How do I set environment variables during the docker build process? You can use ENV for environment variables to use during the build and in containers With this Dockerfile: FROM ubuntu ARG BUILD_TIME=abc ENV RUN_TIME=123 RUN touch env txt RUN printenv > env txt You can override the build arg as you have done with docker build -t temp --build-arg BUILD_TIME=def Then you get what you expect:
MSBuild: set a specific preprocessor #define in the command line I needed to do this too - needed to be able to build two different versions of my app and wanted to be able to script the build using VCBUILD VCBUILD does have the override command line switch, but I am not sure it can be used to modify #define symbols that can then be tested using #if conditional compilation
Define a preprocessor macro through CMake - Stack Overflow This is good, but do prefer literally #define foo in your header files whenever possible That's the best way to make sure everything using your header is consistently setting that value, regardless of OS, build system, compiler, etc If you must, set target_compile_definitions as demonstrated here
CMake how to set the build directory to be different than source . . . In case anyone did what I did, which was start by putting all the build files in the source directory: cd src cmake cmake will put a bunch of build files and cache files (CMakeCache txt, CMakeFiles, cmake_install cmake, etc) in the src dir To change to an out of source build, I had to remove all of those files
How do I show the value of a #define at compile-time? Helper macros to print the value of a macro at compile-time #define VALUE_TO_STRING(x) #x #define VALUE(x) VALUE_TO_STRING(x) #define PRINT_MACRO_AT_COMPILE_TIME(var) #var "=`" VALUE(var) "`" To use them: #pragma message PRINT_MACRO_AT_COMPILE_TIME(MY_INT) A word of caution: if the macro is not defined, its name will just be printed out again!
build - What exactly is Building? - Stack Overflow Deployment of distribution packages For example, the build could automatically deploy publish a new version of a web application (assuming that the build is successful) "The build" can be done "by hand" or it can be automated, or some hybrid of the two A manual build is a build that requires build commands like compilers to be executed one
Visual Studio - Where to define custom path macros? In 2019 you can add custom macros to all of your projects by adding a Directory Build props xml file at the root of your solution They don't show up in the macros section, but if referenced as usual with $(MacroName) they are used in the build <Project> <PropertyGroup> <Deterministic>true< Deterministic> < PropertyGroup> < Project>
How to define build-args in docker-compose? - Stack Overflow This answer is very useful, it actually shows how docker-compose can be used with --build-arg on command-line, you can define your ARG in Dockerfile, docker-compose yml - the :args array defined and then finally override it on the command-line
How do I setup visual studio to register some #defines globally? What I mean is, in each of my source files I have to insert #define NOGDI to stop windows h from including GDI defines (since it's BITMAP define conflicts with mine) e g #define NOGDI #include <windows h> Unfortunately, I have to do this in every seperate source file which includes windows h, which I do not want to do
