seabios compilation error

[SangpilKim]

Hi, I'm seeing the following error while executing kvm-qemu.sh script in ubuntu 18.04.2. This error happens on executing seabios_func. I guess makes the problem. Please let me know how to fix the problem.

i was able to reproduce that looks like if you don't replace that happens

did you replace ?

Thank you for the fast response.

No, I just ran kvm-qemu.sh as is.

seabios_func() runs seabios compilation (make -j"$(nproc)") twice as below. The problem happens in the second seabios compilation. No error is found in the first compilation returns success.

function seabios_func() { cd /tmp || return fail=0 echo '[+] Installing SeaBios dependencies' apt-get install git iasl -y if [ -d seabios ]; then rm -r seabios fi if git clone https://github.com/coreboot/seabios.git; then cd seabios || return if declare -f -F "replace_seabios_clues"; then replace_seabios_clues else replace_seabios_clues_public fi # make help # make menuconfig -> BIOS tables -> disable Include default ACPI DSDT # get rid of this hack make -j"$(nproc)" 2>/dev/null # Windows 10(latest rev.) is uninstallable without ACPI_DSDT # sed -i 's/CONFIG_ACPI_DSDT=y/CONFIG_ACPI_DSDT=n/g' .config sed -i 's/CONFIG_XEN=y/CONFIG_XEN=n/g' .config echo"+++++++++++++++++++++++" if make -j "$(nproc)"; then echo '[+] Replacing old bios.bin to new out/bios.bin' bios=0 FILES=( "/usr/share/qemu/bios.bin" "/usr/share/qemu/bios-256k.bin" ) for file in "${FILES[@]}"; do cp -vf out/bios.bin "$file" bios=1 done if [ $bios -eq 1 ]; then echo '[+] Patched bios.bin placed correctly' else echo '[-] Bios patching failed' fi else echo '[-] Bios compilation failed' fi cd - || return else echo '[-] Check if git installed or network connection is OK' fi }

The first compilation shows:

[doomedraven]

yes it shoudl compile twice ;)

if you read your error

out/src/fw/ssdt-misc.dsl.i     65:             Name(_HID, "<WOOT>")
Error    6002 -            String must be entirely alphanumeric ^  (<WOOT>)

you didn't replace in script is why it fails to you, you need to replace them for seabios and qemu if you building malware analysis related setup

[SangpilKim]

Thank you for your feedback.

I'm sorry that I couldn't get your point exactly. Please let me know how to replace. I thought two functions in your script, replace_qemu_clues_public and replace_seabios_clues_public, were already playing the role, so I just executed the script as "sudo ./kvm-qemu.sh all".

did you solve it?
