Dear @km-b214
what ROOT do you use?
Do you use local build?
Has it been built with MathMore?

[km-b214]

Hello,

It used to be good. However, after I reinstalled ROOT by building from source, there was an error after I ran a script with this library. I've tried to reinstall this ostap library again, then there is error. I thought that the problem is from cmake but it is not.

This is how installed ROOT (from root.cern/install/:

The latest stable branch gets updated automatically on each release.

You may update your local copy by issuing a git pull command from within root_src/.

$ git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git root_src
$ mkdir root_build root_install && cd root_build
$ cmake -DCMAKE_INSTALL_PREFIX=../root_install ../root_src # && check cmake configuration output for warnings or errors
$ cmake --build . -- install -j4 # if you have 4 cores available for compilation
$ source ../root_install/bin/thisroot.sh # or thisroot.{fish,csh}

Dear @km-b214

Here there is a recipe to build ROOT with MathMore -
in turn, it requires GSL.

[VanyaBelyaev]

I suspect that MathMore is not build due to missing GSL

Dear @km-b214
Have you solved the issue?

[km-b214]

Hello. The problem hasn't been solved. I believe that mathmore library is not properly installed. I can't find libmathmore.so in the library folder although gsl library is successfully installed. I am still trying to follow the link but it is not clear to me. I can comeback to you if there is still an error after the library has been installed successfully.
