Hi Everybody,

I’m trying to compile the example from the Demo/PC directory natively on linux, using gcc, but without success.

I currently using the follow command to compile the source. Inside the directory I do:

i586-mingw32msvc-gcc \  
-I. \  
-I$(FREERTOS\_PATH)/Source/include \  
-I$(FREERTOS\_PATH)/Source/portable/oWatcom/16BitDOS/PC \  
-I$(FREERTOS\_PATH)/Source/portable/oWatcom/16BitDOS/common \  
-I…/Common/include \  
main.c \  
./FileIO/fileIO.c \  
./ParTest/ParTest.c \  
$(FREERTOS\_PATH)/Source/croutine.c \  
$(FREERTOS\_PATH)/Source/list.c \  
$(FREERTOS\_PATH)/Source/queue.c \  
$(FREERTOS\_PATH)/Source/tasks.c \  
$(FREERTOS\_PATH)/Source/portable/oWatcom/16BitDOS/PC/port.c \  
$(FREERTOS\_PATH)/Source/portable/oWatcom/16BitDOS/common/portcomn.c \  
$(FREERTOS\_PATH)/Source/portable/MemMang/heap\_2.c  
-o pc

Did I’m missing something, like an include or a source?

Another question: Do I need to install/configure openwatcom in order to work?

The result of the above build is the errors:

…/…/Source/queue.c: In function ‘xQueueGenericSend’:  
…/…/Source/queue.c:480: error: expected ‘(’ before ‘{’ token  
…/…/Source/queue.c:480: error: expected identifier or ‘(’ before numeric constant

…. (more errors)….

Thanks in advance!

The PC demo is 16bit real mode code and uses DOS style BIOS calls, I don’t think it will work on top of Linux. There is a Linux simulator though.
