Makefile: преобразование C-кода в мекс-код (ошибка компоновки)
у меня естьC-code which works fine используя makefile. Теперь я пытаюсьconvert it to mex файл, чтобы я мог запустить его из Matlab. Вот и яusing makefile approach, Но makefile для mex выдает ошибку.
Здесьtsnnls lib что я хочу скомпилировать вместе с моим mex файлом.
Организация C-проекта:
tsnnls_test_DKU.c
Include_4_TSNNLS.c
Include_4_TSNNLS.h
"Include_4_TSNNLS.*"файлы имеют функциюTestingLibraries() которые называют библиотеки третьей части; пока я пытался удержатьtsnnls_test_DKU.cочень просто, как:
Оригинальный код: tsnnls_test_DKU.c
int TestingLibraries() ;
int main( int argc, char* argv[] )
{
int k = TestingLibraries() ;
return(1);
}
Теперь код был изменен:
Измененный код: 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() ;
}
Оригинальный файл make (который работает

Изменен Makefile, который не запускается Заметьте, я вернул ссылку на оригинал с помощью компилятора gcc; Тем не менее, я хотел бы использовать здесь Mex.
Я изменил некоторые строки, основываясь на моем понимании, и использовал тег "# mex".
Кроме того, Include_4_TSNNLS.o успешно создается. Кроме того, предыдущая проблема с «include» была решена путем жесткого подключения всех путей.
