I'm trying to compile a piece of C code that uses the Libredwg libraries.

I can call the library functions by including 'dwg.h':

Code: Select all

 #include "dwg.h"

If I reference a funtion

Code: Select all

error = dwg_read_file (filename_in, &dwg);

I get no errors from KDevelop.

However, when I compile the code with gcc, I get ther following errors:

Code: Select all

dave@Tuffy:/opt/libredwg/examples$ gcc -o ldwg load_dwg.c
/usr/bin/ld: /tmp/cc3rVjKS.o: in function `load_dwg':
load_dwg.c:(.text+0x586): undefined reference to `dwg_read_file'
/usr/bin/ld: load_dwg.c:(.text+0x75f): undefined reference to `dwg_free'
collect2: error: ld returned 1 exit status


The Gnu Compiler clearly cannot refference the function, although it would appear that KDevelop does.

Is there a way to apply the way that KDevelop is configured to the Gnu compiler?

Or, alternatively, is it possible to get KDevelop to compile the code?
