I can't compile it with my Texstudio compiler!

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{pst-eucl,pst-calculate,textcomp}
\begin{document}
\begin{pspicture}[showgrid](-1,-1)(8,8)
\pstTriangle[PosAngle={180,90,0}](1,2){B}(2.5,5){C}(6,2){A}
\pstInterLC[PointSymbolB=none,PointName=none]{A}{C}{C}{B}{N}{N0}\uput[0](N){N}
\psarc[origin={C}]{->}(C){0.5}{(B)}{(N)}\uput{5mm}[-10](C){75.9636\textdegree}
\end{pspicture}
\end{document}


Question 2:

When using PointNameB=none , it produces

\documentclass[12pt,pstricks,border=15pt]{standalone}
\usepackage{pst-eucl}
\begin{document}
\begin{pspicture}[showgrid](-2,-2)(3,4)
\pstTriangle[PointSymbolB=none,linecolor=blue,linewidth=1.5\pslinewidth](1.5,-1){A}(0,1){B}(-1,-.5){C}
\psset{PointNameB=none,PointSymbol=none}
\pstInterLC[PosAngle=45]{A}{B}{B}{C}{N}{N'}
\end{pspicture}
\end{document}


When using PointNameB= , it produces normally

P/s: All files are be loaded with latex->dvips->ps2pdf

1) Click on the first Log button. Then you'll get antother one right of the first one. Click on the right button and you'll get the latex original error message from the latex run. This is more helpful then the message from TeXstudio. BTW: I do not get any error message with up-to-date TeXLive

2) Use

\documentclass[12pt,pstricks,border=15pt]{standalone}
\usepackage{pst-eucl}
\begin{document}
\begin{pspicture}[showgrid](-2,-2)(3,4)
\pstTriangle[linecolor=blue,linewidth=1.5\pslinewidth](1.5,-1){A}(0,1){B}(-1,-.5){C}
\pstInterLC[PointNameB=,PointSymbolB=none]{A}{B}{B}{C}{N}{N'}
\end{pspicture}
\end{document}


• I have just edited your question with additional link. And with your code, I still get Dot style none' not defined. :-(. You can help me to see it. – Trong Vuong Dec 30 '18 at 8:45
• You should update your pst-eucl.tex`: archiv.dante.de/~herbert/TeXnik/tex/generic/pst-eucl This version is already uploaded to CTAN. – user2478 Dec 30 '18 at 8:49
• Yes, successful. Thanks. So " PointNameB= " replace " PointNameB=none " for \pstInterLC , unlike as the default, what is your idea? – Trong Vuong Dec 30 '18 at 9:21
• that is really old code and will not changed for compatibility reason ... – user2478 Dec 30 '18 at 9:23
