Missing separator in generated Makefile-CodePudding

I'm trying to compile this decade-old project: https://github.com/komar007/freecg

The makefile generates Makefile.dep which seems incorrectly formatted. How should I change the makefile so that the Makefile.dep gets generated correctly?

nino@nino-ubuntu:~/StudioProjects/freecg$ make
make cgl_view
make[1]: Entering directory '/home/nino/StudioProjects/freecg'
Makefile.dep:1: *** missing separator.  Stop.
make[1]: Leaving directory '/home/nino/StudioProjects/freecg'
make: *** [Makefile:10: all] Error 2

The below output shows line endings($) and tabs (^I)

Answer in the comments:

The problem seems to be echo -e. Your Make uses a shell whose echo does not recognize the -e option, so it echoes "-e" into the target file along with the rest of the text. The -e flags don't look necessary; try removing them from the dep rule, and see if that works.

CodePudding user response：

This is a very old and very badly written makefile you are trying to use. I know because I wrote it myself 12 years ago:). It requires bash, which is not the default shell GNU make chooses in many distributions. I'll fix this makefile if I have the time, but as a workaround, you can add:

SHELL=/bin/bash

at the top of the makefile to fix the problem.
