Hi experts，
I need to connect Basler's camera via USB3.0 on the J7 EVM board. Basler provides the driver for the camera. I use the compiler gcc-arm-9.2-2019.12-x86_64-aarch64-none-linuk-gnu provided by TI. QT5.14.2 has been cross-compiled. In the camera test program, I added the camera library and reported the following error:
Qt is looking for glibc in the aarch64 directory, where the version of the library does not support GLIBCXX_3.4.21. Please help to see why the version of glibc in gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu can only support glibc2.18 at most. I downloaded the latest compiler from arm website（gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu.tar.xz）, which supports glibcxx_3.4.28, I found that libstdc++.so.6 of gcc-arm-9.2 and gcc-arm-10.2 both point to libstdc++.so.6.0.28 library. Why use the same library and support different versions of glibcxx and cxxabi? I can't support using the latest compiler right now, because I need other Ti libraries in my project. I would like to ask, what can solve the problem that gcc-arm-9.2 version can support glibcxx_3.4.28 and cxxabi_1.3.10, any help would be appreciated, thank you!
