[Discuss-gnuradio] GSL_FOUND both TRUE and FALSE

[Achilleas Anastasopoulos]

Hi all,

after a long time update from source on a Fedora 23 I came across the following problem when cmaking:

-- Configuring gr-fec support...

--   Dependency ENABLE_VOLK = ON

--   Dependency Boost_FOUND = 1

--   Dependency ENABLE_GNURADIO_RUNTIME = ON

--   Dependency ENABLE_GR_BLOCKS = ON

--   Dependency GSL_FOUND = TRUE         <============================

--   Enabling gr-fec support.

--   Override with -DENABLE_GR_FEC=ON/OFF

-- Checking for module 'fftw3f >= 3.0'

--   Found fftw3f , version 3.3.4

-- Found FFTW3F: /lib64/libfftw3f.so

but then 

-- Configuring gr-dtv support...

--   Dependency Boost_FOUND = 1

--   Dependency GSL_FOUND = FALSE  <============================

--   Dependency ENABLE_GNURADIO_RUNTIME = ON

--   Dependency ENABLE_GR_ANALOG = ON

--   Dependency ENABLE_GR_FILTER = ON

--   Dependency ENABLE_GR_FEC = ON

--   Disabling gr-dtv support.

--   Override with -DENABLE_GR_DTV=ON/OFF

-- Could NOT find GSL (missing:  GSL_INCLUDE_DIRS GSL_LIBRARY_DIRS) 

--

-- Configuring gr-atsc support...

--   Dependency Boost_FOUND = 1

--   Dependency GSL_FOUND = FALSE   <============================

--   Dependency ENABLE_GNURADIO_RUNTIME = ON

--   Dependency ENABLE_GR_FFT = ON

--   Dependency ENABLE_GR_BLOCKS = ON

--   Dependency ENABLE_GR_FEC = ON

--   Dependency ENABLE_GR_FILTER = ON

--   Dependency ENABLE_GR_ANALOG = ON

--   Disabling gr-atsc support.

--   Override with -DENABLE_GR_ATSC=ON/OFF

--

-- Configuring gr-wavelet support...

--   Dependency Boost_FOUND = 1

--   Dependency ENABLE_GNURADIO_RUNTIME = ON

--   Dependency ENABLE_GR_BLOCKS = ON

--   Dependency ENABLE_GR_ANALOG = ON

--   Dependency GSL_FOUND = FALSE  <============================

--   Disabling gr-wavelet support.

--   Override with -DENABLE_GR_WAVELET=ON/OFF

--

and so the packages

--   * gr-dtv

--   * gr-atsc

--   * gr-wavelet

are not being built.

BTW: I have gsl and gsl-devel installed (version 1.16-17)

Can anyone give me a hint as to what may be wrong here?

thanks
