I'm new to visual studio and visual micro.

I've been using arduino ide to do my development, and decided to try visual Studio/visual micro solution.

my sketch is compiling and running with arduino IDE just fine yet when using visual micro I get and error

"Sketch2.ino:In function 'void setup()
Sketch2.ino:279:22: error: 'displaymenu' was not declared in this scope
:displaymenu(menuPage)
Sketch2.ino:In function 'void loop()
Sketch2.ino:295:13: error: 'changeMenu' was not declared in this scope
:changeMenu()
Sketch2.ino:296:22: error: 'displaymenu' was not declared in this scope
:displaymenu(menuPage)
Error compiling project sources
"

To turn arround the problem I had to declare all function prior to setup() and loop() declaration by adding this code 

"int len(char* str);
byte checksum(char *str);
void changeMenu();
void d2i(float input, float factor, long &major, long &minor);
long min2dec(long minor);
float GPSDist(float uselat, float uselon, long int *homedist, long int *homeazim);
void displayReset();
void fixposition();
void logposition(float loglat, float loglong);
void displaymenu(byte menuPage);
"
the function definition code is still placed after setup() and loop() definition.

1- WHY ? 
2- is there an option to allow code syntax to respect arduino  IDE rules ?

thank you for any help you may give.

Thanks Visual Micro for your timely comment.

I am actually using IDE 1.6.9 , and I do have a user defined type (a struct).

Just by pure change I did insert my definition after the user defined type and it worked (I was not aware of such requirement).

thank you for your confirmation and i'll be waiting for that new feature .

Is there a version of visual micro to run on a MAC on top of some MAC(ish) IDE, like Xcode, or atom, or QT or ????
