1.2.9 Rebuilding the DSP Library
To build the DSP library, extract the source files in the (Compiler Install Path)\src\libdsp.zip path; this creates a sub-folder called libdsp. Execute the makedsplib.bat file within this folder to rebuild the library archives. This creates two folders called "lib" and "obj". Once the batch file execution is completed, the rebuild libdsp.a file can be found in the “lib” folder.
The MPLAB XC32 compiler is required to rebuild the DSP library, and its installation path must be added to Windows® or Linux® environment variables.
