MSP430-GCC-OPENSOURCE: MSP430-GCC-9.2.0.0: Fatal error: MCU option requires a name

Part Number: MSP430-GCC-OPENSOURCE
Other Parts Discussed in Thread: MSP430FR2422

Invocation: 

/opt/ti/msp430-gcc-9.2.0.0/bin/msp430-elf-gcc -c -mmcu=msp430fr2422 -std=gnu11 -g -Os -Wall -pedantic -Wunused -ffunction-sections -fdata-sections -minrt -fomit-frame-pointer -fwrapv -MMD -I . -I ../Common -I/opt/ti/msp430-gcc-9.2.0.0/include  -o prog.o prog.c

error:

Assembler messages:
Fatal error: MCU option requires a name

however as specified

-mmcu=msp430fr2422

As this is a FATAL error I assume it will be treated with the highest priority?

    Hi Dave,

    to be honest; I personally have not played with msp430-gcc yet.  I will try to get this problem solved, but it might take some days.

    Meanwhile if someone else knows the solution, please don't hesitate....

    It would seem to be something about those specific options. I can replicate that error with the 9.2 compiler but not 8.3. On the other hand, it doesn't happen with the options I normally use with my code. Adding --verbose shows the actual as command line as:

     /usr/ti/gcc/bin/../lib/gcc/msp430-elf/9.2.0/../../../../msp430-elf/bin/as --traditional-format -mP -mcpu=msp430xv2 -gdwarf-sections -mi -o rump.o /tmp/ccZpYfMU.s
Assembler messages:
Fatal error: MCU option requires a name

    Deleting "-minrt" from the command line seems to have eliminated the error:

     /usr/ti/gcc/bin/../lib/gcc/msp430-elf/9.2.0/../../../../msp430-elf/bin/as --traditional-format -mP -mcpu=msp430xv2 -gdwarf-sections -o rump.o /tmp/cc36YG5q.s

    The only difference I can see is "-mi". My decoder ring doesn't reveal what that is supposed to mean as it isn't listed in the msp430 specific options.

    Looking at slau646e I see that -minrt is deprecated.

    As David said, -minrt is deprecated.

    GCC should be emitting an error when -minrt is used, indicating that it is deprecated. This will be fixed in the next release.

    Removing the option from the msp430-elf-gcc invocation will fix the error.

    Regards,

    Thank you Josef, this did indeed fix the error. Thanks David as well.
