Re: problem with compiling different C files with a global structure

[Leon Opit <leon opit locsoft com>]

Hi Debmalya,

Do not use automatic initialisation in variables with the extern attribute.

Initialise a.data by assignment in main(). 
This is not the whole story but then your example code is not exactly what you tried to compile!

(calling cal() in main() ) but defining call in call.c never-the-less you get the idea)

Hello, 

Though this might not be the place for this type of query, this problem I'm giving here is a simplest scale version of a problem when I am trying to split up a large gtk source code of mine.

I'm trying to compile a program with 3 diff C files.

main.c

call.c

global.c

I want to declare a global structure variable and assign a value to it's content in main.c

then I  will call another function (declared at call.c ) to print the global variable.

I have a structure definition in global.c which I have declared as extern in the common header file head.h through another header file global.h

Program is not compiling.

Am I missing some points here?
