libcurl和libssh2-链接时可用的一个或多个lib在运行时不可用 [英] libcurl with libssh2 - one or more libs available at link-time are not available run-time

问题描述

尝试./configure libcurl 7.22.0时出现以下错误

I get the following error when trying to ./configure libcurl 7.22.0

在链接时可用的一个或多个库在运行时不可用.链接时使用的库:-lssh2 -lssl -lcrypto -lrt -lz

one or more libs available at link-time are not available run-time. Libs used at link-time: -lssh2 -lssl -lcrypto -lrt -lz

当我使用-/-with--with-with-libssh2 进行配置时，它就可以正常工作.

When I ./configure with --without-libssh2 it works just fine.

我已采取的步骤:

apt-get install libssl-dev
apt-get install libssh-dev

cd /var
wget http://www.libssh2.org/download/libssh2-1.3.0.tar.gz
tar -zxvf libssh2-1.3.0.tar.gz
cd libssh2-1.3.0
./configure
make
make install

顺便说一句，

SSL支持工作正常.我一定对libssh做错了事

SSL support works fine, by the way. I must have done something wrong with libssh

我也尝试过:

./configure --with-libssh2
./configure --with-libssh2-path=/usr/local/lib
./configure --with-libssh2=/usr
./configure --with-libssh2=/usr/local/lib

但这并没有改变.我不知道还能尝试什么.

But it didn't make a difference. I don't know what else to try.

推荐答案

"libssh-dev"软件包是完全无关且不必要的，因为它是libcurl或libssh2都不使用的另一个库.

The "libssh-dev" package is completely unrelated and unnecessary since it's a different library not used by libcurl nor libssh2.

您面临的问题可能是libssh2的"make install"默认情况下会安装库/usr/local/lib，而您尚未编辑/etc/ld.so.conf来从该目录加载lib.编辑文件并运行ldconfig(两个操作均作为root用户).或者，将libssh2安装到ld.so已搜索到的另一个目录中.

The problem you face is probably that "make install" with libssh2 installs the library /usr/local/lib by default and you have not edited /etc/ld.so.conf to load libs from that directory. Edit the file and run ldconfig (both actions as root). Alternatively, install libssh2 into another directory that already is searched in by ld.so.
