Wasm build issue: undefined symbol "_main"

[AlexandreK38]

Hi!
I just tried for the first time to build my project with Wasm; but I encounter this issue:

...
[ 69%] Linking CXX executable bin/MRS2/MRS2.html
em++: error: undefined exported symbol: "_main" [-Wundefined] [-Werror]
make[3]: *** [bin/MRS2/MRS2.html] Error 1
make[2]: *** [CMakeFiles/MRS2.dir/all] Error 2
make[1]: *** [CMakeFiles/MRS2.dir/rule] Error 2
make: *** [MRS2] Error 2
build.ps1: /Users/ak/Dev/android/app-MRS2/app-axmol-utils/axmol/tools/cmdline/axmol.ps1:91
Line |
  91 |          . $build_script @sub_args
     |          ~~~~~~~~~~~~~~~~~~~~~~~~~
     | Build fail, ret=2

Any idea what could cause the issue?
Thanks for your help

Nevermind there was an issue with the CMakeFile preventing wasm main to be included in the sources
