If g++ installed, it can be not visible via PATH environment variable.

So the problem is: Why configure not detect out my system missing g++
until I run make, it told me `g++: command not found' ?

Or, just tell me, this worked, it is fine, and I will very happy to use.
btw: When I first install, ./configure is passed, but make is failed.
because I am not install gcc-c++. I have to install gcc-c++, reconfigure
again, make is passed. I thought if ./configure could detect gcc-c++
is not installed, will more good.
What C++ compiler did you have installed instead of gcc-c++ ?
I use CentOS 7.0 in VPS.
I just follow squid document from here:
http://wiki.squid-cache.org/SquidFaq/CompilingSquid
with following operation:
[root@vultr squid-3.5.12]# yum install -y perl gcc autoconf automake
make sudo wget
[root@vultr squid-3.5.12]# yum install openssl-devel
[root@vultr squid-3.5.12]# g++
-bash: g++: command not found
and then run my new config, Thanks for guide.
./configure --build=x86_64-linux-gnu \
--prefix=/usr \
--exec-prefix=/usr \
'--bindir=${prefix}/bin' \
'--sbindir=${prefix}/sbin' \
'--libdir=${prefix}/lib64' \
'--libexecdir=${prefix}/lib64/squid' \
'--includedir=${prefix}/include' \
'--datadir=${prefix}/share/squid' \
'--mandir=${prefix}/share/man' \
'--infodir=${prefix}/share/info' \
--localstatedir=/var \
'--with-logdir=${localstatedir}/log/squid' \
'--with-pidfile=${localstatedir}/run/squid.pid' \
'--with-swapdir=${localstatedir}/spool/squid' \
--sysconfdir=/etc/squid \
--with-openssl \
--with-default-user=squid \
--with-filedescriptors=16384
it worked. and end with Makefile created.
It seem like not c++ compile included initially, ./configure is not
detect out
for it for this OS, so no any error occur.
when I run make, it told me `g++: command not found'
