Question

我想在AIX上编译proftpd，使其可以在其他服务器上部署，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，但我无法通过选项

进行编译

 LDFLAG="-Wl,-static"

喜欢官方proftpd文档中的建议这里是我得到的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标志但是它们会被忽略。

可能的答案

对我来说，部分解决方案是在libpath中添加一个文件夹到这里我将把所有的lib作为tar文件打包并用lib里面部署proftpd安装文件夹，它不干净但它确实有效：

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

我没有验证我的答案，因为这不是真正的答案，但这可以帮助你们中的一些人。

PS：请注意这与IBM XL C编译器一起使用，并且也适用于GCC

Answer 1

configure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

这表示-Wl选项成功将选项传递给ld，但ld无法识别该选项。当您使用AIX ld时，它需要使用-dn和-bsvr4以及链接行，因此，例如flags选项应为-Wl,-bsvr4 -Wl,-dn。

AIX上ld的手册页末尾有一条注释说明：

只要安装了操作系统的更新版本，就必须再次链接应用程序。静态链接的任何应用程序都不能从任何修订或发布级别二进制移植到任何其他修订或发布级别。

根据proftpd最终链接行的复杂性，您可以使用选项-bstatic和-bdynamic来提示加载特定项目的静态库;所以在我的情况下，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，这不是默认的附带库，所以我重新调整链接行，使其包含-lcrypt：

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

现在它与crypt库的静态版本链接，不再提及它作为运行时链接依赖项的一部分。

作为对此的补充，您应该只在相关操作系统上静态链接默认情况下未提供的库，并且我注意到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，一般情况下，如果您要构建在另一个系统上进行部署，我建议您创建您正在使用的依赖库的静态副本，并将它们显式传递给configure选项。这可以使构建环境在运行时环境中保持干净。

Answer 2

你能尝试只使用“-static”代替“-Wl，-static”吗？
