undefined symbol: rleIouInterUnion

[lala11-byte]

I'm encountering an issue with a modified version of pycocotools. Here's my situation:

The original pycocotools compiles and runs perfectly fine
I made some modifications to the RLE-related functions
Compilation completes successfully with:
python setup.py build_ext --inplace
But when I try to use my modified version, I get:
gcc exit errow
Here's what I've tried:
Verified the function exists in the source files
Checked that all modified files are being compiled
Compared compilation commands between original and modified versions
The error suggests the symbol isn't being properly exported in my modified version.

I encountered an error while compiling the modified pycocotools file:
error: command 'gcc' failed with exit status 1
The root cause was incorrect file copying. I had copied the maskApi.c and maskApi.h files improperly, which led to missing necessary headers or type definitions, causing the gcc compiler to fail.
I met the error :error: command 'gcc' failed with exit status 1 when built de modified file pycocotools now . Hope you can help me.
