CrystalFontz CF635 : Buffer overflow after initialisation of layout

[info@…>]

Dear Sir,

I have a Suse 10.1 x86_64. I have a buffer overflow message when I do a lcd4linux -Fvvq with my CF635.

Please have a look to the dump bellow. Any idea?

Many thanks Hervé Display CF635 {

}

Log of the error

Dear Sir,

I've found this ticket, that I applyed:

Ticket #37 (closed defect: fixed) O Description unsigned char buffer[22] needs to be at least 24

Now I want to compile once again the source 0.10.0 . I downloaded it from the source link. I do

./configure

make

and I get an I2C error message after some correct lines:

gcc -DHAVE_CONFIG_H -I. -I. -I. -D_GNU_SOURCE -Wall -W -g -O2 -c

drv_generic_i2c.c

In file included from drv_generic_i2c.c:76:

lcd4linux_i2c.h:81: error: array type has incomplete element type

make: *** [drv_generic_i2c.o] Error 1

Any idea?

Thanks Hervé

Dear All,

The solution , to extend buffer size, described before is ok. SO I downloaded the latest CVS and compiled it ok. All is fine. Please CANCEL This ticket

Thanks Hervé
