Error using MEX #11

Open MiguelVSantos opened 6 years ago

MiguelVSantos commented 6 years ago

Hi, I've tried to compile but afeter i added the empty libhackrf.lib file i get this error:

C:\hackrf_one\simulink-hackrf-1.0\simulink-hackrf-1.0\deps\bin\libhackrf.lib: file not recognized: File truncated collect2.exe: error: ld returned 1 exit status

Error in make (line 66) mex(options{:}, 'src/hackrf_find_devices.c')

btw i'm using MATLAB R2018a any idea? regards

Hey, I had the same issue with MATLAB R2017B. The file libhackrf.lib cannot be empty, since MATLAB use it for compiling with MEX. I found a way to easily create a valid libhackrf.lib file using Microsoft Visual C++ ("MSVC"):

  1. Call a new MSVC console (e.g. for "Visual Studio 2019": Start a new command line window and call the batch-script from "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community \VC\Auxiliary\Build\vcvars64.bat")

  2. Change directory to "deps\bin\" and run: dumpbin /EXPORTS libhackrf.dll > libhackrf.exports

  3. Create a new file called "libhackrf.def" and insert the following lines:

    LIBRARY "libhackrf.dll"
EXPORTS
hackrf_board_id_name
hackrf_xxx

    ... for _hackrfxxx insert each "hackrf_" element from your previously created "libhackrf.exports" file

  4. In your MSVC console type the command: lib /def:libhackrf.def /machine:x64 /out:libhackrf.lib

  5. If you now run make in MATLAB it should compile without any problems
