Ubuntu如何安装Pacman

1,wget 'ftp://ftp.archlinux.org/other/pacman/pacman-4.1.2.tar.gz'下载软件包
 2，tar xvf pacman-4.1.2.tar.gz，解压缩软件
 3，cd pacman-4.1.2/，进入代码，执行./configure，提示没有libarchive
 4，执行sudo apt-get libarchive-dev安装libarchive
 5，再次执行./configure，通过
 6，执行make，出错
 -------------------------------------------------------------------------------
  CC      libalpm_la-be_sync.lo
 be_sync.c: In function '_alpm_validate_filename':
 be_sync.c:499: error: 'PATH_MAX' undeclared (first use in this function)
 be_sync.c:499: error: (Each undeclared identifier is reported only once
 be_sync.c:499: error: for each function it appears in.)

 --------------------------------------------------------------------------------
 7，gedit lib/libalpm/be_sync.c,代码文件，找到代码
 -------------------------------------------------------------------------------
 static int _alpm_validate_filename(alpm_db_t *db, const char *pkgname,
        const char *filename)
 {
    size_t len = strlen(filename);
 
    if(filename[0] == '.') {
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is illegal\n"), db->treename, pkgname);
        return -1;
    } else if(memchr(filename, '/', len) != NULL) {
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is illegal\n"), db->treename, pkgname);
        return -1;
    }
else if(len > PATH_MAX) {
 
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is too long\n"), db->treename, pkgname);
        return -1;
 
    }
    return 0;
 }

 修改如下
 -------------------------------------------------------------------------------
 static int _alpm_validate_filename(alpm_db_t *db, const char *pkgname,
        const char *filename)
 {
    size_t len = strlen(filename);
 
    if(filename[0] == '.') {
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is illegal\n"), db->treename, pkgname);
        return -1;
    } else if(memchr(filename, '/', len) != NULL) {
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is illegal\n"), db->treename, pkgname);
        return -1;
    }
/*
 else if(len > PATH_MAX) {
 
        errno = EINVAL;
        _alpm_log(db->handle, ALPM_LOG_ERROR, _("%s database is inconsistent: filename "
                    "of package %s is too long\n"), db->treename, pkgname);
        return -1;
 
    }
 */
    return 0;
 }

 保存，退出
