Possible GLSL errors are as follows:
Indicates an error that is not exposed via another specific error code, or indicates an internal problem with the operation of the compiler.
Long running programs can cause problems on some hardware, thus the GLSL compiler takes some measures to prevent these programs from running. One of the measures taken is to examine the length of the shader after the preprocessor has run. If this length is too long, then the shader is rejected.
The syntax at the given location did not match the required syntax of GLSL. There are a large number of reasons for why this can occur in both the preprocessing stage and the GLSL language stage. Here is a simple example:
attribute int int;
Since an identifier is expected after a type, this is an invalid declaration.
Identifiers must be declared before they can be used. The most common cause of this error is misspelling an identifier name, or using an identifier from an extension without enabling the extension. For example:
int x; y = 1;
A function was called with the incorrect number of arguments or with one or more of the arguments of the wrong type. Check that the number of arguments and their types in the function call match those of the declaration or definition of the function. For example:
void exampleFunction1(int x); void exampleFunction2() { exampleFunction1(1, 2); }
This error indicates that the indexing operator [] has been applied to an expression which does not support being indexed. The following code demonstrates how this error can occur:
int bar; return bar[0];
The compiler has determined that an index is out of range for the variable as it was declared.
In some cases (such as indexing a vector or an array) the bounds are known, and if the index is an expression that the compiler can calculate, it can determine if the index is out of range. The following code demonstrates how this error can occur:
int bar[3]; int baz = bar[4];
There are restrictions to what kind of index is allowed on both uniform and non-uniform variables. For a uniform variable, the index must be an integer constant expression. The following code demonstrates how this error can occur:
// The indexing of nonuniform vectors and arrays with expressions is illegal: vec4 b; float a; int c = 0; a = b[c]; // For fragment shader code, the indexing of uniform vectors and arrays with index expressions is illegal: uniform vec4 b; float a; int c = 0; a = b[c];
If the variable is not a unifom, then the index can include a loop index variable.
An index is not a constant in the shader code. The following shader code demonstrates how this error can occur:
uniform float myArray[100]; int i = 0; float a; a = myArray[i];
An argument is not a sampler in the shader code. A sampler is a set of GLSL uniform variable types that represent a particular texture used for texture sampling. Samplers are not allowed to be declared using a non-uniform type.
float my2dSampler; // Should be "uniform sample2D my2dSampler". vec2 coord; v4 returnData; returnData = texture2D(my2dSampler, coord); // Note that texture2D() is a built-in function.
Invalid macro name used in the shader code. The following code demonstrates how this error can occur:
#define get__squared(x) ( x * x )
Incompatible types in expression used within the shader code. The following code demonstrates how this error can occur:
float a; float b; if (a || b) { // Causes the error because the IF statement inputs are not Boolean. a = 1.0; }
Invalid if expression used in shader code. The following code demonstrates how this error can occur:
struct S { int x; }; bool b[2]; if (S) { // Causes the error because struct types are not allowed in selection IF expressions. return true; } else { return false; } if (b) { // Also causes the error because array types are not allowed in selection IF expressions. return true; } else { return false; }
Divide or mod by zero occurred in shader code. The following code demonstrates how this error can occur:
int a = 5 / 0; float a = 5.0 / 0.0; vec4 a; a[1 / 0] = 0.4;
Invalid preprocessor parameter count on macro occurred in shader code. Ensure that the number of arguments passed to the macro matches the expected number of parameters for the macro. The following code demonstrates how this error can occur:
#define myMacro(x) (x < 0) myMacro(1,2)
Maximum uniform vector count exceeded in shader code. The following code demonstrates how this error can occur:
uniform vec4 v1[1000000];
Maximum attribute vector count exceeded in shader code. The following code demonstrates how this error can occur:

Invalid condition in for loop within shader code. The following code demonstrates how this error can occur:
for (int i = 0; ; i++) { } // The conditional statement is missing. for (int i = 0; 1 > i; i++) { } // The conditional must have the variable on the left. for (int i = 0; i * 2; i++) { } // The conditional cannot use operators outside of comparison and equality operators.
Invalid iteration in for loop within the shader code. The following code demonstrates how this error can occur:
void exampleFunction1() { for (int i = 0; i < 1; ) { // Missing increment/decrement statement. } } void exampleFunction2() { for (int i = 0; i < 10; i *= 2) { // The += and -= operators may be used but not *= or /= } } void exampleFunction3() { int x = 10; for (int i = 0; i < 10; i += x) { // The x variable must be a constant. } }

// Structure and array types cannot be vector or tensor constructor arguments: struct S { int i; } s; vec2 v1 = vec2(s); int i[2]; ivec2 v2 = ivec2(i);

Be aware that the error code/message is subject to macro expansion.
