c++ - CGIR 断言 'fitsType()' 失败

Question

我有一个 Simulink 模型，我试图将其生成为 C++ dll。我已经成功地编译了类似的模型，但是这个给了我以下错误:

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:

我现在已经定位到问题了，好像是某个信号有问题。下图显示了一个子系统的一小部分，只要允许红色框中三个信号中的一个流动，模型就无法生成代码。一旦我破坏所有三个信号，代码生成就会开始。

不幸的是，我没能解决这个问题，所以我仍然渴望听到任何和所有的建议!

Answer 1

事实证明这是 Matlab 2011b 代码生成中信号传播的一个错误。根据 Mathworks 的说法，它在 2012a 及以后得到解决，所以我更新到 2013b。现在我不再收到该错误。
