当我试图加载cer文件时,QSslCertificate崩溃了
QSslCertificate crashes when i try to load a cer file
我在Qt中有这个代码
QFile file(address);
file.open(QIODevice::ReadOnly);
const QByteArray bytes = file.readAll();
qDebug()<<"Length : " + QString::number(bytes.length());
const QSslCertificate cert(bytes,QSsl::Der);
当我在windows 7 64位中尝试这段代码时,它工作得很好,但是当我为linux编译它时,它每次到达最后一行时都会崩溃,即使它给了我正确的长度,但它在终端中崩溃了。

我没有在我的代码中使用任何QSslSocket,我现在被困在这个问题上好几天了。
qt 5.4.2版本在Ubuntu 13.10 64位和CentOS 6.4 64位测试
我在Windows和Linux上都使用了openssl-1.0.2d
我找到了一个解决方案,我所做的是:
OpenSSL 1.1.0与QT不兼容,所以我克隆了1.0.1的稳定版本:下面是bug: https://bugreports.qt.io/browse/QTBUG-52905git clone https://github.com/openssl/openssl -b OpenSSL_1_0_1-stable
然后安装到自定义位置:
./config --prefix=/opt/openssl-stable
make
make test
sudo make install
获取QT源代码,然后当你想要构建它们时,你必须链接已安装的OpenSSL:
OPENSSL_LIBS='-L/opt/ssl/lib -lssl -lcrypto' ./configure -openssl-linked
见:http://doc.qt.io/qt-5/ssl.html
这是我的配置:
OPENSSL_LIBS='-L/opt/openssl-stable/lib -lssl -lcrypto' ./configure -prefix /opt/qt5.7_linux_staticssl -opensource -confirm-license -release -openssl-linked -I /opt/openssl-stable/include/openssl -L /opt/openssl-stable/lib
,如果qt构建给你一个错误,它没有找到一些SSL结构,只是复制/opt/openssl-stable/include/openssl头到/usr/include/openssl或qt正在寻找他们的地方(你可以看到,当qt构建失败时)
就这样了
