Linux Kernel Compile Problem

[Altera_Forum]

Not sure if this is the correct location for this post but here goes anyway 

 I am building uClinux-dist from nios2-linux06212010 and using nios2-linux-gcc ver. 3.4.6  I am building the kernel up to the following point and then...  LD init/built-in.o  LD .tmp_vmlinux1 kernel/built-in.o(.init.text+0x54c): In function `sched_init_smp': : undefined reference to `____ilog2_NaN' kernel/built-in.o(.init.text+0x54c): In function `sched_init_smp': : relocation truncated to fit: R_NIOS2_CALL26 ____ilog2_NaN make[2]: *** [.tmp_vmlinux1] Error 1 make[1]: *** [sub-make] Error 2 make[1]: Leaving directory `/home/nick/06212010-nios2-linux/nios2-linux/linux-2.6' make: *** [linux] Error 1  Any help greatly appreciated!  Nick

Nios II supports SMP? That's news to me...

[Altera_Forum]

Any ideas of where to disable this support? I'm only going by the directions given in the Nios Wiki for building this kernel........

hi nipri 

 did you try compile with defalt parameters????? at menuconfig ????     cheers   Franz Wagner

Hello Franz! 

 I am running make menuconfig in the uClinux-dist dir., selecting "Altera" as the vendor and "niosnommu" as the product. Also, making sure that libc is set to "none" and selecting the "Default all setting" option....

I notice there is a NON_SMP_BUILD option in the Makefile but I'm not sure how to invoke it.... make NON_SMP_BUILD=1 doesn't seem to work... 

 I am also noticing that I am getting an error as below... right after the SMP related error... Obviously some sort of a config issue going on here????????  mm/built-in.o(.text+0x12df4): In function `shmem_getpage': : undefined reference to `copy_page' mm/built-in.o(.text+0x12df4): In function `shmem_getpage': : relocation truncated to fit: R_NIOS2_CALL26 copy_page make[2]: *** [.tmp_vmlinux1] Error 1

I am not 100%sure but the NON_SMP_BUILD option acts on the compilation process on your computer and will not affect the embedded system/FPGA design you're building. It simply make the compilation process to avoid parallelization on multiple cores/cpus.

What branch are you using?

[Altera_Forum]

@gabribob: I think your right about the NON_SMP_BUILD option as far as I can tell from the documentation 

 @ykozlov: I downloaded and untarred the 06212010 dist and ran ./checkout so I'm not exactly sure which branch I have... I'm running the update script now... something I didn't do previously....

ok ...... 

  did you set the path ?  PATH=$PATH:/opt/nios2/bin  try make make menuconfig   and make vendor......  report  Franz Wagner
