Dose rl78-elf-ld support g10 processor?
Hi,
Dose rl78-elf-ld support g10 processor?
I use GCC for Renesas 4.9.2.201801-GNURL78 Linux Toolchain, but I don’t use e2studio.
I develop on makefile project.
I can compile to use ‘-mcpu=g10’ option on rl78-elf-gcc.
But I cannot link object files.
rl78-elf-ld returns errors below:
rl78-elf-gcc -mcpu=g10 -nostdlib -Wl,-Map,led_blink.map -T ../generate/linker_script.ld -o led_blink.elf build/generate/start.o build/led_blink.o build/hwinit.o build/generate/inthandler.o build/generate/vects.o

I can link object files is compled using ‘-mcpu=G13’ option at same source files.
Hello,
Unfortunately, based on the information provided, we can’t reproduce the issue with a sample project using the GNURL78-ELF Toolchain v4.9.2.201801.
Could you please specify what commands did you use for compilation? Or, if possible, could you please send us a demo project to try and reproduce the problem?
– Best regards,
The GNU Tools Team

How do I send you my project?Thank you.

Thank you for your activities.
I solved the problem myself.
I returned using e2studio on Windows, and make sample project.
Then, I built empty project to check build options.I mistaked option for assemble “start.s”.
I losted option “-mcpu=g10″ and assembled start.se2studio default option for start.s on g10 is below:
rl78-elf-gcc -O0 -fdata-sections -g2 -Wstack-usage=40 -mg10 -x assembler-with-cpp -Wa,–gdwarf2 -I”C:/Users/isaka/e2_studio/workspace/test/src” -Wa,-adlhn=”start.lst” -MMD -MP -MF”generate/start.d” -MT”generate/start.o” -c “../generate/start.S” -o “generate/start.o”
