--- Comment #12 from christophe.lyon at st dot com 2010-11-22 10:06:07 UTC --- Yes, I appreciate your help very much (and I spent quite some time investigating on my own before deciding to bother you). Now, I am sorry to insist, but it's still unclear to me why GCC and G++ behave differently, and why there is a link script rather than a fix in the driver. I have compile & link the code attached as atomic.cxx in C mode, I can see some differences wrt the case where I do the same thing with G++ (invoking with -v): - g++ has -shared-libgcc in COLLECT_GCC_OPTIONS - g++ links with lstdc++ -lm -lgcc_s -lc -lgcc_s - gcc links with -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed So, the very same code, when compiled & linked in C mode, is linked against -lgcc, but not in C++ mode; that's why I proposed a changed in the driver (to adjust the specs for -shared-libgcc)
