nstallation issue with GWmodel3 from source – missing libgwmodel submodule

[nikosGeography]

Hi,

I am trying to install GWmodel3 from the source repository on my Linux system, but the compilation fails because the libgwmodel submodule is missing.

$  inxi -Sxxx
System:
  Host: Lenovo-Z50-70 Kernel: 6.17.0-35-generic arch: x86_64 bits: 64
    compiler: gcc v: 13.3.0 clocksource: tsc
  Desktop: MATE v: 1.26.2 wm: marco v: 1.26.2 with: mate-panel
    tools: mate-screensaver vt: 7 dm: LightDM v: 1.30.0
    Distro: Linux Mint 22.3 Zena base: Ubuntu 24.04 noble

Already installed dependencies GSL, sf and RcppArmadillo when I created the R project I am working on, many months ago.

What I did

1. Downloaded GWmodel3-master.zip from GitHub.
2. Unzipped into my R project folder that uses renv.
3. Ran R CMD build GWmodel3-master → the DESCRIPTION was OK, but the build process failed with:

make: *** No rule to make target 'libgwmodel/src/gwmodelpp/spatialweight/BandwidthWeight.cpp', needed by '.../BandwidthWeight.o'. Stop.
ERROR: compilation failed for package ‘GWmodel3’

I checked the unzipped folder and confirmed that libgwmodel is missing.
The .gitmodules file exists, but the submodule content is not included in the ZIP archive.

I also tried to install the package using pak,same issue.

that's the output of the console when using remote::install_github()
