executable

Using the readlink function used as a solution to How do I find the location of the executable in C? , how would I get the path into a char array? Also, what do the variables buf and bufsize represent and how do I initialize them? EDIT: I am trying to get the path of the currently running program, just like the question linked above. The answer to that question said to use readlink("proc/self/exe") . I do not know how to implement that into my program. I tried: char buf[1024]; string var = readlink("/proc/self/exe", buf, bufsize); This is obviously incorrect. This Use the readlink() function

SWT comes with a base JAR and one specific JAR per platform (Windows, Linux/32bit, Linux/64bit, Mac, AIX, ...). How can I create an executable JAR that will select the correct platform JAR at runtime? [EDIT] I was thinking to supply all platform JARs in a subdirectory and in main() would then modify the class loader. Has anyone already tried this? Matías Look at this, there is a code sample: Create cross platform java swt application For my current job I needed to supply an executable jar that could load jars inside itself and execute a second main(). Basically a bootstrap main() and an

I want to create one executable JAR file which contains other JAR libraries. But when I execute the JAR, it gives an error of class path problem. How do I solve the class-path problem? Tony I think you can try it like this; Here is a simple example for you question. First, we assume we have a project directory like D:\javademo . In this working directory we then create a main class HelloWorld.java and thtat contains our other JAR files, like commons-lang.jar . Now, we must archive our main classes HelloWorld and commons-lang.jar into test.jar file. First we must edit our manifest file so that

I have some .py files I wrote that I want to run on a different machine. The target machine does not have python installed, and I can't 'install' it by policy. What I can do is copy files over, run my stuff, and then remove them. What I tried was to just take my development python folder over to the target machine and cd to the python folder and run python.exe /path/to/.py/file . It gave me an error saying that python.dll was not registered. If I registered the DLL that is probably going to move me to far across the 'violating policy' line. Is there anyway I can accomplish running python files

People also often ask "How can I compile Perl?" while what they really want is to create an executable that can run on machines even if they don't have Perl installed. There are several solutions, I know of: perl2exe of IndigoStar It is commercial. I never tried. Its web site says it can cross compile Win32, Linux, and Solaris. Perl Dev Kit from ActiveState. It is commercial. I used it several years ago on Windows and it worked well for my needs. According to its web site it works on Windows, Mac OS X, Linux, Solaris, AIX and HP-UX. PAR or rather PAR::Packer that is free and open source. Based

I'm trying to compile an executable (ELF file) that does not use a dynamic loader. I built a cross compiler that compiles mips from linux to be used on a simulator I made. I asserted the flag -static-libgcc on compilation of my hello.cpp file (hello world program). Apparently this is not enough though. Because there is still a segment in my executable which contains the name/path of the dynamic loader. What flags do I use to generate an executable which contains EVERYTHING needed to be run? Do I need to rebuild my cross compiler? Try using the -static flag? Use the following flags for linking

Is there any real use for self modifying code ? I know that they can be used to build worms/viruses, but I was wondering whether there is some good reason that a programmer may have to use self modifying code. Any ideas? Hypothetical situations are welcome too. Turns out that the Wikipedia entry on " self-modifying code " has a great list: Semi-automatic optimization of a state dependent loop. Runtime code generation , or specialization of an algorithm in runtime or loadtime (which is popular, for example, in the domain of real-time graphics) such as a general sort utility preparing code to
