Re: [avr-gcc-list] Compilation Problem

[Russell Strong]

Just for fun I erase the RPMS and installed the binary ones provide that
were compiled on redhat 7.3.  Now I get ( with the makefile provided in
the demo )

address@hidden avr]$ make
avr-gcc -g -Wall -Os -mmcu=at90s2333    -c -o demo.o demo.c
avr-gcc -g -Wall -Os -mmcu=at90s2333  -Wl,-Map,demo.map -o demo.elf
demo.o
/usr/lib/gcc-lib/avr/3.3/../../../../avr/bin/ld: skipping incompatible
/usr/lib/gcc-lib/avr/3.3/../../../../avr/lib/libc.a when searching for
-lc
/usr/lib/gcc-lib/avr/3.3/../../../../avr/bin/ld: skipping incompatible
/usr/avr/bin/../lib/libc.a when searching for -lc
/usr/lib/gcc-lib/avr/3.3/../../../../avr/bin/ld: cannot find -lc
make: *** [demo.elf] Error 1
address@hidden avr]$

It's also worth noting that if I type the link command manually using
avr-ld instead of avr-gcc, i.e.

avr-ld -Map demo.map -o demo.elf demo.o

It works...  Then continue on with

address@hidden avr]$ make all
avr-objdump -h -S demo.elf > demo.lst
avr-objcopy -j .text -j .data -O ihex demo.elf demo.hex
avr-objcopy -j .text -j .data -O binary demo.elf demo.bin
avr-objcopy -j .text -j .data -O srec demo.elf demo.srec
avr-objcopy -j .eeprom --change-section-lma .eeprom=0 -O ihex demo.elf
demo_eeprom.hex
avr-objcopy -j .eeprom --change-section-lma .eeprom=0 -O binary demo.elf
demo_eeprom.bin
avr-objcopy -j .eeprom --change-section-lma .eeprom=0 -O srec demo.elf
demo_eeprom.srec
address@hidden avr]$

Since this seems to be a newly encountered problem.  I'm wondering if it
may be a Redhat 9.0 thing. Are you using Redhat 9.0 Theodore?  Is anyone
else using Redhat 9.0 with these RPMS?
