# Intel(R) Graphics Compute Runtime for OpenCL(TM)
|
|
|
|
|
|
|
|
|
|
## Known Issues and Limitations
|
|
|
|
|
|
|
|
|
|
OpenCL compliance of a driver built from open-source components should not be
|
|
|
|
|
assumed by default. Intel will clearly designate / tag specific builds to
|
|
|
|
|
indicate production quality including formal compliance. Other builds should be
|

|
|
|
considered experimental.
|
|
|
|
|
|
|
|
|
|
### Build limitations
|
|
|
|
|
|
|
|
|
|
While NEO can be compiled with various clang/gcc compilers, to compile the whole stack the following are required:
|
|
|
|
|
* clang-4.0
|
|
|
|
|
* llvm-4.0
|
|
|
|
|
* gcc < 7.0
|
|
|
|
|
* Python 2.7
|
|
|
|
|
|
|
|
|
|
