[Kst] [Bug 187752] New: build is broken when gsl header files missing

           Summary: build is broken when gsl header files missing
           Product: kst
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: dvw at ketiltrout.net


Version:           1.8.0_svn_914813 (using KDE 3.5.10)
Compiler:          gcc (GCC) 4.2.4 
OS:                Linux
Installed from:    Compiled From Sources

When ./configure is run, many gsl header files are searched for.  However, the
result of these tests appear to be discarded:

If the header files are not found, ./configure completes successfully, but
still goes on to attempt to build kst components which require these header
files.

Instead, if these gsl header files are not found, one or more of the following
should be done:

1) kst components requiring gsl should not be built

2) ./configure should complain that kst can't be built without the headers

Steps to reproduce:

1) Start with a clean copy of the kst source code.

2) remove gsl header files from the system (or, at least, from the compiler's
include search path)

3) ./configure (should complete successfully, while reporting gsl header files
missing)

4) "make"

Result:

Expected result:

The build system should not compile components requiring gsl, or else
./configure should not complete successfully, instead issuing an error message
indicating the missing header files.
