我正在尝试使用此处给出的说明编译OpenMP for OSX 10.9： Error enabling openmp - "ld: library not found for -lgomp" and Clang errors
但是我遇到了perl的问题：
make compiler=clang
omp_root=.
omp_os=macos
arch=intel64
compiler=clang
mic=no
mode=release
Created ./tmp directory
./tools/build.pl --arch=intel64 --mode=release lib inc common
./tools/build.pl --arch=intel64 --mode=release lib inc common

Unexpected error: undefined or empty host name; stopped at /Users/simon/Downloads/libomp_oss/tools/lib/Uname.pm line 403.
我的怀疑是，这是一个与Perl相关的问题。其中一条违规行写着：
my $fqdn = Net::Domain::hostfqdn(); # "fqdn" stands for "fully qualified doamain name".
if ($fqdn eq substr( $fqdn, 0, length( $fqdn ))
...
似乎Net::Domain::hostfqdn()没有返回任何内容。知道如何解决这个问题吗？
