How to link gsl to another tool?

ixcrpts · 09-21-2014, 05:45 AM

Hello,

I am trying to install one software which requires gsl and giving me this error.
fatal error: gsl/gsl_vector.h: No such file or directory

So, I installed gsl-1.16.
./configure --prefix=/path_to_dir/
make
make install

I am working on a server, so I could not install it as root via sudo.
So, now the required files are not in /use/local/... dir and I do not know how to link these gsl files, So that I can install my tool.

Any idea regarding gsl using locally would be appreciated.

Thanks

The syntax is,
ln -s <what> <where>

Installing gsl to /home/name/ :

$ tar xvf gsl-1.16.tar.gz
$ cd gsl-1.16/ && ./configure --prefix=/home/<name>/
$ make && make install
... then you will get /home/<name>/include/gsl/gsl_headers.h

For other applications to compile with the gsl headers,
please use e.g. CFLAGS=-I/home/<name>/include
.. or ./configure --with-gsl-headers=/home/<name>/include

Thanks for your help fatmac.
The error of include files are solved. But now I am getting this error.

/usr/bin/ld: cannot find -lgsl
/usr/bin/ld: cannot find -lgslcblas
collect2: error: ld returned 1 exit status

Any help regarding this?

← Ref. post #4.

CFLAGS=-L/<location-of-the_gsl-libraries>
.. or ./configure --with-gsl-libs=<location-of-the_gsl-libraries>

Thanks knudfl.
I use this command and I am getting the same error.
/usr/bin/ld: cannot find -lgsl
/usr/bin/ld: cannot find -lgslcblas

So..
CFLAGS=-L/<location-of-the_gsl-libraries>
means:
CFLAGS=-L/</../gsl-1.16/lib>

I used this with make and also tried directly.

I found in the make file the lgsl and lgslcblas is defined like this..
LIBS += -lgsl -lgslcblas

If the gsl file is installed in the tool directory, would that be a problem?

OK, you can try ...

$ export CFLAGS=-L../gsl-1.16/lib
