I want to setup connector/c++ on my raspberry Pi to access a mysql db. At first I tried:
sudo apt-get install libmysqlcppconn-dev
which installed successfully, but the I got the error:
ERR: MySQL_Connection::setReadOnly() (MySQL error code: 0, SQLState: )
which comes with the version of cppconn I'm using, as its said here: MySQL Connector for C++ | MySQL_Connection::setReadOnly() exception on setSchema
And when I checked:
sudo apt-cache show libmysqlcppconn-dev
it said "version: 1.1.0-4"
So then I tried to install the latest package from source:
https://dev.mysql.com/downloads/connector/cpp/ which was under ->Source Code -> Generic Linux (Architecture Independent), Compressed TAR Archive
I downloaded it and did "tar xvzf mysql-...." and everything worked. But when I tried to build it with
cmake .
I got the error:
CMake Warning (dev) in CMakeLists.txt:

I know it means, it cant find the mysql_config, but neither do I know how to tell it where the file is, nor where the file actually is.
So please help me. I'm so sick of this.
Thanks alot.
EDIT:
I tried to install the latest packages manually, which I downloaded from:
https://packages.debian.org/jessie/armhf/libmysqlcppconn-dev/download
sudo dpkg -i libmysqlcppconn7_1.1.3-6_armhf.deb
sudo dpkg -i libmysqlcppconn-dev_1.1.3-6_armhf.deb
And now I get:

Is this good or bad?
You need to install the MySQL client library development files:
apt-get install libmysqlclient-dev
An easier way to try and ensure you have all dependencies installed, is to ask apt to install all build dependencies for it's packaged version:
apt-get build-dep libmysqlcppconn-dev
The libmysqlclient-dev package doesn't exist anymore. I guess it was renamed. So to install the c++ connector there is this new package:
sudo apt install libmysql++-dev

Please help me.
to install xhtml2pdf in python 3.11
If go to github and look at about libxml2
https://github.com/GNOME/libxml2
you can find manual how to build it.
CMake (mainly for Windows)
Another option for compiling libxml is using CMake:
cmake -E tar xf libxml2-xxx.tar.gz
cmake -S libxml2-xxx -B libxml2-xxx-build [possible options]
cmake --build libxml2-xxx-build
cmake --install libxml2-xxx-build

I having trouble integrating vcpkg package manager with CMake project on Linux. I want to use the doctest library in my project but the same problem exists with other packages too. I performed the following steps.
$ vcpkg install doctest
Computing installation plan...
The following packages will be built and installed:
doctest[core]:x64-linux -> 2.4.9

doctest provides CMake targets:

find_package(doctest CONFIG REQUIRED)
target_link_libraries(main PRIVATE doctest::doctest)
$ vcpkg integrate install
Applied user-wide integration for this vcpkg root.
CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=/home/bobeff/projects/cpp/vcpkg/scripts/buildsystems/vcpkg.cmake"
I have a vcpkg.json file in the root directory of my project with the following content:
{
"name": "cpp-programming-language",
"version-string": "0.1.0",
"dependencies": [
"doctest"
]
}
$ cmake ../cpp_programming_language/ -DCMAKE_TOOLCHAIN_FILE=/home/bobeff/projects/cpp/vcpkg/scripts/buildsystems/vcpkg.cmake
The last command is giving me the following output:
CMake Error at CMakeLists.txt:7 (find_package):
Could not find a package configuration file provided by "doctest" with any
of the following names:

Add the installation prefix of "doctest" to CMAKE_PREFIX_PATH or set

"doctest" provides a separate development package or SDK, be sure it has
been installed.

I have not been able to install either llvm version 9 or clang version 9 on Ubuntu. We have installed them on Windows.
I have tried a command and saw this response.
sudo apt-get install llvm-9
Reading package lists... Done

Done E: Unable to locate package llvm-9
I have also tried and saw this response.
sudo apt-get install clang-9

My /etc/apt/sources.list file contains
deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-9.0 main
I found the website and saw that the folder was llvm-toolchain-xenial-9. Trying that version did not work either.
What else can I do?
I have looked at downloading the binaries but am not sure what installation steps I might be missing. I am not interested in compiling source code.
The Clang/LLVM project provides Nightly build packages for Ubuntu and Debian.
See the https://apt.llvm.org
The goal is to provide Debian and Ubuntu [Clang and LLVM] packages ready to be installed with minimal impact on the distribution.
Packages are available for amd64 and i386 (except for recent Ubuntu) and for both the stable, old-stable and development branches (currently 8, 9 and 10).
Packages are built using stage2 and extremely similar to the one shipping in Debian & Ubuntu.
To use:
Add the appropriate repositories to the /etc/apt/sources.list file; there are distinct repos for different Debian and Ubuntu versions.
Add the apt key (shown in the link).
Run an apt update to refresh the cache.
Add packages with apt install clang-9 (or other package as desired).
If something "did not work" using the vetted package system, diagnose that issue directly. Xenial has Clang/LLVM 9 packages, and I've recently installed the packages into Disco.
The described symptom ("Unable to locate package") sounds as though one neglected to run apt update, in which case the packages from the newly-added sources would not be visible to apt. This is a tool-usage issue, not a lack of available packages.

I am really new to programming and Linux and I want to install PCL.
Now I want to install VTK and Qt 5.6. So I followed the steps on this site:
http://www.vtk.org/Wiki/VTK/Building/Linux
When I want to configure VTK I get this error:

Add the installation prefix of "Qt5UiPlugin" to CMAKE_PREFIX_PATH or set
"Qt5UiPlugin_DIR" to a directory containing one of the above files. If
"Qt5UiPlugin" provides a separate development package or SDK, be sure it

How can I recompile a programm? Can somebody help? I am really frustrated...
Thanks!!
What distro are you using? If you're on ubuntu you should try this:
sudo apt-get install qttools5-dev
sudo apt-get update
Hope that helps.
After downloading and untar the file "boost_1_56_0.tar.gz", I have installed Boost C++ library version "boost_1_56_0" in CentOS Linux.
I have run the following commands to install:
sudo ./bootstrap.sh --prefix=/usr/local
sudo ./b2 install.
I also added two paths to the PATH variable:
export PATH=$PATH:/usr/local/include/:/usr/local/lib/
It has been successfully installed. However when I checked the version it showed different version:
$ cat /usr/include/boost/version.hpp | grep "BOOST_LIB_VERSION"
#define BOOST_LIB_VERSION "1_33_1"
I have tried to install boost_1_55_0 as well in another folder but unfortunately still it shows version 1_33_1.
Can anyone here tell me how I can fix this issue?
Because of this issue, I am unable to configure Graph_tool; it shows following error:
checking for boostlib >= 1.53.0... configure: error: We could not detect the boost libraries (version 1.53 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in . See http://randspringer.de/boost for more documentation>
Your bootstrap path is /usr/local. Make sure your BOOST_ROOT points to your bootstrapped folder, not the installed 1.33 version.
