First time building a library, compile issues

i working graphical lcd has large number of serial commands different functions.
in attempt clean workflow , simplify code have attempted build library, unfortunatly without success. have followed stock tutorial , compared against other libraries have downloaded yet cannot mine function.

as secondary question, have alternative arduino ide allow me edit these c based files highlighting, compiling , downloading arduino programs.

program file:

code: [select]

#include <lcd.h>

lcd lcdlib()

void setup(){
 
}

void loop(){
 
}



compiler report:
in file included sketch_apr09a.cpp:1:
c:\users\apothus\documents\arduino\libraries\lcd/lcd.h:15: error: expected unqualified-id before ')' token
sketch_apr09a:0: error: new types may not defined in return type
sketch_apr09a.cpp:4: note: (perhaps semicolon missing after definition of '<anonymous class>')
sketch_apr09a:0: error: 2 or more data types in declaration of 'setup'

header file lcd.h:

any advice on code appreciated. has been long time since have written librarys or header files. unclear on case requirements arduino, know c can little sensitive case @ times.
