Conan for OpenFOAM

Simplifies the linking process of external libraries to OpenFOAM

New libraries can be download easily from the conancenter and linked to OpenFOAM

Prerequisite

Assuming we already have anaconda and OpenFOAM is sourced installed:

    conda create -n conan python=3.9 # we dont want break our install
    conda activate conan
    pip install conan # conan is required

Usage

cat option.template:

CONAN_INCS := \
    {{{CONAN_INCS_INCS}}}

CONAN_LIBS := \
    {{{CONAN_INCS_LIBS}}}


EXE_INC = \
    -I../../../src/lnInclude \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude \
    $(CONAN_INCS)

EXE_LIBS = \
    -lfiniteVolume \
    -lmeshTools \
    $(CONAN_LIBS)

add CONAN_INCS and CONAN_LIBS to your options file and place it in the Make folder. The generator will replace

{{{CONAN_INCS_INCS}}}

and

{{{CONAN_INCS_LIBS}}}

with the cached libraries in conan

Install OpenFOAM generator

    cd OpenFOAMGen
    conan export . myuser/OpenFOAMGen

The generator is now installed

Compile OpenFOAM with Boost regexp and lohmann json

    cd test-conan
    conan install . -s compiler=gcc -s compiler.libcxx=libstdc++11 --build

boost and the json library are now downloaded and compiled. Conan needs to know the compiler version and the c++ standard to download the correct version.

Note: this will take a while.

    wmake # compiles est-boostReg-CreditCardNumber and links it with conan-libs
    test-boostReg-CreditCardNumber 1000-1000-1000-1000 

And you should see:

dumping json{
    "answer": {
        "everything": 42
    },
    "happy": true,
    "list": [
        1,
        0,
        2
    ],
    "name": "Niels",
    "nothing": null,
    "object": {
        "currency": "USD",
        "value": 42.99
    },
    "pi": 3.141
}
