工具/软件：

您好：

我想将工具链版本从 ti-cgt-armllvm_3.2.LTS 切换到 ti-cgt-armllvm_4.0.3.LTS 、但无法编译与所使用的相同代码 3.2.2.

在4.0.x 中、编译失败、并出现以下错误：

/opt/ti-cgt-armllvm_4.0.0.LTS/include/c++/v1/cctype:43:5: error: <cctype> tried including <ctype.h> but didn't find libc++'s <ctype.h> header.           This usually means that your header search paths are not configured properly.            The header search paths should contain the C++ Standard Library headers before           any C Standard Library.

This usually means that your header search paths are not configured properly.           The header search paths should contain the C++ Standard Library headers before           any C Standard Library, and you are probably using compiler flags that make that           not be the case.

问题似乎是由包含路径太多引起的。我已经通过使用-E -v 调用/opt/ti-cgt-armllvm_4.0.0.LTS/bin/tiarmclang 来检查了用于编译的包含路径头文件应该会显示在编译输出中、我可以看到：

ignoring duplicate directory "/opt/ti-cgt-armllvm_4.0.0.LTS/lib/clang/18/include"
#include "..." search starts here:
#include <...> search starts here:

my include paths....

 /opt/ti-cgt-armllvm_4.0.0.LTS/include/armv7r-ti-none-eabihf/c++/v1
 /opt/ti-cgt-armllvm_4.0.0.LTS/include/c++/v1
 /opt/ti-cgt-armllvm_4.0.0.LTS/lib/clang/18/include
 /opt/ti-cgt-armllvm_4.0.0.LTS/include/c

当我限制用于编译的包含路径数时、问题就消失了。

问题也出现在 4.0.3中

Include 路径编号的数量是否存在任何已知限制？您能解决我这个问题吗？

请删除每个 -i 引用编译器提供头文件的目录的选项。更多详细信息、请参阅 tiarmclang 在线手册的"包含选项"部分。

谢谢。此致、

问题似乎是由 mcu_plus_sdk_am62x_11_00_00_16/source/drivers/device_manager/rm_pm_hal/rm_pm_hal_src/pm/include 和 mcu_plus_sdk_am62x_11_00_00_16/source/drivers/device_manager/rm_pm_hal_hal/包含 src_pm/hal_types 所引起的。其中包含 ctype.h 和 errno.h

感谢您的提示。
