In sdcc from current trunk, build fails for me sporadically (about once for every 10 times i try to compile) when using make -j 18.

As far as I can see the build fails in the m6800 part of uCsim. I suspect some race condition in the build system.

I have attached the output from make -j18 &> buildfaillog

    Dear Philipp,
    [r12444] solved this for me, but I still investigate.

      I noticed it in the callingconvention branch (since I want to build that one about 500 times per night for some experiments).
      The current [r12448] callingconvention branch has all the changes from [r12447] noasm2 branch, which in turn has all the changes from trunk [r12446]. So trunk would still have the same problem (though I'm not building trunk often enough to have encountered the problem since).

    Philipp, which is the way you call the configure script?

    I think [r12444] breaks builds that are outside of the source tree, which is causing all the snapshot builds to fail. But this is also how I normally build locally too. In my case "sdcc-main2" is my source directory and "sdcc-build2" is my build directory:

    make -C m68hc12.src m68hc12.src

    Here the "make -C ../../../../sdcc-main2/sim/ucsim/m6800.src all" fails because that directory has no Makefile, only Makefile.in

    It builds okay if I edit packages.mk to disable m68hc12

    Fix is in [r12456].

      I still see sporadic build failures, still in the m6800 part, even though the error message looks a little different now. Output from

      make -j 18 &> log

      I attached.

        I suspect that these lines fromt eh above file 

        g++ -g -O2 -g -Wall  simm6800.o m6800.o glob.o irq.o inst.o ialu.o ibranch.o imove.o sm6800.o -L.. -lmotorola -lsim -lucsimutil -lguiucsim -lcmd -lsim -lrt -lnsl  -o sm6800
ranlib ../libm6800.a
yes
/usr/bin/ld: simm6800.o: in function `cl_simm6800::mk_controller()':
/home/philipp/callingconvention/experiments-stm8/sdcc_args___ret_xl_x_xy_callee/sim/ucsim/m6800.src/simm6800.cc:40: undefined reference to `cl_m6800::cl_m6800(cl_sim*)'
collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:124: sm6800] Fehler 1

        Are close to the underlying issue: Apparentlythe time sm6800 is to be linked whatever is supposed to contain cl_m6800::cl_m6800(cl_sim*) is not there yet.

        P.S.:

        Also, I see these two lines

        ranlib ../libm6800.a
g++ -g -O2 -g -Wall  simm6800.o m6800.o glob.o irq.o inst.o ialu.o ibranch.o imove.o sm6800.o -L.. -lmotorola -lsim -lucsimutil -lguiucsim -lcmd -lsim -lrt -lnsl  -o sm6800

        twice in the log output, which seems odd to me. Does the build infrastructure build the same files twice, possibly even attempting to do so at the same time?

    I can no longer reproduce this issue in current trunk.
