编译配置源码时提示：
[wlf@wlf185 otp_src_21.3]$ ./configure --prefix=/home/wlf/erlang Ignoring the --cache-file argument since it can cause the system to be erroneously configured Disabling caching checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking for gcc... gcc checking whether the C compiler works... no configure: error: in `/home/wlf/otp_src_21.3': configure: error: C compiler cannot create executables See `config.log' for more details
看下config.log：

提示找不到ld，我们确认下：
[wlf@wlf185 otp_src_21.3]$ which ld /usr/bin/which: no ld in (/usr/local/mongodb/bin:/opt/jdk/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/wlf/.local/bin:/home/wlf/bin)
确实没有ld这个，难道没装ld？那就切换到root装一下吧：
[root@wlf185 bin]# yum install binutils Loaded plugins: product-id, search-disabled-repos, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Package binutils-2.25.1-22.base.el7.x86_64 already installed and latest version Nothing to do [root@wlf185 bin]# ld -v -bash: ld: command not found
见了鬼了，ld装着呢，就是没法用。重装吧：
[root@wlf185 bin]# yum reinstall binutils Loaded plugins: product-id, search-disabled-repos, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

好了，切回wlf用户重新编译配置。
