Linux/X11
Hi all,
I built Qt 5.11 for linux statically with:
configure -static -release -openssl-linked -no-xcb -nomake tests -nomake examples -skip qtwebengine -prefix /opt/qt5111-static -no-opengl
It built without problem and I can build my app using the static Qt but I have problems when the application try to connect to remote server using:
QTcpSocket::connectToHost()
the application crashes while it works fine using dynamic Qt link version.
It only crash if I connect to a server using a name while using an IP it works fine.
Running the app with gdb I get:
[2018-07-17 17:19:11] Debug: QAbstractSocket::HostLookupState [New Thread 0x7ffff6d65700 (LWP 11891)] Thread 3 "Thread (pooled)" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7ffff6d65700 (LWP 11891)] 0x00007ffff79925e8 in _GI__inet_aton (cp=0x7ffff6d62717 "\n", cp@entry=0x7ffff6d6270b "172.28.172.1\n", addr=addr@entry=0x7ffff6d626e4) at inet_addr.c:158 158 inet_addr.c: No such file or directory.
It seems static Qt version doesn't link correctly some network system library.
EDIT:
It seems dlopen is the problem, look at this comment
