This document provides useful background information to the uninitiated. Install it, but only select the following component: Update – I now realise that this archive also includes the whole GCC toolchain as well, but by then I’d already written the guide :)ĭownload the latest DirectX SDK.
Extract that archive into C:\mingw64_4.5.2_multilib so you have a subfolder in there named MSYS. I spent a long time trying to compile LAME with the official MSYS build and eventually gave up, chosing instead to use a working one made by a third party. There is no installer – it’s not as automated as the 32bit distribution of MinGW.
Extract the contents of this archive to the root of your C: drive (which at time of writing will create a folder named mingw64_4.5.2_multilib). On the MinGW-w64 downloads site browse to the Multilib Toolchains (Targetting Win32 and Win64) section, and download the latest megasoft78 binary build prefixed with mingw-w64-bin_x86_64-mingw. Most people will want a toolchain with the flexibility to create both 圆4 and x86 binaries, so that is what I shall describe in this guide. What is more, I had to try three different ones before I found one that could compile LAME without errors (though that could be LAME’s fault). What’s even more confusing, is that some builds of MinGW-w64 are targetted at 32bit, some 64bit, and some both. As a result you have to search around trying to find all the necessary configure commands for each package, and they’re not always identical. It’s not strictly necessary with all packages, but some will fail to build without these parameters.
The complication is that even when compiling natively you need to use configuration options as if you’re cross compiling (for host type x86_64-w64-mingw32). A perfect topic for PCLOADLETTER then!įor building FFmpeg we must use the build environment MinGW-w64 which is a separate version of MinGW. Once I had compiled FFmpeg for 32bit Windows, I discovered that it’s probably ten times more difficult to find information about doing the same with free tools on 64bit editions of Windows.
