| # ult notes: | |||
| # ============== | |||
| # This makefile provides support for unix-like local builds and | |||
| # docker based builds for gcc and clang. | |||
| # ** msvc is not currently supported. | |||
| # | |||
| # Use cases: | |||
| # 1) build localy using **local rules** in terminal. | |||
| # example: | |||
| # make -j4 MK_ARG="-std=c++14 -fconcepts" build-gcc | |||
| # | |||
| # 2) build localy using **docker based rules** via terminal or script | |||
| # in order to compile for all compilers/versions/dialects. | |||
| # example in bash: | |||
| # #!/bin/bash | |||
| # for im in gcc:8 gcc:9 gcc:10; do | |||
| # for dial in -std=c++14 -std=c++17; do | |||
| # make IMAGE="$im" MK_ARG="$dial" dock-gcc | |||
| # done | |||
| # done | |||
| # | |||
| # 3) build inside a docker instance using **local rules** in order to | |||
| # build and test using a CD/CI system. | |||
| # example in a yml file: | |||
| # image: gcc:8 | |||
| # build: | |||
| # stage: build | |||
| # - make MK_ARG="-std=c++14" build-gcc | |||
| # - make MK_ARG="-std=c++14 -fconcepts" build-gcc | |||
| # - make MK_ARG="-std=c++17" build-gcc | |||
| # - make MK_ARG="-std=c++17 -fconcepts" build-gcc | |||
| # - make MK_ARG="-std=c++2a" build-gcc | |||
| # ... etc | |||
| # test: | |||
| # stage: test | |||
| # - bin/utlTest | |||
| # ... etc | |||

| # ============== Docker settings ============== | |||
| # We need: | |||
| # 1) Bind the entire project directory(the dir that icludes all the code) as volume. | |||
| # 2) In docker instance change to working directory(where the makefile is). | |||
| # For utl we use the directories `${PWD%/*}` and `test`. | |||
