Does it work better now? GML for Linux is supposed to use a library called speedy_tls. There was a bug, so the library was not actually being used. But it should be now... I downloaded this free library from the web, so I have no idea if it works or not. I have no Linux machine ATM so I cannot debug this. If someone has Linux skills, feel free to help. |

Same problem on HEAD, (i tested 6442 and 6448, the last working was 6391) But i will test it on a other ubuntu machine in the next days, if it is a problem with the lib on this system. |
|
|
According to the library docs, it must be compiled with flag -mno-tls-direct-seg-refs. http://www.kevinjhoffman.com/speedy-tls/ I have now added this flag to SCons, so you could try reconfigure+rebuild and see if it helps. |
|
|
shouldn't the flags be added only on non-windows OSes? |
|
|
And isn't it only gml which needs to be compield with this flag? |
|
|
I'm using a similar technique for windows too - fast TLS by directly accessing the FS/GS registers. So I believe it is safest to specify this flag no matter what, so that GCC does not use these registers for some internal TLS stuff. The flag is only set when compiling with gml=yes. All files being compiled will need the flag though, to make sure that nothing else interferes. |
