Re: [Help-gsl] Linking GSL [noob]

[Fg Nu]

Rhys,

That is precisely what was happening. I was wondering why the nesting structure 
of the header directives was not reflected in the directory structure "on the 
ground", till I figured that GSL would need to be compiled. 

Now I am in the predicament since compiling GSL is not as straightforward as 

./configure
make install
make 

I will use this email to document my efforts for posterity. :)

1) I first installed msys (http://www.mingw.org/wiki/MSYS), entered bash, and 
tried ./configure, but I think that the shell finds a different version of sed 
somewhere in my search folders, and the ./configure exits with many errors. So, 
I removed that directory from my path temporarily. The ./configure now 
completes smoothly.

2) The make install still exits with error code 1, since it can't find a 
particular header file ("gsl_maxfit.h"), and this is a fatal error (code=2).

3) make trundles along for a while before it stops with error codes 1 and 2. 

4) I try make install  and make again (for the heck of it).

4)  I am still a little confused about the version of make being used since if 
you follow the linked stackoverflow question, you will note that I have 
answered my own question -- the problem was that the wrong version of make was 
being called when I was calling make from the command line, and I had to 
explicitly call mingw32-make instead.
Also, when I was installing the msys toolset, it asked me to rename the make in 
the MinGW installation to mingw32-make instead, which I did not do before 
trying to compile GSL.

This is where I decided to call it a day. Tomorrow I will try again to compile 
GSL and run a small example with it to see if the errors as superfluous and I 
can actually work with GSL anyway.

Any suggestions or tips for installing GSL on a Windows machine?

Thanks

S.O. is amazing but not magic.  Patience. :P

This sounds like you are not running 'make install' before trying to
compile and link against GSL.  Instead, the sounds like you are simply
running 'make' and then trying to compile and link against the built
sources.  Is that the case?  I ask because I expect installed headers
to be in locations like <gsl/gsl_multifit.h>.
