Error making Guzunty loader

[MrEngman]

I'm going through the "Get your Pi set up" page on the wiki. When I try to make the Guzunty loader I am receiving an error running make.

make
gcc -o gz_load -Wl lenval.o micro.o ports.o -L/usr/local/lib -lbcm2835 -lrt
gcc: error: unrecognized command line option â-Wlâ
make: *** [gz_load] Error 1

Anyone any idea why? gcc version 4.7.2

Hmm, I haven't tried this yet, but at first glance the switch should be -Wall, not -Wl.

The make file on github looks ok, so maybe the file got corrupted locally?

Try 'git status' to see if git thinks anything got changed.

Correction, the makefile does specify -Wl in the final link stage.

It runs fine under gcc-4.6, which is the raspbian default compiler at this time.

Please let me know if you need to use gcc-4.7 and I will investigate more deeply. Raspbian does support gcc-4.7, but it is not the default.

[campbellsan]

I looked a little deeper anyway, and confirmed that the error message is specific to gcc-4.7.

I removed the -Wl option from line 30 of Makefile and gz_load builds and runs fine.

I will wait to change the github Makefile until gcc-4.7 becomes the Raspbian default.

Thank you for noticing this :-)

Thanks, I edited Makefile and changed -Wl to -Wall, as it appears in line 8 of the file, and I got it to compile OK as well with that change. Finished setting up my Pi and ran the test on Guzunty and it all looks good. A really neat little add-on.

Just to explain why I'm using gcc-4.7. I updated to gcc-4.7 quite a long time ago as raspbian is compiled using gcc-4.7 and I compile several wifi modules not included in the standard image and they do not work correctly if compiled using gcc-4.6.

Thanks for all your efforts.

[campbellsan]

Aha! I knew there would be a reason. :-)

Thanks for the kind comments on the Guzunty, we put a lot of thought into it.

I'm delighted you're off and running, if you wish, please do let us know what you're doing with it.
