Hello evrybody, I need to upgrade my gcc to gcc4.4. I use to compile my C++ file with gcc4.3.2 that comes with mandriva 2009 (I did not install it alone). I try upgrade using # apt-get install gcc the result is : Reading Package Lists... Done Building Dependency Tree... Done gcc is already the newest version. 0 upgraded, 0 newly installed, 0 removed and 0 not upgraded. although the used gcc is not the newest version: # rpm -qi gcc Name : gcc Relocations: (not relocatable) Version : 4.3.2 Vendor: Mandriva Release : 3.1mnb2 Build Date: mar. 24 nov. 2009 19:15:09 CET Install Date: jeu. 17 déc. 2009 13:48:59 CET Build Host: titan.mandriva.com Group : Development/C Source RPM: gcc-4.3.2-3.1mnb2.src.rpm Size : 12600797 License: GPLv3+ Packager : Mandriva Linux Security Team <security@xxxxxxxxxxxx> URL : http://gcc.gnu.org/ ..... I download the gcc-4.4.2-5mnb2.i586.rpm to install it but I can not: some packages are not satisfied: gcc-cc[==4.4.2_5mnb2] do not satisfy. This rpm is available for mandriva 2010. the question is, can I install gcc4.4 in my mandriva 2009 ? If yes, How can I upgrade gcc without performing all long instructions of gcc installation explained here http://gcc.gnu.org/install/index.html If I am obliged to reinstall gcc, which is better, installing it from svn sources or from mirrors (I have downloded both files) ? How can I find if GMP, MPFR or MPC are installed or not in my library search path? (which command to use ) Thank you very much Asma
