*EQL5 is a (extended) Qt5 port of EQL/Qt4* --- [wiki](https://gitlab.com/eql/EQL5/wikis/home) [mailing list](https://groups.google.com/group/eql-user/topics) contact: pls.153, protonmail **Many thanks** to the users of the eql-user mailing list and to private mail contacts for your contributions and testing! Build (for the impatient) ------------------------- In `src/` do: ``` $ ecl -shell make # will take a while $ qmake eql5.pro $ make $ sudo make install # Unix ``` *Please note that the eql5 libs are now installed in `$$[QT_INSTALL_LIBS]`, so you'll need to manually remove any eventually present old version from e.g. `/usr/lib/`.* Now you should be able to run `eql5`. If there are problems, or you want more info, see detailed instructions below. P.S: If you are on **Arch Linux**, see also [AUR recipe](https://aur.archlinux.org/packages/eql5-git/) (thanks to 'VanLaser'). Tested with: ------------ *Note from 2020: the following list is outdated; everything should work fine with current versions, I tested on all 3 platforms.* *Linux* (development platform), with both gcc and clang: * ECL 16.1.2 * Qt 5.5.1 (with module `:webkit`) * Qt 5.8 (with module `:webengine`) *Windows/32*: * MSVC 2010, MinGW 4.9 * ECL git 2017-02 / 32 bit * Qt 5.5.1 / 32 bit (precompiled from qt.io archives; contains WebKit) *Windows/64*: * MSVC 2015 * ECL git 2016-11 / 64 bit (see flag in Makefile) * Qt 5.7 / 64 bit (precompiled from qt.io archives; WebKit is not included) *macOS*: * not tested personally, but has been reported to work (with clang) -- MinGW note: in order to build successfully, I needed to: * change a typedef in `ecl.h` (after building ECL); see compile error; * comment out all offending lines of module `:quick`; see SGTexture related linker errors; the source files are in `eql5/src/gen/quick/`; Requirements ------------ * ECL (both threads & unicode enabled, as by default) * Qt >= 5.5 QtWebKit note: If you want QtWebKit included in the official downloads from qt.io archives, you need to choose Qt 5.5, and not later versions! QtWebKit will continue to work with versions > 5.5, but it has to be compiled manually (which is not fun). QtWebKit has a better, more native integration with Qt than QtWebEngine, see for example `QWebElement`, which doesn't exist in QtWebEngine. Prepare ------- Install the ECL sources, and build it from the sources (ECL needs to be built with the same compiler you'll use to compile EQL5). Just use the standard configuration of ECL (both threads & unicode enabled). Download Qt5 from here (pay attention to choose the version compiled with the same compiler you'll use to compile EQL5): [https://download.qt.io/archive/qt/](https://download.qt.io/archive/qt/) Qt4/Qt5 note: You can have both old EQL (Qt4) and EQL5 (Qt5) installed in parallel (exe and lib names differ). If you have both Qt4 and Qt5 installed, you can use the following environment variable to switch between the both on Unix (which requires the different Qt `bin/` directories to be in `PATH`): ``` $ export QT_SELECT=5 ``` Please note that you should build EQL5 in a path where you will keep it (you can't move around the whole file tree later, since the path to find some example files is hard-coded in the executable.) Build ----- (N.B. for rebuilding, please see `README-2-REBUILD`) *Windows* You first need to adapt the file `src/windows.pri` (include & library paths). You also should add your eql5 directory (for eventual C++ modules), e.g: ``` INCLUDEPATH += ... c:/eql5/src LIBS += ... -Lc:/eql5 ``` Since EQL5 requires the C compiler anyway (not the bytecode compiler), you should put this line in your `~/.eclrc`: ``` (require :cmp) ``` *MSVC* Substitute `make` with `nmake`. *MinGW* If `make` is stuck in an infinite loop of creating the `Makefile`, just remove the line `include(windows.pri)` from your `*.pro` file, setting eventually needed paths in your `~/.profile` instead. *SailfishOS* Run this before running `qmake`: ``` $ export SAILFISH=sailfish ``` ### 1) Build Lisp lib ``` $ cd src $ ecl -shell make.lisp ``` ### 2) Build C++ lib, exe, modules Edit `eql5.pro` and comment out all modules you don't need. Then run: ``` $ qmake eql5.pro $ make $ sudo make install # Unix only ``` This will build the shared library, the executable and the modules. If you ran `make install`, you'll find the installed files here: ``` /usr/bin/ /usr/lib/ /usr/include/eql5/ ``` ### 3) Environment *Linux* N.B. skip this if you did `sudo make install` You need to create links to EQL5, something like: ``` $ cd /usr/lib $ sudo ln -s ~/eql5/libeql5.so.1 libeql5.so.1 $ cd /usr/bin $ sudo ln -s ~/eql5/eql5 eql5 ``` *macOS* N.B. skip this if you did `sudo make install` You need to create links to EQL5, something like: ``` $ cd /usr/lib $ sudo ln -s ~/eql5/libeql5.1.dylib libeql5.1.dylib $ cd /usr/bin $ sudo ln -s ~/eql5/eql5.app/Contents/MacOS/eql5 eql5 ``` *Windows* Add your EQL5 directory to the `Path` environment variable, see: <Control Panel:System:Advanced:Environment Variables> Run --- You can run a simple interactive REPL UI doing: ``` $ eql5 -qgui ``` To run a Lisp file without top-level, do: ``` $ eql5 examples/2-clock ``` (If you don't see the application window, it might be in the background. Use your taskbar to show it.) If you start the EQL5 executable without arguments, it will start the usual ECL top-level (without processing Qt events). To *not* load `~/.eclrc` on startup, do: ``` $ eql5 -norc ``` To quit the tool, do: ``` (eql:qquit) ; or (eql:qq) ``` In order to run (sort of) a top-level processing Qt events, do: ``` $ eql5 -qtpl ``` Note: If you want to use `ecl-readline` together with `-qtpl`, just compile `~/.eql5/lib/ecl-readline.lisp` (which depends on the **readline** C library). It will then be loaded automatically on startup: ``` $ cd ~/.eql5/lib $ ecl --compile ecl-readline.lisp ``` N.B: Using readline, you will often need to `reset` (command) your console/shell after EQL5 finished working, especially during development time or other exits than `(eql:qquit)`. An alias in `~/.bashrc` can help to make this less annoying, since you might not see the command while typing: ``` $ alias r=reset ``` Qt modules ---------- (`help`, `multimedia`, `network`, `quick`, `sql`, `svg`, `webengine`, `webkit`) N.B. skip this if you already built from `eql5.pro` (see above) To build an EQL5 module (corresponding to a Qt module), do the following in `src/`: ``` $ qmake module_.pro # e.g. qmake module_network.pro $ make $ sudo make install # Unix only ``` *Linux, macOS* (N.B. skip this if you did `sudo make install`) You need to create links to the modules, see EQL5 shared library above. In Lisp, use function `qrequire` to load a module: ``` (qrequire :network) ``` Tips ---- You might want to put this in your `~/.eclrc` file: ``` #+eql (setf eql:*qtpl* t ; same as -qtpl eql:*break-on-errors* t) ``` Please see also example `examples/X-extras/CLOS-encapsulation.lisp` for encapsulation of Qt classes in Lisp classes or structs (that is, Lisp classes that behave like a Qt class if passed to Qt functions).
