Thanks for the tip. I was trying to rebuild the toolchain with crosstool-ng after changing the minimum kernel version, however this time I’m getting this error:
[CFG ] *** These critical programs are missing or too old: as ld gcc make [CFG ] *** Check the INSTALL file for required versions. [ERROR] [ERROR] >> [ERROR] >> Build failed in step 'Installing C library headers & start files' [ERROR] >> called in step '(top-level)' [ERROR] >> [ERROR] >> Error happened in: CT_DoExecLog[scripts/functions@257] [ERROR] >> called from: do_libc_backend_once[scripts/build/libc/glibc.sh@348] [ERROR] >> called from: do_libc_backend[scripts/build/libc/glibc.sh@153] [ERROR] >> called from: do_libc_start_files[scripts/build/libc/glibc.sh@70] [ERROR] >> called from: main[scripts/crosstool-NG.sh@646] [ERROR] >> [ERROR] >> For more info on this error, look at the file: 'build.log' [ERROR] >> There is a list of known issues, some with workarounds, in: [ERROR] >> '/usr/local/share/doc/crosstool-ng/crosstool-ng-1.20.0-361-g85f9814/B - Known issues.txt' [ERROR] [ERROR] (elapsed: 29:01.89) I can’t seem to figure out what is causing this, I was able to build it successfully before.

If you look at gem5/src/arch/arm/linux/process.cc<http://process.cc>, you will see that in 32-bit mode the emulated syscall returns "3.0.0" and in 64, "3.7.0+". When you configured the toolchain in crosstool-ng, there is an option "CT_LIBC_GLIBC_MIN_KERNEL_VERSION". If that's greater than what the emulated uname() reports, glibc will fatal(). -----"gem5-users" <gem5-users-boun...@gem5.org<mailto:gem5-users-boun...@gem5.org>> wrote: ----- To: gem5 users mailing list <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> From: "Ejjeh, Adel" Sent by: "gem5-users" Date: 11/18/2015 12:46PM Subject: [gem5-users] FATAL: Kernel to old Hi all. I am trying to generate some simulation statistics by running an application on an ARM core simulation in gem5. I used crosstool-ng to build the cross-gcc compiler and then I used that to compile the application I want to run as well as it’s needed library. After that, when i tried to run the gem5 simulation in SE mode, I got the following error: **** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... FATAL: kernel too old warn: ignoring syscall rt_sigprocmask(1, ...)

I read somewhere that this has to do with the version of glibc (Specifically that the one I used in the compilation is newer than the one supported in gem5 or something like that.) Any ideas?
