Hi, all: I don't know if I misunderstand the purpose of this mail-list. But I don't know somewhere else to ask.
Recently, I compiled a program on a Debian 5.0.2 system with default configurations. Then I got 'FATAL: kernel too old' message when I tried the binary file on a SLES9 system with the kernel 2.6.5. 'file foo' said: 'foo: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.8, not stripped' So I guessed the problem might be that GLIBC is not old enough ( with --enable-kernel=2.6.8 ). Then I downloaded libc6-dev_2.3.6.ds1-13etch9+b1_i386.deb, and extracted libc.a from it. After that, I compiled again: $ gcc -Wall -Wextra -pedantic -O0 -ggdb -std=gnu99 -D_XOPEN_SOURCE=500 -c -o foo.o foo.c $ gcc -Wall -Wextra -pedantic -O0 -ggdb -std=gnu99 -c -o main.o main.c $ gcc -Wall -Wextra -pedantic -O0 -ggdb -std=gnu99 -static -nostdlib -o foo main.o foo.o old-libc/libc.a `gcc -print-libgcc-file-name` I got '/usr/bin/ld: warning: cannot find entry symbol _start; defaulting to 00000000080480a0' during compilation. _Q1_: is it safe to ignore this warning, since the program looks good now? _Q2_: what can I do to eliminate this warning? Then I tried exact the same steps on another Debian 5.0.2 amd64 system. Of course, I replaced libc6-dev_2.3.6.ds1-13etch9+b1_i386.deb with libc6-dev_2.3.6.ds1-13etch9_amd64.deb. _Q3_: how can I get rid of the errors below.
