[ECOS] Chapter 13. Building and Running Sample Applications

[ECOS] Chapter 13. Building and Running Sample Applications

[luna]

Hi,

i would like to build the sample application in chapter 13.

i downloaded the pre-built standart tools by eCosCentric Limited 
(http://ecos.sourceware.org/getstart.html) -> gcc 3.2.1

my next step was to configure the minimal kernel for my bord with
eCos Config Tool and i follow the instruction in chapter 13.

My promt with the error (powerpc-eabi-gcc (GCC) 3.2.1 (eCosCentric)):

$ powerpc-eabi-gcc -g -I ecos_kernel/minimal_ecos_install/include 
application/hello.c -Lecos_kernel/minimal_ecos_install/lib -Ttarget.ld -nostdlib
/ecos-g/DOKUME~1/ecos/LOKALE~1/Temp/ccWb5Zig.o: In function `main':
/home/ecos/ec555_workspace/ecos/application/hello.c:7: undefined reference to 
`printf'
collect2: ld returned 1 exit status

My promt with the error (GNU C version 3.4.1 (powerpc-eabi)):

$ /gnutools/bin/powerpc-eabi-gcc -g -I ecos_kernel/minimal_ecos_install/include 
application/hello.c -Lecos_kernel/minimal_ecos_install/lib -Ttarget.ld -nostdlib
/ecos-g/DOKUME~1/ecos/LOKALE~1/Temp/ccW6G3NF.o(.text+0x20): In function `main':
application/hello.c:7: undefined reference to `printf'
collect2: ld returned 1 exit status

the verbose mode of gcc doesnt tell me more. so i change the prinf to 
diag_printf. now i can compile my sample project.

has someone an idea to remove my error?

The 'printf()' function would not be included in the packages used
by a minimal kernel.  Try building a more complete kernel library,
the default for example.
