Dear All, I'm a new user of this mailing list. I've this problem. I had an old gcc version on my laptop so I downloaded the 4.1 and I installed it using the following commands: configure --enable-shared --with-gnu-as --with-gnu-ld --enable-languages=c,c++ make bootstrap make install everything worked, but now when I have to install some software and when I run the configure file of this software, I obtain the following error during the configure phase: configure:2348: checking for C++ compiler default output file name configure:2375: g++ conftest.cpp >&5 /usr/local/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../libstdc++.so: undefined reference to `___tls_get_addr' collect2: ld returned 1 exit status Please, can u help me?? Thanks a lot for your time Marco Turchi
