MaxIDE segmentation fault
Archives Forums/Linux Discussion/MaxIDE segmentation fault
| ||
| Okay, after downloading all dependencies on another post here and running a script, I still am unable to get the MaxIDE to run. I am running Ubuntu 10.04 32 bit. Any ideas? |
| ||
| I'm running Ubuntu 10.04 64-bit with no problems at all. I do recall seeing mention that the new version 1.40 eliminates some crashing bug on Linux - I'd make sure you have the latest update to start with. |
| ||
| What version of BlitzMax are you using? Try a clean install of another version such as v1.39. |
| ||
| MaxIDE 1.39 does have known SegFault'ing issues with 10.04. MaxIDE 1.40 is definitely a better shot on Linux. |
| ||
| Tried MaxIDE 1.40 and its the same thing. Would it have anything to do with FLTK in Gnome? |
| ||
| Try launching maxide from the console: cd ~/blitzmax ./maxide which may tell you more about what is failing. do you have multiple monitors or compiz enabled? Also you can test the BlitzMax compiler is functional from console (with correct permissions) by changing dir to the blitzmax/bin folder and typing ./bcc |
| ||
| I tried from the command line and it literally gives me "segmentation error". Thats literally it. BCC works fine. I am currently using the Gedit plugin and hate it with a passion. By the way, I appreciate all the help. -SEO |

| I tried from the command line and it literally gives me "segmentation error". Thats literally it. BCC works fine. I am currently using the Gedit plugin and hate it with a passion. In more detail, I did try the community version and it is giving me the following error when attempting to launch the IDE: -laptop:~/Programs/BlitzMax$ ./MaxIDE ./MaxIDE: error while loading shared libraries: libgtkembedmoz.so.0d: cannot open shared object file: No such file or directory When I try the standard 1.40, this is the output: -laptop:~/Downloads/BlitzMax$ ./MaxIDE Segmentation fault By the way, I appreciate all the help. -SEO |
| ||
| How's your GDB knowledge? If you own MaxGUI, you could try compiling a debug build of MaxID (would require a tweak to BMK first though to stop C debugging symbols from being stripped) and then running with GDB to trap the segfault? Unfortunately I don't have access to a Linux computer for over a month, so I can't send you one myself. |
| ||
| -laptop:~/Programs/BlitzMax$ ./MaxIDE ./MaxIDE: error while loading shared libraries: libgtkembedmoz.so.0d: cannot open shared object file: No such file or directory Try installing the package "libxul0d". Use this to check you have all Bmx dependencies installed. sudo apt-get install gcc g++ libxxf86vm-dev libglu1-mesa-dev x11proto-core-dev x11proto-gl-dev x11proto-kb-dev libasound2-dev build-essential libidn11-dev libxft-dev x11proto-xext-dev libxpm-dev Also check MaxIDE and the files in "BlitzMax/bin" to see if they have execute permissions (right-click > properties > permissions tab > execute checkbox). |
| ||
| Unfortunately, that lib isn't available for install in 10.04 so that's not an option. All other Linz are installed. |
| ||
| I have uploaded a debug version of MaxIDE built with latest sources here that may help us work out what is going on: http://max-gui.googlecode.com/files/maxide.debug.tar.gz |
| ||
| allen@allen-laptop:~$ cd Programs/BlitzMax allen@allen-laptop:~/Programs/BlitzMax$ ./maxide.debug Segmentation fault allen@allen-laptop:~/Programs/BlitzMax$ Thats all it gives me. I've debugged errors before but when this is literally the only output I get, tis rather frustrating. Lol. I did try the getlibs program and I get this: allen@allen-laptop:~/Programs/BlitzMax$ getlibs maxide.debug This application isn't missing any dependencies Again, I greatly appreciate the help. |
| ||
| Maybe try running the dependency script again from the console and watch for any errors. Also if you can try "gdb maxide.debug" and then "r" to run, I'm curious if that gives any more info. |

| Hi Sonari, Anything reading the length of a string with null pointer will I assume cause this crash. Can you also include output of gdb backtrace command "bt" once it has crashed, thanks. Also, you could try removing /renaming the ini file located in $BlitzMax/cfg folder. |

| ||
| There is no /cfg folder in my BMX folder Well there should be. Try creating a cfg folder and see if that fixes it. If that doesn't work then try creating this file manually in cfg folder: ide.ini Also, try putting your BlitzMax folder in your home/username folder instead of in Programs. |

| Its odd that all the ones I've downloaded never came with a /cfg folder. The IDE is supposed to create it. Maybe it is conflicting dependencies. Try running this to check you don't have the 64bit libs installed: sudo apt-get install gcc-multilib g++-multilib Edit: re libxul0d: Unfortunately, that lib isn't available for install in 10.04 so that's not an option. All other Linz are installed. You could try installing it yourself with: sudo apt-get install libxul0d Also make sure you have the universe repository enabled ie. check 'Software Sources'. If that doesn't work try xulrunner instead. |
| ||
| All those except libxul0d are installed and I have xulrunner installed by default. I'm running 32 bit Ubuntu, btw. I don't know why the IDE won't even start Lol. |
| ||
| Well you shouldn't have the 64bit libs installed if you're in 32bit so try removing them with: sudo apt-get remove gcc-multilib g++-multilib |
| ||
| Tried removing the 64 bit libs and no luck. |
| ||
| If you are really out of luck and can't get the IDE to start up give gedit a try (http://www.blitzbasic.com/Community/posts.php?topic=91279) You said compiling is functioning properly, so it should work. Have you tried to rerun the dependency installer from skidracer? |
| ||
| Tried that. The reason I hate the gedit plugin is because I cannot get it to save then compile unless I save it as a certain name pre-specified. Thanks all the same. |
| ||
| I have uploaded a new maxide.debug.noxft.tar.gz file for you to test here: https://sourceforge.net/project/admin/explorer.php?group_id=338391 It has disabled new xft font system which is possible cause of your problems and also will log more messages to console if it runs at all. If it fails to produce anything but segment faults you may want to try installing the MaxGUI module from same location and after building modules and docs try say the CreateWindow example in the docs from your current BlitzMax setup. |
| ||
| Problem being is that I don't have permission to get the new file. |
| ||
| http://sourceforge.net/projects/maxgui/files/ |
| ||
| BEAUTIFUL!!!! WORKS LIKE A CHARM!!! So in detail, what is the xft and why would a typical 32bit Ubuntu system not be able to handle it? |
