Hi,

I want to convert *.txt file to *.mat. So I am using matcreat.cpp. I included and mapped required header files in project. Then i starts getting error: g++ -o New_1.exe "src\\MatCreate.o" "src\\Main.o" "src\\INIReader.o" "src\\DataProcessing.o" src\MatCreate.o: In function `ZN9MatCreate13createMatFileEv': C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:37: undefined reference to `matOpen' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:44: undefined reference to `mxCreateDoubleMatrix_730' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:51: undefined reference to `mxCreateDoubleMatrix_730' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:57: undefined reference to `mxGetPr' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:60: undefined reference to `mxCreateString' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:66: undefined reference to `matPutVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:72: undefined reference to `matPutVariableAsGlobal' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:78: undefined reference to `matPutVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:89: undefined reference to `mxGetPr' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:90: undefined reference to `matPutVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:97: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:98: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:99: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:101: undefined reference to `matClose' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:109: undefined reference to `matOpen' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:118: undefined reference to `matGetVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:123: undefined reference to `mxGetNumberOfDimensions_730' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:128: undefined reference to `matGetVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:133: undefined reference to `mxIsFromGlobalWS' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:138: undefined reference to `matGetVariable' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:144: undefined reference to `mxGetString_730' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:155: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:156: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:157: undefined reference to `mxDestroyArray' C:\Users\pr896\Downloads\New_1\Debug/../src/MatCreate.cpp:159: undefined reference to `matClose' collect2.exe: error: ld returned 1 exit status

So I added libmx.lib, libmat.lib, libeng.lib, libmex.lib libraries in Project properties -> C/C++ Build -> MinGW C++ Linker -> Libraries also added path at library search path. Library search path is MATLAB->extern->lib->win32-> microsoft. I tried with win64 also. But getting same error.

The errors is: g++ "-LC:\\Software\\Mathworks\\32_bit_Matlab_All_Products_2010A_PSP_41\\extern\\lib\\win32\\microsoft" -o New_1.exe "src\\MatCreate.o" "src\\Main.o" "src\\INIReader.o" "src\\DataProcessing.o" -llibmx.lib -llibmat.lib -llibeng.lib -llibmex.lib c:/cpg_controls/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot find -llibmx.lib c:/cpg_controls/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot find -llibmat.lib c:/cpg_controls/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot find -llibeng.lib c:/cpg_controls/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot find -llibmex.lib collect2.exe: error: ld returned 1 exit status

My Windows 8.1 is 64 bit, MinGW is 32 bit and MATLAB 2010b 32 bit.

I am not getting whats wrong with this.
