We never pass -lgcc to linker when building C++ DSO: /usr/libexec/gcc/x86_64-redhat-linux/4.9.2/collect2 -plugin /usr/libexec/gcc/x86_64-redhat-linux/4.9.2/liblto_plugin.so -plugin-opt=/usr/libexec/gcc/x86_64-redhat-linux/4.9.2/lto-wrapper -plugin-opt=-fresolution=/tmp/ccZC7iqy.res -plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc_s --build-id --no-add-needed --eh-frame-hdr --hash-style=gnu -m elf_x86_64 -shared /usr/lib/gcc/x86_64-redhat-linux/4.9.2/../../../../lib64/crti.o /usr/lib/gcc/x86_64-redhat-linux/4.9.2/crtbeginS.o -L/usr/lib/gcc/x86_64-redhat-linux/4.9.2 -L/usr/lib/gcc/x86_64-redhat-linux/4.9.2/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib/gcc/x86_64-redhat-linux/4.9.2/../../.. x.o -lstdc++ -lm -lgcc_s -lc -lgcc_s /usr/lib/gcc/x86_64-redhat-linux/4.9.2/crtendS.o /usr/lib/gcc/x86_64-redhat-linux/4.9.2/../../../../lib64/crtn.o [hjl@gnu-32 tmp]$ That is why libgcc_nonshared.a is needed. -- H.J.
