Make fails about rma HOT 4 OPEN

Hi there,
I'm not sure, can you post the output of make?

from rma.

After running the make in su mode, number of error decreases. Now the error is:
clang++ -std=gnu++17 -stdlib=libc++ -c -DHAVE_LIBNUMA -DHAVE_LIBPAPI -DNDEBUG -I../ -Wall -Wno-sign-compare -Wno-overloaded-virtual -O3 -march=native -mtune=native -fno-stack-protector ../pma/driver.cpp -o objects/pma/driver.o
../rewired_memory.cpp:73:91: error: use of undeclared identifier 'MFD_HUGETLB'
m_handle_physical_memory = memfd_create(id.c_str(), configuration::use_huge_pages() ? MFD_HUGETLB : 0); // miscellaneous.hpp
^
../abtree/dense_array.cpp:178:57: error: use of undeclared identifier 'MFD_HUGETLB'
int memfd_flags = configuration::use_huge_pages() ? MFD_HUGETLB : 0;

Hi Tamal,

thanks for the response.
MFD_HUGETLB is Linux 4.14+ and it should be defined in the file <linux/memfd.h>, typically /usr/include/linux/memfd.h. Can you confirm whether you are using an earlier kernel?

You can define the macro on your own just to get rid of the error:
#define MFD_HUGETLB 0x0004U

What other errors do you get outside the root environment ? :-)

Thanks a lot. Replacing MFD_HUGETLB with 0x4 works fine.
