【中文标题】在 Ubuntu 14.04 中使用 SOIL【英文标题】：Using SOIL in Ubuntu 14.04 【发布时间】：2016-05-16 15:45:34 【问题描述】：我 时遇到了一些实际问题。我已经设法让 SOIL 在 Windows 环境中工作，并将代码从 Windows 移植到 ubuntu。
我确信我已经设法让 SOIL 安装在我的 Ubuntu 机器上。我有 libSOIL.a 和 libSOIL.so 文件以及 SOIL.h
然而，当我开始使用我的代码时，一切都出错了。这是我逐步构建的代码，因此在继续添加其他功能之前，我已经测试了代码片段。
我正在开发的代码非常简单（实际上，这只是为了尝试获得适用于许多平台的东西），它只是渲染一个围绕其中心旋转并具有纹理贴图的 3D 立方体。我希望使用 SOIL 来加载纹理。以前我已经使用我自己的例程加载纹理检查了这一切，这很好。一旦我将加载纹理的行更改为 SOIL 函数，它现在就会失败。
我使用的代码是
SOIL_load_OGL_texture("/home/ubuntu/Documents/OpenGL3/OpenGL_Basic_Engine/c2_4_DrawCubeTextureAdvanced/Textures/Crate.bmp", SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_MIPMAPS);
这是自此代码的上一个版本以来所做的唯一更改。
我通过简单的“fopen”和“ifelse”检查确保该文件是可打开的，我什至安装了 Code::Blocks，这样我就有了一个可以单步调试的调试器按行。当我的调试器进入 SOIL 函数并尝试单步执行该函数时，程序返回分段错误并退出，甚至没有将我发送到 SOIL 函数。
如果有人有任何想法，我将不胜感激，因为我已经为这个问题苦苦挣扎了好几个星期了！
干杯
*********编辑****************
让我们看看我现在是否可以在这里获得所有必需的信息（我不得不将机器移到我的 ubuntu 上以获得源代码）
首先我的代码是 C++（但我认为 SOIL 是用 C 编写的？-因此有两个标签）
失败的源文件如下：

else

if(pFile != NULL)
std::cout << "FILE OPEN" << std::endl;
fclose(pFile);
GLuint Texturetmp;
Texturetmp = SOIL_load_OGL_texture("/home/ubuntu/Documents/OpenGL3/OpenGL_Basic_Engine/c2_4_DrawCubeTextureAdvanced/Textures/Crate.bmp", SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_MIPMAPS);

我在终端运行的编译命令是：

返回的警告有几个type qualifiers ignored 或unused parameters。但是没有任何涉及 SOIL 函数调用或任何暗示在那之前可能会停止 SOIL 工作的问题（我知道）。

Simple OpenGL Image Library
A tiny c library for uploading images as
textures into OpenGL. Also saving and
loading of images is supported.
I'm using Sean's Tool Box image loader as a base:
http://www.nothings.org/
I'm upgrading it to load TGA and DDS files, and a direct
path for loading DDS files straight into OpenGL textures,
when applicable.
Image Formats:
- BMP load & save
- TGA load & save
- DDS load & save
- PNG load
- JPG load
OpenGL Texture Features:
- resample to power-of-two sizes
- MIPmap generation
- compressed texture S3TC formats (if supported)
- can pre-multiply alpha for you, for better compositing
- can flip image about the y-axis (except pre-compressed DDS files)
Thanks to:
* Sean Barret - for the awesome stb_image
* Dan Venkitachalam - for finding some non-compliant DDS files, and patching some explicit casts
* everybody at gamedev.net

我将libSOIL.a 存储在/usr/lib 中
我也尝试过将libSOIL.a 也存储在usr/local/lib 中，但这似乎无济于事。
SOIL.h 在usr/local/include中
希望现在这些信息足以让某人发现我的（新手）错误。
为大量代码道歉。
还必须访问 www.in2gpu.com，我一直在关注其教程，才能让我走到这一步。
干杯
【问题讨论】：
您是否使用-Wall -Wextra 选项编译您的代码？如果是，您确定没有警告吗？
我们需要很多更可靠的信息：1) 包含失败语句的文件的源代码 2) 两个库和 soil.h 头文件的实际位置。 3) 编译语句 4) 链接语句。如果没有这些关键细节，我们可能无法为您提供任何可靠的帮助，因为我们只能猜测。
您的源代码是用 C 还是 C++ 编写的？这是两种不同的语言，尽管大部分语法是通用的。由于类、STL、迭代器等原因存在巨大差异。--并且-- 在 C 中，函数、变量等的名称与 C++ 中的 mangled 不同。重要的是，这些库是如何编译/链接的？ soil.h文件的内容是什么？
建议将std::cout << "GLEW Version is 4.5 :) \n"; 等行替换为：std::cout << "GLEW Version is 4.5 :) << std::endl ;
注意：除非链接语句包含static 作为参数，否则不会使用libSOIL.a 文件。否则，将使用libSOIL.so 文件。
【参考方案1】：
我怀疑库等没有正确链接。
建议使用makefile，类似于：
CC := /usr/bin/g++
RM := /usr/bin/rm
SRCS := ./../BasicEngine/Engine.cpp \
./../BasicEngine/Core/Init/Init_GLUT.cpp \
./../BasicEngine/Core/Init/Init_GLEW.cpp \
./../BasicEngine/Managers/Models_Manager.cpp \
./../BasicEngine/Managers/Scene_Manager.cpp \
./../BasicEngine/Managers/Shader_Manager.cpp \
./CubeTextureAdvanced.cpp \
./../BasicEngine/Rendering/Models/Model.cpp \
./../BasicEngine/Rendering/Texture/TextureLoader.cpp
TEMP := $(basename $(SRCS))
OBJS := $(addsuffix .o, $(TEMP))
NAME := main
CFLAGS := -Wall -Wextra -Wconversion -std=gnu++11 -c
LFLAGS := -lglut -lGL -lGLU -lGLEW -lpthread -lX11 -lSOIL
.PHONY: all
all : $(NAME)
%.o:%.cpp
<tab>$(CC) $(CFLAGS) -o $@ $< -I.
$(NAME): $(OBJS)
<tab>$(CC) -o $@ $^ $(LFLAGS)
PHONY: clean
clean:
<tab> $(RM) -f $(OBJS)
<tab> $(RM) -f $(NAME)
注意：将<tab> 替换为制表符
然后使用类似的东西编译/链接：
make -f makefile
【讨论】：
makefile 可以通过生成dependencies 文件（带有.d 后缀）并将这一行：%.o:%.cpp 修改为：%.o:%.cpp %.d 来显着改进
如果要使用gdb或ddd进行调试，则在CFLAGS宏和LFLAGS宏的定义中添加-ggdb参数
我已尝试按照您的建议使用 make 文件，但当程序尝试调用 SOIL-load_OGL_texture 时，我仍然遇到分段错误。将%.d 添加到%.o:%.cpp 会导致make 文件失败:(在 Ubuntu 14.04 中使用 XAMPP 进行 Xdebug
