一个简单的错误：
onfigure: error: cannot guess build type; you must specify one
一个复杂的错误：
./configure ./config.guess: unable to guess system type This script (version 2018-02-24), has failed to recognize the operating system you are using. If your script is old, overwrite *all* copies of config.guess and config.sub with the latest versions from: https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess and https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub If ./config.guess has already been updated, send the following data and any information you think might be pertinent to config-patches@gnu.org to provide the necessary information to handle your system. config.guess timestamp = 2018-02-24 uname -m = loongarch64 uname -r = 4.19.0-loongson-3-desktop uname -s = Linux uname -v = #3200 SMP Thu May 13 10:17:27 CST 2021 /usr/bin/uname -p = unknown /bin/uname -X = hostinfo = /bin/universe = /usr/bin/arch -k = /bin/arch = loongarch64 /usr/bin/oslevel = /usr/convex/getsysinfo = UNAME_MACHINE = "loongarch64" UNAME_RELEASE = "4.19.0-loongson-3-desktop" UNAME_SYSTEM = "Linux" UNAME_VERSION = "#3200 SMP Thu May 13 10:17:27 CST 2021" config.sub: missing argument Try `config.sub --help' for more information. Unknown system , edit the configure Makefile:3: config.mak: 没有那个文件或目录 make: *** [Makefile:340：config.mak] 错误 1
解决办法，下载这两个文件，替换目录中的同名文件：
https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess
https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub
