I'd like to call a executable which works fine on terminal if called within the bin directory otherwise it give missing issues. To archive the same on my D program, I did set the working dir but I get an error saying a .so file couldn't be found. What am I missing here?

    enum app = "/path/to/wkhtmltox-0.12.4_linux-generic-i386/wkhtmltox/bin/wkhtmltopdf";
    enum html = "/path/to/my/htmlFile.htm";
    enum pdf = "/path/to/output/foo.pdf";
    // is this the correct working dir?
    enum workingDir = "/path/to/wkhtmltox-0.12.4_linux-generic-i386/wkhtmltox/bin";
    import std.process : execute, Config;
    auto conv = execute([app, html,pdf],
                        null,
                        Config.none,
                        size_t.max,
                        workingDir);
    writeln(conv);

Gives the error:

Tuple!(int, "status", string, "output")(127, "/path/to/wkhtmltox-0.12.4_linux-generic-i386/wkhtmltox/bin/wkhtmltopdf" error while loading shared libraries: libXrender.so.1: cannot open shared object file: No such file or directory\n")

Maybe the terminal and your utility you run wkhtmltopdf from have different environment?

I guessed so, I've tried set the env as well:

    enum env = ["LD_LIBRARY_PATH" :
    "/path/to/wkhtmltox-0.12.4_linux-generic-i386/wkhtmltox/lib"];
	import std.process : execute, Config;
	auto conv = execute([app, html,pdf],
                        env,
						Config.newEnv,
						size_t.max,
						workingDir);
but that doesn't work either.

My assumption is, the issue is not related to D or the working dir. It is more a linux thing. Maybe you also try function executeShell. Also did you have a look e.g    here

Also did you try, just this command?
auto conv = execute([app, html,pdf]);

As you use absolute paths, the working directory is not relevant.

You're right, it's a linux issue. I did get rid of the binaries I've had and compile from the source code on my own, just passing the aditional LD_LIBRARY_PATH set to where the .so files were located, it worked fine!
