TDM-GCC

TDM-GCC is a Windows-friendly version of the GCC compiler that lets you write programs with no DLL dependence. To download and use TDM-GCC, please visit [https://jmeubank.github.io/tdm-gcc/].

tdminstall

This repository contains the code for the TDM-GCC installer system, which is based on NSIS and several plugin DLLs.

TDMInstall provides a setup wizard capable of automatically downloading, installing, upgrading, and removing versioned components of a working MinGW or MinGW-w64 GCC installation. It does this separately from MSYS, mingw-get, or MSYS2's pacman, and is not designed to include those components.

TDMInstall features:

• Component descriptors and installation manifests use XML
• Discriminatory uninstallation: only remove files installed by the setup program
• Support online-only or online/offline installers with inner components
• Download latest descriptor file to determine available components
• Update to newer component versions by automatically removing the old version, then installing the new version
• Let users select from multiple download mirrors (becoming obsolete)
• Unpack the common archive types created by upstream distributors: zip, 7z, tar.gz, tar.bz2, tar.lzma, tar.xz (as supported by XARC)
• Download component archives with resume capability (uses the Inetc plugin for NSIS)
• Track multiple installations
• No Windows registry entries created

Prerequisites

The mingw-build.cmd script is capable of downloading and unpacking most of the required external libraries and binaries needed to create a TDM-GCC installer. All that is needed to initiate the build process on a relatively modern Windows system are:

• A working MinGW or MingW-w64 GCC installation (GCC, GNU binutils, and the appropriate runtime and Windows API libraries), such as a prior TDM-GCC installation
• A version of GNU make (mingw32-make by default, as included with TDM-GCC)
• 7z.exe, which is included with the 7-Zip Windows installers

The tdminstall.dll plugin is currently built and tested under TDM-GCC version 4.7.1 for MinGW. Later versions of GCC have added significant code bloat when using the C++ standard library, but version 4.7.1 creates a DLL just a few hundred kilobytes in size.

If you want to use versions of the other TDMInstall dependencies that are already installed, the mingw-build.cmd script doesn't easily allow for it just yet. The dependencies it installs are:

• CMake
• TinyXML-2
• NSIS
• UPX
• XARC
• Lua
• Minilibs

The mingw-build.cmd script will attempt to download and unpack them into an "extlibs" subdirectory of the directory that you build in.

Building

Create an empty build directory. It can be any directory. Don't make a liar out of me.

From a command prompt in that directory, run the mingw-build.cmd script. It will create and populate the 'extlibs' subdirectory with upstream requirements, run cmake.exe to generate build system components and a Makefile, and then run mingw32-make.exe. This will create the installer executables in the current directory.
