Programming :: MinGW - Performance Is Degarding - Version To Win32 Version
Jul 10, 2009
I've made a linux app that I'm porting to win32 winth MinGW and MSYS. It's a ticker app that reads then renders a text file to a pixmap (a tall single-line image), then it kind of scrolls the pixmap by drawing a part of it to a drawing_area, using gdk_draw_drawable() within a timeout handler set by g_timeout_add().
The problem is it works fine on linux (the scrolling is really smooth and that's the goal) but the win version is choppy and uses at least 90% of cpu resources (vs 15% with linux) like there is a big performance problem. And I'm not even sure that double buffering is set. Is it related to some mingw config or drawing_area stuff or gtk for win?
I've just upgraded from a wonderfully working v.9.10 to v.10.04 so I can install Flash and allow video to work. Apparently I can't install Flash into this older version. The performance is now unusably slow and windows move around desktop in a very limited way and cascading menus lag. I did all updates before upgrading as suggested. (The machine is a Toshiba Tecra A4)
I have several server (mailserver, webserver and lot of fileserver) all are 32 bit slackware and I am satisfied! My company plan to upgrade our server and buy a 64 bit server maybe amd x3 or opteron? Is slackware 64 bit will help boost my server performance? Or will I stick to 32 bit for now?
I have a doubt, may sound funny but wanna know whether it is possible to share DVD drive in windows [version 7] and use it in Linux system [version fedora 12]?
Which LXDE version of Linux has the newest version of Firefox and Open Office included?
I am looking for an iso file, and I am trying to run this off of a live CD for now. So I want a light version of Linux, probably LXDE, or if not, then probably XFCE. But I need a new version of Firefox and OpenOffice included.
Because, I tried burning the customizable NimbleX @ custom.nimblex.net . Pretty good, except it uses Firefox 2, and Open Office 2.3, which are outdated.
And I tried Mint XFCE, which might have been pretty good too, but it had some issue of blanking and requiring relogin after I opened hotmail frequently (user id: mint, password: blank).
The web browser and the word processing program are the most important and essential applications to me.
So are there any Linux versions in LXDE on LiveCD that include newer versions of Firefox (or at least another good browser) and Open Office (oo seems better than abi)? (Again, if no LXDE, perhaps XFCE?)
I just want to download a good version in an iso file, and burn it to a CD and get to work. Like I said the web browser and the word processing program are all important.
So really, what iso/LiveCD versions are the fastest for running on an older system, and yet have the newest browser and word processor included?
I installed debian squeeze on an old computer that I found. (Pentium 4 3.2GHz HT) I installed from the i386 version, but now the uname command shows that its an i686. I don't find many packages that I need using apt-get. Do I need to compile each package I need from source or use dpkg to install the deb of an i386 version?
Can I use the i386 version on this computer rather than the i686 version? Will it cause a signifncant performance decreaes? (I use this computer to mostly do some reading and writing and file storage, no gaming etc.) How do I force the installer to use the i386 version?
Installed Zend Server CE on 10.04 - install mostly fine. But phpmyadmin shows this error; "Your PHP MySQL library version 5.0.83 differs from your MySQL server version 5.1.41" I have followed the Zend online docs and used a DEB install. Why would these versions be different?how do I fix it so that the two are in sync?

Q1. Is there any way by which I can upgrade it to laptop version?
Sometimes a kernel image seems to have the same version as the backported kernel image, for example: linux-image-2.6.32-bpo.5-amd64 linux-image-2.6.32-5-amd64
Just got my AW M11x and I am following a thread on installation issues and work around. My question is should I install the desktop version or the Netbook version? Not sure the best location to post, if incorrect please move accordingly Wanting to run gimp, open office, wine to access MS office (use for school) and possibly install photoshop for raw work gimp cant handle.
I am using Nagios 3.2.4 monitoring tool on a Linux box with Fedora 10 installed on it and Apache version is 2.2.10. I would like to upgrade my Fedora version from 10 to latest version Fedora 13.
1. what is the difference between the repo version and the sun .rpm version? 2. will usb, printer, etc. be available to the guest os? 3. Will my computer be able to handle running 2 os? after upgrade I will have a p4, 1g ram (333 ddr), and a 250g hard drdive.
IMy goal is to install WinXP and to help test new version of openSUSE with openbox.
my laptop currently has 8GB of RAM and I wouldn't want that going to waste. I have read about the issues with flash on the 64 bit versions of buntu. Would you recommend going 64-bit or 32-bit with PAE? also, does the 10.10 kernel have PAE enabled by default?
I want to upgrade mediawiki software from version 1.6 to version 1.16 . The newer version is supposed to be installed on another server. I am trying to migrate the old mediawiki mysql database with no success.
libxml2 works fine on Linux machines. On Windows, the distribution at [URL] is built for the Microsoft C compiler/linker. The tools pexport and dlltool supplied with MinGW work fine to enable linking to these libraries EXCEPT for static data within the DLL. libxml2 is written so that calls to xmlFree, xmlMalloc and xmlRealloc dispatch through static variables in the DLL - the actual function has another name. BUT, the link library that dlltool builds has its own .globl variable that never gets initialized, and calls to xmlFree(whoever) wind up at location 0.
SOLUTION: AFTER an initial call to xmlParseFile() or some other xml function that initializes the DLL's variables, add the line:
if(!xmlFree) xmlMemGet(&xmlFree,&xmlMalloc,&xmlRealloc,NULL) This will initialize the application's static pointers to the dll's routines. (The NULL pointer would return the address of xmlStrdup, but it's a function already, not a variable <???> so it works anyway).This solution is portable - if you run on a Linux machine where the pointers are properly initialized already, it won't hurt anything.
I've been searching for an hour or so and can't seem to find a concrete answer. My endgame is having Ubuntu successfully installed (either 9.10 or 10.04) with a fully working Ati 4870x2. I desperately need some help on finding the proper configuration of OS version and driver version. I installed 10.04 with the 10.3 driver package from ATI's site and it was a no go - I had nothing but problems.
I would like to have full 3d acceleration so I can play some games through Wine. This is a powerful card - I know ATI doesn't have a great reputation in the Linux world but I really hope there is a driver version I can install to get some good results.The rest of my specs are in my signature I need to install 64 bit Ubuntu to make use all of the system and video ram.
When I compile my application, I received following error: ERROR: Source object libxml2.so has EABI version 0, but target turbine has EABI version 4. So I need a libxml2 file with ARM EABI version 4. Can I find one from the internet? or does anyone know how to create one?
