Gameboy Development Forum

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

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.

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.

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

I’m not concerned with makebin being malware (I’m sure it isn’t). I’m rather concerned if I whitelist it, will there be unwanted side-effects of real malware not being recognized…
