Re: [Help-gsl] undefined reference to `gsl_filter_gaussian_alloc'

[Sergey Shcherbina]

Hi all,

I am trying to compile an example from the 
https://www.gnu.org/software/gsl/doc/html/filter.html and 

gcc is producing the following errors :

/GaussianSmoothedSignalx002c.o: In function `main':
GaussianSmoothedSignalx002c.c:(.text+0xa6): undefined reference to 
`gsl_filter_gaussian_alloc'

GaussianSmoothedSignalx002c.c:(.text+0x43e): undefined reference to 
`gsl_filter_gaussian_free'
collect2: error: ld returned 1 exit status

I downloaded gsl-2.5.tar.gz and made next steps:

./configure

make

make install

but it didn't update old version where no gsl_filter. 

I appreciate any help.

Thank you!

Serge.
