Re: GBDK 3.0 - updated to latest SDCC and bank support

i did the tutorial for gbdk by gamingmonster a while back using windows and it worked. but now im using linux(debian) and i was wondering if anybody here can help me. I copy the gbdk folder to /opt/gbdk and edited the makefile in the template_minimal in the example folder to GBDK_HOME = /opt/gbdk/. when i run the makefile this is the result.

➜  template_minimal make
/opt/gbdk/bin/lcc  -o Example.gb main.c
/opt/gbdk/bin/lcc: /opt/gbdkbin/sdcc: No such file or directory
make: *** [Makefile:29: Example.gb] Error 1

so i copy the /opt/gbdk/bin to /opt/gbdkbin/sdcc and this is the result

➜  template_minimal make
/opt/gbdk/bin/lcc  -o Example.gb main.c
main.c:1:20: fatal error: /gb/gb.h: No such file or directory
compilation terminated.
main.c:1: warning 190: ISO C forbids an empty source file
make: *** [Makefile:29: Example.gb] Error 1

how do i properly setup gbdk2020 on linux? i really wana use linux as i dont have a powerful system. thanks

Re: GBDK 3.0 - updated to latest SDCC and bank support

Did you set any global environment variables? You donít need that. Looks like you have something like ďbin/sdccĒ defined.

Re: GBDK 3.0 - updated to latest SDCC and bank support

Also, installing into /opt is optional. You should be able to unzip the release anywhere, go to any included example program directory and run it's makefile. The included examples use relative path so that they should be able to just work automatically with no editing and environment variable changes required.

Re: GBDK 3.0 - updated to latest SDCC and bank support

GBDK-2020 is about to receive ability to compile for sega master system/sega game gear targets. That is not quite relevant for this forum, however, it may be of interest for people who wish to release games for several systems, not only variants of game boy. We got a bunch of interesting cross-platform examples including metasprites and large maps. As always, looking forward for your suggestions and bug reports.

Re: GBDK 3.0 - updated to latest SDCC and bank support

My virus scanning software is detecting a virus in the latest release binaries. Is anyone else getting this?

Re: GBDK 3.0 - updated to latest SDCC and bank support

that is a false positive. makebin is safe.

Re: GBDK 3.0 - updated to latest SDCC and bank support

Iím not concerned with makebin being malware (Iím sure it isnít). Iím rather concerned if I whitelist it, will there be unwanted side-effects of real malware not being recognizedÖ

that is not a problem, because you allow that exact file, not disable this type of warning.
