icecream – configure: error: Could not figure out what C++ library this is

今日在尝试编译libreoffice时，据说启用icecream能够加速编译，于是就在将一台Fedora 26主机设置为scheduler，这台Fedora主机和另一台Ubuntu主机上启用iceccd守护进程。通过icecc-monitor能够看到两台机器上的icecream均正常。但是当在libreoffice源代码下的 autogen.input 中加入 –enable-icecream 选项后，运行autogen.sh出现以下错误：

经过在irc频道询问，最终找到了如下解决办法：原来，Fedora默认将icecream的c++ wrapper安装到了 /usr/libexec/icecc，在 autogen.input 中加入 –with-gcc-home=/usr/libexec/icecc 重新运行autogen.sh即可解决。

When compile libreoffice in Fedora with icecream, you may encounter the above error message. To fix the above error, add the option “–with-gcc-home=/usr/libexec/icecc” in your autogen.input file.
