背景

archlinux 默认安装的 bochs 不带 debug gui，调试程序时候需要在 bochs 手动打印寄存器及其他信息，通过 bochs 的 debug gui 可以方便查看程序相关信息。

创建 PKGBUILD 文件

mkdir bochs-enhanced-debugger
touch PKGBUILD

参考AUR (en) - bochs-gdb-stub (archlinux.org)

    make DESTDIR="$pkgdir" install
    install -Dm644 .bochsrc "$pkgdir/etc/bochsrc-sample.txt"

    cd "$pkgdir/usr/bin/"
    mv bochs bochs-enhanced-debugger
    rm bximage
    cd "$pkgdir/usr/"
    rm -rfv share
    cd "$pkgdir"
    rm -rfv etc
