我需要帮助。我正在编写一个Perl脚本来配置，编译和安装MPICH。最初的两个任务需要调用configure和make命令。我正在努力将选项传递给configure命令。请在下面找到我的最小示例：

#!/usr/local/bin/perl

use v5.38;
use autodie;
use strict;
use warnings;
use IPC::System::Simple qw(capturex);

# Writes text into given file
sub writef($fname, $txt) {
    open  my $fh, ">:encoding(UTF-8)", $fname;
    print $fh $txt;
    close $fh;
}

my $gnubin ='/opt/local/bin';
my $prefix ='/opt/mpich-4.1.2';
my $np     = 8;
my $txt;

print "Setting environment variables...\n";

$ENV{'FC'}  = $gnubin . '/gfortran';
$ENV{'F77'} = $ENV{'FC'};
$ENV{'CC'}  = $gnubin . '/gcc';
$ENV{'CXX'} = $gnubin . '/g++';

$ENV{'FFLAGS'} = '-m64 -fallow-argument-mismatch';
$ENV{'CFLAGS'} = '-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -m64';

mkdir 'build';
chdir 'build';

print "Configuring MPICH...\n";
my $conf_options = "--prefix=$prefix --enable-shared=no --enable-fast=O3,ndebug --disable-error-checking --enable-fortran=all --enable-cxx --disable-opencl --enable-romio --without-timing --without-mpit-pvars";
$txt = capturex('../configure', $conf_options);
&writef('c.txt', $txt);

print "Compiling MPICH...\n";
$txt = capturex('make', '-j', $np);
&writef('m.txt', $txt);

配置正确完成，但编译失败，并显示以下错误消息：

gcc: error: unrecognized command-line option '--without-timing'
gcc: error: unrecognized command-line option '--without-mpit-pvars/etc"'
gcc: error: unrecognized command-line option '--without-mpit-pvars/lib/libfabric"'

似乎我在capturex调用中遇到了一个问题。我怀疑当capturex命令传递给capturex命令时，$conf_options之间没有空格。我试图将配置选项声明为数组my @conf_options并在qq()操作符中传递字符串。但这失败了，出现了类似的错误。任何帮助都将不胜感激。
