我有一个Simulink模型，试图将其生成为C++ dll。我已经成功地编译了类似的模型，但是这给了我以下错误:
CGIR assertion 'fitsType<size_t>()' failed in 'b:\matlab\derived\win32\src\include\cg_ir\util_prim\../../../../../../src/cg_ir/export/include/cg_ir/util_prim/Size64.hpp:125'

### Build procedure for model: 'vcts_auxiSns' aborted due to an error.
我还在对话框中收到以下错误消息:
Unexpected or internal error encountered in "in CGIR: b:\matlab\derived\win32\src\include\cg_ir\util_prim\../../../../../../src/cg_ir/export/include/cg_ir/util_prim/Size64.hpp line 125: fitsType<size_t>()
". Please report this to MathWorks if you can cause it to recur
更新:
我现在已经能够找到问题所在，而且似乎是特定信号存在问题。下图显示了子系统的一小部分，只要允许红色框中的三个信号之一流通，就无法通过代码生成模型。一旦我破坏了所有三个信号，代码生成就会起作用。
不幸的是，我无法解决问题，因此我仍然渴望听到任何建议!
最佳答案
事实证明，这是Matlab 2011b中代码生成中信号传播的错误。根据Mathworks的说法，该问题在2012a和更高版本中得到了解决，因此我将其更新为2013b。现在，我不再遇到该错误。
