Hello all,
I am using Yagarto tool chain. If I use printf in my code I am getting
an
linker error!
>> undefined referenced to 'printf'<<
Link flags that I used as below;
LFLAGS = -nostartfiles -Map $(TARGET).map,--cref
LFLAGS += -lc -lgcc
LFLAGS += -L "C:\Yagarto\lib\gcc\arm-elf\4.3.2\libgcc.a"
#LFLAGS += -L "C:\yagarto\arm-elf\lib\libc.a"
And Compiler flags;
CFLAGS += -I. -c -g -mcpu=$(MCU) -fverbose-asm
CFLAGS += -O$(OPT) -std=gnu99
CFLAGS += -Wall -Wcast-align -Wcast-qual -Wimplicit
CFLAGS += -Wpointer-arith -Wswitch
CFLAGS += -Wredundant-decls -Wreturn-type -Wshadow -Wunused
yagarto information;
binutils: 2.18
gcc: 4.3.2
newlib: 1.16.0
gdb: 6.8.50-20080308-cvs

Please re-read the PM I have sent in reply to your e-mail. As already requested there: please create a minimal example including all sources, linker-script and (complete) makefile which shows the issue. Pack it into a ZIP-archive and attach it to a message. It's difficult to help if you show just a few lines from a makefile. Before you send the example, please review the makefile: - I suggest to use the frontend (...gcc) to call the assembler - Try to avoid usage of absolute pathes in the makefile. - Use the frontend to call the linker, do not call ...-ld directly. With this there is no need to set absolute pathes to the used libc. I will try to reproduce the issue here with a GNU toolchain from a non-Yagarto package but maybe other reader of the forum can test with tools from Yagarto once you have uploaded your example.
