I have trouble converting the existing stm32 ports to crosswork environement. i started by converting the existing stm32 iar port and the primer port but my code won t compile . I tried a diffrent approach by using a working demo in rowley from the stm32 package. and then add the freertos sources and fucntionnality but i get the same compilation errors all the time. the compiler messagfe is: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘\_\_attribute\_\_’ before ‘typedef’   #ifndef \_\_crossworks\_H #define \_\_crossworks\_H #if defined(\_\_CROSSWORKS) #define \_\_SIZE\_T unsigned #define \_\_PTRDIFF\_T int typedef unsigned char \*\_\_va\_list; #pragma intrinsic(\_\_va\_base) #elif defined(\_\_CROSSWORKS\_ARM) #define \_\_SIZE\_T unsigned long #define \_\_PTRDIFF\_T int \*\*\*\*\*\> typedef \_\_builtin\_va\_list \_\_va\_list; \<\*\*\*\*\*\*\*\*\*\*\*\*\*\* pointing to the line above in \_\_crossworks.h file. can you help me find what s going on? ---

Could be order in which include files are loaded. What was the source code or file that was added before this error came up. Maybe ask Rowley support? ---

If nothing changed since then, all you have to do is define GCC\_ARMCM3 since Rowley use the GCC compiler, so you must use the GCC port instead of the IAR port. Regards ---

I don’t have RIDE so I can’t check it for myself. I’m trying to use this port (with some changes of course) with Rowley and the build process stops at assert line (in . Searching though sources shows no assert definition.  It’s defined for KEIL and IAR though.
