Ethereum: Why am I getting this make error w/ 0.4.0rc1 on Ubuntu

Ethereum Build Error: Unknown Iconize Event Issue

The error you’re experiencing with 0.4.0rc1 on Ubuntu indicates that the Ethereum project is encountering an issue during the build process, specifically related to the ui.cpp file in the CMainFrame class. The warning suggests that there may be a problem with the wxIconizeEvent object.

Causes of the Issue:

• Missing or incorrect header files: Ethereum’s ui.cpp file uses the Windows API (Win32) functions for iconizing, such as SetIconImage and DestroyIconImage. However, Ubuntu does not provide a native Windows API equivalent. This may lead to missing or incorrect header files.

• Missing or corrupted library dependencies: Ethereum’s build process relies on various libraries, including wxWidgets (a cross-platform GUI toolkit). However, it’s possible that these libraries are not properly linked or installed on Ubuntu.

Workarounds and Solutions:

• Manually install the Windows API headers

  

  : You can download the necessary headers for the Windows API from [Microsoft’s Developer Community]( Extract them to a directory, such as /usr/include, and add it to your system’s include path.

• Install wxWidgets with the Ubuntu package manager: You can use the following command in the terminal to install wxWidgets:

sudo apt update

sudo apt install wxwidgets

• Configure Ethereum’s build process: Make sure that you have updated your CMAKE_BUILD_TYPE variable to match the desired configuration (e.g., release, debug). You can do this in the Makefile.unix file:

if [ "$CMAKE_BUILD_TYPE" = "Release" ]; then

  CMAKE_CXX_FLAGS -=Wl,-static-libgdi

else

  CMAKE_CXX_FLAGS +=-Wl,--static-libgdi

endif

• Manually link against the wxWidgets library: You can modify the CMAKE_LINKER variable in the Makefile.unix file to manually specify the linking flags for the wxWidgets library:

CMAKE_LINKER = $(LD) -lwxgtk-3.0 -static-libgdi -lgdi32

• Rebuild Ethereum with the updated build process: Once you’ve made the necessary changes to your Makefile.unix file, rebuild Ethereum using the following command:

make -f makefile.unix

Additional Tips:

• Make sure that your Ubuntu installation is up-to-date and compatible with the latest versions of the packages required by Ethereum.

• If you’re experiencing issues during build or runtime, consider creating a new build environment to isolate the problem.

By following these steps and troubleshooting strategies, you should be able to resolve the issue causing the ui.cpp error in 0.4.0rc1 on Ubuntu.
