[Plplot-devel] Build result for Plplotter5.2.0 on Solaris

[Pankaj L. <pa...@da...>]

Hi All,

I found following while building and testing the Plplotter 5.2.0 with tcl/tk
driver. Its bit long, sorry for that. I hope it would be useful to other
Plplotter user.

0. I am using Solaris 8, ActiveTcl8.4 versions of tools. I have downloaded the
plplot-5.2.0.tar.gz from the Plplotter site on 12 Feb 2003.

1. A bug which causes value of var variable as 5.1.0 in pkgindex.tcl file. I
believe this is fixed.

2. If I define TCLLIBDIR and TKLIBDIR environment variables, configure script
does not look for the correct version of tcl/tk library for linker. It just
generates -ltcl, -ltk flags for linker. I used to work around to solve this. I
created a softlink to appropriate libraries. eg. for -ltcl I created a softlink
libtcl.so to libtcl8.4.so and so on or I have removed the above environment
variable to force configure script to go through appropriate folders.

3. When I define USE_TCL_STUBS, USE_TK_STUBS compiler switches for tcl/tk
related files, I am getting compilation error in "tclMain.c" for following lines

EXTERN int Tcl_LinkVar();
int (*tclDummyLinkVarPtr)() = Tcl_LinkVar;

I have commented these lines and build was successful.

4. After building the libraries, I have used Plplplotter package for my testing.
When I try following on wish prompt
% package require Plplotter
5.2.0
% Plplotwin .p1
% pack .p1
% Plplotwin .p2

After the second call, My wish prompt used crash throwing some Xwindows error in
"XCreatePixmap()" function in "tkwin.c" file when Xsync() is called in the same
function. I found the problem was with following line.

dev->pixmap = Tk_GetPixmap(tkwd->display, Tk_WindowId(tkwin),
     Tk_Width(tkwin), Tk_Height(tkwin),
     DefaultDepthOfScreen(Tk_Screen(tkwin)));

When I comment these and use following  lines

dev->pixmap = Tk_GetPixmap(Tk_Display(tkwin), Tk_WindowId(tkwin),
     Tk_Width(tkwin), Tk_Height(tkwin),
     DefaultDepthOfScreen(Tk_Screen(tkwin)));

Plplotter works fine. Incidentally, the above lines are commented in the source
code with some explanation.

5. When I try to link standard tcl/tk static libraries like libtcl8.4.a etc, I
am getting redefinition linking error for following function in tclMain.c.
void TclSetStartupScriptFileName(char *fileName);
char *TclGetStartupScriptFileName(void);.
Again I am successful in building the package once, I comment the above
functions.

Currently I am able to use Plplotter package on Solaris 8 with ActiveTcl 8.4.

Please let me know if anyone has better solution for these problems.

Thanks
Pankaj.
