Failed configure on x86_64...

[Armen]

Hey Folks,

I just tried building 1.2.6 on the following system:
Linux 2.6.24-19-xen #1 SMP x86_64 x86_64 x86_64 GNU/Linux

... and received the following error:
./configure --enable-64bit
checking build system type... Invalid configuration `x86_64-unknown-
linux-': machine `x86_64-unknown-linux' not recognized
configure: error: /bin/sh ./config.sub x86_64-unknown-linux- failed

... definitely looks like configure doesn't know about the specific
distribution I'm running:
cat /etc/redhat-release
CentOS release 5.2 (Final)

Aside from munging with configure, are there any cleaner ways of
fixing this problem?

Thanks!

You just need to specify the build target to configure; no munging
required:

./configure --enable-64bit --build x86_64-redhat-linux-gnu

So what do I specify as a build target here for 64 bit solaris 10, the
configure is detecting my system as sparc-sun-solaris2.10 but this
gives me 32 bit output I want 64 bit output?

Thanks

memcached-1.2.6 should identify the host correctly, so it should just
be a case of specifying --enable-64bit, but you can be explicit:

./configure --build=i386-pc-solaris2.11 --enable-64bit

A quick check of the created Makefile shows it is setting the CFLAGS
correctly:

$ grep 64 Makefile
install_sh_DATA = $(install_sh) -c -m 644
CFLAGS = -m64 -g -O2
INSTALL_DATA = ${INSTALL} -m 644

What would the build flag value be for x86_64 Fedora 10. Not real sure
how that string is generated.

I got it figured out. It appears that it may be a good idea to install
the Kernal Headers and GCC before you try to compile something.
