GWindows examples ↩

Ada project Directory gwindows-examples\ contains Ada code examples coming from various websites - mostly from the GWindows project.

We support the following build tools :

Build tool Build file
gnatmake.exe 1 –
gprbuild.exe build.gpr

tutorial1 Example

Command build.bat 2 relies on gnatmake.exe to generate the executable target\tutorial1.exe from the Ada source file tutorial1.adb :

> build -verbose run
Compile 1 Ada source file to directory "target\obj"
Execute program "target\tutorial1.exe"

Command gprbuild.exe reads its configuration from file tutorial1.gpr and generate the executable target\tutorial1.exe :

> gprclean& gprbuild& target\tutorial1.exe
using project file tutorial1.gpr
using project file tutorial1.gpr
Compile
   [Ada]          tutorial1.adb
Bind
   [gprbind]      tutorial1.bexch
   [Ada]          tutorial1.ali
Link
   [link]         tutorial1.adb

tutorial2 Example

Command make.exe reads its configuration from file Makefile and relies on gnatmake to generate the executable target\tutorial2.exe from the Ada source file tutorial2.adb :

> make run
"C:/opt/GNAT/2021/bin/gnatmake.exe" -q -gnat2022 -we -aI"C:\opt\GWindows-20221113\gnatcom\framework" -aI"C:\opt\GWindows-20221113\gwindows\framework" -D "target/obj" -o "target/tutorial2.exe" src/tutorial2.adb
target/tutorial2.exe

Command gprbuild.exe reads its configuration from file tutorial2.gpr and generate the executable target\tutorial2.exe :

> gprclean& gprbuild& target\tutorial2.exe
using project file tutorial2.gpr
using project file tutorial2.gpr
Compile
   [Ada]          tutorial2.adb
   [Ada]          gwindows-windows-main.adb
Bind
   [gprbind]      tutorial2.bexch
   [Ada]          tutorial2.ali
Link
   [link]         tutorial2.adb

[1] Gnatmake ↩

GNU tools such as gcc, gnatmake, objdump and windres are available both in the MSYS installation and in the GNAT 2021 installation; we use the tools from the MSYS installation which have newer versions.
