Makefile: Convertir código C a código mex (error de enlace)
tengo unC-code which works fine usando makefile. Ahora estoy tratando deconvert it to mex archivo para que pueda ejecutarlo desde Matlab. Aquí también estoyusing makefile approach. Pero, makefile para mex me da un error.
Aquí está eltsnnls lib que quiero compilar junto con mi archivo mex.
Organización del proyecto C:
tsnnls_test_DKU.c
Include_4_TSNNLS.c
Include_4_TSNNLS.h
"Include_4_TSNNLS.*"los archivos tienen funciónTestingLibraries() que llaman bibliotecas de la tercera parte; mientras trataba de mantener "tsnnls_test_DKU.c"muy simple como:
Código original: tsnnls_test_DKU.c
int TestingLibraries() ;
int main( int argc, char* argv[] )
{
int k = TestingLibraries() ;
return(1);
}
Ahora, el código fue cambiado:
Código modificado: tsnnls_test_DKU.c:
#include "mex.h"
#include <math.h>
int TestingLibraries() ;
void mexFunction (int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) {
int k = TestingLibraries() ;
}

Se modificó el Makefile que no se ejecuta Tenga en cuenta que he revertido la parte de enlace al original con el compilador gcc; sin embargo, me gustaría usar mex aquí.
He cambiado algunas líneas en función de mi comprensión y he usado la etiqueta "# mex".
Además, Include_4_TSNNLS.o se está creando correctamente. Además, el problema anterior con "incluir" se ha solucionado cableando todos los caminos.
