------------ 问题1
编译安装apr-util-1.5版本时出现如下错误
libtool: error: 'crypto/crypt_blowfish.lo' is not a valid libtool object
这种情况有可能是前面编译时有缓存，用make clean清除一下再次编译安装
---------------问题2
HTTP编译时出现如下错误可能是由于apr-util版本太高，换成1.5的版本试试
/usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_GetErrorCode'

NGINX编译时出现问题
src/http/ngx_http_script.c:698:18: error: cast between incompatible function types from ‘size_t ()(ngx_http_script_engine_t )’
{aka ‘long unsigned int ()(struct
[-Werror=cast-function-type]
这个错误把MakeFile文件中的werror这个删除调，然后清理编译缓存，make clean 重新编译
---------------问题4
在编译安装mariadb10.1.43时出现：cc: fatal error: Killed signal terminated program cc1
这种情况应该是内存不足造成的，我从网上看到的方法是使用交换内存，但是由于树莓派是直接用TF卡安装的，开始没有设置swap，后来我设置了还是报这个错误----内部编译错误
后来我的解决方法不安装Mariadb数据库，改用MySQL5.6，结果是编译成功了的。
--------------问题5
编译PHP时出现：
make: *** [Makefile:584: ext/openssl/openssl.lo] Error 1
error: storage size of ‘cipher_ctx’ isn’t known
4848 | EVP_CIPHER_CTX cipher_ctx;
这种情况是OpenSSL最新版本接口调用变化所致，更换PHP为较新版本试一下或者使用OpenSSL较旧的版本
PHP编译安装配置：
./configure --prefix=/usr/local/php5.3 --enable-mbstring --enable-xml --enable-fpm --enable-sockets --with-mysql=mysqlnd \
--with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib \
--with-libxml-dir=/usr --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 \
--with-mysql=/usr/local/mysql --enable-pcntl --enable-dba --with-gd --enable-gd-native-ttf --enable-gd-jis-conv --enable-ftp \
--enable-embedded-mysqli --with-webp-dir --enable-debug --enable-bcmath --with-ldap --with-gettext1
NOTE树莓派编译安装时出现：onfigure: error: can not guess host type; you must specify one，这种情况除了要加--build=arm-linux,还有加上--host=localhost
Php7.1.33版本要求OpenSSL必须大于1.0.1版本：--with-openssl[=DIR] Include OpenSSL support (requires OpenSSL >= 0.9.6)
要求zlib大于1.2.0.4版本 --with-zlib[=DIR] Include ZLIB support (requires zlib >= 1.2.0.4)

编译时出现：freetype-config not found错误时，应该是libfreetype-dev版本比较高，在Ubuntu19.10上是版本6.可以下载2.8.1解决这个问题
