Hello Plplot
I am at present migrating some PlPlot programs from Windows 10 to linux
(mint 64 bit),
To facilitate this I have downloaded cmake and Plplot-5.15.0.tar.gz from
your website.
Following the instructions from your wiki I built an installation
consisting of static
libraries. In order to test the installation I wrote a very simple program
PlPlotTest.c:
#include <stdio.h>
#include "plplot.h"
int main()
{
printf("Plotting example\n");
plsdev("ps"); plsfnam("TestPlplot.ps");plinit();
plenv(-1.0 , 1.0 ,-1.0,1.0,1,2);
pljoin(-0.5,-0.5,0.5,0.5);
plend();
printf("Plot finished\n");
return 1;
}
and attempted to compile it with
gcc -c -I /home/peter/plplot/install_directory/include/plplot PlPlotTest.c
gcc -o PlPlotTest.exe PlPlotTest.o -L
/home/peter/plplot/install_directory/lib -lplplot -lcsirocsa -lqsastime
-lm -lX11
An object file PlPlotTest.o was generated with no errors, but the linking
failed with the messages:
/usr/bin/ld:
/home/peter/plplot/install_directory/lib/libplplot.a(xwin.c.o): in function

/usr/bin/ld: xwin.c:(.text+0xcec): undefined reference to `pthread_join'
collect2: error: ld returned 1 exit status
I am very new to linux. Can you tell me what the linking should be?
Best Wishes, Peter
