吾在申威机器上试着编译cups，结果报错：
checking build system type... ./config.guess: unable to guess system type This script, last modified 2013-11-29, 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 (./config.guess) is already up to date, please send the following data and any information you think might be pertinent to <config-patches@gnu.org> in order to provide the needed information to handle your system. config.guess timestamp = 2013-11-29 uname -m = sw_64 uname -r = 4.19.90-sunway-desktop-talas uname -s = Linux uname -v = #11 SMP Fri Apr 17 15:04:05 CST 2020 /usr/bin/uname -p = unknown uname -X = nfo = /bin/universe = /usr/bin/arch -k = /bin/arch = sw_64 /usr/bin/oslevel = /usr/convex/getsysinfo = UNAME_MACHINE = sw_64 UNAME_RELEASE = 4.19.90-sunway-desktop-talas UNAME_SYSTEM = Linux UNAME_VERSION = #11 SMP Fri Apr 17 15:04:05 CST 2020 configure: error: cannot guess build type; you must specify one Makefile:11: Makedefs: 没有那个文件或目录 make: *** 没有规则可制作目标“Makedefs”。 停止。
人们不禁要问，这究竟是。。。还是。。。行了行了，还是问怎么办吧。正好申威人员指点，替换两个文件即可。吾试之，果然编译通过。
MISC_DIR=/usr/share/misc cp ${MISC_DIR}/config.guess . cp ${MISC_DIR}/config.sub .
