branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Matplotlib contains .cpp source code:
ls src/*.cpp
src/_backend_agg.cpp
src/_backend_agg_wrapper.cpp
src/_contour.cpp
src/_contour_wrapper.cpp
src/ft2font.cpp
src/ft2font_wrapper.cpp
src/_image.cpp
src/_image_wrapper.cpp
src/mplutils.cpp
src/_path_wrapper.cpp
src/_png.cpp
src/py_converters.cpp
src/_tkagg.cpp
src/_ttconv.cpp
src/_windowing.cpp
So add a dependency on C++ support in the toolchain to fix build errors like
(no autobuilder reference yet):
../output/host/bin/powerpc-buildroot-linux-uclibc-gcc -Wno-unused-result \
-Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -D_LARGEFILE_SOURCE \
-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -fPIC \
