Issues while compiling Zsim on linux x86-64

[sparsh0mittal]

I get the following 2 errors:
/usr/bin/ld: cannot find -lpthread
build/opt/virt/patchdefs.h:41:1: error: ‘SYS_getcpu’ was not declared in this scope

I tried to search on internet, but could not resolve. Here is the detailed log:

You have a linker problem here which is unrelated to zsim. You either have not installed libpthread.a or you don't have it in your path or a softlink might be messed up. There should be tons of hits on google. Try locating libpthread first and check that its path is known by the linker.
Check that you are running a recent version of Ubuntu and that you have installed all dependencies, in this case there shouldn't be any problems.
The sys_getcpu problem suggests that you are running an old version of your OS - please see the requirements of zsim and update.

Thanks for the hints.

The version.h file is generated as follows

#define ZSIM_BUILDDATE "Wed Apr 30 14:30:22 EDT 2014"\n#define
ZSIM_BUILDVERSION "master:10:a8c417b:4fc 10+ 4- 563ecf2c"

I think \n should be executed, not printed as such.

Can you please give more hints on SYS_getcpu. I commented that line and it
compiles and runs, but I want to fix that. My computer is
Scientific Linux release 6.5 (Carbon) 2.6.32-358.23.2.el6.x86_64 #1 SMP Wed
Oct 16 11:13:47 CDT 2013 x86_64 x86_64 x86_64 GNU/Linux

The sys_getcpu problem suggests that you are running an old version of your
OS - please see the requirements of zsim and update.

Thanks and Regards

Some old versions of glibc apparently don't define SYS_getcpu, even though it's a valid syscall. Try adding #define SYS_getcpu (168) to the code. No guarantees it'll work though, you should update to a more recent kernel & glibc if possible.

For the \n, try either using /bin/echo or echo -e in SConstruct... you seem to be using an echo that doesn't grok the newline.

Thanks a lot for your reply.

It compiled well with SYS_getcpu definition you told.

Thanks and Regards
