Install[] of working WSTP executable hangs, Mathematica 10.1, linux


I am trying to use WSTP to link to the addtwo.c function example that comes with Mathematica. I have compiled addtwo successfully (took an effort) and if I run it in the command line I can connect it to Mathematica and use it. However running



Install["./addtwo"]

in Mathematica just hangs until I abort. The precompiled addtwo binary that comes with Mathematica does install fine. Is there a way to find out more about why the Install[] fails?


I compiled using the (adapted) makefile which produces:


:~$ make addtwo
/usr/local/Wolfram/Mathematica/10.1/SystemFiles/Links/WSTP/DeveloperKit/Linux-x86-64/CompilerAdditions/wsprep addtwo.tm -o addtwotm.c
gcc -c -I/usr/local/Wolfram/Mathematica/10.1/SystemFiles/Links/WSTP/DeveloperKit/Linux-x86-64/CompilerAdditions addtwotm.c
gcc -c -I/usr/local/Wolfram/Mathematica/10.1/SystemFiles/Links/WSTP/DeveloperKit/Linux-x86-64/CompilerAdditions addtwo.c
gcc -I/usr/local/Wolfram/Mathematica/10.1/SystemFiles/Links/WSTP/DeveloperKit/Linux-x86-64/CompilerAdditions addtwotm.o addtwo.o -L/usr/local/Wolfram/Mathematica/10.1/SystemFiles/Links/WSTP/DeveloperKit/Linux-x86-64/CompilerAdditions -lWSTP64i4 -lm -lpthread -lrt -lstdc++ -ldl -luuid -lWSTP64i4  -o addtwo


Note that addition of -lWSTP64i4 didn't change anything, I tried it because of this answer which was already a bit desperate.


Could it be because of my gcc version? ( 4.6.3-1ubuntu5 )



Answer



Summarizing the comments into an answer: this is really the same issue as in WSTP hangs in Mathematica 10.2.


If using dynamic linking (-lWSTP64i4 will pick up the .so library by default), then said shared library should be copied to a systemwide location or put on LD_LIBRARY_PATH.


The prebuilt examples do not exhibit this behavior because they are statically linked. The same can be accomplished by using -L${LIBDIR} libWSTP64i4.a in your link line.


If one uses the MathLink examples instead, they will work without additional requirements even if dynamically linked. The reason is that when Mathematica is started, it adds to LD_LIBRARY_PATH the $InstallationDirectory/SystemFiles/Libraries/$SystemID directory, which has a copy of the corresponding MathLink libraries, libML32i4.so and libML64i4.so.

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

equation solving - Invert and fit implicitly defined curve

I need to fit an implicitly defined curve. I thought I could get some data out of Solve , and then using FindFit . Therefore, I would like to find the relation the parametric curve defined by $F(x,y)=0$: Solve[-(1/2) + 1/2 (0.41202 BesselK[0, 0.1 Sqrt[x^2 + y^2]] + (0.101483 x BesselK[1, 0.1 Sqrt[x^2 + y^2]])/Sqrt[x^2 + y^2]) == 0, y] But I can't get an output: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help. >> Edit: In particular, I would like to fit the data coming from the curve with the expression of another curve, and not with a function $f(x)$. In particular, since this clearly looks like a cardioid , I would like it to fit to something like it. What other strategies could I try?

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...
