Hi, I am trying to convert c file that compiled and debugged under
IAR system into the gcc environment. Currently, i am running into the
problem of that in gcc, it really doesn't recognize the msp430x140x.h
file. Instead, I was told that there is a io.h file built in gcc.
However, when I try to #include <io.h> in place of #include
<msp430x140x.h>, gcc popped out this message:
In file included from final_7.c:3,
from testadc.c:2,
from test_3.c:3:
TimerB.c:30: io.h: No such file or directory
In file included from TimerB.c:32,
from final_7.c:3,
from testadc.c:2,
from test_3.c:3:
TimerB.h:152: io.h: No such file or directory
I am wondering if anyone know about how to solve this problem. One
more question, what are some of things that gcc doesn't support that
IAR does. We are currently using IAR system for our program, however,
we are trying to convert our programs to be compiled under gcc. Thank
you very much.
Sincerely

Hello,
Are you sure it's <msp430x140x.h> and not <msp430x14x.h>? You
definitely
need to include that file. I believe there are some macros defined in
<io.h> and <signal.h> that are sometimes needed - like EINT().
Which model of MSP430 are you compiling for? What platform are you using to
run mspgcc? Windows, Linux, Unix? If it's Windows, did you install it in
the default directory (as is recommended) or did you install in a
different one?
If you don't figure out the problem right away, you should try the
mspgcc-users mailing list.
HTH,
Ale

Hello, thank you so much for replying. I am pretty sure that we are
using msp430x14x.h, sorry I typed one more 0. We are running on the
Windows and are using the msp430F149. Thank you for your advice, I
really appreciate it.

Hello, We also jump between the IAR and gcc compilers... the #include <msp430x14x.h> is needed by both. In your makefile, there should be lines similar to these : # # put the path name of the root of the MSP430 includes directory here INCLUDESROOT = "C:\Progra~1\mspgcc\msp430\include" # # gcc expects the C compiler to be declared in the variable CC and it's flags in CFLAGS CC= C:\Progra~1\mspgcc\bin\msp430-gcc CFLAGS= -mmcu=$(MCU) -g -Os -Wall -I$(INCLUDESROOT) -I$(INCLUDESROOT) \MSP430 -I$(INCLUDESROOT)\sys # # Basically, you're telling the compiler the path(s) to use when searching for files you #include. My guess is you have this set incorrectly - go to where you installed msp-gcc and find the file in question (mine are in "/msp430/include") and reference it's path in the INCLUDESROOT variable. Once you get the paths straight, you'll hit the more annoying problem - that gcc and IAR have different ideas about how interrupt handler functions should be declared. The easy fix is to use #ifdef __IAR IAR interrupt definitions go here #else ... gcc versions go here #endif and then put __IAR into the list of defined variables in IAR's compiler. Anyone got some macros written to automate this? hope this helped... --- In msp430@msp4..., "yiming_yin" <yiming_yin@y...> wrote: > Hello, thank you so much for replying.
