gcc warning: braces around scalar initializer

Question

I have look-up-table as defined below and I\'m making use of GCC. When I compile I get warnings as

warning: braces around scalar initializer

<

Answer 1

This is a scalar initializer: int foo = 3;
This is a scalar initializer with braces around it: int foo = {3};
This is an initializer of an array, which isn't scalar: int foo[] = {1, 2, 3};

The warning says that your struct has scalar initializers with braces around them:

typedef struct TECH
{

    float velocity1, velocity2;
...

struct TECH lut_model_1[2] = {{{296.001465},
    {74.216972},
...

Your code will work, it just has superfluous braces around its scalar initializers. If you take the braces out and format it a little more nicely (I'd put the first initializer on its own line) there will be nothing objectionable about it.
