[LLVMdev] LLVM build is failed giving Path.inc:714: error: ‘unlink’ was not declared in this scope

[janarbek]

Does someone have a solution for this problem ?
I am using gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5)  and I have tried several versions of LLVM including llvm 2.9 final. I am getting same error again and again.

I have successfully build the llvm on another machine with gcc version of 4.3. 

Thanks in advance.

The patch does inseret unistd.h as below. However, I am still getting exactly same error when I do make.if you have any suggestions please let me know.

#if HAVE_UNISTD_H
#include <unistd.h>
#endif

That means it was applied.

In that case, I have no idea how you could run into the error you're
seeing; unlink should be defined in unistd.h.
