[Altera_Forum]

Hi everyone 

When I used the on-chip memory,I meet the error as following:  D:/QuartusII_project/nios_turorial_2/lights_syslib/Debug/liblights_syslib.a(alt_dev_llist_insert.o)(.text+0xdc): In function `alt_get_errno': /cygdrive/d/altera/kits/nios2_51/components/altera_hal/HAL/inc/sys/alt_errno.h:81: Unable to reach errno (at 0x00000024) from the global pointer (at 0x00009a0c) because the offset (-39400) is out of the allowed range, -32678 to 32767.   I want to konw how to deal with the errors.Waiting for help!

You should try using the search feature of the forum. Search for "global pointer". There is a lot of information on this topic. 

 In any case, the -G0 (that's zero) compiler flag should prevent data from being linked into .sdata and/or .sbss.  Cheers,  - slacker
