    SubjectProblem compiling 'setup.S' in 1.3.86+
    Date
    Hello, all.  Just ran into a problem in attempting to compile the last few
    Linux kernels. Here's the log from the end of the 'make zImage':


    gcc -D__KERNEL__ -I/usr/src/linux-1.3.88/include -E -D__ELF__ -traditional -DSVGA_MODE=NORMAL_VGA setup.S -o setup.s
    as86 -0 -a -o setup.o setup.s

    make[1]: *** [setup.o] Error 1
    make[1]: Leaving directory `/usr/src/linux-1.3.88/arch/i386/boot'
    make: *** [zImage] Error 2


    I was able to successfully compile 1.3.85 but not 1.3.86 or 1.3.88. I noticed
    that 'outidx' appeared to be defined in video.S. And I've been applying the
    following patch to my kernel source to get rid of as much of the video code as
    possible.

    +#undef CONFIG_VIDEO_VESA

    ! Enable compacting of mode table
    #define CONFIG_VIDEO_COMPACT

    So it appears that 'setup.S' depends on CONFIG_VIDEO_SVGA being defined. Which
    seems flawed, IMHO. While we're on the subject, _WHY_ is all this damned video
    code in the kernel in the first place?!?! I boot up in normal 80x25 mode, and
    then use SVGATextMode to switch to 100x37. SVGATextMode is a perfectly good
    user-mode program for doing this. I really fail to see the point in including
    page after page of code in 'video.S' to detect and set modes for every video
    card on the planet. At the LEAST, there should be a compile-time option to get
    rid of this unnecessary code bloat. It'd be nice if patches like the above
    were not necessary.
