CERNLIB, Dis45, and TDR on MacOS X

Preparation: lapack

Notice that as of CERNLIB v.2001, lapack routines have been removed from mathlib. You thus need to install the lapack and blas libraries. In addition if you want to use paw++, you need OpenMotif libraries:

$ su
# apt-get update
# apt-get install lapack blas openMotif-devel Libcompat
# apt-get clean

If you just want to use precompiled binary packages, go directly to Installation subsection.

CERNLIB-2006 Building Procedure

 MacOS X Release 10.4
 gcc-4.2.0-svn20061005b
 Libcompat-14.1-2f
 lapack-3.0-26d
 blas-3.0-26d
 openMotif-2.3.0-10.4osx2

[0] Preparation

In the following, <somewhere> stands for a directory into which you downloaded necessary tarballs or patches, while <user name> means your login name. Replace them as needed according to your environment.

# cd /
# rm cern
# mkdir /Users/cernlib
# ln -s /Users/cernlib cern
# cd /cern
# for i in `ls <somewhere>/src_*.tar.gz`; do tar -zxvf $i; done
# ln -s 2006 new
# ln -s 2006 pro
# mkdir -p 2006/work
# chown <user name> 2006/work
# chown <user name> 2006
# cd 2006/src
# patch -p1 -s < <somewhere>/cernlib-2006-macosx10.4.patch
# exit

where the patch is to work around some minor remaining problems.

          ALL TESTS PASSED

1. Mathlib problem with C208 (quartic equation solver) is new and is due to csqrt in libm: csqrt selects the solution for the return value by looking at the sign of the imaginary part of the argument, which causes some unexpected behavior like:

$ cat test.cxx
#include <cmath>
#include <complex>
#include <iostream>
int main()
{
   using namespace std;
   complex<double> z1 = -1.;
   complex<double> z2 =  1.;
                   z2 = -z2;
   cerr << "z1 = " << z1 << " sqrt(z1) = " << sqrt(z1) << endl;
   cerr << "z2 = " << z2 << " sqrt(z2) = " << sqrt(z2) << endl;
   return 0;
}
$ g++ test.cxx
$ ./a.out
z1 = (-1,0) sqrt(z1) = (0,1)
z2 = (-1,-0) sqrt(z2) = (0,-1)

where I expect naively that both of z1 and z2 to be (0, 1). The quartic equation solver (drteq4) returns correct solutions but in different order because of this behavior.

2. Mathlib problem with C327 has been there since 10.3, a precision problem for modified Bessel functions (tsbvsl).

3. Mclibs problem with isajet has been there since 10.3 but overseen, since the nonzero exit code from g77's stop statement has not been treated as an error unlike gfortran.
 

Installation of Binary Packages

# apt-get update
# apt-get install cernlib
# apt-get clean
# ln -s 2006 /cern/pro

By default cernlib will be installed under /cern. Add /cern/pro/bin to your PATH in order to use PAW, PAW++, etc.
