BPCells package 安装问题

1. install BPCells package
remotes::install_github("bnprks/BPCells")    
#error: unable to locate libhdf5.

2. 通过查阅官网发现需要先安装hdf5:
“..., before installing BPCells, we must have the HDF5 library installed and accessible on the system.”

3. Two solutions: homebrew install hdf5 or conda install hdf5. For MacOS, installing hdf5 through homebrew seems to be most reliable: brew install hdf5.

4. So, we need to install homebrew first before installing hdf5. I ran the below code in the Mac terminal, not Rstudio console.
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
eval "$(homebrew/bin/brew shellenv)"
brew update --force --quiet
chmod -R go-w "$(brew --prefix)/share/zsh"

5. Then, I start to install hdf5 using brew command in the terminal, where the brew locates at /homebrew/bin/.
brew install hdf5

6. Sometimes, it will end with error:
#Error: Your Command Line Tools are too outdated.
#how to figure this out???
#The output of this run will give you below suggestion to figure it out. So, I run the below code in the Mac terminal with sudo access.
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

7. Create .R directory in your $home (/Users/jiajia) and touch a Makevars file in it. It looks like:
/Users/jiajia/.R/Makevars.

8. edit the Makevars file with below information:
{
CC=/Users/jiajia/homebrew/Cellar/llvm/17.0.4/bin/clang-17
CXX=/Users/jiajia/homebrew/Cellar/llvm/17.0.4/bin/clang++
CFLAGS=-I/Users/jiajia/homebrew/Cellar/hdf5/1.14.3/include
CXXFLAGS=-I/Users/jiajia/homebrew/Cellar/hdf5/1.14.3/include
LDFLAGS=-L/Users/jiajia/homebrew/Cellar/hdf5/1.14.3/lib
}
每个人保存的文件夹位置可能不同，只需要能找到对应的目录即可。

Finally, I successfully installed the BPCells package in the Rstuido.
