Hi everyone,I'm running an F_AMIP_CAM5 case with modified source code.I put the modified files: cam_diagnostics.F90, physics_types.F90, physpkg.F90, into src.cam, and cleaned the build. But when i rebuilt the case, it showed that cam.buildexe.csh failed. The following is the detailed bldlog file.The thing is the errored lines showed below are exactly the same as its orignal ones, and are not changed at all. ***************************************/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2581): error #6236: A specification statement cannot appear in the executable section. use perf_mod--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2583): error #6236: A specification statement cannot appear in the executable section. use prescribed_ozone, only: prescribed_ozone_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2584): error #6236: A specification statement cannot appear in the executable section. use prescribed_ghg, only: prescribed_ghg_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2585): error #6236: A specification statement cannot appear in the executable section. use prescribed_aero, only: prescribed_aero_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2586): error #6236: A specification statement cannot appear in the executable section. use aerodep_flx, only: aerodep_flx_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2587): error #6236: A specification statement cannot appear in the executable section. use aircraft_emit, only: aircraft_emit_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2588): error #6236: A specification statement cannot appear in the executable section. use prescribed_volcaero, only: prescribed_volcaero_adv--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2591): error #6236: A specification statement cannot appear in the executable section. implicit none--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2593): error #6236: A specification statement cannot appear in the executable section. type(physics_state), intent(inout), dimension(begchunk:endchunk) :: phys_state--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2594): error #6236: A specification statement cannot appear in the executable section. type(cam_out_t), intent(inout), dimension(begchunk:endchunk) :: cam_out--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(2596): error #6236: A specification statement cannot appear in the executable section. type(physics_buffer_desc), pointer :: pbuf2d(:,:)--^/general/home/baisy/Amazon_1850PDC5_src/SourceMods/src.cam/physpkg.F90(78): error #6404: This name does not have a type, and must have an explicit type.
