compilation

I'm trying to build the ffmpeg binaries for android on 3 chipsets. The output file size is too large to include in the project around 15mb. https://github.com/falnatsheh/ffmpeg-android is the github project repo the .sh build script for ffmpeg is like this #!/bin/bash . abi_settings.sh $1 $2 $3 pushd ffmpeg case $1 in armeabi-v7a | armeabi-v7a-neon) CPU='cortex-a8' ;; x86) CPU='i686' ;; esac make clean ./configure \ --target-os="$TARGET_OS" \ --cross-prefix="$CROSS_PREFIX" \ --arch="$NDK_ABI" \ --cpu="$CPU" \ --enable-runtime-cpudetect \ --sysroot="$NDK_SYSROOT" \ --enable-pic \ --enable

This question was migrated from Software Engineering Stack Exchange because it can be answered on Stack Overflow. Migrated 4 years ago . What exactly is the difference between using either ' var ' or ' let ' in Typescript? I know that 'let' allows the variable to be defined further into a scope without it being used outside of said scope. That is obviously a nice advantage for iterators in for loops. I know this is an ES6 definition, so compiling to ES6 should look nearly identical in terms of 'var' and 'let'. But, when it compiles down into ES5 javascript which doesn't support 'let', what

Does anyone know how to run/compile Ruby programs on Windows 7? For example you can compile Java in Eclipse, but I can't seem to find one for Ruby. http://rubyinstaller.org/ - "The easy way to install Ruby on Windows". Will give you the language and execution environment - everything you should need to get started. Ruby isn't compiled, but rather interpreted. You need to install Ruby using the above link given by @ilollar. Then, if you have the source code of a program in the file some_ruby.rb , you will execute this in cmd: ruby some_options.rb This is the general form of a ruby command: ruby

Suppose I generate a C program during execution time: source = "int add_x_y(int x, int y){ return x + y; }"; source_size = 42; I want the following function: void* compile(char* source, int source_size); Such that: int (*f)(int,int) = compile(source, source_size); printf("%d\n",f(2,3)); Outputs: 5 And compile can't depend on external tools (compilers), as I'd like to use it in emscripten (which converts a C program to a .js file). Is that possible? Someone else can probably fill in some of the specifics better than I, but if you don't mind calling out to GCC or linking to it, it should be
