1,wget 'ftp://ftp.archlinux.org/other/pacman/pacman-4.1.2.tar.gz'下載軟件包
2，tar xvf pacman-4.1.2.tar.gz，解壓縮軟件
3，cd pacman-4.1.2/，進入代碼，執行./configure，提示沒有libarchive
4，執行sudo apt-get libarchive-dev安裝libarchive
5，再次執行./configure，通過
6，執行make，出錯

--------------------------------------------------------------------------------
7，gedit lib/libalpm/be_sync.c,代碼文件，找到代碼
-------------------------------------------------------------------------------
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
7，執行make&& make install,等待安裝完成。
