GLSL錯誤：非法非ASCII字符

我正在爲openGl寫一個頂點着色器。這是我的代碼：GLSL錯誤：非法非ASCII字符

#version 150 

in vec4 vPosition; 
in vec3 vNormal; 

out vec3 fN; 
out vec3 fE; 
out vec3 fL; 

uniform mat4 model_matrix; 
uniform mat4 view_matrix; 
uniform mat4 proj_matrix; 

uniform vec4 lightPos; 

void main() 
{ 
    vec3 pos = (view_matrix * model_matrix * vPosition).xyz; 
    vec3 lightPosInCam = (view_matrix * lightPos).xyz; 

    fN = normalize(view_matrix * model_matrix * vec4(vNormal,1.0)).xyz; 
    fE = normalize(vec3(0,0,0) - pos); 
    fL = normalize(lightPosInCam.xyz - pos); 

    gl_Position = proj_matrix*view_matrix*model_matrix*vPosition; 
}

然而，當我運行我的程序，這似乎是錯誤說，有一些非ASCII字符我}後，因爲在控制檯打印：

#version 150 

in vec4 vPosition; 
in vec3 vNormal; 

out vec3 fN; 
out vec3 fE; 
out vec3 fL; 

uniform mat4 model_matrix; 
uniform mat4 view_matrix; 
uniform mat4 proj_matrix; 

uniform vec4 lightPos; 

void main() 
{ 
     vec3 pos = (view_matrix * model_matrix * vPosition).xyz; 
     vec3 lightPosInCam = (view_matrix * lightPos).xyz; 

     fN = normalize(view_matrix * model_matrix * vec4(vNormal,1.0)).xyz; 
     fE = normalize(vec3(0,0,0) - pos); 
     fL = normalize(lightPosInCam.xyz - pos); 

     gl_Position = proj_matrix*view_matrix*model_matrix*vPosition;

對於我們所知道的你的着色器加載器是fubar。在[mcve]中編輯。 – genpfault

也許顯示您正在使用的代碼將着色器源提供給GL？似乎也許你的字符串沒有正確的空終止，或者你傳遞了不正確的長度。 – MuertoExcobito

一些看不見的unicode字符或控制代碼也是一個選項... – Spektre

However, when I run my program, it seems like the error says there is some nonASCII character after my }, because in console prints:

這是在OpenGL的着色器源字符串未正確終止零字節（NUL）和/或傳遞的緩衝區長度與源字符串的長度不匹配時遇到的典型錯誤。

解決方案：如果您沒有明確傳遞長度（即傳遞NULL參數爲length），請確保源字符串正確地以零終止。否則，請確保長度正確匹配源字符串緩衝區的長度。
