Compiling doesn't create the .so file.

[ghost]

Okay so, i've tried to compile the glua-stealer. After doing cmake and make, i havent noticed the .so file appearing anywhere. How do i compile this. Im using manjaro 21.04 Everything like cmake and make is up-to-date.

[lewisclark]

It should be at the location build/src/libgluasteal.so if following the README.md instructions.

If it isn't there can you run make --debug=v and post the output here.

Thanks for fast response! i see it! okay, yet one question, why my game crashes when i inject it doe :_:"

[ghost]

Ive used linux-inject with sudo.

[lewisclark]

Are you matching up the correct architecture for everything? Garry's mod 64-bit requires the 64-bit libgluasteal.so and the 64-bit linux-inject.

[ghost]

Yes, im using x86-64 branch with chromium on gmod, the libgluasteal.so is 64-bit too, the linux-inject is 64 bit too. Ill try with the gdb inject.

Also, does the library automatically create the folder? and do i need to use sudo while injecting with GDB?

[lewisclark]

Yes, the library will automatically create ~/gluasteal. GDB needs to be run with sudo.

If you haven't found it already, here's a script that does it. The second argument must be an absolute path, not relative. Example usage: gdb_inject.sh $(pgrep gmod) /home/user/libgluasteal.so

pid=$1
lib=$2

#Credit: Aixxe @ aixxe.net
if grep -q gluasteal.so /proc/$pid/maps; then
    /bin/echo -e "\e[33mAlready injected... Aborting...\e[0m"
    exit
fi

input="$(
sudo gdb -n -q -batch \
  -ex "attach $pid" \
  -ex "set \$dlopen = (void*(*)(char*, int)) dlopen" \
  -ex "call \$dlopen(\"$lib\", 1)" \
  -ex "detach" \
  -ex "quit"
)"

last_line="${input##*$'\n'}"

if [ "$last_line" != "\$1 = (void *) 0x0" ]; then
    /bin/echo -e "\e[32mSuccessfully injected!\e[0m"
else
    /bin/echo -e "\e[31mInjection failed, make sure you've compiled...\e[0m"
fi

Ayy it works, thanks homie!

[synesthesium]

just noting that i've modified the aimtux script to do what the above script does but not requiring either pgrep or absolute paths, might be easier to use realpath is part of the coreutils so nothing needs to be installed

#!/bin/sh

pid=$(/bin/pidof $1)
realpath=$(/bin/realpath $2)

if [ -z "$pid" ]; then
    /bin/echo -e "\e[31mcould not find process by that name\e[0m"
    exit 1
fi

if grep -q $realpath /proc/$pid/maps; then
    /bin/echo -e "\e[33malready injected\e[0m"
    exit
fi

gdbcmd="$(
sudo gdb -n -q -batch \
  -ex "attach $pid" \
  -ex "set \$dlopen = (void*(*)(char*, int)) dlopen" \
  -ex "call \$dlopen(\"$realpath\", 1)" \
  -ex "detach" \
  -ex "quit"
)"

last_line="${gdbcmd##*$'\n'}"

if [ "$last_line" != "\$1 = (void *) 0x0" ]; then
    /bin/echo -e "\e[32msuccess!\e[0m"
else
    /bin/echo -e "\e[31minjection failed\e[0m"
fi

usage: ./whateveryounamedthescript.sh gmod libgluasteal.so
