解决方案：
Simply do the following command:
df /tmp
You should see something close to 100% of utilization for the partition hosting /tmp.
Solution 1: if possible, clean up your /tmp directory, or any other directory located on the full disk partition. Remove some temporary files, etc. If you are unsure, ask your local smiling sysadmin.
Solution 2: it is quite possible that the size of the partition hosting /tmp is too small for the kind of utilization you are doing with your workstation. It happens. On my workstation, I always make sure I have a large /tmp.
Simply read the man page for g++. Look up the section where they talk about the environment variable TMPDIR.
Set your TMPDIR environment variable to a directory located on your 35GB free disk space. Restart your compilation.
That should do the trick.
我设置TMPDIR export TMPDIR=/root ,问题解决。
TMPDIR wikipedia解释：
TMPDIR is the canonical Unix environment variable that should be used to specify a temporary directory for scratch space. Most Unix programs will honor this setting and use its value to denote the scratch area for temporary files instead of the common default of /tmp[1][2] or /var/tmp.[3]
Other forms sometimes accepted are TEMP, TEMPDIR and TMP, but these alternatives are used more commonly by non-POSIX operating systems or non-conformant programs.
TMPDIR is specified in various Unix and similar standards, e.g. per the Single UNIX Specification.[4]
unset TMPDIR
