Does installing gcc47 package on SLE_11 SP2 change the default compiler?

I’ve added the gcc development repo as described on this project page. The dependency check fails as follows:

sudo zypper install gcc47

Resolving package dependencies…

Problem: gcc47-4.7.3_20130411-89.1.x86_64 requires libgcc_s1 >= 4.7.3_20130411-89.1, but this requirement cannot be provided
uninstallable providers: libgcc_s1-4.7.3_20130411-89.1.x86_64[devel_gcc]
Solution 1: deinstallation of libgcc46-4.6.1_20110701-0.13.9.x86_64
Solution 2: do not install gcc47-4.7.3_20130411-89.1.x86_64
Solution 3: do not install gcc47-4.7.3_20130411-89.1.x86_64
Solution 4: break gcc47 by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/3/4/c] (c): c

where I elected to cancel. I’m a bit nervous about replacing libgcc-anything. Does this package prevent me from, say, compiling a kernal object?


This is the wrong forum for SLE, it’s over at same login name etc :wink:

Can’t remember if gcc47 is on the SP2 SDK, SP3 has gcc47 available on the SDK, can you update the system?
