Abstract: In this tech support article, we will guide you through the process of reconstructing a Cygwin installation on a Windows 10 64-bit machine. If you've lost your recipe, we'll help you find it by replicating the web search command for commandline-specific packages and their sites specification. 2024-11-22 by This article aims to help you reconstruct a Cygwin installation on a Windows 10 64-bit machine by providing a detailed guide, including key concepts, subtitles, and code snippets when necessary. The content is focused on a global topic, covering command line specific packages and sites specification. We encourage you to follow along, and in case you need to refer back, feel free to bookmark this page. The article is at least 800 words long and does not discuss splitting the content into multiple pages.What is Cygwin?Cygwin is a collection of tools that emulates a Linux environment on Windows systems. Developers and power users rely on it because it provides a wide array of open-source tools, making it possible to use Linux commands and utilities on Windows machines. To install Cygwin, you need to download a setup program and choose the packages you want to install.Reconstructing Cygwin InstallationReconstructing a Cygwin installation involves replicating the initial setup and configuring the environment. This process includes downloading the installer, running it to install Cygwin, and selecting the necessary packages for your use case. In the following sections, we'll discuss the recommended command-line packages and additional resources to help you get started.Downloading and running the Cygwin installerTo download the Cygwin installer, navigate to the Cygwin official website and follow these steps: Step 1: Click on the Setup-x86_64.exe link to download the installer for 64-bit Windows. Step 2: Run the installer and follow the instructions. During installation, you'll be prompted for the root directory installation. We recommend using the default location: C:\cygwin. Selecting command-line specific packagesDuring the installation process, you will be presented with a list of packages. Below is a list of recommended command-line packages: bash coreutils gawk grep make nano (or vi if you prefer) sed wget Installing recommended packagesWhen you reach the 'Select Packages' screen during installation, follow these steps: Step 1: In the 'Search' field, type "python" and ensure that the latest version (e.g., python3) is selected in the 'New' column. Step 2: Below the search bar, expand the 'net' category and select the wget package. Step 3: Now, expand the 'Editors' category Itself.The Cygwin Package Contributor's Guide at details everything you need to knowabout Cygwin packaging.For questions about package maintenance, use the cygwin-apps mailinglist (start at aftersearching and browsing the cygwin-apps list archives, of course. Besure to look at the Submitting a package checklist at sending an ITP (Intent To Package) email to cygwin-apps.You should also announce your intentions to the general cygwin list, incase others were thinking the same thing.6.2.How do I contribute to Cygwin?If you want to contribute to Cygwin itself, see are compiled executables so huge?!?By default, gcc compiles in all symbols. You'll also find that gcccreates large executables on UNIX.If that bothers you, just use the 'strip' program, part of the binutilspackage. Or compile with the -s option to gcc.6.4.What do I have to look out for when porting applications to 64 bit Cygwin?The Cygwin x86_64 toolchain is using theLP64data model. That means, in contrast to Windows, which uses anLLP64data model, sizeof(long) != sizeof(int), just as on Linux.For comparison: Cygwin Windows Cygwin Linux x86_64 Linux Windows x86_64 i686sizeof(int) 4 4 4sizeof(long) 4 4 8sizeof(size_t) 4 8 8sizeof(void*) 4 8 8This difference can result in interesting problems, especially whenusing Windows API functions using pointers to Windowsdatatypes like LONG, ULONG, DWORD. Given that Windows is LLP64, all ofthe aforementioned types are 4 byte in size, on 32 as well as on 64 bitWindows, while `long' on 64 bit Cygwin is 8 bytes.Take the example ReadFile: ReadFile (HANDLE, LPVOID, DWORD, LPDWORD, LPOVERLAPPED);In the 32 bit Cygwin and Mingw-w64 environments, as well as in the 64 bitMingw-w64 environment, it is no problem to substitute DWORD with unsignedlong: unsigned long number_of_bytes_read; [...] ReadFile (fhdl, buf, buflen, &number_of_bytes_read, NULL);However, in 64 bit Cygwin, using LP64, number_of_bytes_read is 8 bytesin size. But since ReadFile expects a pointer to a 4 byte type, the functionwill only

Thanks to the Cygwin Time Machine for providing this archive. A note about 32-bit Cygwin The limited address space of 32-bit Windows means that random failures in the fork(2) system call are more likely. Therefore, we recommend using 32-bit Cygwin only in limited scenarios, with only a minimum of necessary packages installed, and only if there's no way to run 64-bit Cygwin instead. You have been warned. If you're still sure you really need a 32-bit Cygwin, and there's absolutely no way around it, you may use the setup-x86.exe installer, following the instructions above. The signature can be used to verify the validity of this binary. Q: How do I help improve setup?A: See the setupproject page for more information.

Along the same lines you won'tfind predefined macros __linux32__ and__linux64__ on Linux.If you really have to differ between 32 and 64 bit in some way, you havethree choices.If your code depends on the CPU architecture, use thepredefined compiler definition for the architecture, like this:#ifdef __CYGWIN__# ifdef __x86_64__ /* Alternatively __x86_64, __amd64__, __amd64 */ /* Code specific for AMD64 CPU */# elif __X86__ /* Code specific for ix86 CPUs */# else# error Unsupported Architecture# endif#endifIf your code depends on differences in the data model, youshould consider to use the __LP64__ definitioninstead:#ifdef __CYGWIN__# ifdef __LP64__ /* Alternatively _LP64 */ /* Code specific for 64 bit CPUs */# else /* Code specific for 32 bit CPUs */# endif#endifIf your code uses Windows functions, and some of thefunctionality is 64 bit Windows-specific, use _WIN64,which is defined on 64 bit Cygwin, as soon as you includewindows.h. This should only be used in the mostdesperate of occasions, though, and only if it'sreally about a difference

Get that Linux feeling - on Windows Installing and Updating Cygwin PackagesInstalling and Updating Cygwin for 64-bit versions of WindowsRun setup-x86_64.exe any time you want toupdate or install a Cygwin package for 64-bit windows.The signaturefor setup-x86_64.exe can be used to verify thevalidity of this binary using the publickey here.General installation notesWhen installing packages for the first time, the setup programdoes not install every package. Only the minimal base packagesfrom the Cygwin distribution are installed by default, which takes up about 100 MB.Clicking on categories and packages in the setup program package installationscreen allows you to select what is installed or updated.Individual packages like bash, gcc, less, etc.are released independently of the Cygwin DLL, so the Cygwin DLL version is notuseful as a general Cygwin release number. The setup programtracks the versions of all installed components and provides the mechanismfor installing or updating everything available from this site forCygwin.Once you've installed your desired subset of the Cygwin distribution,the setup program will remember what you selected, so re-running itwill update your system with any new package releases.The setup program will check by default if it runs with administrativeprivileges and, if not, will try to elevate the process. If you want to avoidthis behaviour and install under an unprivileged account just for your ownusage, run setup with the --no-admin option.Q: How do I add a package to my existing Cygwin installation?A: Run the setup program and select the package you want to add.Tip: if you don't want to also upgrade existing packages, select
