Hi, sorry for late answer, but yes, the libpthread-files exists in my customized sandbox sysroot (as well as in the ‘clean’ sandbox sysroot). The (autotooled) project that I’m build is trying to link an application and it uses CXXLD (which is CXX => arm-poky-linux-gnuabi-g++). LD has the –sysroot flag appended in the command, CXXLD doesn’t have it (according to the generated Makefile). Am I or autotools doing something wrong here?
