[solved] Mex: Unresolved External when using .lib file

Edit: So apparently, the library I was trying to link was compiled in 32 bit, while matlab is a 64 bit version...

Recompiled the library in 64 bit and now it seems to work...

Hi,

So, I'm trying to compile a mex file which uses the Lis library (for linear solvers). When trying to compile it using this command:

    mex -v -g -LC:\tmp\lis-1.4.39\lis-1.4.39\lib -llis src\linear\LinearSolvers\lisSolve.cpp

I get the following errors:

    |lisSolve.obj : error LNK2019: unresolved external symbol lis_matrix_assemble referenced in function "int __cdecl lisSolve(double *,int *,int *,double *,double *,char *,int,int,int)" (?lisSolve@@YAHPEANPEAH100PEADHHH@Z)|

|lisSolve.obj : error LNK2019: unresolved external symbol lis_matrix_set_coo referenced in function "int __cdecl lisSolve(double *,int *,int *,double *,double *,char *,int,int,int)" (?lisSolve@@YAHPEANPEAH100PEADHHH@Z)| 

|lisSolve.obj : error LNK2019: unresolved external symbol lis_matrix_set_size referenced in function "int __cdecl lisSolve(double *,int *,int *,double *,double *,char *,int,int,int)" (?lisSolve@@YAHPEANPEAH100PEADHHH@Z)| 

|lisSolve.obj : error LNK2019: unresolved external symbol lis_matrix_create referenced in function "int __cdecl lisSolve(double *,int *,int *,double *,double *,char *,int,int,int)" (?lisSolve@@YAHPEANPEAH100PEADHHH@Z)|

lisSolve.mexw64 : fatal error LNK1120: 4 unresolved externals

These are all four functions that are in the lib file. So somehow it seems that the .lib file is not linked correctly...

When I look at the verbose output, it says: |link /out:"lisSolve.mexw64" /debug /PDB:"lisSolve.mexw64.pdb" /dll /export:mexFunction /LIBPATH:"C:\Program Files\MATLAB\R2012b\extern\lib\win64\microsoft" libmx.lib libmex.lib libmat.lib

/MACHINE:X64 kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib /nologo /manifest /incremental:NO

/implib:"C:\Users\($username)\AppData\Local\Temp\mex_o8yehq\templib.x" /MAP:"lisSolve.mexw64.map" @C:\Users\($username)\AppData\Local\Temp\mex_o8yehq\mex_tmp.rsp C:\tmp\lis-1.4.39\lis-1.4.39\lib\lis.lib |

So at the last line of this wall of text, it shows that the lis.lib file somehow is included in the link command.

Can somebody tell me what I am doing wrong? Because it seems that I fail to properly let the linker know where to find these function definitions...

Thank you in advance!!!
