I'm trying to use boost in mexfunctions.
Given below is my code
main.cpp
#include <mex.h>
#include <boost/thread.hpp>
#include <boost/date_time.hpp>
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
mexPrintf("test boost");
}
I compile it using the below command
mex main.cpp -LC:\Boost\1.55.0\VC\10.0\x64\stage\lib -IC:\Boost\1.55.0\VC\10.0\x64
Then i get this linking error
LINK : fatal error LNK1104: cannot open file 'libboost_thread-vc100-mt-1_55.lib'
C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Link of 'main.mexw64' failed.
Then I compiled again using,
mex main.cpp -LC:\Boost\1.55.0\VC\10.0\x64\stage\lib -IC:\Boost\1.55.0\VC\10.0\x64 -llibboost_thread-vc100-mt-s-1_55
But still I get the same error. How can I solve this ?
EDIT :
I can use boost in a normal visual studio c++ project without any issue. The issue only comes when I put it in a mexfunction
I know this question is pretty old now, but I've had a similar issue with mex and I could solve it by specifying not only the library directory search path, but also the name of the compiled library object.
For that I used the following command:
mex main.cpp -I<path/to/lib> -L<path/to/lib/objects> -l<object_name>
The command line option -l is used to tell mex to link a specified object library. Mex will then try to find whatever is added to -l and will append .lib for windows and .LIBEXT for unix.
Here an example with real paths:
mex main.cpp -IC:\boost_1_54_0 -LC:\boost_1_54_0\release -lthread
And finally in your case I would suggest trying:
mex main.cpp -IC:\Boost\1.55.0\VC\10.0\x64 -LC:\Boost\1.55.0\VC\10.0\x64\stage\lib -lthread
EDIT:
I noticed that defining BOOST_ALL_NO_LIB also helps, because when I remove this define I get the error again. To define a symbol name you can use the command line option -D so just add -DBOOST_ALL_NO_LIB
