尝试在Linux上进行小型QT程序时。我收到警告为
/usr/bin/ld: warning: libssl.so.10, needed by /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libQt5Network.so, may conflict with libssl.so.1.0.0
/usr/bin/ld: warning: libcrypto.so.10, needed by /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libQt5Network.so, may conflict with libcrypto.so.1.0.0
如何解决冲突？
基本上是路径上方
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/
=
/usr/lib64
我有Centos 7 x64

进行一些测试后，我注意到MyProgram使用了来自两个不同位置的库。
1来自
/usr/lib64
2来自
/opt/openssl-1.0.2l/
所以在myprogram.pro文件中，我删除了第二库包含和从标题文件中删除。
然后我做
qmake-qt5
make
一切都很好，没有矛盾的库。
