How do I set LD_PRELOAD to a process?

  • 772

I recently digged out some mods for a game called PAYDAY 2. It's called the Basic Lua Tool. After compiling, the README.md file asked me to

set LD_PRELOAD for the PAYDAY2 process to find the loader

However I have to run PAYDAY 2 through Steam so I can't just go into the Terminal and run the process payday2_release. How do I force Steam to use the payday2_release with LD_PRELOAD? I also don't know the syntax for LD_PRELOAD so please help.

Source for the BLT (GitHub): https://github.com/blt4linux/blt4l

Loader is called libblt_loader.so

    Found it. According to the file blt4l_1.3_Ubuntu-precise-steamrt on the website https://github.com/blt4linux/blt4l/releases/ there is already a prebuilt libblt_loader.so (wasted 2 weeks compiling this) and a README.md saying

    Move the contents of this folder in to your PAYDAY 2 folder, so that it looks like this:

    PAYDAY 2/
    mods/
    libblt_loader.so

    Open Steam, and open the properties for PAYDAY 2. Select "Set Launch Options", and set it to:

    env LD_PRELOAD="$LD_PRELOAD ./libblt_loader.so" %command%

    If your PAYDAY 2 folder is in a different library folder, change the path accordingly.
