Re: EVEmodel.c:8:26: fatal error: gsl/gsl_math.h: No such file or directory

Hello Nick,
this looks as a building set up issue not as a GSL issue. See below.

it must look at the parent folder, not at gsl folder: <PARENT 
FOLDER>/gsl/gsl_*.h

 the .c scripts

do you mean C source ?

 already contain "#include <gsl/gsl_matrix.h>". I am not sure what is causing 
this fatal error.

the C compiler cannot reach the C header.

 Any thoughts or suggestions is greatly appreciated.

Anyway, if your linux box is properly set up, it should be find.
You may try:

gcc -o myprog myprog.c  $(pkg-config gsl --cflags --libs)

Is it wild Linux server maintained randomly by a bunch of motley people
or a sane Linux box running a well-known distribution (as Ubuntu, Debian, ...) 
maintained by a guru ?
