Re: [Iup-users] Visual Studio project not compiling

Thanks for the reply. I am creating a Visual Studio project using the wizard. The method you suggested is very difficult for me and not very clear. I would still like to understand why ip.lib, included in the necessary project parameters, is not linked. I plan to continue creating projects with the help of the wizard, this method suits me perfectly.

How did you generate your project files? I generally using CMake to create the sln and cproject files automatically as it is otherwise a bit of a chore. Also, CMake is IUP's native build system, which can be helpful.

Another question is, how did you obtain IUP? My recommendation is to use PMM to get all dependencies automatically, including IUP itself, from an appropriate package source such as vcpkg.

This should be a good starting point (not at my main machine right now so I can't easily access my very messy project files to ensure this is 100% correct but let me know if it doesn't work):

********** CMakeLists.txt **********

```cmake
cmake_minimum_required(VERSION 3.15)
project(iup_example)

set(CMAKE_CXX_STANDARD 17)

# Include PMM
include(pmm.cmake)
pmm(VCPKG
PACKAGES
iup
cd
im
)

# Find packages
find_package(IUP CONFIG REQUIRED)
find_package(CD CONFIG REQUIRED)
find_package(IM CONFIG REQUIRED)

# Add the executable
add_executable(iup_example main.cpp)

# Link libraries
target_link_libraries(iup_example PRIVATE
IUP::iup
IUP::iupcontrols
IUP::iupcd
IUP::iupim
CD::cd
IM::im
)

# Copy LED file to build directory
configure_file(${CMAKE_SOURCE_DIR}/example.led ${CMAKE_BINARY_DIR}/example.led COPYONLY)
```

********** main.cpp **********

```cpp
#include <iup.h>
#include <iupcontrols.h>
#include <cd.h>
#include <cdiup.h>
#include <im.h>
#include <im_image.h>

int main(int argc, char **argv) {
IupOpen(&argc, &argv);
IupControlsOpen();

cdInitContextPlus();
cdInitContextIup();

imInitialize();

Ihandle* dlg = IupLoad("example.led");
if (!dlg) {
IupMessage("Error", "Can't load LED file");
return 1;
}

IupShowXY(dlg, IUP_CENTER, IUP_CENTER);

IupMainLoop();

IupClose();
imFinialize();
return 0;
}
```

********** example.led **********

``iupled
dialog = DIALOG[TITLE="IUP Controls Example"]
(
VBOX
(
HBOX(LABEL[TITLE="Button:"], BUTTON[TITLE="Click Me"])
HBOX(LABEL[TITLE="Toggle:"], TOGGLE[TITLE="On/Off"])
HBOX(LABEL[TITLE="Text:"], TEXT[VALUE="Enter text here"])
HBOX(LABEL[TITLE="List:"], LIST[1="Item 1", 2="Item 2", 3="Item 3"])
HBOX(LABEL[TITLE="Tree:"], TREE[NAME="tree"])
HBOX(LABEL[TITLE="Tabs:"], TABS(VBOX(LABEL[TITLE="Tab 1"]), VBOX(LABEL[TITLE="Tab 2"])))
HBOX(LABEL[TITLE="Progress:"], PROGRESSBAR[VALUE="50"])
HBOX(LABEL[TITLE="Val:"], VAL[MIN=0, MAX=100, VALUE=50])
HBOX(LABEL[TITLE="Dial:"], DIAL[DENSITY=10])
HBOX(LABEL[TITLE="Gauge:"], GAUGE[VALUE=0.7])
HBOX(LABEL[TITLE="ColorBrowser:"], COLORBROWSER[])
HBOX(LABEL[TITLE="MatrixEx:"], MATRIXEX[NUMCOL=3, NUMLIN=3])
HBOX(LABEL[TITLE="GLCanvas:"], GLCANVAS[RASTERSIZE=100x100])
HBOX(LABEL[TITLE="MglPlot:"], MGLPLOT[RASTERSIZE=200x150])
HBOX(LABEL[TITLE="Plot:"], PLOT[RASTERSIZE=200x150])
)
)
```

********* to build VisualStudio project files **********

1. Via the Start Menu, find an item named "Developer Command Prompt for VS [Your Version]" (e.g., "Developer Command Prompt for VS 2022").

2. Open it. You'll see a command prompt window with a message indicating it's set up the environment for Visual Studio.

3. Navigate to your project directory:
```
cd path\to\your\project
```

4. Then, run the CMake command to generate your project files:
```
mkdir build
cd build
cmake .. -G "Visual Studio 17 2022" -A x64
```

(Adjust the Visual Studio version as needed to match the Command Prompt version you opened)

5. After CMake generates the files, you can either:
- Open the .sln file in Visual Studio, or
- Build from this same command prompt and still in the "build\" directory as above:

```
cmake --build . --config Release
```
Or
```
cmake --build . --config Debug


6. If you compiled via the command prompt as above, you can run the EXE via the appropriate path depending on the configuration you used

1. Debug Configuration:
```
[project_root]\build\Debug\iup_example.exe
```

2. Release Configuration:
```
[project_root]\build\Release\iup_example.exe
```

Hope this helps, and if not, please follow up!
