I'm creating a docker image as a build environment where I can mount a project and build it. For build I use cmake and conan. The dockerfile of this image:
FROM alpine:3.9
RUN ["apk", "add", "--no-cache", "gcc", "g++", "make", "cmake", "python3", "python3-dev", "linux-headers", "musl-dev"]
RUN ["pip3", "install", "--upgrade", "pip"]
RUN ["pip3", "install", "conan"]
WORKDIR /project
Files like
~/.conan/profiles/default
are created after I call
conan install ..
so that these files are created in the container and not in the image. The default behavior of conan is to set
compiler.libcxx=libstdc++
I'd like to run something like
RUN ["sed", "-i", "s/compiler.libcxx=libstdc++/compiler.libcxx=libstdc++11/", "~/.conan/profiles/default"]
to change the libcxx value but this file does not exist at this point. The only way I found to create the default profile by conan would be to install something.
Currently I'm running this container with
docker run --rm -v $(dirname $(realpath $0))/project:/project build-environment /bin/sh -c "\
rm -rf build && \
mkdir build && \
cd build && \
conan install -s compiler.libcxx=libstdc++11 .. --build missing && \
cmake .. && \
cmake --build . ; \
chown -R $(id -u):$(id -u) /project/build \
"
but I need to remove -s compiler.libcxx=libstdc++11 as it should be dependent on the image and not fixed by the build script.
Is there a way to initialize conan inside the image and edit the configuration without installing something? Currently I'm planning to write the whole configuration by myself but that seems a little too much as I want to use the default configuration and change only one line.
