Hello everyone, I'm confused while installing the libsvm pack to matlab.
there're some .c file (such as svm-scale.c) and I try:
>> mex svm-scale.c
and got:
if true
Undefined symbols for architecture x86_64:
"_mexFunction", referenced from:
-exported_symbol[s_list] command line option
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
mex: link of ' "svm-scale.mexmaci64"' failed.
Error using mex (line 206) Unable to complete successfully.
end
Actually, I've read the relative articles, https://www.mathworks.com/matlabcentral/answers/103258 http://www.mathworks.com/matlabcentral/answers/103904
but it doesn't work. I've modified the 10.7 to 10.9, and I do have a gcc located in
/usr/bin/gcc
could anyone give some solutions? Thank you very much!
And here's my mexopts.sh file
if true
#
# mexopts.sh Shell script for configuring MEX-file creation script,
# mex. These options were tested with the specified compiler.
#
# usage: Do not call this file directly; it is sourced by the
# mex shell script. Modify only if you don't like the
# defaults after running mex. No spaces are allowed
# around the '=' in the variable assignment.
#
# Note: For the version of system compiler supported with this release,
# refer to the Supported and Compatible Compiler List at:

# SELECTION_TAGs occur in template option files and are used by MATLAB
# tools, such as mex and mbuild, to determine the purpose of the contents
# of an option file. These tags are only interpreted when preceded by '#'
# and followed by ':'.
