Dear all ,
I have one shared library in "/usr/lib/ast/mod/quad.so"
where the functions "X1" and "X2" are defined.
In header file "quad.h" it is declared.
I have created a "test.c" where X1 and X2 are called
I have used the following commads for compiling and linking
#gcc -c test.c
#gcc -o test.o -L. -Wl,-rpath,/usr/lib/ast/mod/quad.so
i am getting the error:
undefined reference to X1
undefined refernece yo X2
what all things i have to do to make a proper linking
According to the manual, rpath specifies a directory, not a file. Also, you probably don't want test.o to be the output, but the input. I don't remember right now whether the linker needs any special hints about .so files; I would start with
(since you can put however many input files on a line as you want), and then maybe add a -R linker option if necessary.Code:gcc -o test test.o /usr/lib/ast/mod/quad.so
thank u for ur reply.. i tried that earlier but so may undefined reference errors are coming then .that is why i used -L. option .when it is giving only the function which i called from main program is showing undefined reference errors
Undefined references to what? Do you have other libraries you need to link in, or something?
