Error on make in MacOS
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> ^~~~~~~~~ 1 error generated. 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
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.

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