Unable to Generate 32-bit libnao_walkF.so for NAOqi Robot Using nao_walk Project

[xsan055]

I am trying to compile the nao_walk project for my 32-bit NAO robot using the NAOqi SDK (version 2.1.4.13). However, despite configuring the toolchain for 32-bit cross-compilation, the generated libnao_walkF.so remains 64-bit. My goal is to generate a 32-bit shared object file that can run on the robot.

(1)Environment Details:
-OS: Ubuntu 16.04

• Compiler: GCC 5.5.0 (with -m32 support verified)
• NAOqi SDK: Version 2.1.4.13 (64-bit)
• qiBuild version: 3.18
• CMake version: 3.16.3
• Robot: NAO H25, running NAOqi OS (32-bit architecture)

(2) Installed qiBuild and configured the cross-naoqi-sdk toolchain as follows:

<toolchain>
  <package name="libnaoqi" path="/home/sang/naoqi/naoqi-sdk-2.1.4.13-linux64" />
  <compiler>
    <binary path="/usr/bin/gcc" flags="-m32" />
    <binary path="/usr/bin/g++" flags="-m32" />
  </compiler>
</toolchain>

(3)Ran the following commands:
qibuild configure -c cross-naoqi-sdk --release --verbose
qibuild make -c cross-naoqi-sdk

(4)Verified the generated .so file:
file /home/sang/serow_ws/src/nao_walk/nao_walk_naoqi/build-cross-naoqi-sdk/sdk/lib/naoqi/libnao_walkF.so

Observed that the output indicates a 64-bit architecture:
ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, not stripped

(5)What I Have Tried
- Added `set(CMAKE_C_FLAGS "-m32 ${CMAKE_C_FLAGS}")` and `set(CMAKE_CXX_FLAGS "-m32 ${CMAKE_CXX_FLAGS}")` to the `CMakeLists.txt` file.
- Verified that `gcc` and `g++` support 32-bit compilation (`gcc -m32 -v` works correctly).
- Edited `~/qi/toolchains/cross-naoqi-sdk.xml` to include `-m32` flags.
- Installed required 32-bit libraries, including `libc6-dev-i386`.
- Checked the `CMakeCache.txt` and Makefile generated by qiBuild for `-m32` flags, but they were missing.
