主题中讨论的其他器件：RM46L850、 HALCOGEN

GCC ARM 编译器使用多库、其中链接器根据传递给链接器的选项组合选择要链接的库。 例如、对于通过 CCS "安装 GCC ARM 编译器工具"安装的 GNU v6.3.1、可用的库为： 

C:\ti\ccs1040\ccs\tools\compiler\gcc-arm-none-eabi-6-2017-q1-update\bin>arm-none-eabi-gcc.exe --print-multi-lib

当设置新项目时、发现 CCS 没有传递链接器的所有编译器运行时选项、这会导致链接器错误。

例如 、在 CCS 10.4.0.00006中使用  GNU v6.3.1作为编译器、为 RM46L850创建一个新项目。

在 Build -> GNU Compiler -> Runtime options 上、为-mCPU、-mfloat-abi 和-mfpu 输入值：

编译失败、链接器出现错误：

**** Build Finished ****

问题是 、虽然已为编译 器设置了-mcpu=cortex-r4 -mfloat-abi=hard -mfpu=vfpv3-D16选项、但 CCS 仅将这些选项中的-mfloat-abi=hard 传递给链接器。 这导致链接器 multi-lib 选择了不兼容的库、从而导致错误。

若要使工程链接到 Build -> GNU Linker -> Miscellaneous 添加 了-mcpu=cortex-R4和 -mfpu=vfpv3-D16选项：

CCS 不会自动将项目中选择的所有编译器运行时选项传递给链接器、这是否是一个错误？

    切斯特、

    它当然看起来像是 CCS 中的一个错误。  Ki 明天会回来、可以看看。

    此致、

    切斯特、您好！

    它确实看起来像是一个错误。 我可以使用 GCC 6.3.1来重现此问题。 正如您提到的、只有"mfloat-abi=hard"看起来会传递给链接器。 有趣 的是、当我删除该选项时、我注意到(仅)"-mcpu=cortex-r4"会传递给链接器。

    当我使用 GCC 9.2.1时、我会看到传递给链接器的行为不同。 但总是缺少一些东西。  

    我将会提交一个错误

    谢谢

     如果有用、https://github.com/Chester-Gillon/E2E_example_projects/tree/master/RM46L850_GCC_halcogen_cpp 是我在中发现此问题的项目。 在签入项目中 、-mcpu=cortex-R4和-mfpu=vfpv3-D16选项已手动添加到杂项链接器选项中。
