How to fix Simulink c code generator case sensitivity issue?

I am trying to include a c file in Simulink. In Configuration Parameters -> Simulation Target I have added the appropriate files and headers. When I selece Validate custom code Simulink returns what I guess is a compiler error:

libcpp: Can't open input file ..\\slprj\\_slcc\\koazhuz13p6xrvzw4cvuy\\slcc_interface_koazhuz13p6xrvzw4cvuy.c

I believe this is due to case sensitivity, as the actual folder name is kOazhUz13p6xRVzW4CvUY and if I rename it to the lower case i.e. koazhuz13p6xrvzw4cvuy the compiler seems to get further before throwing another error. Is there a way I can get Simulink to stop generating case variable folder names or otherwise fix this issue? Thanks!

@Christian Edgar What is the error that pops up after renaming the folder to lowercase?

Hi @Christian Edgar,

i had a similiar issue when using custom C files to generate code for my model in Simulink. A workaround for me was to move all included source and header files to a subdirectory inside the custom code generation folder.

Some other possible workarounds are:

• Renaming the code files/folders to lowercase.
• Avoid using custom folders for cache and code generation.

Hope this is helpful!
