器件型号： TMS320F2800157-Q1
Thread 中讨论的其他器件： C2000WARE、 SysConfig

我在使用 TI 编译器在 CCS 上构建 F2800157 目标时遇到了一个奇怪的问题、导致 dcsm.cmd 文件在链接器调用中被包含两次。

如果我清理并编译、或只是重新编译工程、没有链接错误：

但是、如果我在一行中编译两次工程、会收到以下（截断）链接器错误：

主要的区别是重建也突然包含"../src/bsp/include/bsp/dcsm.cmd",这显然是一个错误,因为同一个文件已经包含一次: -l"C:/Projects/my_project/hardware_c/src/bsp/include/bsp/dcsm.cmd"

通过查看工程属性、我找不到任何看起来负责包含 dcsm.cmd 条目的位置。需要注意的是、syscfg 生成的文件位于“ c：/Projects/my_project/hardware_c src /bsp/include/bsp/ “、那么该路径可能是自动扫描的、并且添加了已知的文件吗？

我的假设是在下配置了自动扫描的位置 “Projects Properties“->"Build"->"C2000 Linker"->"File“ Linker"->"File Search“ Search Path"“ Path"</s>“ ““但是、除了我自己的库之外、我在该位置设置了以下文件集、其中没有一个文件可以控制其中的任何一个文件。

  将库文件或命令行文件作为输入 (--library,-l)：
   $｛INHERITED_LIBRARS｝
   $｛COM_TI_C2000WARE_libraries｝
   libc.a

例程

到库搜索路径 (--search_path、-i)：
   $｛INHERITED_LIBRARY_PATH｝
   $｛COM_TI_C2000WARE_LIBRARY_PATH｝
   $｛CG_TOOL_ROOT｝/lib
   $｛CG_TOOL_ROOT｝/包含
   $｛C2000WARE_ROOT｝
   $｛PROJECT_BUILD_DIR｝/syscfg

我尝试从编译中排除文件，这使得第二个编译成为可能，因为该条目从链接器调用行中忽略了 — 但此修复只会持续到发出清理命令为止。 dcsm.cmd "../src/bsp/include/bsp/dcsm.cmd":-(

发生什么事了？我如何确保同一个自动生成的文件不会（自动）包含两次？
