Seems to be working now, I am using this binutils-gold package though: 2.20.1-3, not the one from experimental. I commented out this line in debian/rules.defs # FIXME: stripping doesn't work with gold #with_gold := no I disabled the testsuite too (was taking way too long): # if you don't want to run the gcc testsuite, uncomment the next line with_check := disabled by hand Also I had some trouble with building the doc packages, so I just did a 'touch stamps/05-build-javadoc-stamp', didn't figure out how to turn off the build of the docs package completely. I installed these debs: ii cpp-4.5 4.5-20100321-1 The GNU C preprocessor ii gcc-4.5 4.5-20100321-1 The GNU C compiler ii gcc-4.5-base 4.5-20100321-1 The GNU Compiler Collection (base package) ii gcc-4.5-multilib 4.5-20100321-1 The GNU C compiler (multilib files) ii lib32gcc1 1:4.5-20100321-1 GCC support library (32 bit Version) ii lib32gomp1 4.5-20100321-1 GCC OpenMP (GOMP) support library (32bit) ii libgcc1 1:4.5-20100321-1 GCC support library ii libgomp1 4.5-20100321-1 GCC OpenMP (GOMP) support library ii libstdc++6 4.5-20100321-1 The GNU Standard C++ Library v3 apt-cache and everything else still seems to be working. I found the LTO plugin here (it was not installed by the package) ./debian/tmp/usr/lib/gcc/x86_64-linux-gnu/4.5/liblto_plugin.so So I copied it to /usr/lib/gcc/x86_64-linux-gnu/4.5/liblto_plugin.so manally, and -fuse-linker-plugin seems to be working now (well I get an ICE from it when trying to build ClamAV, will open a bug about that shortly). Can you please make the package install liblto_plugin.so when with_gold is yes? > If you retry, please > report the results in this report. I'm not sure I understand what 'this' refers to here (#575448 or #571169), so I'll just report it here.
