Help,How can I fixd this error?

[Spudz76]

CentOS?

[hqylwrx]

centos 6.9 64bit

[JerichoJones]

@hqylwrx Did you ever get this resolved?

[Spudz76]

If you really must CentOS, then I hear 7.4 is closest to compatible with xmr-stak and its dependencies and the drivers that work well. Anything older won't have the proper compiler or headers for C++ 11 standards (GCC 5.4 but even better 5.5 or 5.6 or newer, but clang 3.8 or newer also works, but neither is likely easily available on CentOS 6.x)

But friends don't let friends CentOS, srsly.

@hqylwrx It seems that your system doesn't define this. Try to add this code, #define MAP_HUGETLB 0x0040000

[Spudz76]

I would and have defined it as 0 on systems where it is unsupported (aka not already in the headers) Probably have to do the same to MAP_POPULATE
