What Linux libs needed for connectToHost() to work?

[wysota]

Qt on Linux uses BSD sockets for networking and AFAIK this is part of glibc thus you don't need any extra libraries. Did you verify using system tools (e.g. wireshark) there is no network traffic between the target and its environment?


This is the list of libraries my QtNetwork links against:
$ ldd ~/Qt/5.3/gcc_64/lib/libQt5Network.so | awk '{ print $1; }'
linux-vdso.so.1
libQt5Core.so.5
libpthread.so.0
libstdc++.so.6
libc.so.6
libicui18n.so.52
libicuuc.so.52
libdl.so.2
libgthread-2.0.so.0
librt.so.1
libglib-2.0.so.0
libm.so.6
libgcc_s.so.1
/lib64/ld-linux-x86-64.so.2
libicudata.so.52
libpcre.so.3


You can see it is just pthreads, icu and pcre apart the other standard libraries (+dynamically loaded OpenSSL in case of using SSL sockets).
