build error with -o proxyfmu=True : Could NOT find Boost (missing: filesystem) (found suitable version"1.71.0", minimum required is "1.71")

[xmirabel]

Prerequisite: conan 1.60 installed (conan 2 does not work with libcosim)

when running:
conan install .. --build=missing -o proxyfmu=True

the following error occurs:
CMake Error at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

A (not desirable) workaround is to install boost using:
sudo apt-get install libboost-all-dev

But then a compilation error occurs in src/proxyfmu/fmi/fmicontext.hpp

It is needed to add the following headers:
#include <cstdlib>
#include <cstdio>
#include <array>

[markaren]

Not the best solution, but if you use gcc9, you should get precompiled binaries with conan, thus omitting the issue you are facing.

[xmirabel]

I had the installation of the older compiler by the following sequence of commands:

sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
sudo apt-get install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 90 --slave /usr/bin/g++ g++ /usr/bin/g++-9
sudo update-alternatives --config gcc then select gcc-9

Then check with:
g++ -v
and
gcc -v
that answer:
gcc version 9.5.0 (Ubuntu 9.5.0-1ubuntu1~22.04)

Then change the conan configuration of the compiler to 9 in ~/.conan/profiles/default:
compiler.version=9

Then redo the compilation procedure:
rm -r build/ ; mkdir build ; cd build
conan install .. --build=missing
cmake .. -DLIBCOSIM_USING_CONAN=TRUE -DCMAKE_BUILD_TYPE=Release
cmake --build .

check the conan boost version installed:
$HOME/.conan/data/boost/1.71.0

but the final result is an error:

[xmirabel]

A workaround is to disable test generation:

cmake .. -DLIBCOSIM_USING_CONAN=TRUE -DCMAKE_BUILD_TYPE=Release -DLIBCOSIM_BUILD_TESTS=false
cmake --build .

[xmirabel]

A local installation can be done:
cmake .. -DLIBCOSIM_USING_CONAN=TRUE -DCMAKE_BUILD_TYPE=Release -DLIBCOSIM_BUILD_TESTS=false -DCMAKE_INSTALL_PREFIX=$HOME/osp/install/linux-release/
cmake --build . --target install
