[提问]qt调用libssh2编译报错 [复制链接]

更正一下，之前的pro文件的路径有问题
这是linux下的，报错只截取了开头的部分：
问题：
/usr/local/lib64/libssh2.a(channel.o):-1: In function `channel_x11_req':
/home/phoenix/libssh2-1.4.3/src/channel.c:1138: error: undefined reference to `RAND_bytes'
window.open('http://www.qtcn.org/bbs/attachment/Mon_1503/17_140319_c94a40cc8731732.jpg?24');" style="max-width:700px;max-height:700px;" onload="if(is_ie6&&this.offsetWidth>700)this.width=700;" >

为什么会提示找不到文件，可是路径明明没错啊

phoenix@phoenix  :~/libssh2-1.4.3> ll /usr/local/lib64/libssh2.a
-rw-r--r-- 1 root root 1502520 3月   2 05:15 /usr/local/lib64/libssh2.a

我一般添加库的时候都是用LIBS += -LXXX/XX/XX -lXXX，让他在指定的目录自动去搜索指定的库

自己顶顶

重新把问题描述了一下，谁给看看是怎么回事儿啊谢谢。

回2楼，的确是这样的，可是为什么我已经定义了LIBS += /usr/local/lib64/libssh2.a，它却要到/home/phoenix/qt_project/ssh/libssh2/lib/这下面去找libssh2.a呢？

你说那个rtc开关要关掉，你如果用的是vc编译器就按照vc的来做就是了，关qt啥事，估计是改改define或者cflag之类的吧

/home/phoenix/qt_project/ssh/libssh2/lib/libssh2.a
和
LIBS += /usr/local/lib64/libssh2.a

不是一个路径啊！
