Problems with jpeglib

fellows, hi again

I'm having problems with the jpeglib. When I compile the program, the compiler shows these errors. What's the matter.Thanks.
My compiler is the Dev C++ 4.9.9.2:

Code:

---

In Project options, Parameters tab, Linker section, you should write:

Code:

---

-ljpeg

---

, or in makefile.win you should have

Code:

---

LIBS =  -L"C:/DEV-CPP/lib" -mwindows -ljpeg

---

And you should also place libjpeg.a in a place where the linker might find it, e.g. in C:\Dev-Cpp\lib.

Thanks for help oliv.... I'll test in my house.... where the problematic compiler resides....

Thanks again....

Oliv I've tried your tips, but they doesn't work. I don't know if I've installed the jpeglib.h correctly. Do you know any place that can I see the steps?
If you know, would you mind to help me in this?


Thanks again.....
