8018X system: bell-8254.c:24:14: error: ‘SPEAKER_PORT’ undeclared

make for 8018x system breaks in:

In file included from bell-8254.c:12:0: bell-8254.c: In function ‘soundp’: bell-8254.c:24:14: error: ‘SPEAKER_PORT’ undeclared (first use in this function) outb(inb(SPEAKER_PORT) | 0x03, SPEAKER_PORT);

not sure if the make rule is correct or not: ./elks/arch/i86/drivers/char/Makefile

ifdef CONFIG_CONSOLE_DIRECT OBJS += console-direct.o bell-8254.o endif endif

The reason this fails is that the Direct Console (that is, direct access to video RAM via CGA/EGA mode in IBM PCs) isn't supported in the 8018x build. The 8018x port uses the headless console (CONFIG_CONSOLE_HEADLESS).

Are you building this for a 8018X-based system that requires support for IBM PC-style text video modes?

I just select the generic 8018x system.

may be i am doing something wrong. selecting system 8018x in make menuconfig, does not allow any additional settings besides INTx and RTC.

selecting system 8018x in make menuconfig, does not allow any additional settings besides INTx and RTC.

Thanks, I'll take a look at this. The 8018X port doesn't allow much configuration, but selecting it should not cause a compilation error.
