For my thesis I need to run a routine that measures the equivalent widths of spectral lines (robospect: https://home.ifa.hawaii.edu/users/watersc1/robospect/. I use the most recent version in combination with gsl-1-16, since robospect does not work with gsl-2 or higher. The problem is, when I run the routine i get the error in the title.

Running ldd -d -r /usr/local/lib/libgsl.so.27, I get the following

Everything seems to be installed correctly and before my recent update to Ubuntu 22.04.1 LTS it worked as intended. Is there anything I can do? I am in no way a pro when it comes to things like that. Thank you very much in advance!

Sorry for not catching this earlier but it is likely your error is to only link with -lgsl when the GSL documentation and examples make it clear you need both -lgsl -lgslcblas:

$ gcc -Wall -o gsl_spline_example gsl_spline_example.c -lgsl -lgslcblas -lm                  
$ ldd gsl_spline_example
        linux-vdso.so.1 (0x00007ffc51d16000)        
        libgsl.so.27 => /lib/x86_64-linux-gnu/libgsl.so.27 (0x00007f8e9e546000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f8e9e45f000)                                
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8e9e237000)                                
        libgslcblas.so.0 => /lib/x86_64-linux-gnu/libgslcblas.so.0 (0x00007f8e9e1f5000)                  
        /lib64/ld-linux-x86-64.so.2 (0x00007f8e9e82d000)                                                 
$ ./gsl_spline_example                  
#m=0,S=0                                           
0.000000 1.013392               
0.075377 0.980953
