Hi, there, Assume I have a mexmain.c which contains mexFunction(), in mexFunction(), I call another function e.g. test() defined in another c file e.g. test.c. The test.c is very simple #include <math.h> int test() { return sqrt(4); } If I generate test.obj by 'lcc test.c', (I use lcc-win32 as my c compiler) then command 'mex mexmain.c test.obj' will give following err: test.obj .text: undefined reference to '_sqrtid' However if the test.obj is generated by 'mex -c test.c', and then 'mex mexmain.c test.obj', it works. I am confused about the difference between these 2 ways. Anybody can explain it? Thanks in advance! -- Bing |
