Note: Also available for Linux: linux-clang linux-icc

Note: Using static linking will disable the use of dynamically
loaded plugins. Make sure to import all needed static plugins,
or compile needed modules into the library.

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.

Note: The following modules are not being compiled in this configuration:
3dcore
3drender
webenginecore
webengine
webenginewidgets
pdf
pdfwidgets

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew’s llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

WARNING: Tool gperf is required to build QtWebEngine.

WARNING: QtWebEngine will not be built.

WARNING: QtPdf will not be built.

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

Check config.log for details.
./make.sh: line 8: -release: command not found
make: *** No targets specified and no makefile found. Stop.
make: Nothing to be done for ‘install’.

错误：
WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.

警告：QDoc无法编译，可能是因为无法找到libclang。这意味着您无法构建Qt文档。
在Linux系统上，您可以通过安装libclang-dev或libclang-devel软件包来安装libclang，具体取决于您的发行版。

解决方法：

sudo apt-get install libclang-dev #安装结束还存在该错误建议重启虚拟机。

undefined reference to

inline定义的内联函数最终会影响到交叉编译及生成库文件

错误问题在于，内联函数声明在调用内联函数之后，头文件中已经声明了部分函数，导致最终调用到内联
错误输出：(.text+0x13): undefined reference to `xxxx’ ->交叉编译

undefined reference to ‘xxxx’-> 生成的库文件调用后

问题解决：

成功代码：arm-linux-gnueabihf-gcc -fpic -O2 -c mqtt_2.c -o mqtt.o

失败代码：arm-linux-gnueabihf-gcc -fpic （-O0） -c mqtt_2.c -o mqtt.o
