Hi,
I have an issue with …\_export.h file creation with generate\_export\_header.
My targeted library is camel-cased (for instance MyLib).
On windows, the generated file is name MyLib\_export.h while on ubuntu 16.04, I get mylib\_export.h, even if I force BASE\_NAME to MyLib.
Do I do something wrong?
Why is the behavior different between OS?
Thanks,
A.

That is…strange. Can you provide a small reproducer example?
