How to build and install dpdk v.18.08 on Centos 7.6 with gcc? - dpdk

I am trying to build and install dpdk v.18.08 on Centos 7.6 with gcc 4.8.5.
This is what I have done:
$ tar xvfz /opt/dpdk/dpdk-18.08/tar.gz
$ cd /opt/dpdk/dpdk-18.08
$ make -j T=x86_64-native-linuxapp-gcc install
<snip>
Build complete [x86_64-native-linuxapp-gcc]
Installation cannot run with T defined and DESTDIR undefined
How can I fix this failure to install?

If you want a specific folder to house current binaries and library, 'make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc'.
This will create a folder 'x86_64-native-linuxapp-gcc'. You have set RTE_TARGET as x86_64-native-linuxapp-gcc. Then build by 'cd x86_64-native-linuxapp-gcc; make -j 10'
Edit: O in 'make config' is the target folder.

Qt 6.2.4 for QNX710 on Ubuntu 20.04 - Qt version is not properly installed

I tried to build Qt 6.2.4, installed via qt-unified-linux-x64-4.3.0-1-online.run on Ubuntu 20.04 LTS in a Virtual Box.
I installed Qt 6.2.4 in ~/Qt6 for Desktop gcc 64-bit and in source code.
QNX 7.1 is installed in ~/qnx710.
I sourced qnxsdp-env.sh:
$ . ~/qnx710/qnxsdp-env.sh
I added Qt6.2.4, Ninja and CMake to PATH:
$ export PATH=$PATH:~/Qt6/6.2.4/gcc_64/bin
$ export PATH=$PATH:~/Qt6/Tools/Ninja
$ export PATH=$PATH:~/Qt6/Tools/CMake/bin
Copied the qnx.cmake example from https://doc.qt.io/qt-6/building-qt-for-qnx.html#creating-a-toolchain-file-for-qnx
$ cat ~/cmake_support/toolchains/qnx.aarch64le.cmake
set(CMAKE_SYSTEM_NAME QNX)
set(arch gcc_ntoaarch64le)
set(CMAKE_C_COMPILER qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER q++)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
set(CMAKE_SYSROOT $ENV{QNX_TARGET})
Created a build directory and configured qt:
$ mkdir ~/Qt6/6.2.4/qnx_build
$ cd ~/Qt6/6.2.4/qnx_build
$ cmake -GNinja -DCMAKE_TOOLCHAIN_FILE=~/cmake_support/toolchains/qnx.aarch64le.cmake -DQT_HOST_PATH=~/Qt6/6.2.4/gcc_64 -DCMAKE_INSTALL_PREFIX=~/Qt6/6.2.4/qnx ../Src
Compile and install
$ cmake --build . --parallel && cmake --install .
This all went fine.
Then I tried to add the new Qt Version to Qt Creator, but this fails with Qt version is not properly installed, please run make install.
Details: Invalid Qt version.
And of course, once creating a kit, it fails and can't be used.
Any idea how to fix this?
The Qt version was indeed not properly installed.
qmake expects a specific directory for target libraries
$ ~/Qt6/6.2.4/qnx/bin/qmake -v
QMake version 3.1
Using Qt version 6.2.4 in /home/werner/qnx710/target/qnx7/home/werner/Qt6/6.2.4/qnx/lib
So to fix QT Creator, I simply had to create a symbolic link:
$ cd ~/qnx710/target/qnx7
$ mkdir -p home/werner
$ ln -s ~/Qt6 .

Cannot install MySQL connector/c++ correctly in my ubuntu

I followed the instructions given by Mysql but I got an error when I want to test it.
These are my inputs:
$ git clone https://github.com/mysql/mysql-connector-cpp.git
$ cd mysql-connector-cpp
$ git checkout 8.0
$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .
$ sudo cmake --build . --target install
$ cmake -DWITH_CONCPP=/usr/local/mysql/connector-c++-8.0 ../testapp
And I got an error:
Using dynamic runtime library.
Generationg 64bit code
Looking for connector libraries here: /usr/local/mysql/connector-c++-8.0/lib64
Looking for the main library mysqlcppconn8
CMake Error at CMakeLists.txt:165 (message):
Could not find MySQL Connector/C++ 8.0 library mysqlcppconn8 at specified
location: /usr/local/mysql/connector-c++-8.0/lib64
-- Configuring incomplete, errors occurred!
And here is the document link:
MySql Installing Connector/C++ from Source
This is the relevant part of the document.
To verify connector functionality, build and run one or more of the test programs included in the testapp directory of the source distribution. Create a directory to use and change location into it. Then issue the following commands:
$ cmake [other_options] -DWITH_CONCPP=concpp_install concpp_source/testapp
other_options consists of the options that you used to configure
Connector/C++ itself (-G, WITH_BOOST, BUILD_STATIC, and so forth).
concpp_source is the directory containing the Connector/C++ source
code, and concpp_install is the directory where Connector/C++ is
installed:
I also occured your problems. This is my solution:
$ git clone https://github.com/mysql/mysql-connector-cpp.git
$ cd mysql-connector-cpp
$ git checkout 8.0
$ mkdir build
$ cd build
# The problem is here: CMAKE_BUILD_TYPE default value is Debug
# so it install .so in WITH_CONCPP/lib64/debug.
$ cmake -DCMAKE_BUILD_TYPE=Release ..
# I don't know why the options "--config Debug( or Release)" is disable.
$ cmake --build .
$ sudo cmake --build . --target install
$ cmake -DWITH_CONCPP=/usr/local/mysql/connector-c++-8.0 ../testapp

How to Install Wt into a Custom Folder Without "fatal error: Wt/WApplication: No such file or directory"

I'm new to Wt and c++ and I just installed the Wt webframework on Ubuntu 16.04 LTS into a custom folder in my home directory. I cannot install or build any software into the /usr diretories of this computer. Even if I could, the PPA hasn't been active for 2 1/2 years, and the official Ubuntu installation instructions are also outdated. Aptitude no longer ships with Ubuntu and will eventually be discontinued.
I compliled and installed everything successfully, yet when I try to compile the Hello World example I get the following error:
g++ -o hello hello.cpp -lwt -lwthttp
fatal error: Wt/WApplication: No such file or directory
Here are my installation steps:
Boost:
wget https://dl.bintray.com/boostorg/release/1.65.1/source/boost_1_65_1.tar.bz2
tar --bzip2 -xf boost_1_65_1.tar.bz2
cd boost_1_65_1
./bootstrap.sh --prefix=../myfolder
sudo ./b2 install --prefix=../myfolder
CMake:
wget https://cmake.org/files/v3.9/cmake-3.9.2.tar.gz
tar -xvzf cmake-3.9.2.tar.gz
cd cmake-3.9.2
./configure --prefix=../myfolder
make
sudo make install
vim .profile
export PATH=$PATH:/home/ubuntu/myfolder/bin
Wt:
git clone https://github.com/emweb/wt.git
cd wt
cmake -DCMAKE_INSTALL_PREFIX:PATH=../myfolder .
-- Generating done
-- Build files have been written to: /home/ubuntu/myfolder
make
sudo make install
make -C examples
Since I'm lumping everything together in /myfolder I did not use the /build folder per the Wt installation instructions. The libwt and libboost libraries are in /myfolder/lib. I assumed all of the linking was taken care of during installation.
Any thoughts? Thanks in advance.
You have to tell your compiler to look for includes and libraries in the right folders, so instead of:
g++ -o hello hello.cpp -lwt -lwthttp
Try:
g++ -o hello hello.cpp -I/home/ubuntu/myfolder/include -L/home/ubuntu/myfolder/lib -lwt -lwthttp
Note that when you run your application, you'll also have to make sure that it can find the dynamic libs (.so files) it needs. You could do this:
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/ubuntu/myfolder/lib"

my problem is resolved after installing qt5-default:
sudo apt-get install qt5-default
Thanks
From the updated question it is clear that
/usr/bin/qmake is a soft link to qtchooser
The error message with the qtchooser is normal, although uninformative. In essence you're trying to execute qtchooser with itself, which doesn't work.
Run the $ man qtchooser command on a terminal for how to use qtchooser
If you are not able to see the man page for qtchooser or if the problem persists then I suggest you to install
$ sudo apt-get install qt-sdk
Hope this would solve your problem
Try to set the qmake path to /usr/lib/i386-linux-gnu/qt5/bin/qmake. This is where qt5-qmake installs its qmake executable.

library not found for -lgomp [duplicate]

I'm trying to get openmp to run in my program on Mavericks, however when I try to compile using the flag -fopenmp I get the following error:
ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The command I am running is:
gcc myProgram.cpp -fopenmp -o myProgram
Also, when I run gcc I get Clang warnings which I find to be very strange. And looking into /usr/bin/gcc it does not appear to link to Clang.
Any suggestions on how to fix my Clang errors and get openmp to compile?
The gcc command in the latest Xcode suite is no longer the GCC frontend to LLVM (based on the very old GCC 4.2.1) but rather a symlink to clang. Clang does not (yet) support OpenMP. You have to install separately another version of GCC, e.g. by following this tutorial or by using any of the available software package management systems like MacPorts and Homebrew.
I just recently attacked this problem and have scripted the process of getting everything working based on the official instructions.
The script will download everything into ~/code for easy maintenance and will append the correct environment variables to your ~/.profile file. For advanced users, pick a nice location you want the lib, bin and include installed and move them manually. The script depends on knowing the latest OpenMP runtime from Intel, which can be altered at the top of the script.
The script should work out of the box with vanilla Mavericks, except for one small problem. In the OpenML runtime make script, it does not reliably accept clang when specified and continues with the default GCC. As such, if you don't have GCC installed (which is not normal on out of the box Mavericks), it will fail to build. To fix this, you must comment out two lines (as noted in the script) based on the libomp_20131209_oss.tgz build of OpenMP. Newer builds of OpenML might break this script, so use at your own peril on newer versions.
Simply save this script into a file, run 'chmod +x filename.sh', and run './filename.sh' from terminal. It will take a while to build LLVM and Clang, so be patient.
EDIT: This script will most likely fail on Yosemite and I am having issues using the built clang2 after the update to the dev builds of OSX 10.10.

If you are running homebrew you can fix this problem by calling:
brew install clang-omp
The compiler will be available under clang-omp++ name
Just worked through this problem. Here's the answer plus how to get it worked with Xcode.
Grab the latest version of openMP runtime library from
https://www.openmprtl.org/download
unzip and compile it by
mkdir build && cd build && cmake .. && make && sudo make install
install it by
sudo cp ./libiomp5.dylib /usr/lib/
sudo cp ./omp.h /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/
Grab openmp/clang from Git following the instructions on http://clang-omp.github.io/
compile openmp/clang
cd llvm && mkdir build && cd build && ../configure --enable-optimized && make -j
sudo make install
normally it would install clang/clang++ into /usr/local/bin, we need replace the Apple clang with our version
cd /usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
sudo mv -f * ../../
Create a project in Xcode, using the Hello World code on clang-openmp website for test. After created, add "-fopenmp" to Custom Compiler Flags -> Other C Flags in project settings; add /usr/lib/libiomp5.dylib to the build phases of project (project settings -> Build Phases -> Drag /usr/lib/libiomp5.dylib into Link Binary with Libraries)
It should work. Yosemite + Xcode 6 is tested.
Note: the custom clang is NOT as stable as Apple's. Switch back if you meet strange instruction error after compiled.
