[M3devel] compile problem on LINUXLIBC6

[Daniel Alejandro Benavides D.]

Hi all:
I wonder why it's making libcpp, does it some tool use it? just for c this days? anyway it would be good if you can test it just with another compiler version, perhaps the clash is product of incompability of version 4.50, 4.5.1 -><- perhaps you can try to build the gcc trunk to see how it builds, if it builds then you have a problem of compability in your gcc headers, This is why is this C code is sort of not portable, you don't know when you get a compiler error after thinking it is OK.
Then if so, try to use gcc trunk instead to build in your cm3 building.
Thanks in advance
