Hi, I can reproduce this error on Fedora 36 desktop.
Just to make sure, did you build fricas in desktop or in (remote) console? I assume you are building under desktop and you can see the drawings popup. But that is not expected. As you can see in the log, there's possible memory fault (double free or corruption (!prev)) and if you check dmesg, there might be seg faults. But seems that's not directly linked with this error. I think this is somewhat related with https://github.com/fricas/fricas/issues/57 The solution is same: remove "-n 0" from XVFB=... in configure and configure.ac It is strange that we are still using "-n 0": first the help shows that it is deprecated to use "-a" together with "-n"; second, it's easy to conflict with current DISPLAY to use "0". - Qian On Thursday, October 27, 2022 at 7:42:07 AM UTC+8 wrote: > Hi all, > When trying to build Fricas, I get the following error when trying to make. > My system is: > Fedora 36 > > Error: > making explot2d.input > parsing: ExPlot2DPolar > writing: draw(sin(4*t/7),t = 0..14*%pi,coordinates == polar) > Warning: could not get the 9x15 font for messageFont > Warning: could not get the 8x13 font for buttonFont > Warning: could not get the 9x15 font for headerFont > Warning: could not get the 9x15 font for titleFont > Warning: could not get the 9x15 font for graphFont > Warning: could not get the 6x10 font for unitFont > double free or corruption (!prev) > parsing: ExPlot2DAlgebraic > writing: draw(y^2 + y - (x^3 - x) = 0, x, y, range == [-2..2,-2..1]) > Warning: could not get the 9x15 font for messageFont > Warning: could not get the 8x13 font for buttonFont > Warning: could not get the 9x15 font for headerFont > Warning: could not get the 9x15 font for titleFont > Warning: could not get the 9x15 font for graphFont > Warning: could not get the 6x10 font for unitFont > parsing: ExPlot2DFunctions > writing: draw(sin(tan(x)) - tan(sin(x)),x = 0..6) > Warning: could not get the 9x15 font for messageFont > Warning: could not get the 8x13 font for buttonFont > Warning: could not get the 9x15 font for headerFont > Warning: could not get the 9x15 font for titleFont > Warning: could not get the 9x15 font for graphFont > Warning: could not get the 6x10 font for unitFont > parsing: ExPlot2DParametric > writing: draw(curve(9 * sin(3*t/4),8 * sin(t)),t = -4*%pi..4*%pi) > Warning: could not get the 9x15 font for messageFont > Warning: could not get the 8x13 font for buttonFont > Warning: could not get the 9x15 font for headerFont > Warning: could not get the 9x15 font for titleFont > Warning: could not get the 9x15 font for graphFont > Warning: could not get the 6x10 font for unitFont > /usr/bin/xvfb-run: line 186: kill: (375936) - No such process > make[3]: *** [Makefile:689: explot2d.pht] Error 1 > make[3]: Leaving directory '/home/agnelo/Documents/Fricas/fr-build/src/doc' > make[2]: *** [Makefile:772: copy-to-target] Error 2 > make[2]: Leaving directory '/home/agnelo/Documents/Fricas/fr-build/src/doc' > make[1]: *** [Makefile:224: all-doc] Error 2 > make[1]: Leaving directory '/home/agnelo/Documents/Fricas/fr-build/src' > make: *** [Makefile:250: all-src] Error 2 > -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
