cvAdvDiff_bnd_README.md

This example was compiled by doing:

1. Compile the libraries:

   gcc -c src/sundials/sundials_math.c -Iinclude 
   gcc -c src/sundials/sundials_band.c -Iinclude 
   

   This generates the .o files (the -c flag compiles but does not link)

2. Compile the example file:

   gcc -Wall -c cvAdvDiff_bnd.c -o test.o -Iinclude -L$LD_LIBRARY_PATH -lm -lsundials_cvodes -lsundials_ida -lsundials_kinsol -lsundials_nvecserial
   

   This generates the test.o file

3. Now link all the .o files including the libraries and headers:

   gcc -Wall test.o sundials_math.o sundials_band.o -o test -Iinclude -L$LD_LIBRARY_PATH -lm -lsundials_cvodes -lsundials_ida -lsundials_kinsol -lsundials_nvecserial
   

4. Execute the test: ./test

Notes

We can create the shared libraries:

gcc -shared -o libsundials_math.so sundials_math.o
gcc -shared -o libsundials_band.so sundials_band.o

And then use the libraries to directly compile the example C file:

gcc -Wall cvAdvDiff_bnd.c -o test -L/home/david/tmp/cvode -lsundials_math -lsundials_band -L$LD_LIBRARY_PATH -lm -lsundials_cvodes -lsundials_ida -lsundials_kinsol -lsundials_nvecserial -Iinclude

Somehow, order matters. The sundials_* libraries must be called before the ones from LD_LIBRARY_PATH
