Can someone explain what is a correct way to include some modules and addons while doing ./configure in Qt5.5.1?
I should have a x11 addon installed and tried that with:
./configure -qt-x11
./configure -qt-x11extrass
but it doesn't work.
I am reading this for configure options, but I figured out that many things you have to guess how they need to be done. I am building qt5.5.1 on Ubuntu 14.04.3 to cross-compile for BBB.
If you want to build some module (all module dependency packages must be installed first), you need to go to module directory (for example qtmultimedia in qt directory) and run qmake (built for your specific architecture), after that make and sudo make install. Now you will be able to include required module into your .pro file.

Just tried Vcpkg Manifest on my cmake project and it is cool, with exceptions however.
My project depends on opencv and it takes a long time for vcpkg to install opencv. So I realized I don't want vcpkg downloawding/installing opencv every time I clone the project in a different folder.
Is it possible to use Vcpkg Manifest but make it install libraries system wide instead of locally to the project?
Or at least not inside the build directory, so will be possible to reuse it?
No, you can't install libraries system-wide in manifest mode.
But binaries are cached so that if you use a library in multiple projects, you don't have to build it from scratch.
https://github.com/microsoft/vcpkg/blob/master/docs/users/binarycaching.md
I abused vcpkg's --x-install-root to achieve similar results as manifest mode.
--x-install-root= (Experimental) Specify the install root directory
Under your project folder, you can install this project's dependencies into a system global directory by using this parameter, so that all projects can share the installed packages system wide. For example, in my case, I installed all packages into $VCPKG_ROOT/installed directory like this:
vcpkg install --x-install-root=$VCPKG_ROOT/installed
You can even use vcpkg list anywhere if you (ab)use it this way.
My project has a dependency on native curl (library, header, etc.)
On Ubuntu, I apt-installed libcurl4-gnutls-dev, which brought everything I needed to my /usr/lib and /usr/include directories. Moreover, I don't know how, but some how, in my cmake build, I also have find_package(CURL) working just fine.
I now need to port my project to Yocto (Cisco IR1101 router). Installing with opkg libcurl4 works just fine, but it only brings the *.so files. curl.h is (rightfully) missing.
I cannot find any development package, or the form libcurl-dev, libcurl4-dev, libcurl4-gnutls-dev, etc.
Alternatively, I tried to build the sources (github/curl/curl - appears to be a cmake project), but asking me openssl and other dependencies not available on my machine.
I have compiled QT-5.8 from github successfully, each submodule is cloned by init-repository provided by QT. However, in Qt5.8, it has removed qtwebkit.
But my app needs qtwebkit, so I clone qtwebkit submodule and qmake it.
However, it shows the compilation errors
( test -e Makefile.api || /usr/local/Qt-5.8.0/bin/qmake -o Makefile.api /home/tumh/qt5/qtwebkit/Source/api.pri ) && make -f Makefile.api
make[1]: Entering directory '/home/tumh/qt5/qtwebkit/Source'
make[1]: *** No rule to make target '/home/tumh/qt5/qtwebkit/Source/WebCore//libWebCore.a', needed by '../lib/libQt5WebKit.so.5.8.0'. Stop.
make[1]: Leaving directory '/home/tumh/qt5/qtwebkit/Source'
Makefile:40: recipe for target 'sub-api-pri-make_first-ordered' failed
make: *** [sub-api-pri-make_first-ordered] Error 2
I have no idea that how to compile a single submodule in QT.
Any suggestion is appreciated.
thanks!
You should take tarball of webkit from official releases. It should build fine with Qt-5.8.
The following describes how to compile qtwebkit module so it is usable with Qt 5.9.9. I assume the process is similar if not identical for Qt 5.8.
An overview of the process
All of the required components should be compiled using one tool chain. I suggest using the one installed with Qt.
You gonna need ICU compiled, the source code can be obtained from the official site.
The source code of qtwebkit module that we want to compile is available here (thx #J. Doe for the link!)
Regardless of the operating system you are working on, in order to compile qtwebkit module you gonna need the following additional tools:
ruby
gperf
flex
bison
python 2
Qtwebkit module depends on declarative module. It becomes available when qtquick1 is installed.
It is assumed that Qt 5.9.9 is installed. I was using these installers.
The process takes some time so if you need the module ready ASAP go to the last section (What if you cannot perform some of the above steps).
Compiling on Windows (tested on Win10)
On Windows I recommend using chocolatey to install additional tools.
Compiling ICU
Install msys2 package via chocolatey. It allows to use the scrips provided with ICU source code with very few modifications.
Installation script requires make program available. It doesn't matter if mingw32-make is virtually (of even literally) the same tool. Copy mingw32-make.exe and rename it to make.exe.
Using cmd with integrated mingw tools (installed along with Qt) open msys2 shell forwarding the PATH variable.
msys2_shell -use-full-path
Go to the ICU source code directory (mine was C:\icu\source) and run
./runConfigureICU MinGW -prefix=$PWD/../dist
(It is expected to encounter "unknown platform" issue, no worries)
Now run:
gcc -dumpmachine
Save the output, in my case it was i686-w64-mingw32.
Using this result execute:
./configure -build=i686-w64-mingw32 -prefix=$PWD/../dist
(modify build parameter according to the result of the previous step)
Now, you should be able to compile ICU with:
make & make install
(If you want to speed things up you can engage multiple CPU cores in the above process. For example in order to engage 777 cores execute make -j777 & make install)
Assuming your ICU source code was in C:\icu\source directory, the result of the compilation should be in C:\icu\dist.
Compiling qtwebkit module
As said in the first section, compiling qtwebkit module requires additional tools.
They can be installed via chocolatey using the following command:
choco install ruby gperf winflexbison python2
This, among others, installs win_flex.exe and win_bison.exe. As of this writing these executables are located (at least in my case) in C:\ProgramData\chocolatey\lib\winflexbison\tools .
The qmake checks for programs named bison.exe and flex.exe. So I have copied both win_flex.exe and win_bison.exe and renamed them flex.exe and bison.exe accordingly.
The last step is to add both of these programs to PATH variable.
To do so execute (in cmd with integrated mingw tools) the following command:
set PATH=C:\ProgramData\chocolatey\lib\winflexbison\tools;%PATH%
Additionally you need to point to the directory where includes and libs of compiled ICU are located. I have done it like this:
set PATH=C:\icu\dist\bin;%PATH%
set INCLUDE=C:\icu\dist\include;
set LIB=C:\icu\dist\lib;
Above assumes that prior to executing this commands there was no variables named INCLUDE and LIB set in the currently used cmd.
Finally, qmake process checks for a variable named SQLITE3SRCDIR.
As suggested by this answer you can set it to sqlite sources provided with Qt. In my case it was done like this:
set SQLITE3SRCDIR=C:\Qt\Qt5.9.9\5.9.9\Src\qtbase\src\3rdparty\sqlite
Now (using the same cmd) go to the directory where Qt sources are located and execute configure.bat. I have done both of these steps with:
cd C:\Qt\Qt5.9.9\5.9.9\Src
configure.bat
Finally, extract the downloaded source code of the qtwebkitmodule to the sources directory of Qt (C:\Qt\Qt5.9.9\5.9.9\Src in my case) and make a module. I have done it like this:
cd qtwebkit-opensource-src-5.9.0
mkdir build
cd build
qmake -r ..
make
make install
It is strongly recommended to utilize multiple cores in the make process, otherwise prepare yourself for a very long compilation.
Now you should be able to use webkit and webkitwidgets in your Qt projects.
Compiling on Linux (tested on LUbuntu 18.04)
I suggest using compilation tools provided with Qt instead of default make and g++ compiler. To do so I have exported path to the tools provided with Qt like this:
export PATH=/home/$USER/Qt5.9.9/5.9.9/gcc_64/bin/:$PATH
You gonna need ICU compiled. I suggest using version 56.1 as it is the same shipped with Qt 5.9.9. The compilation process is almost identical as it was described for Windows. the only difference is that you run:
./runConfigureICU Linux/gcc --prefix=$PWD/../dist
and later configure script can be omitted on Linux.
On lUbuntu 18.04 I needed the following packages installed:
apt-get install ruby bison gperf python flex perl libx11-dev xserver-xorg-dev xorg-dev libpulse-dev libsqlite3-dev
As with compiling qtwebkit on Windows, you gonna need qtquick1 module installed.
I have encountered an error saying that some headers related to OpenGL were missing. If you have the same problem then in my case installing libgl1-mesa-dev package solved it.
Now extract source code of qtwebkit module sources directory of your Qt installation. In my case it was "/home/$USER/Qt5.9.9/5.9.9/Src".
Modify WTF.pri file and add the path to ICU includes and libs after the first INCLUDEPATH. In my case it was done like this:
...
INCLUDEPATH += /home/$USER/icu/dist/include/
LIBS += -L/home/$USER/icu/dist/lib/
...
Note '-L' is placed before path pointing to libs.
Now you should be able to compile qtwebkit module in usual manner:
mkdir build
cd build
qmake -r ..
make & make install
What if you cannot perform some of the above steps
You can always try to use prebuild binaries:
https://download.qt.io/snapshots/ci/qtwebkit/5.9/latest/qtwebkit/
or unofficial fork of the qtwebkit module:
https://github.com/qtwebkit/qtwebkit/releases
I am new in Ubuntu/Linux and I've been working with java using the NetBeans IDE, so I don't have much experience with building c++ projects. But now I have to provide a proof of concept and I need to connect a C++ client with my ActiveMQ server. I downloaded The ActiveMQ-CPP API from this link, but I can't build/run it.
The download came with the files: Maklefile.am and Makefile.in. I searched it and I found that I need automake/autoconf to build it. I tried running ./configure but it says that it couldn't find such file or directory. I tried
sudo apt-get update
sudo apt-get install automake
sudo apt-get install autoconf
and a lot of other commands that I found on the Internet. None of then worked. I know that this question is really basic and it seems to be already answered somewhere else, but every attempt I've made failed. I think I'm missing something. I even tried the solution provided in the last message in this topic but it didn't work either.
Can anyone help me install autoconf/automake, or tell me how to use Makefile.am / Makefile.in to build the project I downloaded, or even suggest me some other way of building it?
Since you're open to other methods of building your project, I'm going to suggest CMake. It is a far better build system than autotools (at least from where I stand).
#CMakeLists.txt
project(MyProject CXX)
set_minimum_required(VERSION 2.8)
add_executable(foobar foo.cpp bar.cpp)
That example will build an executable called "foobar" by compiling and linking foo.cpp and bar.cpp. Put the above code in a file called CMakeLists.txt, then run the following commands:
cmake <path to project> #run in the folder you want to build in
make #this does the actual work
The really cool thing about CMake is that it generates a build system (Makefiles by default) but you can use it to generate project files for Eclipse, a Visual Studio solution, and a bunch of other things. If you want more information, I'd check out their documentation.
The "configure" script should be in your ActiveMQ-cpp source directory. From the Linux command line, you should be able to:
1) "cd" into your ActiveMQ* directory
2) "ls -l" to see the "configure" script
3) "./configure" to set things up for building the library\
4) "make" to actually build the library
This is mentioned in comments, but this particular point of confusion has been common for well over a decade and I think needs to be clarified as often as possible. You DO NOT need to have autoconf or automake installed to build a project that used those tools. The entire point of the autotools is to generate a build system that will build on a system using only the standard tools (make, a c compiler, sh, and few others.) Unfortunately, many developers release tarballs that do not build cleanly. If you unpack the tarball and it does not contain a configure script, or if the configure script is broken, that is a bug in the package. The solution is absolutely not to install autoconf/automake/libtool and try to produce a working configure script. The solution is to report the build error as a bug to the package maintainer.
The world would be a better place if Linux distributions stopped installing multiple versions of the autotools by default as less than .002% of the population needs those tools, and anyone who actually needs to have the tools should be capable of installing it themselves. Anyone incapable of acquiring and installing the tools has no business using them.
I've recently got acquainted with Boost library and I'd like to use it in my Xcode project. But sadly there is no HowTo or FAQ on how to do it :(
What's the sequence of actions to build and use Boost libraries in Xcode?
The easiest way I've found to do it is to install MacPorts, then you can install/build Boost via a single command:
sudo port install boost
Plus you get similar access to other open source software. The only downside I've found is that, like any other package management system, they are not always up to date with the latest version.
If you prefer Homebrew as your package manager, the command is:
brew install boost
I don't know how to use Boost from XCode (I'm not a Mac programmer), but building boost is usually done through their own build tool, bjam.
They have a guide to building boost here, and you can download the latest version of bjam here
Once it is built, you reference it from Xcode the same way you would any other library. The boost/include should be added to your include path, and the libraries in boost/lib can be referenced for the boost libs that require it.
To build boost on a mac, follow the unix variants getting started page (http://www.boost.org/doc/libs/1_39_0/more/getting_started/unix-variants.html). You won't use Xcode directly to perform the build, but once complete you can add the boost include paths and dylib's to your Xcode project.
I found that to build Boost 1.41.1 on MacOS, you need to do the following:
Download boost 1.46.1 from here: http://sourceforge.net/projects/boost/files/boost/1.46.1/
Unpack the file
Open terminal, cd to the install directory, and do the following:
chmod u+x configure.sh
cd tools/build/v2/engine/src
chmod u+x build.sh
Then go back to the install directory, and:
./configure.sh
If that runs successfully, it will tell you to run:
./bjam
That's it.. for whatever reason, I needed to set those permissions manually before it would work.
su - root
enter root password and then run below as root
/opt/local/bin/port install boost
If you have never logged in as root or forgotten your password, here are the steps to reset root password
http://support.apple.com/kb/HT1528?viewlocale=en_US&locale=en_US
For most of the boost libraries, there's nothing to build, it's all in header files.
The remainder of the instructions are here.
Currently I'm very happy with using Pete Goodliffe's script which builds a framework from the Boost source package for both iOS and Mac. Drag and drop it into a project and it works!
There are multiple versions of the script out there. Here's one:
https://gist.github.com/faithfracture/c629ae4c7168216a9856/61be257e1c0839c85743777d0687becad9913bf7
Elaboration of Ferrucio's answer:
Install Boost using MacPorts (sudo port install boost) or Homebrew (brew install boost).
Find the path to the Boost header files (it should be in /opt/homebrew/include if you're using Homebrew).
Add the path to System Header Search Paths in the Build Settings of your Xcode target.
IMPORTANT NOTE: If you add the path to User Header Search Paths instead of System Header Search Paths, as other users suggested, then your code will fail to build, since the Boost files use angled-includes (#include <boost/filename.hpp>) to include each other. Angled-includes are only for including system library headers, and thus they only work if Boost is in the System Header Search Paths.
You can read about the difference between angled-includes and quoted-includes here.
