Package: gcc-4.1
Version: 4.1.2-5
Severity: critical
Tags: d-i
The upgrade of gcc from 4.1.2-4 to 4.1.2-5 is breaking builds of the
installer. The problem seems to be that a stripped library no longer
contains dynamic symbol information.
I've traced this to the following series of commands, which are executed
by mklibs (first command simplified; full command attached):
gcc -nostdlib -nostartfiles -shared -Wl,-soname=libc.so.6 -u \
-o ./tmp/netboot/tree/lib/libc.so.6-so \
/usr/lib/libc_pic/soinit.o /usr/lib//libc_pic.a /usr/lib/libc_pic/sofini.o
/lib//ld-linux.so.2 \
-Wl,--version-script=/usr/lib//libc_pic.map -lgcc
-L./tmp/netboot/tree/lib -L./tmp/netboot/tree/usr/lib
-L./tmp/netboot/udeblibs -L/lib/ -L/usr/lib/ -L/usr/X11R6/lib/
-L./tmp/netboot/tree//usr/lib/cdebconf
objcopy --strip-unneeded -R .note -R .comment
./tmp/netboot/tree/lib/libc.so.6-so ./tmp/netboot/tree/lib/libc.so.6-so-stripped
readelf -s -D -W ./tmp/netboot/tree/lib/libc.so.6-so-stripped
With 4.1.2-5, the last command results in:
Dynamic symbol information is not available for displaying symbols.
With 4.1.2-4, the last command results in:
