error C2099: initializer is not a constant

(Paul) #1

Hello all,

I’m working on the ET Dutch project now and instead of replacing all text everywhere i wanted to make a single file. But when i have this:
language.c


const char* Test1 = "CombatErvaring";

and use it here:
bg_misc.c


const char* skillNames[SK_NUM_SKILLS] = {
	Test1,
	"Engineering",
	"First Aid",
	"Signals",
	"Light Weapons",
	"Heavy Weapons",
	"Covert Ops"
};

I get the message:


1>*\src\game\bg_misc.c(204) : error C2099: initializer is not a constant

What am i doing wrong :frowning:

Im not a coder.
But if I’m right you want to replace Test1 with CombatErvaring?

And btw which line does cause the error? line 204? Is it Test1,? Give us more info.

You can’t do that for some reason, even though compilers are heralded as smart :smiley:

The most elegant solution here would be to #define the fields you want to use as they are merely simple strings. If you wanted to you could also map these to an enum fairly simply:

#define E_SKILLS_COMBATERVARING skCombatErvaring
#define E_SKILLS_HEAVYWEAPONS skHeavyWeapons

…

enum E_SKILLS
{
E_SKILLS_COMBATERVARING,
E_SKILLS_HEAVYWEAPONS
}

…

const char* skillNames[SK_NUM_SKILLS] = {
#E_SKILLS_COMBATERVARING,
#E_SKILLS_HEAVYWEAPONS
};

Which produces the same as

const char* skillNames[SK_NUM_SKILLS] = {
“skCombatErvaring”,
“skHeavyWeapons”
};

Notice this comes at the limitation of 1 string token, thus “HeavyWeapons” rather than “Heavy Weapons”.

And if you want something funkier maybe try X-Macros.

Don’t know if this will work on your compiler, but changing

const char* Test1 = "CombatErvaring";

to

const char Test1[] = "CombatErvaring";

works on GCC 4.3.

#include <stdio.h>

const char Test1[] = "CombatErvaring";

const char* skillNames[] = {
  Test1,
  "Engineering",
  "First Aid",
  "Signals",
  "Light Weapons",
  "Heavy Weapons",
  "Covert Ops",
  NULL
};

int main()
{
  int i;

  for (i = 0; skillNames[i] != NULL; ++i) {
    printf("%s
", skillNames[i]);
  }

  return 0;
}

I’ts working, many thx!

Just a side-question, is it possible to make 3dimensional arrays?
On php it goes this way:
<?php
$language[‘classes’][‘soldier’] = “Soldaat”;
$language[‘classes’][‘medic’] = “Hospik”;
$language[‘team’][‘allies’] = “Nederland”;
$language[‘team’][‘axis’] = “Duitsland”;

echo $language[‘team’][‘axis’];
?>

Would this be possible in C++

Thx
