The above link hints that there is a change in the ABI starting GCC 5.x. The new default ABI for libstd++ is C++11/14... which is not compatible with the older ABI. There is a way to select the older ABI using a define. I am trying to understand what is the difference between the ABIs and haven't found details. I'd like help understanding: What kind of issues with std::string need to be fixed to be

Basically I would like to know the difference between ARMv7l and ARMv7 h l? I got a arm processor with armv7l and there are a lot of rpm's for armv7 h l. I don't exactly know what I have to search for to get information about that. What is this "suffix" called? Are there any other types? What are they doing differently? I would assume that it's indicating packages compiled for l ittle-endian and h ard-float ABI as appropriate - i.e. it's a software thing and only tangentially related to the hardware. In other words, you don't actually have an "armv7l" processor - you have an ARMv7 processor

To be noted that I know the difference between the 2 hardware coprocessor units(as also outlined here on SO ), I just have some misunderstanding regarding their proper usage. Related to this I'm using the following compilation flags: GCC -O3 -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=softfp -O3 -mcpu=cortex-a9 -mfpu=vfpv3

And When I installed boost, it seems that it used the new ABI but then I get the following link errors undefined symbol.....__cxx11.... How can I install boost using old ABI with GCC5 ? 回答1: To my knowledge, there are no prebuilt Boost packages for the old ABI in the official Kubuntu repositories, so you will have to build Boost yourself. The building process is documented here . Make sure you're

I get following error elf file OS ABI invalid Can anybody please pass my any pointer helpful in resolving this issue.Please note that my kernel version is linux-2.6.35.9 回答1: It's not your kernel version that's the problem. The loader on your system does not support the new Linux ABI. Until relatively recently, Linux ELF binaries used the System V ABI. Recently, in support of STT_GNU_IFUNC, the Linux ABI was added. You would have to update your

It seems Clang is not aware of the GCC inline namespace changes , so it generates code based on one set of namespaces or symbols, while GCC used another set of namespaces or symbols. At link time, there are problems due to missing symbols. If I am parsing the Dual ABI page correctly, it looks like a matter of pivoting on _GLIBCXX_USE_CXX11_ABI and abi::cxx11 with some additional hardships. More reading is available on Red Hat's blog at GCC5 and the C++11 ABI and The

I tried to google it, but all I find is the GCC source code line that prints the note string. 回答1: Pass the option -Wno-psabi to GCC. 回答2: I was getting the same message: /usr/include/c++/4.8.3/bits/stl_pair.h:276:5: note: the ABI of passing structure with complex float member has changed in GCC 4.4 for the
