alpine-cpp

Minimal C++ development environment including gcc, CMake, cppcheck and conan, using Alpine Linux. This repo provides two docker images

alpine-cpp-x64:

GCC Target: x86_64-alpine-linux-musl
getconf LONG_BIT: 64

alpine-cpp-x86:

GCC Target: i586-alpine-linux-musl
getconf LONG_BIT: 32

Caveats

The working directory is set to /project and this is a folder that should be mounted from your host system to the docker image.

The image exposes as entrypoint the command bash -c, which allows you to give a sequence of commands, all included in quotation symbols ("") and let bash execute them. Alternatively, you can override the entrypoint by passing --entrypoint whatever_you_want as argument to docker command.

In the case where you are running x86 images on a x64 host, uname will return the host's kernel. Therefore tools that check the running kernel like conan and cmake might produce wrong output. For conan the 32bit image exports CONAN_ENV_ARCH=x86 ; however for cmake or gcc you must configure them properly to properly compile x86 binaries.

Usage Examples

conan based projects

docker run --rm -it -v $(pwd):/project -e CONAN_USER_HOME=/project pykler/alpine-cpp-x86:latest 'conan create ./ name/version@user/channel'

CMake based projects

docker run --rm -it -v $(pwd):/project pykler/alpine-cpp-x86:latest "mkdir -p build && cd build && cmake .. && make"

Makefile based projects

docker run --rm -it -v $(pwd):/project pykler/alpine-cpp-x86:latest "make"

g++ based projects

docker run --rm -it -v $(pwd):/project pykler/alpine-cpp-x86:latest "g++ yourfile.cpp youroutput.o"

Shell Access

docker run --rm -it --entrypoint bash -v $(pwd):/project pykler/alpine-cpp-x86:latest
