Failure to compile SCONS in MARSS implementation

I am experiencing a problem when implementing Scons 2.5.0 in Linux Mint 17.2 (Virtually created using Virtual BOX)

Following the blog provided from the official website : http://www.marss86.org/~marss86/index.php/Getting_Started

I'm able to setup the compiling environment for Scons, but the problem occurs when i execute this command:

$ scons -Q

This results in the following error messages:

scons: *** [ptlsim/build/cache/bus.o] Error 1

g++: error: unrecognized command line option ‘-fdiagnostics-color=always’

scons: *** [ptlsim/build/cache/cacheController.o] Error 1

I have tried updating the g++ version to 5.0, but it still doesn't seem to recognize the ‘-fdiagnostics-color=always’ command.

Any ideas/help will be appreciated in this matter.

Solution

  • Simply remove the offending line 33:

    env.Append(CCFLAGS = ' -fdiagnostics-color=always ')

    from the file ./ptlsim/SConstruct. Coloured output isn't required for the build, and gcc/g++ should use a reasonable default like autofor the setting above anyway.
