Special Usage Description

If both the KVSIP and open-source VSIP need to be used, dynamically link the VSIP.

To compile the VSIP dynamic library, perform the following steps:

1. Download the open source VSIP library.

   Download URL: https://github.com/rrjudd/jvsip

2. Modify the c_VSIP_src/Makefile file.
   1. Open c_VSIP_src/Makefile.

      vi c_VSIP_src/Makefile

   2. Change the value of CFLAGS, delete the -arch x86_64 parameter that specifies x86, and add the -fPIC option.

      CFLAGS= -O3 -Wall -std=c89 -pedantic -fPIC

   3. Add the following content to line 13:

      gcc --shared $(OBJECTS) -o libvsip.so

      

   4. Press Esc, type :wq!, and press Enter to save the file and exit.
3. Modify Makefile.
   1. Open Makefile.

      vi Makefile

   2. Change the value of CFLAGS and add the -fPIC option.

      CFLAGS=-O3 -Wall -std=gnu99 -pedantic -fPIC

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
4. Generate a dynamic library libvsip.so in the c_VSIP_src directory.

   make

5. Replace the Huawei-developed vsip.h file with the open source vsip.h file.

   cp -rf ./c_VSIP_src/vsip.h /usr/local/include/KVSIP/

When calling this function library, you need to add the following compilation options:

gcc test.c -o test -I /usr/local/include/KVSIP/ -L /usr/local/lib/KVSIP/ -lkvsip_fft -lkvsip_fftf -lkvsip -lm -fPIC -L ./c_VSIP_src -lvsip -Wl,-rpath=./c_VSIP_src
