4 Binary files included with this distribution
\r
5 --------------------------------------------
\r
7 The Windows version package of Maxima includes binary files
\r
8 from other Open Source projects also hosted on Sourceforge.
\r
12 gcc.exe, cc1.exe and the files in lib/gcc-lib and include/
\r
13 subdirectories are from the mingw version of gcc. This is
\r
14 available from http://prdownloads.sf.net/mingw/
\r
19 as.exe is from the mingw (http://www.mingw.org/) port of binutils
\r
20 available from http://prdownloads.sf.net/mingw/
\r
25 The files wgnuplot.exe, wgnuplot.hlp and wgnuplot.mnu are from the
\r
26 Windows distribution of gnuplot from http://gnuplot.sourceforge.net
\r
31 The files in the wxMaxima subdirectory are from the Windows distribution
\r
32 of wxMaxima available from https://wxmaxima-developers.github.io/wxmaxima/
\r
35 Maxima GUI and firewall
\r
36 -----------------------
\r
38 Sometimes Maxima GUI (xmaxima or wxMaxima) can't launch Maxima
\r
39 or issues timeout message or gets no response for Maxima commands.
\r
40 Quite probably the problem is caused by firewall and/or antivirus software.
\r
41 The Maxima GUI talks to the computational engine through a socket.
\r
42 Antivirus and/or firewall programs see that and may try to block it
\r
43 (because some malicious programs open sockets too).
\r
45 To resolve the problem:
\r
47 1. Try to find the control panel for the antivirus and/or firewall.
\r
49 2. Find the Maxima GUI on the list of blocked programs and disable
\r
50 blocking for it. The GUI program might appear as "Tcl/Tk"
\r
51 (the name of the GUI toolkit for xmaxima).
\r
54 Data Execution Prevention (DEP)
\r
55 -------------------------------
\r
56 Sometimes not only Maxima GUI but also command line Maxima
\r
57 doesn't work (maxima.bat starts and immediately quits).
\r
58 Quite probably the problem is caused by Windows DEP.
\r
59 Some Lisp implementations execute code in data areas of memory.
\r
60 Windows DEP sees that and blocks it (because some malicious programs
\r
61 execute code in data areas too).
\r
65 Include the full program path of the Maxima executable, for example:
\r
66 C:\Program Files\Maxima-5.12.0\lib\maxima\5.12.0\binary-gcl\maxima.exe
\r
67 in the list of DEP exceptions
\r
68 (Control Panel -> System -> Advanced -> Performance -> DEP)
