[Create mexfunction from C code] The order of several c files

2 views (last 30 days)
I have a c source code that consists of several .c files. How can I know the orders of these files when I build the mex function?
for example:
mex mainFun.c X.c Y.c Z.c
This is the source code:
I have got this error "Error using mex D:\TestMexFunction\unix_timer.c:22:26: fatal error: sys/resource.h: No such file or directory #include <sys/resource.h> ^
compilation terminated." when I run:
mex mainFun.c ants.c parse.c TSP.c dos_timer.c InOut.c ls.c unix_timer.c utilities.c
mainFun.c includes the mexFunction()
acotsp.c includes the main() function
Is it because of the order of c files or another reason?

The order you compile your source code files should not matter (other than the fact that the mex function name will be based on the first file listed unless you override that). The error seems to be that the compiler can't find the resource.h file.

Yes it is a compiler problem, I have tried to run the C code alone with MinGW compiler and I got same problem with resource.h. MinGW does not have <sys/resource.h>
when I change to cygwin64 it works. However, Matlab does not support cygwin compiler. what I should do in this case?

I have solved the problem by modifying the C code (by removing resource.h)
