Hi,
I have recently been getting the following linker error on some builds of the ET:
/home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_e055fb02a4c17556fd41c009e44c5f0671d21e6e/lib/libthorn_CactusBindings.a(ScheduleGRHydro_InitData.c.o): In function `CCTKi_BindingsSchedule_GRHydro_InitData': /home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_e055fb02a4c17556fd41c009e44c5f0671d21e6e/bindings/Schedule/ScheduleGRHydro_InitData.c:185: undefined reference to `grhydro_cylindricalexplosionm_' make[1]: *** [/home/ianhin/Cactus/EinsteinToolkitTests/exe/cactus_einsteintoolkit_e055fb02a4c17556fd41c009e44c5f0671d21e6e] Error 1 make: *** [einsteintoolkit_e055fb02a4c17556fd41c009e44c5f0671d21e6e] Error 2
It is reproducible, in the sense that I can run the build command again on the same configuration without cleaning it, and get the same error. But when a new configuration is built, the error goes away or changes. I first saw this a few days ago, and have never seen it before.
The first time I saw it, the error was with one of the bindings files:
16039 /home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d/lib/libthorn_CactusBindings.a(BindingsSchedule.c.o): In function `CCTKi_BindingsScheduleInitialise': 16040 /home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d/bindings/Schedule/BindingsSchedule.c:440: undefined reference to `CCTKi_BindingsSchedule_Hydro_InitExcision' 16041 /home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d/lib/libthorn_CactusBindings.a(BindingsParameterRecovery.c.o): In function `CCTKi_BindingsParameterRecoveryInitialise': 16042 /home/ianhin/Cactus/EinsteinToolkitTests/configs/einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d/bindings/Schedule/BindingsParameterRecovery.c:689: undefined reference to `CCTKi_BindingsParameterRecovery_Hydro_InitExcision' 16043 make[1]: *** [/home/ianhin/Cactus/EinsteinToolkitTests/exe/cactus_einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d] Error 1 16044 make: *** [einsteintoolkit_63b457e6e6391de8061e1fd96b7cac0c1d8a775d] Error 2
The only thing in common is that the problem always seems to arise with GRHydro, but this might be a coincidence.
Looking back in the build log for the first case, I see:
13013 COMPILING /home/ianhin/Cactus/EinsteinToolkitTests/arrangements/EinsteinInitialData/GRHydro_InitData/src/GRHydro_CylindricalExplosionM.F90 13014 : remark #5133: The input stream is empty
If this file were in fact empty, the linker error is what I would expect. But the file does not seem to be empty, it does in fact contain the subroutine GRHydro_cylindricalexplosionM.
The output files in the config directory seem to be OK:

Does anyone have an idea of why this might have started happening?
