skwarkowe boje #01 glibc

[Paweł Sikora]

po kilku godzinach walki udalo mi sie zbudowac skrosne narzedzia
a nastepnie za ich pomoca skrosnego glibca(64). potem juz przy
pomocy lekko poprawionych specy zbudowalem sobie natywne
gcc-3.4.1-snap(z multilibem) i binutils. caly toolchain ladnie
buduje binarki tak jak mysle, ze powinien, a mianowicie:

# gcc test.c -s -m32 -o test32
# gcc test.c -s -m64 -o test64

# file test32 && ldd ./test32 && time ./test32
test32: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), for GNU/Linux 
2.4.6, dynamically linked (uses shared libs), stripped
       libc.so.6 => /lib/libc.so.6 (0x7002c000)
       /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x70000000)

hello world
sizeof(char) = 1
sizeof(short) = 2
sizeof(int) = 4
sizeof(long) = 4
sizeof(long long) = 8
sizeof(void *) = 4

0.000u 0.000s 0:00.00 0.0%      0+0k 0+0io 61pf+0w

# file test64 && ldd ./test64 && time ./test64
test64: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), for GNU/Linux 
2.0.0, dynamically linked (uses shared libs), stripped
       libc.so.6 => /lib64/libc.so.6 (0xfffff80000104000)
       /lib64/ld-linux.so.2 => /lib64/ld-linux.so.2 (0xfffff80000000000)

hello world
sizeof(char) = 1
sizeof(short) = 2
sizeof(int) = 4
sizeof(long) = 8
sizeof(long long) = 8
sizeof(void *) = 8

0.000u 0.000s 0:00.00 0.0%      0+0k 0+0io 72pf+0w

teraz na natywnych 64-bitowych narzedziach i recznie zbudowanym glibcu(64)...

   49688 Jun 18 04:14 libgcc-3.4.1-0.20040611.1.sparc64.rpm

...chcialem przebudowac sobie jeszcze raz glibca ze speca do rpma, a tu zonk:

sparc-pld-linux-gcc ../sysdeps/generic/mempcpy.c -c -std=gnu99
-O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings
-fcall-used-g6 -m64 -mcpu=ultrasparc -mvis -fcall-used-g6
(..inkludy..)
../sysdeps/sparc/sparc64/memset.S: Assembler messages:
../sysdeps/sparc/sparc64/memset.S:248:
	Error: Architecture mismatch on "fzero".
	(Requires v9a|v9b; requested architecture is v9.)
../sysdeps/sparc/sparc64/memset.S:251:
	Error: Architecture mismatch on "fzero".
	(Requires v9a|v9b; requested architecture is v9.)

ktos ma jakis pomysl odnosnie powyzszego bledu?
