c++ - AIX 上 proftpd 的静态编译

Question

我想在 AIX 上编译 proftpd 以使其可部署到其他服务器上，而无需在每台服务器上重新安装所有 gnu lib 库。
我已经设法动态编译它，但我无法使用选项编译它

 LDFLAG="-Wl,-static"  

喜欢官方 proftpd 文档中的建议。
这是我得到的 config.log 错误

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.61.  Invocation command line was

  $ ./configure LDFLAGS=-Wl,-static --with-modules=mod_tls:mod_sql:mod_sql_mysql:mod_sql_passwd:mod_sftp:mod_sftp_sql --without-getopt --enable-openssl --with-includes=/opt/freeware/include:/opt/freeware/include/mysql/mysql/:/home/poney2/src_proftpd/libmath_header/ --with-libraries=/opt/freeware/lib:/opt/freeware/lib/mysql/mysql/:/home/poney2/src_proftpd/libmath_lib --prefix=/home/poney/proftpd_bin --exec-prefix=/home/poney/proftpd_bin/proftpd

PS:我已经尝试了 -Bstatic -all-static 和 -static 标志，但它们被忽略了。

可能的答案

对我来说，部分解决方案是修改 libpath 以向其中添加一个文件夹，我将把所有 lib 打包为一个 tar 文件，并部署包含 lib 的 proftpd 安装文件夹，它不干净但它确实有效:

LDFLAGS="-Wl,-blibpath:/a/new/lib/path"

我没有验证我的答案，因为它不是真正的答案，但这可能对你们中的一些人有所帮助。

PS:请注意，这是与 IBM XL C 编译器一起工作的，并且应该也可以在 GCC 上工作

Answer 1

配置脚本的输出显示:

configure:2691: gcc   -Wl,-static conftest.c  >&5
ld: 0706-012 The -t flag is not recognized.
ld: 0706-012 The -a flag is not recognized.
ld: 0706-012 The -t flag is not recognized.
ld: 0706-027 The -i flag is ignored.
ld: 0706-012 The -c flag is not recognized.
collect2: ld returned 255 exit status

这表明 -Wl 选项成功将选项传递给 ld，但 ld 不识别该选项。当您使用 AIX ld 时，它需要使用 -dn 以及 -bsvr4 和链接行，因此，例如标志选项应该是 -Wl ,-bsvr4 -Wl,-dn.

在 AIX 上 ld 的手册页末尾有一条注释指出:

The application can also have to be linked again whenever an updated release of the operating system is installed. Any application that is statically linked is not binary portable from any fix or release level to any other fix or release level.

根据proftpd最终链接行的复杂程度，可以使用选项-bstatic和-bdynamic来提示加载特定项的静态库；所以在我的例子中，我的最终链接行看起来像:

gcc -o proftpd <lots of .o files> -L/home/user/Development/experiments/proftpd-1.3.4d/lib -lsupp -lcrypt -ldl -L/home/user/Development/experiments/proftpd-1.3.4d/lib/libcap -lcap -lpam

现在在这种情况下，这意味着它依赖于 libcrypt，它不是默认附带的库，所以我重新调整链接行，使其包含 -lcrypt 包装:

-Wl,-bstatic -lcrypt -Wl,-bdynamic

现在它与 crypt 库的静态版本链接，并且不再将其作为运行时链接依赖项的一部分提及。

作为对此的补充，您应该只静态链接相关操作系统默认未提供的库，我注意到 proftpd 支持动态加载模块，这意味着您应该只静态链接所需的模块.

不过，一般来说，如果您要在另一个系统上进行部署，我建议您为正在使用的依赖库创建静态拷贝，并将它们显式传递到配置选项中。这使构建环境与运行时环境保持清洁。
