Hi,
I met the error bellow when I run the code(cmake --build build_gtsam --config RelWithDebInfo -j).

[phamquandung]

I also have this problem when using your gtsam-1 @ToniRV

[jrpowers]

I had issues as well (but can't recall if they were the exact same). I worked around them in this PR, could you guys check if this PR works for you?

#12

[mysticalfirellama]

I am also experiencing this issue when running the code, also at the cmake --build build_gtsam --config RelWithDebInfo -j step.

I made an attempt to checkout and build #12 , that also seemed to retain this same error at this step.

A hack that is useful for me:
directly remove +stringEnd at the 48th line of NeRF-SLAM/thirdparty/gtsam/wrap/gtwrap/interface_parser/module.py

That also solves it for me, while attempting to build on Windows.

Can report that this also worked for me on a headless linux cluster

find a way to solve these two problem without change the code:

cd thirdparty/
rm -rf gtsam
git clone https://github.com/ToniRV/gtsam-1
mv gtsam-1/ gtsam

and then come back to build gtsam, and done without erro, find the way through the blog:
