   Before searching for some Raspberry PI 5 group, I'll post   
   my problem here, some smart person here might also   
   work with the PI.   
      
   I am trying to build a package of C routines that I   
   have built and maintained for many years. The problem   
   is that the libs required by the programs have, apparently,   
   been re-written for the Debian version that runs on the   
   PI 5. The compile/link command that has worked for   
   gcc and libs up to Slack 15 is:   
      
   magic:magic.o eigen.o fft.o order.o xplot.o best.o minv.o utils.o xtfuncs.o   
   mygetline.o mymouse.o   
       gcc -o/root/bin/magic -Xlinker -Map=/ram/MAP.map   -lm -L/usr/lib64/gsl   
   -lgsl -lgslcblas -rdynamic -ldl -lgpm \   
       magic.o eigen.o fft.o order.o xplot.o minv.o  best.o utils.o xtfuncs.o   
   mygetline.o mymouse.o   
      
   And similar lines for the rest of the Makefile.   
      
   As you can see, the package is a lot of mathematical routines. The   
   problem is that the math libraries have all be renamed, or something   
   else and none of the math functions compile. I get unresolved   
   errors for all the math functions log,exp,sin,cos..... as well   
   as anything using the Gnu math libraries.   
      
   I have used "dpkg -l" on the PI and I see that the libraries are   
   there, but the names are different and from the dpkg output   
   I can't find a makefile command that works.   
      
   The really surprising thing is that I got the PI5 about a month   
   ago, and I built the system from an image of March 15 2024.   
   I got everything in that system to work, including the math   
   package of interest.  Then something choked and the system   
   would no longer boot. I tracked down the problem to something   
   that clobbered bash. Honestly it wasn't anything I did because   
   I left the system running for a couple of weeks, and when   
   I came back to it it was trashed. My guess is that some   
   "update" was the problem.   
      
   Starting with the same image, I rebuilt the system.   
   After starting, it does some updates and everything   
   but the math package works.   
      
   Perhaps someone in the Slack group also plays with the   
   PI and can give me some help.  BTW, the main reason   
   for using the PI is that you get a free version of   
   Mathematica running on the PI.   
      
   Thanks for any help.
