Add #include for your peripheral acces layer into Syscalls.c (stm32f4xx.C/C++ Build -> Settings -> Tool Settings -> C++ Compiler -> Symbols -> add CPPUTEST_STD_C_LIB_DISABLED.C/C++ Build -> Settings -> Tool Settings -> C++ Linker -> Libraries -> add 'CppUTest'.

C/C++ Build -> Settings -> Tool Settings -> C++ Linker -> Library search path ->.Select your debugging tool (ST-LINK in my case).Check Generate system calls file (enable I/O.File -> New -> C++ Project -> Embedded C++ Project -> Embedded C++ Library (I have named my project CppUTestTest).

This outputs a libCppUTest.a file in your library's Debug folder.

C/C++ Build -> Settings -> Tool Settings -> General -> Runtime Library -> Reduced C and C++.

C/C++ Build -> Settings -> Tool Settings -> C++ Compiler -> General -> C++ standard -> gnu++98.

C/C++ Build -> Settings -> Tool Settings -> C++ Compiler -> Symbols -> add CPPUTEST_STD_CPP_LIB_DISABLED.

C/C++ Build -> Settings -> Tool Settings -> C++ Compiler -> Directories -> add /include.

In your library's src folder edit IEEE754ExceptionsPlugin.cpp line 31 so it looks like this: #ifdef CPPUTEST_USE_FENV (this turns off support for floating-point enviroment).

Open the UtestPlatform.cpp you have just copied and substitute the lines 259-288 with lines 198-218 from src/Platforms/Keil/UtestPlatform.cpp (this makes all mutex functions just dummies).

From CppUTest root directory: Copy src/Platforms/Gcc/UtestPlatform.cpp to your library's src folder.

From CppUTest root directory: Copy all sourcefiles from src/CppUTest and src/CppUTestExt to your library's src folder.

Uncheck 'Disable C++ exception handling'.

Select your target hardware (STM32F401RE in my case).

File -> New -> C++ Project -> Static Library -> Embedded C++ Library.
