Question

I'm trying to compile this piece of software called Register3D_wx but have problems when trying to run make. I have installed Open GSL, Open GL and wxWidgets library as required. When I cd into the folder and run make, I get lots of error messages. I'm giving some of the output:

I know I need to edit the Makefile but that's where I am stuck. I do have some experience with makesfiles but don't know what to do. Moreover, all the dependencies are are complied and the object files produced so I don't know why ICP.cc is having this undefined reference error. The makefile is:

    #------------------------------------------------------------------------------#
# This makefile was generated by 'cbp2make' tool rev.107                       #

Answer 1

I see two potential problems here:

1. You should use wx-config --libs std,gl to link with all normal wxWidgets libraries and wxWidgets OpenGL library instead of just the latter.
2. You should ensure that in your link command LDFLAGS_RELEASE comes after the object files, this is important if you're using static wxWidgets libraries.
