C/C++项目不是在linux中构建的,而是在windows上构建和运行的

glad glfw shared-libraries linux c++

Seon Il · 技术社区 · 1 年前

我有一个工作空间,里面有两个项目“Physx2D”和“SandBox”。第一个构建在共享库中,第二个构建在控制台应用程序中。SandBox需要Physx2D库,并设置为启动项目。

我正在使用glfw3库,很高兴使用opengl函数。

问题是该项目在windows上成功构建和运行,但在linux上失败了。更详细地说,Physx2D库构建成功。这期杂志是在编辑SandBox之后发行的。它无法链接,并引发警告和多个链接错误,所有这些错误都表示Physx2D库中函数中“glad_******”的未定义引用。例如。

警告:

/usr/bin/ld: ../bin-int/Debug-linux-x86_64/SandBox/main.o warning: relocation against 'glad_glClearColor' in read-only section '.text._ZN7Physx2D6Window10FillScreenENS_5vec4IfEE[_ZN7Physx2D6Window10FillScreenENS_5tvec4IfEE]'

错误:

/usr/bin/ld: ../bin-int/Debug-linux-x86_64/SandBox/CA_gpu.o : in function 'Physx2D::Shader::use()':
..project_directory_of_sandbox ../Physx2D/src/renderer/shader.h:24: undefined reference to 'glad_glUseProgram'

在链接过程中会抛出多个遵循相同模式的错误。

我正在使用premake为gmake2生成项目makefile。

这是我的预制脚本。

    filter "configurations:Release"
            defines {"PHSX2D_RELEASE", "PHSX2D_ASSERT_ENABLE"}
            optimize "on"

我认为这个问题与项目设置无关。在快速查看了这些问题并进行了几次搜索后,我发现问题是在链接过程中找不到在greed.h中声明的函数的定义。我在Physx2D项目中的一个文件夹中有一个高兴的.c,我已经在premakescript的项目文件中包含了这个文件夹。此外,如果问题是为什么在构建Physx2D时没有产生任何问题。

如果这不是问题所在,那么问题是什么以及如何解决。
