源码安装SpamAssassin 3.4.1出错spamc/configure.pl: Can’t exec `version.h.pl’

先将SA依赖组件安装好后，进行编译安装：

[root@mail Mail-SpamAssassin-3.4.1]# /usr/local/perl5/bin/perl Makefile.PL PREFIX=/usr/local/spamassassin CONTACT_ADDRESS="postmaster.zjtxt.com" DATADIR=/data/mail/spamassassin
[root@mail Mail-SpamAssassin-3.4.1]# make

编译时会报如下错误：

..
"/usr/local/perl5/bin/perl" spamc/configure.pl --prefix="/usr/local/spamassassin" --sysconfdir="/usr/local/spamassassin/etc/mail/spamassassin" --datadir="/data/mail/spamassassin" --enable-ssl="no"
cd spamc
/usr/local/perl5/bin/perl version.h.pl
do "version.h.pl" failed, '.' is no longer in @INC; did you mean do "./version.h.pl"? at spamc/configure.pl line 72.
spamc/configure.pl: Can't exec `version.h.pl': No such file or directory at spamc/configure.pl line 74.
make: *** [spamc/Makefile] 错误 2
[root@mail Mail-SpamAssassin-3.4.1]#

提示找不到文件，可此文件确实存在：

[root@mail Mail-SpamAssassin-3.4.1]# ls spamc/version.h.pl 
spamc/version.h.pl
[root@mail Mail-SpamAssassin-3.4.1]#

经过查找，很多人都出现过此问题，后在此网站上找到解决方法。

按其提示，修改spamc/configure.pl源文件，忽略version.h的存在检查：

[root@mail Mail-SpamAssassin-3.4.1]# vim +74 spamc/configure.pl

# Create version.h platform independently.
print join(' ', $Config{'perlpath'}, "version.h.pl") . "\n";
{
  # Do the same thing as for the preprocessor below.
  package version_h;
  my $Z = $0;
  local $0    = "version.h.pl";
  local @ARGV = ();
  # Got to check for defined because the script returns shell error level!
  unless (defined do $0) {
#    $0 = $Z;
#    die $@ ? $@ : "Can't exec `version.h.pl': $!";
    $0 = "/usr/local/src/Mail-SpamAssassin-3.4.1/spamc/version.h.pl";
    $Z = $0;
    $Z;
  }
}

上面一段的工作本来是要创建spamc/version.h文件，现在需要手工创建：

[root@mail Mail-SpamAssassin-3.4.1]# ls spamc/version.h

/* version.h. Generated by version.h.pl. */
/* version.h.in. template for version.h.pl, called from configure.pl. */

#define VERSION_STRING "3.4.1"

然后即可正常编译安装：

[root@mail Mail-SpamAssassin-3.4.1]# make -j `cat /proc/cpuinfo | grep processor | wc -l` && make install
