[Help-gsl] 32 bit and 64 bit GSL co-existing

[Vihan Pandey]

Hello,

Is it at all possible to install with binaries or compile GSL such
that I have both 32 bit as well as 64 bit support? I am on a 64 bit
system.

I have tried package wise installation on Ubuntu 14.04 but I can
either have 32 bit GSL or 64 bit GSL bit not both e.g :

# sudo apt-get install libgsl0ldbl:i386 gsl-bin:i386 libgsl0-dev:i386

Will give me support for 32 bit packages. But I cannot compile and run
code for 64 bit.

# sudo apt-get install libgsl0ldbl gsl-bin libgsl0-dev

Will give me support for 64 bit packages. But I cannot compile and run
code for 32 bit.

Ideally I would like scenario wherein both the 32 bit and 64 bit GSL
can co-exist on the same 64 bit machine and I can compile with
-I/path/to/32/bit/includes -L/path/to/32/bit/includes for building 32
bit binaries, -I/path/to/64/bit/includes -L/path/to/64/bit/includes
for building 64 bit binaries for each respected 32 bit or 64 bit
target.

Any ideas?

If any additional info is required from my side, please let me know.

Best,

- vihan
