Gem I wrote not executable on linux, but seems to work on windows
I replaced spec.executables = spec.files.grep(%r{^bin/}) { |f| File.basename(f) } with spec.executables = ["getDartPortalAndInitBuild"] And now it functions. I am not sure why the rake install worked correctly, but there it is.

Windows executable with linux shell script inside
A Linux shell script should start with #!. A Linux ELF executable should start with x7FELF. If a Windows executable cannot start with these bytes your dream is not possible. I believe that PE (the binary format of Windows executable) cannot start with these (but I am not sure). Hence your universal installer single file is an impossible dream. On Linux, you could consider playing with binfmt_misc or shar. Read Levine's Linkers and Loaders book, and elf(5) & execve(2) Linux man pages.

Unknown file permissions for executable bit - Linux
What's unknown about them? From the ls man page: The next three fields are three characters each: owner permissions, group permissions, and other permissions. Each field has three character positions: 1. If r, the file is readable; if -, it is not readable. 2. If w, the file is writable; if -, it is not writable. 3. The first of the following that applies: S If in the owner permissions, the file is not exe- cutable and set-user-ID mode is set. If in the group permissions, the file is not executable and set-group-ID mode is set. s If in the owner permissions, the file is exe- cutable and set-user-ID mode is set. If in the

What are the alternatives to Windows security subsystem in .NET winforms applications
Once I worked in a WinForm application which was supposed to run on intranet, each user would log into the application....and this application was using centralized web service to authentication and other CRUD operation....The service was mediator between WinForm app and DB. The approach given in code project article which u mentioned in question...is also fine. Anyway I also got curious here....As you said u are about to start development in .Net 4.0 Winform.....I would like to understand why you made this choice over WPF? What reasons u got to favor WinForm in your scenario ?

Exec(Linux). How it functions internally? Linux executable attributes(rlimit)
The RLIMIT_CORE is used to place a limit on the amount of info that coredump is allowed to produce, before it is aborted. Once this limit is hit, no more info is logged and the message Aborting Core is logged to the console. From the man page of core : A process can set its soft RLIMIT_CORE resource limit to place an upper limit on the size of the core dump file that will be produced if it receives a "core dump" signal. Use setrlimit() to configure RLIMIT_CORE to a larger value to obtain complete coredumps. The most common format of executables/shared-objects is ELF. On Linux, the dynamic loading and linking of these shared-objects is performed by ld.so ld.so is loaded in the address space of a newly created process (by exec in this case) and executed first. This is possible as

Linux/Unix - Setting default file/folder permissions using ACL, executable permission not setting?
It's not setting the execute bit because files are only created with execute permission if the application explicitly requests it. Since it makes no sense to make an .html file executable, whatever program created it did not request execute permission to be added, so it has no execute permission. Consequently, execute permission from the default ACL effectively only applies to directories, not to files. As for why the default group is not set to ftp, this is more subtle. The default ACL is just that -- an ACL. It's not a default group ownership. As such it shows up not in ls but in getfacl: # mkdir public # setfacl -R -m u::rwx,g:ftp:rwx,d:g:ftp:rwx,o::rx public/ # getfacl public # file: public # owner: root # group: root user::rwx group::r-x group:ftp:rwx mask::rwx other::r-x defa

Eclipse - Common Preference settings file(.epf) for Linux and Windows
No, because JAVA_HOME could point to, well, anything--1.3, 1.7, who knows? You want complete and conscious control over what's in a project's Java Build Path and complete isolation from the OS if you want your projects to be portable. It's ok to have the preferences refer to things unique to the machine, you can change those on other machines, it's the settings in the projects that you don't want tied a specific machine. Start by setting their Java Build Path to use an Execution Environment to find its JRE.

Write C++ on Windows but use Linux System calls through a Linux emulator
You've already tagged your question with Cygwin. That seems like the best solution for what you want. Cygwin is basically a collection of programs which emulate a GNU/LInux environment through the use of a DLL (cygwin1.dll) which acts as a Linux API layer providing substantial Linux API functionality. Here's the link to the documentation for its API Edit: Most of the Cygwin source code that I've looked at is written in C++ and makes system calls using MS Windows API to do provide the *nix emulation. The source is well written and very readable (even to to a non-C++ programmer such as myself). I think using Cygwin would be a good transition from programming on Windows to a GNU/Linux environment.

Windows Lua to executable
srlua is distributed as source only, so you have to compile it first (see this answer for suggestions on getting a free C compiler). BTW, Cygwin is not necessary at all. The aforementioned link will lead you to instructions to install TDM-GCC, a Windows port of GCC compiler that will create executable files which only depend on Windows default system libraries. Once you have a C compiler in place and you have compiled srlua, you will have two executable files glue.exe and srlua.exe. This latter is only a stub, used by srlua.exe to generate the final executable by joining it with your Lua script. Assuming your script is myscript.lua and you want to create an executable named myexe.exe you must invoke glue.exe from the command line as follows: glue.exe srlua.exe myscript.lua myexe.exe

How to run C++ executable in Windows PE?
First of all, since the question is tagged "c++" and you mention C++/CLI several times, I assume that "Visual Basic 2010" is a typo for "Visual Studio 2010". But either way, whether you've written the application in Visual Basic (VB.NET) or C++/CLI, the problem is exactly the same. My guess is the executable can't run without certain dependencies that aren't loaded at this environment, but I need it to work in a PE. That's exactly correct. You've written an application that targets the .NET Framework. Somewhat like Java applications requiring a JVM, .NET applications require that the .NET Framework be installed in order to run (or a compatible alternative implementation, like Mono). Unfortunately, Windows PE does not support the .NET Framework. Note that it is irrelevant whether you

What actually happens when Windows installs something? Why not run the executable standalone?
This depends on how you have designed and planned your deployment: Let us say you have planned to have all your application dependencies in the same folder, and you have no dependencies on external assemblies, then you can develop your app and all its dependencies and put them in same folder. Now you can distrbute same folder, assuming you do not want to check for any pre-condition for running your app, now your app does not really require any installer. Also make sure your app does not depend on any registry entries etc. However most apps can not be like that, they would like to make sure the system is right, it has right version of windows, right dependencies are pre installed, and there are certain locations only where the app needs to be installed and only there it can work. Or the ap

cannot write file after user is logon on windows
The task scheduler runs as a specific system user, not as the user that just logged on. This means your code doesn't have the permission to change the user's files. While you can specify the user which task scheduler should use, you can't say "current user". You have two options: Put the file into the Autostart folder where it will be executed by the login code as the user. Change the permissions of the file that you intend to write and give the scheduler user write permission.
