c++ - AIX 上 proftpd 的静态编译

我想在 AIX 上编译 proftpd 以使其可部署在其他服务器上，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"

就像 proftpd 官方文档中的建议一样。
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:我已经尝试过 -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 以在其中添加一个文件夹，我将把所有的 lib 打包为一个 tar 文件，并使用里面的 lib 部署 proftpd 安装文件夹，它不干净但它确实有效:

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

我不验证我的答案，因为它不是真正的答案，但可以帮助你们中的一些人。

PS:请考虑到这适用于 IBM XL C Compiler 并且也适用于 GCC

最佳答案

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 选项已成功将选项传递给 ld，但 ld 无法识别该选项。当您使用 AIX ld 时，它需要将 -dn 与 -bsvr4 与链接行一起使用，因此，例如 flags 选项应读取 -Wl,-bsvr4 -Wl,-dn 。

AIX 上的 ld 手册页末尾有一条注释，其中指出:



根据proftpd最终链接行的复杂程度，可以使用-bstatic和-bdynamic选项来提示特定项的静态库加载；所以就我而言，我的最终链接行如下所示:

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，它不是默认提供的库，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。

但是，一般而言，如果您要构建以在另一个系统上部署，我建议您创建您正在使用的依赖库的仅静态拷贝，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。
