I had just installed the latest ATI video drivers for Linux onto my Slackware 11 (with kernel 2.4.33.3); I have Radeon Mobility X600 with 64MiB of non-shared memory.

Running glxgears, I got ~2050 FPS (glxgears window focused) and ~4900 FPS (console window focused, glxgears window out of focus).

But running fgl_glxgears yielded values as low as 1 FPS! As fgl_glxgears is much more similar to the real-world game visuals, it’s apparent that no game will be playable at e.g. 0.2 FPS.

Also, there were numerous repetitions of a single error in the console window:

FGLTexMgr: open of shared memory object failed (Function not implemented) __FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed! fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!

I found the solution which worked perfectly for me:

Today, after starting ./configure to make one of the programs, I noticed this in the logs:

I don’t know what is that intended to mean, but this is definitely funny: configure script, able to detect if the Force is with Skywalker…

I’ve been away from Internet for quite a long while… but now I’m back, and writing again!

As I’m moving to Linux as my primary OS, my readers should expect more Linux-related posts in the nearest future. However, this does not mean any changes in the overall blog ideology and priorities – they will be kept as they are now.

I’m currently completing a DNA sequence-analysis server, which will be announced later; I might post additional details on making an automated pipeline-like analysis web-servers for bioinformatics and/or data analysis; but the decision “to post or not to post” will be made based on “popular demand” (if any…).

When ‘make’ing krename (after ./configure, of course), it failed with an error message like:

libtool: link: `/usr/libGL.la’ is not a valid libtool archive

After reading this topic (in Russian), I found that libGL.la is a configuration file for libGL.so.
This configuration file is created when installing ATI or nVidia video drivers – they replace the bundled libGL.so and create libGL.la.

The solution to the “absent libGL.la” file is, thus, either to install ATI/nVidia drivers (if you have ATI/nVidia video card), or to manually create “fake” libGL.la.
Here is the sample of “fake” libGL.la (to copy-paste, click the “Plain text” header) :

Today I was looking for some simple but convenient source-code editor. I came across this post, and decided to try Geany. I’m using Slackware 11 at the moment, and as there were no packages available, I downloaded Geany source to compile and install.

However, the ‘configure’ script failed. When trying to compile ‘conftest.c’ with gcc, the following error was produced:

libc.so: file format not recognized; treating as linker script

(Note 1: in the error above, I removed all the paths which were prepended to the actual error message.)
(Note 2: I suspect that this error is the result of incomplete/failed/erroneous update of glibc slackware package I attempted a while ago. Will have to fix that more properly than described below.)

Here’s the solution which helped me to install Geany successfully:
