Zhen,
Congratulations on possibly the most complete gems-users post I have ever seen.

Now, to address your issue...

1. Make sure you have properly set all paths. The failed mkdir is in the 'build the simics library' portion of the build, which is basically out of our hands and run entirely by Simics. It can fail when a path isn't properly set or Simics isn't properly configured.

2. You're going to want to use g++ in some form, not gcc, to compile everything. That could be causing your Ruby build issue. Otherwise, you may have found a bison+flex+gcc version combination that don't like each other. (All those *AST's are autogenerated garbagecode).

Regards,
Dan

Hi,

I'm new to GEMS and Simics. I installed GEMS 2.1.1 and Simics 3.0.31 following instructions on http://www.cs.wisc.edu/gems/doc/gems-wiki/moin.cgi/Setup_for_Simics_3.0.X and the GEMS-Ubuntu instructions. I got compile error on both Ruby and Opal.

The Ruby compile error is similar to https://lists.cs.wisc.edu/archive/gems-users/2006-February/msg00042.shtml , they solve the problem by reinstalling the GEMS, no real solution found. I restalled the GEMS following all the instructions carefully, still same problem. Other post of the compile errors seem to be different from my case.

The Opal compile error is shorter. I got permission denied on creating directory in /obj/. Is this related to some path setting?

The system is Debian lenny 2.6.26, x86.
gcc version 3.4 (the system also has gcc-4.3, 4.2, 4.1, but I already export CC=gcc-3.4 and changed the versions in those Makefiles. g++ version is 4.3.2, I don't know whether this matters. I changed the CC path setting to /usr/bin/gcc-3.4 in Makefiles.common already. Originally, it was set to /usr/bin/g++.)
bison version 2.3
flex version 2.5.35

The detailed error message is attached here. Any idea how to solve this?
