Re: Potential spiped 1.4.0 release -- please test

[Dmitry Chestnykh <dchest@gmail.com>]

Hello,

Here's what I get on Xubuntu 14.04 with Atom CPU (doesn't support AESNI):


~/sources/spiped-1.4.0a $ make
export CFLAGS="${CFLAGS:--O2}"     \
	export LDADD_POSIX=`export CC="cc"; cd POSIX && command -p sh 
posix-l.sh`;	\
	export CFLAGS_POSIX=`export CC="cc"; cd POSIX && command -p sh 
posix-cflags.sh`;	\
	( export CC="cc"; cd libcperciva/cpusupport/Build && command -p sh 
cpusupport.sh ) > cpusupport-config.h;	\
	. cpusupport-config.h;				\
	for D in spiped spipe; do				\
		( cd ${D} && make all ) || exit 2;	\
	done
WARNING: POSIX violation: make's CC doesn't understand -lxnet
Checking if compiler supports X86 CPUID feature... yes
Checking if compiler supports X86 AESNI feature... yes, via -maes
/bin/sh: 5: .: cpusupport-config.h: not found
make: *** [all] Error 2


===================

cpusupport-config.h is here:

~/sources/spiped-1.4.0a $ cat cpusupport-config.h
#define CPUSUPPORT_X86_CPUID
#define CPUSUPPORT_X86_AESNI
#ifdef cpusupport_dummy
export CFLAGS_X86_AESNI="-maes"
#endif
