I am trying to compile the old PR2 libraries to run on ROS on Windows 10 with Visual Studio 19.

One of the dependencies ivcon fails to compile giving the following error:

LINK : fatal error LNK1104: cannot open file 'm.lib

I searched for an answer and I understand the main issue is one of C programs calling for m.libthat is not present. I tried to replace the library named 'msvcrt' with m as suggested: https://stackoverflow.com/questions/3... but it didn't work.

Appreciate to get any advise on how to solve this issue. Thank you in advance.

After some digging, removing m.lib from LINK_LIBRARIES located in the build.ninja file in the build folder fixed the problem, and I was able to compile successfully.
