nios2_51 : Driver compilation problem

[Altera_Forum]

Hi  

 We have migrated from nios2 => nios2_51 and I am trying to compile with nios2_51 an old driver which has already been compiled under nios2.  I have warnings when I compile it and the insmod is refused on the target.    On the board I have the following message :  GXEOE: Unknown symbol memcpy JGXEOE: Unknown symbol memset JGXEOE: Unknown symbol __up JGXEOE: Unknown symbol __down_interruptible insmod: cannot insert `/home/JGXEOE.o&#39;: Unknown symbol in module (-1): No such file or directory  When compiling with a makefile as recommended on the mail (Post# 20 May 2 2005 by Jwistead) i have the following warnings in verbose mode V=1   Building modules, stage 2. make -rR -f /cygdrive/c/altera/kits/nios2_51/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x/scr ipts/Makefile.modpost  scripts/mod/modpost -i /cygdrive/c/altera/kits/nios2_51/bin/eclipse/workspace/kernel_stm1_ed3/build/Module.symvers v mlinux /cygdrive/m/huon3_hds_esoe_dev_7570r1_01_ln/hds_esoe/Stm1oE/Test/jgxeoe_driver/JGXEOE.o *** Warning: "__up" [/cygdrive/m/huon3_hds_esoe_dev_7570r1_01_ln/hds_esoe/Stm1oE/Test/jgxeoe_driver/JGXEOE.ko] undefined ! *** Warning: "__down_interruptible" [/cygdrive/m/huon3_hds_esoe_dev_7570r1_01_ln/hds_esoe/Stm1oE/Test/jgxeoe_driver/JGXE OE.ko] undefined! *** Warning: "memset" [/cygdrive/m/huon3_hds_esoe_dev_7570r1_01_ln/hds_esoe/Stm1oE/Test/jgxeoe_driver/JGXEOE.ko] undefined! *** Warning: "memcpy" [/cygdrive/m/huon3_hds_esoe_dev_7570r1_01_ln/hds_esoe/Stm1oE/Test/jgxeoe_driver/JGXEOE.ko] undefined!  In the vmlinux.map of my kernel memcpy and memset are present !  I don&#39;t understand why the symbols are no more found.  I seems that the folders are not exactly the same between nios2 and nios2_51   Has somebody the same trouble ?  Thank you  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif rv
