It seems that your compiler is defaulting to gcc. Try clang:

CC=clang CXX=clang++ pip install git+https://github.com/teemupitkanen/mrpt/

thanks for reply! the command still not worked..

Do you have Xcode Command Line Tools installed? Try

xcode-select --install

[tony-tian]

ensure the installation..still unable to install...but very thanks for help! still hope for further communication

[ejaasaari]

Can you try what's suggested here, mainly the brew install python part? If that doesn't work, try without using anaconda.

[tony-tian]

hard to work without anaconda...maybe I need to wait for further updates in order to get it working..thanks for the help and reply, and hope for any advice if available.

[tony-tian]

sir...now the question becomes:cpp/Mrpt.h:10:10: fatal error: 'random' file not found.. after google it, I found bit of the question...seemed seldom happened.. do need your help,plz

[ejaasaari]

Your compiler apparently doesn't have C++11 support. What version of clang are you using?

[tony-tian]

clang version 4.0.1 (tags/RELEASE_401/final)
Target: x86_64-apple-darwin17.5.0
Thread model: posix
InstalledDir: /Users/tianyizhuang/anaconda3/bin

I wonder the C++11 support have something wrong because only random package could not be found...

I saw many similar errors as above, however I was able install successfully on Mac OS Catalina with Anaconda 3.7 using the following commands:

brew update brew install llvm

CC=/usr/local/opt/llvm/bin/clang CXX=/usr/local/opt/llvm/bin/clang++ CPATH=/usr/local/opt/llvm/include/c++/v1 pip install git+https://github.com/teemupitkanen/mrpt/

Thanks for taking the time to open source this great package!
