Build Error for ns-3-vr-app with ns-3.37

[Nori]

I am trying to build the ns-3-vr-app module from signetlabdei/ns-3-vr-app, which is stated to be compatible with ns-3.37. I have followed the installation instructions, but I encounter a build error.

System Information:

• OS: [Ubuntu 22.04 LTS]
• ns-3 Version: ns-3.37
• Build System: CMake with Ninja
• Compiler Version: [Output of g++ --version]

Error Message:

During the build process, I receive the following errors:

Modules that cannot be built:

You cut out the important parts of the log which contained the error cause. So I can't help.

You need to set NS3_PRECOMPILED_HEADERS to OFF, and then reconfigure.

thank you for your replay, other error shows

[Gabriel Ferreira]

add_library ALIAS requires exactly one target argument.

refers to https://gitlab.com/nsnam/ns-3-dev/-/blob/ns-3.37/build-support/custom-modules/ns3-module-macros.cmake#L94

No idea why it is failing. You can try removing this line.
