Hello all, I am attempting to build a C/C++ cross compiler that runs on x86_64-pc-linux-gnu and targets arm-unknown-linux-gnueabihf. I am not building libc so I am building GCC using --with-sysroot to point to the root file system of the target. I am building GCC v6.2.0 and binutils 2.27. The produced cross compiler is capable of compiling C but it fails when building C++ code in a very odd manner. If I build C++ code using purely static libraries it also works. Building C++ without -static, however results in the errors below. What's odd is that the multiple definition errors in the dynamic libstdc++.so are from symbols in the same library. Any ideas as to what what may be causing this? Thanks, Mark. /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so:(*IND*+0x0): multiple definition of `ldexpl@GLIBCXX_3.4.3' /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so::(.text+0x1930): first defined here /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so:(*IND*+0x0): multiple definition of `frexpl@GLIBCXX_3.4.3' /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so::(.text+0x1928): first defined here /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so: In function `modfl@GLIBCXX_3.4.3': :(.text+0x193c): multiple definition of `modfl@GLIBCXX_3.4.3' /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so:(*IND*+0x0): multiple definition of `modfl' /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/bin/ld:
