safe_malloc build error in user_spray_udf
Hi all
In user_spray_udf there are a couple of lines for memory allocation that keeps making build error. those lines are: /// islam memory allocation check for a bug vapor_mass_0=(double *)safe_malloc(num_parcel_species*sizeof(double)); vapor_mass=(double *)safe_malloc(num_parcel_species*sizeof(double)); local_species=(double *)safe_malloc(num_total_species*sizeof(double)); temp_boil=(PRECISION *)safe_malloc(num_parcel_species*sizeof(double)); The build error is: Undefined symbols for architecture x86_64: "safe_malloc(unsigned long)", referenced from: user_spray_evap_cell(parcel_cell_definition*, double*, double*) in main.cpp.o My solution was to swap "safe_malloc" with "malloc" and it worked. is there another solution like adding a function in header files ?? Thanks in advance |
Hi Kabil,
Make sure that you had taken care of the following : 1) All the header files are there in the UDF directory. Especially in your case, it looks like safe_prototypes.h might be missing. 2) user_dynamic_routines.c is there in the UDF directory. 3) The makefile for UDF refer to the respective object files for the C-routines you are compiling. I am guessing one of the above is not taken care of, which leads to build error message. If that is not the case, please send your files to support@convergecfd.com to have a closer look at this.
