I installed the offline installer "Qt 5.8.0 for Linux 64-bit (766 MB)" and also the tar.gz file for Linux and mac users from the following link:
The tar.gz file I downloaded was qt-everywhere-opensource-src-5.8.0.tar
(My system in RHEL 6.6).
I then transferred both the tar.gz file and the installer to my Desktop and I began referring to this link for additional instructions:
On my desktop, I typed these commands:
gunzip qt-everywhere-opensource-src-5.8.0.tar.gz tar xvf qt-everywhere-opensource-src-5.8.0.tar This created the directory qt-everywhere-opensource-src-5.8.0. I then used cd to go inside this directory and I typed ./configure.
Upon this, I was first asked if I wanted the Open-Source edition or the Commercial one and I chose the Open-Source edition. I was then asked if I agreed with the GPL and LGPL licenses and I chose yes again. In the very end I was shown this message:
Qt is now configured for building. Just run 'gmake'. Once everything is built, you must run 'gmake install'. Qt will be installed into /usr/local/Qt-5.8.0 Prior to reconfiguration, make sure you remove any leftovers from the previous build. After reading this, I wrote gmake on the command line. After processing gmake for several hours, I got these erros:
gmake[4]: Entering directory `/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/examples/scxml/trafficlight-widgets-static' /root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/examples/scxml/trafficlight-widgets-static/qscxmlc_wrapper.sh ../trafficlight-common/statemachine.scxml --header statemachine.h --impl ./statemachine.cpp /root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/bin/qscxmlc: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by /root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/bin/qscxmlc) gmake[4]: *** [statemachine.h] Error 1 gmake[4]: Leaving directory `/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/examples/scxml/trafficlight-widgets-static' gmake[3]: *** [sub-trafficlight-widgets-static-make_first] Error 2 gmake[3]: Leaving directory `/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/examples/scxml' gmake[2]: *** [sub-scxml-make_first] Error 2 gmake[2]: Leaving directory `/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/examples' gmake[1]: *** [sub-examples-make_first] Error 2 gmake[1]: Leaving directory `/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml' gmake: *** [module-qtscxml-make_first] Error 2 Why am I getting these errors? What should I do to resolve them?
EDIT:
When I type gcc -v I get the following output:
Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/root/gcc-4.8.2/libexec/gcc/x86_64-unknown-linux-gnu/4.8.2/lto-wrapper Target: x86_64-unknown-linux-gnu Configured with: /root/Downloads/objdir/../gcc-4.8.2/configure --prefix=/root/gcc-4.8.2 --enable-languages=c,c++,fortran,go --disable-multilib Thread model: posix gcc version 4.8.2 (GCC) I read the errors carefully and realized that the root of my errors is this line:
/root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/bin/qscxmlc: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by /root/Desktop/qt-everywhere-opensource-src-5.8.0/qtscxml/bin/qscxmlc) I referred to a Stack Overflow answer and based on that I typed the following command:
strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX and it gave me the following output:
GLIBCXX_3.4 GLIBCXX_3.4.1 GLIBCXX_3.4.2 GLIBCXX_3.4.3 GLIBCXX_3.4.4 GLIBCXX_3.4.5 GLIBCXX_3.4.6 GLIBCXX_3.4.7 GLIBCXX_3.4.8 GLIBCXX_3.4.9 GLIBCXX_3.4.10 GLIBCXX_3.4.11 GLIBCXX_3.4.12 GLIBCXX_3.4.13 GLIBCXX_FORCE_NEW GLIBCXX_DEBUG_MESSAGE_LENGTH So apparently, GLIBCXX_3.4.14 isn't on my system and it is looking for it. How can I get around this problem?
