I`m just downgraded from gcc-4.2.2 to gcc-4.1.2, selected it as a default compiler and when I try to start some programs like nmap, amarok, avidemux, blender and others I get error: _binaryname_: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by _binaryname_) I tried to use fix_libtool_files.sh and revdep-rebuild $ sudo fix_libtool_files.sh 4.2.2 $ sudo revdep-rebuild but none of them fixes error. Then I remerged all non-working packages and now they works! But I spent a lot of time to figure out what I need to remerge and why I need to done this. Below are some commands that I execute to find error: -------------------------------- nao@nao ~ $ ldd `which nmap` /usr/bin/nmap: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/bin/nmap) linux-gate.so.1 => (0xffffe000) libpcre.so.0 => /usr/X11R6/lib/libpcre.so.0 (0xb7f7a000) libpcap.so.1 => /usr/X11R6/lib/libpcap.so.1 (0xb7f4b000) libssl.so.0.9.8 => /usr/X11R6/lib/libssl.so.0.9.8 (0xb7f08000) libcrypto.so.0.9.8 => /usr/X11R6/lib/libcrypto.so.0.9.8 (0xb7de4000) libdl.so.2 => /lib/libdl.so.2 (0xb7daf000) libstdc++.so.6 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 (0xb7cc7000) libm.so.6 => /lib/libm.so.6 (0xb7ca3000) libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgcc_s.so.1 (0xb7c97000) libc.so.6 => /lib/libc.so.6 (0xb7b60000) libz.so.1 => /lib/libz.so.1 (0xb7b4d000) libbz2.so.1 => /lib/libbz2.so.1 (0xb7b3c000) /lib/ld-linux.so.2 (0xb7fab000) nao@nao ~ $ objdump -p `which nmap` | grep GLIBCXX 0x02297f89 0x00 14 GLIBCXX_3.4.9 0x08922974 0x00 04 GLIBCXX_3.4 nao@nao ~ $ nm -D /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 | grep GLIBCXX 00000000 A GLIBCXX_3.4 00000000 A GLIBCXX_3.4.1 00000000 A GLIBCXX_3.4.2 00000000 A GLIBCXX_3.4.3 00000000 A GLIBCXX_3.4.4 00000000 A GLIBCXX_3.4.5 00000000 A GLIBCXX_3.4.6 00000000 A GLIBCXX_3.4.7 00000000 A GLIBCXX_3.4.8 nao@nao ~ $ nm -D /usr/lib/gcc/i686-pc-linux-gnu/4.2.2/libstdc++.so.6 | grep GLIBCXX 00000000 A GLIBCXX_3.4 00000000 A GLIBCXX_3.4.1 00000000 A GLIBCXX_3.4.2 00000000 A GLIBCXX_3.4.3 00000000 A GLIBCXX_3.4.4 00000000 A GLIBCXX_3.4.5 00000000 A GLIBCXX_3.4.6 00000000 A GLIBCXX_3.4.7 00000000 A GLIBCXX_3.4.8 00000000 A GLIBCXX_3.4.9 -------------------------------- GLIBCXX_3.4.9 is only in 4.2.2, but not in 4.1.2 version of libstdc++.so Thats a problem. (I`m not a programmer and I`m only know that it named "symbols") Sorry for my bad english:( Reproducible: Always Steps to Reproduce: 1. emerge sys-devel/gcc-4.2.2 and compile all packages with it 2. emerge sys-devel/gcc-4.1.2 and select it as default compiler with gcc-config 3. try running some applications like nmap, amarok, cmake and many others Actual Results: binaryname: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by binaryname) Expected Results: Maybe there must be some kind of script that fixes this bug (like fix_libtool_files.sh) or this must be integrated in revdep-rebuild command for finding and remerging broken packages $ find /bin /sbin /usr/bin /usr/sbin | while read FILE; do readelf -V $FILE

guess you shouldnt have done that
Created attachment 178424 [details] This script should help to find such packages I wrote this script to help find such broken packages. Steal some code from revdep-rebuild;)
