the examples.

Under Windows 7 it was hard to setup the environment (VSCode) to use cmake to build: I did follow your instructions using

$ cd build
$ cmake -G "Visual Studio 15 2017" -DBUILD_EXAMPLES=ON ..
$ cmake --build .

For that VSCode CMakeSettings.json had to be created and configured as

{
  "configurations": [
    {
      "name": "x64-Release",
      "generator": "Visual Studio 15 2017 Win64",
      "configurationType": "RelWithDebInfo",
      "inheritEnvironments": [
        "msvc_x64_x64"
      ],
      "buildRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\build\\${name}",
      "installRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\install\\${name}",
      "cmakeCommandArgs": "-DBISON_EXECUTABLE=C:\\ProgramData\\chocolatey\\bin\\win_bison.exe",
      "buildCommandArgs": "-v:n",
      "ctestCommandArgs": ""
    }
  ]
}

Bison was required at least in version 3.0.4 which was only available via Chocolatey.

With all that cmake --build. is still failing with:

There was no more output. I did not invest more time here since my primary intend is to use it under linux

Building worked perfectly:

$ cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=install -DBUILD_TESTING=ON  -DBUILD_EXAMPLES=ON ..
-- Linux/MacOS/QNX system found, trying to find iceoryx...
-- iceoryx not found, falling back to loopback communication.

Running the examples as well 😄

Now I wanted to go for some own development with FreeRTOS for the ARM Cortex M3 to get familiar with the API.

$ cmake CMAKE_CROSSCOMPILING=true -DCMAKE_TOOLCHAIN_FILE=ARM_CM3.toolchain -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=install -DBUILD_EXAMPLES=ON -DWITH_FREERTOS=on FREERTOS_SOURCE_DIR=~/FreeRTOS-Kernel/ ..

Without going into further details I stumbled upon a missing definition for ddsrt_duration_to_msecs_ceil !

freertos/time.c:66:26: error: inline function 'ddsrt_duration_to_msecs_ceil' declared but never defined [-Werror]
   66 | extern inline TickType_t ddsrt_duration_to_msecs_ceil(dds_duration_t reltime);

From cyclonedds/src/ddsrt/src/time/freertos/time.c it is declared as:

DDS_INLINE_EXPORT inline DWORD
ddsrt_duration_to_msecs_ceil(dds_duration_t reltime)

but not defined anywhere. It is used by void dds_sleepfor (dds_duration_t reltime) only. This is also true for windows, but not for posix and others. Since I cannot get the compilation working under windows I cannot tell anything there. 'dds_sleepfor' however is a central function although but not define for posix ?

Could you clarify a bit the differences in the platform tailorings ? What did I miss Many thanks
