NSS 3.52.1 build failure on Linux

[Usha Nayak]

Hello,

I'm building NSS 3.52.1 on Linux of following configuration:


PLATFORM = x86_64
MODEL = Virtual Platform
PROCESSORS = 4
EFFECTIVE CPUs = 8
CLOCK SPEED =
TOTAL MEMORY = 7 GB

OSVERSION = LNX:CentOS Linux release 7.6.1810 (Core) 3.10.0-957.27.2.el7.x86_64
KERNEL PATCH = 3.10.0-957.27.2.el7.x86_64
COMPILERS = gcc-4.8.5-36.el7_6.2.x86_64

1) Downloaded NSS+NSPR source tarballs, unzipped
2) set following env variables:
setenv USE_64 1
setenv BUILD_OPT 1
setenv NSS_DISABLE_GTESTS 1
3) cd <nss directory>
4) Executed “gmake nss_build_all”

Got following error while building:
....
