glTexImage2D 上的 Sigabrt
Sigabrt on glTexImage2D
我周末离开时我的代码处于工作状态，自从我回来后，我一直随机收到此错误。有时它 运行s 和我的 android 项目有效，有时却无效。我目前正在研究 NDK 并试图让 Freetype Lib 工作。通过阅读此堆栈跟踪，这里是我的 "relevant" 代码：
void TextRenderer::SetupGlyphs(std::string fontPath, int size){
if(shadersInitialized == 0)
CreateShader();
glUseProgram(this->shader);
// FreeType
FT_Library ft;
if (FT_Init_FreeType(&ft))
__android_log_print(ANDROID_LOG_INFO, "SetupGlyphs", "ERROR::FREETYPE: Could not init FreeType Library.");
FT_Face face;
if (FT_New_Face(ft, fontPath.c_str(), 0, &face))
__android_log_print(ANDROID_LOG_INFO, "SetupGlyphs", "ERROR::FREETYPE: Failed to load font: %s", fontPath.c_str());
FT_Set_Pixel_Sizes(face, 0, size);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
for (GLubyte c = 0; c < 128; c++){
if(FT_Load_Char(face, c, FT_LOAD_RENDER)){
printf("ERROR::FREETYPE: Failed to load Glyph\n");
continue;
}

为什么它只是偶尔失败？
编辑：通过日志记录我发现它在 ascii 代码 35 的字符处失败。
Edit2：我不知道为什么，但它会随机卡在不同的角色上。有时，甚至，它根本不会卡住，只会编译 运行...我什至不知道了。
因此，对于可能发现此 post 的任何人，我在网上搜索了几个小时，终于找到了答案。 Freetype 没有通过 GL_RGB 对齐（至少在我的项目中没有），而是通过 GL_LUMINANCE 对齐。通过更改 glTexImage2D 中的此类内容，我解决了上述问题，以及我遇到的一些奇怪的图形错误。
