There are two headers in the client directory, sim.h and client_state.h, which would declare that symbol, but neither seems to get included. As I was building with the cuda USE flag unset, I'm a bit surprised to find a symbol referring to cuda gets used, but I haven't dug into this.

Post complete build.log please.
Btw it should build cuda support everytime, it does not have any configure option or deps. Also in these files cuda is mentioned: scarab@arcarius: ~/tmp/boinc-6.6.40 $ find ./ -name \*.h |while read file; do > [[ `cat ${file} |grep cuda |wc -l` -gt 0 ]] && echo ${file} > done ./client/client_types.h ./client/client_state.h ./client/work_fetch.h ./client/sim.h ./lib/gui_rpc_client.h ./lib/coproc.h ./sched/server_types.h ./sched/sched_config.h scarab@arcarius: ~/tmp/boinc-6.6.40 $ find ./ -name \*.cpp |while read file; do [[ `cat ${file} |grep cuda |wc -l` -gt 0 ]] && echo ${file}; done ./client/client_types.cpp ./client/sim.cpp ./client/work_fetch.cpp ./client/cs_scheduler.cpp ./client/app_start.cpp ./client/app.cpp ./client/cpu_sched.cpp ./client/rr_sim.cpp ./client/scheduler_op.cpp ./client/gui_rpc_server_ops.cpp ./client/client_state.cpp ./client/cs_statefile.cpp ./lib/gui_rpc_client_ops.cpp ./lib/coproc.cpp ./clientgui/AsyncRPC.cpp ./clientgui/DlgItemProperties.cpp ./sched/sched_plan.cpp ./sched/sched_config.cpp ./sched/handle_request.cpp ./sched/sched_send.cpp

(In reply to comment #2) > Btw it should build cuda support everytime, it does not have any configure > option or deps. I see, so it's a runtime thing only. > scarab@arcarius: ~/tmp/boinc-6.6.40 $ find ./ -name \*.h |while read file; do > > [[ `cat ${file} |grep cuda |wc -l` -gt 0 ]] && echo ${file} > > done I'd have written this simply as "find . -name \*.h | xargs grep -l cuda", but I'll have to agree this is a bit off topic... I take it the build does succeed for you. Can you compile boinc and then take the g++ command used to compile handle_request.cpp, change "-c" to "-E" and "-o handle_request.o" to "-o handle_request.pp.cpp", and run the resulting command manually? That should give us the preprocessed form of the handle_request.cpp file on a system where it does compile. We could look at this to see if coproc_cuda gets delcared, and if so, determine the chain of include files that lead to this declaration. If it doesn't get included, I assume my compiler is more strict than yours, and determining the reason might prove valuable.
