新人贴， 不明白为啥一直无法run
还想问一下怎么看 error在哪 是否支持long long这种类型，pow函数是不是浮点型的？我目前只看到这两个不妥的地方。 /home/chenz15/chm6/main.c : 22: undefined reference to "pow"第22行，未定义的引用 "pow"
collect2: error: ld returned 1 exit status
这行经常出现于编译器停止工作的情况，ld啥意思我也不清楚
我怀疑是Makefile的问题，贴一下Makefile
gcc编译时需要加 -lm
似乎是你的编译器没有加
换一个编译器吧^_^

因为我平时习惯去用软件已有的功能直接run，所以想问一下哪里有教 如何在terminal 手动输入run相关的资料 250533160 发表于 2017-1-18 02:40

不是这个，是Makefile文件的内容 人造人 发表于 2017-1-18 02:49
不是这个，是Makefile文件的内容
#
#There exist several targets which are by default empty and which can be
#used for execution of your targets. These targets are usually executed
#before and after some main targets. They are:
#
# .build-pre: called before 'build' target
# .build-post: called after 'build' target
# .clean-pre: called before 'clean' target
# .clean-post: called after 'clean' target
# .clobber-pre: called before 'clobber' target
# .clobber-post: called after 'clobber' target
# .all-pre: called before 'all' target
# .all-post: called after 'all' target
# .help-pre: called before 'help' target
# .help-post: called after 'help' target
#
#Targets beginning with '.' are not intended to be called on their own.
#
#Main targets can be executed directly, and they are:
#
# build build a specific configuration
# clean remove built files from a configuration
# clobber remove all built files
# all build all configurations
# help print help mesage
#
#Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
#.help-impl are implemented in nbproject/makefile-impl.mk.
#
#Available make variables:
#
# CND_BASEDIR base directory for relative paths
# CND_DISTDIR default top distribution directory (build artifacts)
# CND_BUILDDIR default top build directory (object files, ...)
# CONF name of current configuration
# CND_PLATFORM_${CONF} platform name (current configuration)
# CND_ARTIFACT_DIR_${CONF} directory of build artifact (current configuration)
# CND_ARTIFACT_NAME_${CONF}name of build artifact (current configuration)
# CND_ARTIFACT_PATH_${CONF}path to build artifact (current configuration)

你用的软件是? 人造人 发表于 2017-1-18 03:44
你用的软件是?
Netbeans 250533160 发表于 2017-1-18 04:07
Netbeans
我认为是Cygwin的问题
建议去Cygwin官网下载最新的
我这边可以用了，在这之前我安装了最新的Cygwin
没用过这个软件
我用 Code::Blocks 可以正常执行 打印出结果 人造人 发表于 2017-1-18 06:40
