Error on make in MacOS

[skysenscyu]

I am one of the mac user. However, when I typed make, this error occurred

clang: warning: no such sysroot directory: '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk' [-Wmissing-sysroot]
libsvmread.c:1:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
^~~~~~~~~

warning: mkoctfile: building exited with failure status
Error: /opt/local/share/octave/6.2.0/m/miscellaneous/mex.m failed (line 54)
mex: building exited with failure status
=> Please check README for detailed instructions.

does anyone know the reason why? I installed the linear file onto the readable directory, but this error occurred. I don't know what is the problem. THanks

THis was done under the Octave program

it seems you don't have C/C++ compiler installed. Please see the following libsvm faq: Q: I tried to install matlab interface on mac, but failed. What should I do? We assume that in a matlab command window you change directory to libsvm/matlab and type

> make

We discuss the following situations. An error message like "libsvmread.c:1:19: fatal error: stdio.h: No such file or directory" appears. Reason: "make" looks for a C++ compiler, but no compiler is found. To get one, you can Install XCode offered by Apple Inc. Install XCode Command Line Tools. On OS X with Xcode 4.2+, I got an error message like "llvm-gcc-4.2: command not found." Reason: Since Apple Inc. only ships llsvm-gcc instead of gcc-4.2, llvm-gcc-4.2 cannot be found. If you are using Xcode 4.2-4.6, a related solution is offered at http://www.mathworks.com/matlabcentral/answers/94092. On the other hand, for Xcode 5 (including Xcode 4.2-4.6), in a Matlab command window, enter cd (matlabroot) cd bin Backup your mexopts.sh first edit mexopts.sh Scroll down to "maci64" section. Change CC='llvm-gcc-4.2' CXX='llvm-g++-4.2' to CC='llvm-gcc' CXX='llvm-g++' Please also ensure that SDKROOT corresponds to the SDK version you are using. Other errors: you may check http://www.mathworks.com/matlabcentral/answers/94092.

I had Xcode before I installed this program. The version of Xcode was 12.4. And the problem still occurs. Is there some problem with my Xcode?

[cjlin1]

could you generate liblinear binary files in the main directory instead of the matlab interface?
