Hi all, I tried to configure jdk/jdk on MIPS, but I failed. The output of configure: ... checking for pandoc... no checking build system type... /home/loongson/aoqi/jdk/make/autoconf/build-aux/config.guess: unable to guess system type
This script, last modified 2012-02-10, has failed to recognize the operating system you are using. It is advised that you download the most up to date version of the config scripts from http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD and http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD If the version you run (/home/loongson/aoqi/jdk/make/autoconf/build-aux/config.guess) is already up to date, please send the following data and any information you think might be pertinent to <config-patc...@gnu.org> in order to provide the needed information to handle your system. config.guess timestamp = 2012-02-10 uname -m = mips64el uname -r = 3.10.0-693.5.2.ns7.032.mips64el uname -s = Linux uname -v = #1 SMP PREEMPT Fri Dec 29 16:42:48 CST 2017 /usr/bin/uname -p = mips64el /bin/uname -X = hostinfo = /bin/universe = /usr/bin/arch -k = /bin/arch = mips64el /usr/bin/oslevel = /usr/convex/getsysinfo = UNAME_MACHINE = mips64el UNAME_RELEASE = 3.10.0-693.5.2.ns7.032.mips64el UNAME_SYSTEM = Linux UNAME_VERSION = #1 SMP PREEMPT Fri Dec 29 16:42:48 CST 2017 configure: error: cannot guess build type; you must specify one configure exiting with result code 1 ... I think the reason is that uname returns mips64el. autoconf-config.guess can handle mips and mips64, but cannot handle mipsel and mips64el. I made a patch to pass the configure: $ hg diff diff -r 31361382634b make/autoconf/build-aux/autoconf-config.guess --- a/make/autoconf/build-aux/autoconf-config.guess Tue May 22 10:08:04 2018 -0700 +++ b/make/autoconf/build-aux/autoconf-config.guess Wed May 23 18:06:52 2018 +0800 @@ -977,6 +977,9 @@ eval `$CC_FOR_BUILD -E $dummy.c 2>/dev/null | grep '^CPU'` test x"${CPU}" != x && { echo "${CPU}-unknown-linux-gnu"; exit; } ;; + mipsel:Linux:*:* | mips64el:Linux:*:*) + echo ${UNAME_MACHINE}-unknown-linux-gnu + exit ;; or32:Linux:*:*) echo ${UNAME_MACHINE}-unknown-linux-gnu exit ;; I think ppc has the same problem, but it is fixed in make/autoconf/build-aux/config.guess.
