未定义的引用链接OpenSSL的时候t1sl_steup_key_block [英] Undefined reference to t1sl_steup_key_block when linking OpenSSL

问题描述

我得到了一个OpenSSL库链接到现有项目的问题。
凡我弄错了吗？

下面是我遵循的步骤。

我已经下载了SSL库，配置和安装它。它被安装在的/ usr /本地/ SSL 。

2）我抄 libcrypto.a 和 libssl.a 从的/ usr /本地/ SSL / lib目录到我的项目，像的/ mnt / Linux的/ BLA / BLA / lib目录。

3）然后我的libssl编辑的make文件，并添加路径libcrpto那里。添加的路径是一个是项目如的/ mnt / Linux的/ BLA / BLA

3）使

4）通过光滑的编辑构建项目

当它建立我弄了半天错误链，像

  ../的lib / libssl.a（t1_enc.o）：在函数't1sl_steup_key_block：未定义参考
 

现在，我想.a文件复制到项目可能是问题。是否有任何替代为或者我应该使用 LN -S 链接.a文件形成的/ usr /本地/ OpenSSL的/ lib目录到我的项目库文件夹？下面是错误。

解决方案

您是否尝试过使用已安装在/ usr / lib目录的的libssl和libcrypto（假设你已经安装了开发包两者）？一旦编译和使用默认安装的无错误运行，你可以建立你的libssl新/ libcrypto（？）从源代码，安装到USR /本地，并使用图书馆的USR /本地版本重建。

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

Below are the steps I have followed.

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

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) 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) make

4) build project via slick edit

When it builds I get a long error chain, like

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

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.

解决方案

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.
