链接 OpenSSL 时未定义对 t1sl_steup_key_block 的引用 [英] Undefined reference to t1sl_steup_key_block when linking OpenSSL

问题描述

我在将 OpenSSL 库链接到现有项目时遇到问题.我哪里弄错了?

I got a problem of linking an OpenSSL library into an existing project. Where I do get it wrong?

以下是我遵循的步骤.

我已经下载、配置并安装了 SSL 库.它安装在 /usr/local/ssl 中.

I have downloaded the SSL library, configured and installed it. It gets installed in /usr/local/ssl.

2) 我已经将 libcrypto.a 和 libssl.a 从 /usr/local/ssl/lib 复制到我的项目中，有些东西比如/mnt/linux/bla/bla/lib.

2) I have copied libcrypto.a and libssl.a from /usr/local/ssl/lib into my project, something like /mnt/linux/bla/bla/lib.

3) 然后我编辑 make 文件并在那里添加 libssl libcrpto 的路径.添加的路径是项目中的路径，如 /mnt/linux/bla/bla

3) Then I edit the make file and added path of libssl libcrpto there. The path added is one that is in project like /mnt/linux/bla /bla

3) 制作

4) 通过 slick edit 构建项目

4) build project via slick edit

当它构建时，我得到一个很长的错误链，比如

When it builds I get a long error chain, like

../lib/libssl.a(t1_enc.o) :In function 't1sl_steup_key_block: undefined ref

现在，我想将 .a 文件复制到项目中可能会出现问题.有没有其他替代方法，或者我应该使用 ln -s 将 .a 文件从 /usr/local/openssl/lib 链接到我的项目库文件夹中吗?以下是错误.

Now, I guess copying .a files into project could be problem. Is there is any alternative for that or should I use ln -s to link .a files form /usr/local/openssl/lib into my project library folder? Below is the error.

推荐答案

您是否尝试过使用已安装在/usr/lib 目录中的 libssl 和 libcrypto(假设您已经为两者安装了开发包)?一旦使用默认安装编译和运行没有错误，您就可以从源代码构建新的 libssl/libcrypto(?)，安装到 usr/local，然后使用库的 usr/local 版本重建.

Have you tried using the libssl and libcrypto already installed in your /usr/lib directory (assuming you've installed the dev packages for both)? Once that compiles and runs without error using the default install, you can build your new libssl/libcrypto(?) from source, install to usr/local, and rebuild using the usr/local versions of the libraries.
