--- Comment #16 from AlexK <alexei_sylver1 at mail dot ru> --- I have copied already compileed shared libs into new directories: cp -v prev-libcpp/libcpp.so libcpp/ cp -v prev-libbacktrace/libbacktrace.so libbacktrace/ cp -v prev-libdecnumber/libdecnumber.so libdecnumber/ and continue: make Configuring stage 2 in ./gcc configure: loading cache ./config.cache checking
