• -l "digilent.waveforms_3.7.5_i386/usr/lib" should be -L"digilent.waveforms_3.7.5_i386/usr/lib"
• does "digilent.waveforms_3.7.5_i386/usr/lib" contain a file called dwf.lib or dwf.a (sorry I don't remember the estension of gcc libraries)?
• You probably have to do the same for -lfftw3

  changes made,but again same error

  yes, It has file dwf.h
  will that okay bro?

• You probably have to do the same for -lfftw3
  -lfftw3 working fine bro

[VRonin]

@thippu said in oscilloscope in qt:

yes, It has file dwf.h

Nope. it must be a compiled binary, not a header

[thippu]

@VRonin Bro Is libdwf.so are complied binary?

[VRonin]

yes so you have to change -ldwf to -llibdwf also

[aha_1980]

@VRonin

yes so you have to change -ldwf to -llibdwf also

Nope. If you want to link against library libxyz.so, the linker line is `-lxyz'.

Example: the math library libm.so is linked with -lm.

Don't ask me who invented this...

@aha_1980 , @VRonin , @SGaist Guys thank you!
Whatever u said I did,I'm sorry to say this,Not executing still.
Idk what do,paths are working,lib exists, but not executing why?! :(
If you try this on u r machine letme know if it works link:

@thippu

so what is your exact problem? is it a compiler/linker error: then please post the error.

otherwise do a ldd <program> to list the dependencies (replace <program> with the final executables name) and post that.
