linker input file unused because linking not done

Other Parts Discussed in Thread: TMS320C6474

hi all,

I had compiling a httpserver for coldfire without error and I want to compile it  for TMS320C6474

There is no error in the programs but i had a following problem of linking:

gcc: ./file.o: linker input file unused because linking not done

file is a program file that's repeated for all files

to link these files.o we use -Wl,-ar. but i have therefore another error:

ERROR: argument to option -op ("0-3") is out of range (must be from 0 to 3)

I want to know what reasons for these problems are? and how to remedy  it?.

thanks for your help

    Hi,

    Are you using a make file for compiling?

    If yes, post you make file here, else post your commands here.

    There seems to be error there, probably mixing source files and object files in 1 command

    Regards,

    yes, i use a makefile whitch call other makefiles in 5 directories but we can use the commandes lines ; for example in the directory factory there are many sources that compiles files simultaneously with the following command :

    /home/coralie/noyau_linux/build_dir/bin/c64xplus-linux-gcc -Wall -O2 -Wl,-ar  -DGSOAP=1 -DCOLDFIRE=0 -DLINUX=1 -D__USE_LOGFILE__=0 -DPRINTF_DEBUG=0 -DSSI_VERSION=101 -I../pgm/h -I../pgm/gen -I../pgm/import -g -w -c -fmessage-length=0 -MMD -MP -MF"pgm/ws/factory/admin_WS.d" -MT"pgm/ws/factory/admin_WS.d" -o"pgm/ws/factory/admin_WS.o" "../pgm/ws/factory/admin_WS.c"

    ERROR: argument to option -op ("0-3") is out of range (must be from 0 to 3)

     

    make: *** [pgm/ws/factory/admin_WS.o] Error 1

    -normally when we replace /home/coralie/noyau_linux/build_dir/bin/c64xplus-linux-gcc  by gcc, the compilation of these sources locally for the pc does not pose any problem

    -but as we see, the compilation stops at the first program with this error

    ERROR: argument to option -op ("0-3") is out of range (must be from 0 to 3)

    when using the-E option to gcc ie avoid linker (not link), all programes will compile without error. but not link it to make one executable.

    So the problem is not to use the-E option and at the same time exceed the initial error

    thanks for your help
