    scriptengine> test c4 value=ff805778 scriptStack=00000000 arg=00000000

    For some reason the stack pointer isn't pointing to the stack on Arch linux. I have no idea how that should happen. Some ideas:

    - are you messing with some other functions before this happens?
    - which compiler do you use?
    - are there maybe some security "features" in Arch linux which denies read/write/execute rights for LD_PRELOAD

    The first two lines represent the memory of cod2, the 1nd is already in libcod:

    https://github.com/kungfooman/libcod...ter/libcod.cpp

    PHP Code:
    mprotect((void *)0x080480000x135000PROT_READ PROT_WRITE PROT_EXEC); 
    0x135000 is calculated by 0817d000 - 08048000.

    Try to add this mprotect:
    PHP Code:
    mprotect((void *)0x080480000x135000PROT_READ PROT_WRITE PROT_EXEC);
    mprotect((void *)0x0817d0000xC000PROT_READ PROT_WRITE PROT_EXEC);

    It is solved now in the latest commit (1.0 support), but you need to edit doit.sh. Because now COD2_VERSION is renamed to COD_VERSION and in the doit.sh this isn't set right yet for 1.3.

    Just a heads up to anyone running cod2 server on arch linux, they just removed lib32-libstdc++5 from official packages and the one in AUR doesn't even build so just get prebuilt one from archlinux32 repo https://packages.archlinux32.org/extra/i686/libstdc++5/ you can just place it in cod2 folder or move it to your lib32.
    sudo apt-get rekt

  8. The Following 2 Users Say Thank You to voron00 For This Useful Post:

    Could you please upload the `libstdc++.so` file, Voron? I tried to download from that site but "404 Not Found"

    I still have ForeignLinux installed on Windows10 (which is Arch basically), but the `libstdc++.so`from Debian doesn't work, so I would like to test the native file.

    Thank you alot and fuck my life, IT WORKS

    Not tested with full server and libcod yet, but this looks very good:

    Arch + ForeignLinux manages what WSL can't, LOL

    I'm a bit of an Arch potato, so gonna slowly figure some stuff out... installing gcc etc.

    Code:
    [root@ForeignLinux ~]# LD_LIBRARY_PATH=. ./cod2_lnxded_1_2
    GitHub repo: https://github.com/wishstudio/flinux
