The problem seems to be that some code may be built as C++ and not C, which may explain the linker error. On this thread reply: https://sourceware.org/ml/gdb/2016-11/msg00045.html it mentions that the simulator should not call GDB's "error" function directly, but rather use the "host_callback" struct. I have no idea about the use of the GDB simulator within the OpenWrt/LEDE community. So, I took the easier route, which is to disable the simulator. (Also suggested here: https://sourceware.org/ml/gdb/2016-11/msg00047.html ) If needed, I can make an effort to fix the simulator for PPC. Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>
This is the buildsystem for the LEDE Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your LEDE Community http://www.lede-project.org
