I'm sure the info I'm asking is somewhere, but I couldn't find it.

NXP releases emWin precompiler libraries for their MCUs. It's important to know exactly how they are compiled (compiler options, linker options, macros, ...).

I agree with you, I just found out that EMWIN precompiled library has size restrictions on the size of my program. Whenever I use emWin_ARM7TDMI.a I get an error on my IAR system saying “Size limit exceeded (262 144 bytes).

I have the “STD” license from IAR; I should not be having size restrictions problems. I call IAR technical support to find out why I was having this error, and it turns out that emWin_ARM7TDMI.a was compiled under the “BL” AIR license which only allows 262 144 bytes.

Tested: When I replace emWin_ARM7TDMI.a for SEGGERDEMOv5_ARM_IAR_V5_4t_tl_ir.a (Trial version from SEGGER) my program compiles fine.

Can you provide me with a EMWIN precompiled library with no size restrictions?

Nothing special is written in that thread, except the link to the official NXP emWin library distribution: https://www.lpcware.com/content/project/emwin-graphics-library

Even in that page, I couldn't find any detailed info about the compilation process of pre-compiled libraries distributed by NXP, except the following minimal sentence:

Library is complied for multitasking(GUI_OS=1) with maximum number of tasks equal to four (GUI_MAXTASK = 4).
