can't simulate with latest trunk

can't simulate with latest trunk

Sep-28-12 04:18:33

I installed the latest mmc, then did a make clean and make in OpenModelica.  I got a working OMedit, but it can't simulate:

Code:

mmc_jumper is present in libSimulationRuntimeC.a, so it must be some linking issue I'm not seeing here.

Code:


% nm /Users/wjanssen/Desktop/OMedit.app/Contents/Resources/lib/omc/libSimulationRuntimeC.a | grep mmc_jumper

                 U _mmc_jumper

nm: no name list

                 U _mmc_jumper

0000000000000008 C _mmc_jumper

                 U _mmc_jumper

The only difference I can see from the linux version is that the symbols are prefixed "_" in OSX. Of course everything works in Linux and nothing in OSX.

Ok, I figured out how to solve it. Simply run:

Code:

ld -o OSXUGLYHACK.o -r util/omc_error.o ./meta/meta_modelica_builtin.o ./meta/meta_modelica_string_lit.o ./meta/realString.o ./meta/meta_modelica_real.o ./meta/gc/gc.o ./meta/gc/common.o ./meta/gc/roots.o ./meta/gc/generational.o ./meta/gc/marksweep.o ./util/base_array.o ./util/boolean_array.o ./util/division.o ./util/index_spec.o ./util/integer_array.o ./util/java_interface.o ./util/list.o ./util/memory_pool.o ./util/modelica_string.o ./util/modelinfo.o ./util/read_write.o ./util/read_matlab4.o ./util/real_array.o ./util/ringbuffer.o ./util/rtclock.o ./util/string_array.o ./util/utility.o ./util/varinfo.o ./math-support/bigden.o ./math-support/biglag.o ./math-support/dgesv_aux.o ./math-support/dogleg.o ./math-support/dpmpar.o ./math-support/enorm.o ./math-support/fdjac1.o ./math-support/hybrd.o ./math-support/hybrd1.o ./math-support/hybrj.o ./math-support/lsame.o ./math-support/nelmead.o ./math-support/newuoa.o ./math-support/newuob.o ./math-support/nonlinearSystem.o ./math-support/nonlinearSolverHybrd.o ./math-support/qform.o ./math-support/qrfac.o ./math-support/r1mpyq.o ./math-support/r1updt.o ./math-support/trsapp.o ./math-support/update.o ./simulation/solver/daux.o ./simulation/solver/ddasrt.o ./simulation/solver/ddassl.o ./simulation/solver/dassl.o ./simulation/solver/delay.o ./simulation/solver/dlamch.o ./simulation/solver/dlinpk.o ./simulation/solver/events.o ./simulation/solver/initialization.o ./simulation/solver/initialization_data.o ./simulation/solver/ipopt_initialization.o ./simulation/solver/model_help.o ./simulation/solver/solver_main.o ./simulation/solver/kinsol_initialization.o ./simulation/solver/newuoa_initialization.o ./simulation/solver/simplex_initialization.o ./simulation/solver/nelderMeadEx_initialization.o ./simulation/results/read_csv.o ./simulation/results/simulation_result_csv.o ./simulation/results/simulation_result_mat.o ./simulation/results/simulation_result_plt.o ./simulation/options.o ./simulation/simulation_input_xml.o ./simulation/simulation_runtime.o ./simulation/../linearization/linearize.o meta/meta_modelica_catch.o meta/meta_modelica.o

Followed by:

Code:

ar -ru libSimulationRuntimeC.a OSXUGLYHACK

This makes the linker suddenly find the symbols. Stupid OSX linkers. Now to see if I can do this without breaking the other tools...

Try https://trac.openmodelica.org/OpenModel … eset/13088
And please add bug reports to the trac in the future current/wink

Wasn't sure it was a bug -- thought probably just me doing something stupid :-).   Will do, in the future.
