Build emWin library in MCUXpresso for FRDM-K64F

[GuillaumeAudirac]

Prior to configuring the emWin library for a new display, I want to test the latest emWin library on the FRDM-K64F platform. For this purpose:

1. I downloaded the SDK_2.x_FRDM-K64F
2. I created a default project based on the gui_demo SDK example
3. I compiled on MCUXpresso IDE v10.0.2_411 (successfully)

As it is based on a static emWin library v5.38a, I downloaded the latest emWin v5.42i release.

From there, I updated the project:

• I deleted the reference to the static emWin library
• I added a folder emwin/emWin_source
• I updated the emWin_Config folder with the default files (from Start/Config, 5 files).
• I updated the emWin_header folder with the default files (from Start/GUI/[Core, DisplayDriver, Widget], as well as WM.h, WM_GUI.h, 117 files)
• I filled up the emWin_source folder with the default files (from Start/GUI/[Core, DisplayDriver, Widget], 447 files)
• In the project properties, I added the emWin_source folder to the include paths for the compiler and assembler.

Finally, when compiling from the source, I came up with many errors, mainly undefined references.

The build log is attached.

Could you please provide some help me on this?

I solved the issues:

• additional folders to be added: Font, MemDev, WM, ConvertColor, ConvertMono
• skip GUIConf.c and LCDConf.c files as the definitions are already manually added to the file board/emwin_support.c
• remove the file SIMConf.c, not needed

The build is now successful.
