新人贴， 不明白为啥一直无法run

还想问一下怎么看 error在哪

361628653

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。

zealstar

/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

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)
#     CND_PACKAGE_DIR_${CONF}    directory of package (current configuration)
#     CND_PACKAGE_NAME_${CONF}   name of package (current configuration)
#     CND_PACKAGE_PATH_${CONF}   path to package (current configuration)

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

这，只是开始→

我用 Code::Blocks 可以正常执行 打印出结果
