ACE六步配置:
一、于http://download.dre.vanderbilt.edu/下载相应平台的ACE包,这里写道如果是windows平台下载.zip包,其他平台下载.gz或bz2包,我是乌布图选择了个gz包,我用的是6.0.0;
二、解压包,里面有个ACE-INSTALL.html文档,在线页面地址为http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/ACE-INSTALL.html#unix,按此过程,进行接下来的安装配置;
三、终端命令行内,在所解压的目录(例如/home/administrator/libs/ACE_wrappers)内,建立目录objdir(例如/home/administrator/libs/ACE_wrappers/objdir),并进入之,如下命令:
mkdir objdir
cd objdir
四、运行命令../configure,这个命令有个参数选项,具体参看资料吧,懒得啃英文也木法,谁让代码都是字母呢;
五、运行make命令,编译库;
六、运行make install命令完成安装。
ACE配置中make所遇到的问题:
1.如果按照上述说明中的安装方法,第五步可能会出现问题,一般在自行编译源码所碰到的错误都会是系统缺少软件包所致,我所遇到的问题是跟ssl有关系,告警如下:
http://www.cnblogs.com/../ace/SSL/SSL_Asynch_BIO.h:29:25: error: openssl/bio.h: 没有那个文件或目录
原因:缺少openssl或者找不到openssl的头文件;
解决:去http://www.openssl.org/source/下载latest程序,经过一番./configure、make、make install安装套路,还有一步为做个链接:
cd /usr/include
ln -s /usr/local/ssl/include/openssl openssl
2.又遇到错误,如下:
home/knight/libs/ACE_wrappers/objdir/examples/IPC_SAP/SSL_SAP/http://www.cnblogs.com/http://www.cnblogs.com/ace/SSL/SSL_SOCK_Stream.inl:148: undefined reference to `SSL_read'
/home/knight/libs/ACE_wrappers/objdir/examples/IPC_SAP/SSL_SAP/http://www.cnblogs.com/http://www.cnblogs.com/ace/SSL/SSL_SOCK_Stream.inl:151: undefined reference to `SSL_get_error'
client-SSL-client.o: In function `ACE_SSL_SOCK_Stream::close()':
/home/knight/libs/ACE_wrappers/objdir/examples/IPC_SAP/SSL_SAP/http://www.cnblogs.com/http://www.cnblogs.com/ace/SSL/SSL_SOCK_Stream.inl:305: undefined reference to `SSL_shutdown'
原因:在编译${ACE_ROOT}/objdir/tests/SSL和${ACE_ROOT}/examples/IPC_SAP/SSL_SAP中makefile指定的库路径LIBS指定有误;
解决:找到makefile里的LIBS = -lrt -ldl,在后面添加路径【 /usr/local/ssl/lib/libssl.a /usr/local/ssl/lib/libcrypto.a】(注意,这两个静态库路径不是绝对的)。
安装完成
make install 成功后会有如下显示:
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
默认的安装路径是在/usr/local/lib;
如果程序运行需要动态库.so文件时,需要指定环境变量LD_LIBRARY_PATH;
如果程序连接编译需要动态库.so文件时,需要指定环境变量LD_RUN_PATH。
