Re: [Gnuplot-info] How to ignore "popen failed"?

[ivana r. <iva...@mf...>]

Hi all,

I'd like to declare I don't understand windows. So just small observation.

If I unzip current non-installing version (gp52rc2-win64-mingw.zip), I
get few exe-files in bin-directory.

If I run gnuplot.exe under Win7Pro, it launches in terminal mode. If
dir failes, error message is printed, syscall returns en empty string,
and GPVAL_ERRNO is set correctly. Almost as on linux.

Contrary, if I run wgnuplot.exe, a new window is created. Another
window is created as well for each dir call (and !dir just blink its
window, no data remains). The popen_failed is returned if dir running
in the new window fails.

So I guess, the problem consist in OS libraries: It would be
acceptable solution to run gnuplot scripts with potentially crashing
syscalls by gnuplot clones that are compiled via libraries that don't
produce new windows for syscall.

Sincerely

Iva
