#15 megaglest 3.6.0.2 crashes before the menu screen appears
I've build glest for openSUSE 12.1. When I run it i get an segfault.
It looks like it's caused by ftgl (2.1.3~rc5 ) I've also tried your precompiled version, that one showed the same result.
The rpm's can be found in http://download.opensuse.org/repositories/home:/worldcitizen:/test/openSUSE_12.1/ as for games glew is broken I've build against version 1.6.0 as this one is not broken.

I've attached a gdb file. I hope it's helpful.
If I need to test or try something please let me know.
gdb file
Please run in verbose mode and pipe console output to a log file and attach its contents:
./megaglest --verbose >info.log
Thanks
output of /usr/bin/megaglest --verbose >info.log
The error.log file assosiated with /usr/bin/megaglest --verbose >info.log
I've attached the info.log and the .megaglest/error.log file
Try editing english.lng and add the line:
MEGAGLEST_FONT=$APPLICATIONDATAPATH/data/core/fonts/LinBiolinum_RB.ttf
(or edit it to point to a path with the font file mentioned). There are numerous ways to handle this situation but I first want to confirm that the problem is that its not finding the proper font. Thanks. Also where does that font normally live. The game looks for this font be default then falls back to:
tryFont = getenv("MEGAGLEST_FONT");
CHECK_FONT_PATH("/usr/share/fonts/truetype/linux-libertine/LinLibertine_Re.ttf")
CHECK_FONT_PATH("/usr/share/fonts/truetype/freefont/FreeSerif.ttf")
CHECK_FONT_PATH("/usr/share/fonts/truetype/freefont/FreeSans.ttf")
CHECK_FONT_PATH("/usr/share/fonts/truetype/freefont/FreeMono.ttf")
The problem is solved. I hadn't installed data/core/fonts of megaglest-source-embedded-3.6.0.2.tar.xz .
I like the idea that removed packages like libircclient and libminiupnpc, the standard libs need to be used.
I need to find out how to handle the fonts without usage of the megaglest-source-embedded tarball.
openSUSE has for example font /usr/share/fonts/truetype/LinBiolinum_RB.otf (not ttf) in LinuxLibertine-5.1.3-2.1.1.noarch .
Thank you very much for your help. It's great megaglest is now fixed for openSUSE.
Extra information the freefonts are found in freefont-0.20110523-4.1.3.noarch
/usr/share/fonts/truetype/FreeMono.ttf
/usr/share/fonts/truetype/FreeSans.ttf
/usr/share/fonts/truetype/FreeSerif.ttf
Might there way that megaglest can use the standard "Xorg" truetype fonts?
Patch I used so megaglest-source-embedded-3.6.0.2.tar.xz . doesn't need to be used
I've used a patch to solve the issue. I've attached the patch.
I don't know if this is the best way.
Ok now that we know what is going on (its wasn't finding the fonts) we can try to address this properly. First of all I had code that was supposed to try using fontconfig (to find fonts) but i did not test it and it wasn't compiling right. Currently thats fixed in svn and fontconfig should find the fonts on any distro as long as they are installed and regitered with fontconfig.
For now (using the current release code) you have multiple options. You could edit 3 languages files and place the correct path to the font on opensuse in them. Edit english.lng, chinese.lng and japanese.lng and set the proper path for the entry:
MEGAGLEST_FONT=$APPLICATIONDATAPATH/data/core/fonts/<some font name here>
Set the proper path and fontname for opensuse (chinese and japaense use a font for their language which is quite standard for most Linux distros)
Thanks
Similar problem on Arch linux .....

Can you try to install FreeMono (ttf-freefont) - Unicode and see what happens i.e. if it solves the issue?
https://wiki.archlinux.org/index.php/Fonts
ttf-frefont was already installed
Can you find out where the fonts have been installed and what the exact names are?
FreeMono.ttf
FreeSans.ttf
FreeSerif.ttf
Just check they are:
/usr/share/fonts/TTF/FreeMono.ttf
/usr/share/fonts/TTF/FreeMonoBold.ttf
/usr/share/fonts/TTF/FreeMonoBoldOblique.ttf
/usr/share/fonts/TTF/FreeMonoOblique.ttf
/usr/share/fonts/TTF/FreeSans.ttf
/usr/share/fonts/TTF/FreeSansBold.ttf
/usr/share/fonts/TTF/FreeSansBoldOblique.ttf
/usr/share/fonts/TTF/FreeSansOblique.ttf
/usr/share/fonts/TTF/FreeSerif.ttf
/usr/share/fonts/TTF/FreeSerifBold.ttf
/usr/share/fonts/TTF/FreeSerifBoldItalic.ttf
/usr/share/fonts/TTF/FreeSerifItalic.ttf
You can try:
mkdir -p /usr/share/fonts/truetype/freefont
ln -s /usr/share/fonts/TTF/FreeSerif.ttf /usr/share/fonts/truetype/freefont/FreeSerif.ttf
ln -s /usr/share/fonts/TTF/FreeSans.ttf /usr/share/fonts/truetype/freefont/FreeSans.ttf
ln -s /usr/share/fonts/TTF/FreeMono.ttf /usr/share/fonts/truetype/freefont/FreeMono.ttf
Can you check if this solves the issue?
Check that the size of the Skull Model and the Texture Map 10 are 70 Kbytes. I had a corrupted download (Matched MD5 anyway) that exhibited a Segment fault/Crashed before Menu appears" and the size of those two files was 66 Kbytes. After I replaced those two files with 70 Kb sized copies I got from the data sources it went to the Menu OK.
Please ignore the comment by carlmccall, it is irrelevant to this issue.
Narendiran: Please start a new bug report for every new issue, even if it may seem releated to an existing one.
I'm marking this bug as fixed since the original bug report is, according to Softcoders' latest comment, fixed in subversion. The original bug reporter (only), Worldcitizen, is welcome to comment on and reopen this bug should this turn out to be incorrect.
Thanks to all of you.
We are preparing a 3.6.0.3 patch release which should fix this issue since fontconfig works properly and should find fonts on any fontconfig implementation distro. This release will be fully backwards compatible with the current 3.6.0.2 release (which is what is likely to be released on Debian and Ubuntu upcoming releases)
