Compile and Debug SPEC CPU2006 in Linux

Jun 12, 2016

SPEC CPU 2006是一个比较老的benchmark，所以在较新的Linux系统上编译会出现不兼容的问题。在编译过程中，需要对SPEC CPU 2006的源代码做几处修改来兼容新的Linux系统。本文以CentOS 7系统为例，介绍在Linux系统中SPEC CPU 2006的编译过程。

Compile

首先，由于兼容性问题SPEC CPU 2006中自带的install.sh文件是运行不了的，我们需要重新编译源代码。进入/tool/src目录，运行buildtools文件：

./buildtools

Debug

运行过程中，会出现几个错误。下面列出了这几个错误和相应的解决方法。

  1. error building specmd5sum

    编译specmd5sum时，会出现如下错误：

     gcc -DHAVE_CONFIG_H    -I/home/gem5/cpu2006/tools/output/include   -I. -Ilib  -c -o md5sum.o md5sum.c
 In file included from md5sum.c:38:0:
 lib/getline.h:31:1: error: conflicting types for 'getline'
  getline PARAMS ((char **_lineptr, size_t *_n, FILE *_stream));
  ^
 In file included from md5sum.c:26:0:
 /usr/include/stdio.h:678:20: note: previous declaration of 'getline' was here
  extern _IO_ssize_t getline (char **__restrict __lineptr,
             ^
 In file included from md5sum.c:38:0:
 lib/getline.h:34:1: error: conflicting types for 'getdelim'
  getdelim PARAMS ((char **_lineptr, size_t *_n, int _delimiter, FILE *_stream));
  ^
 In file included from md5sum.c:26:0:
 /usr/include/stdio.h:668:20: note: previous declaration of 'getdelim' was here
   extern _IO_ssize_t getdelim (char **__restrict __lineptr,
                      ^
 make: *** [md5sum.o] Error 1
 + testordie 'error building specmd5sum'
 + test 2 -ne 0
 + echo '!!! error building specmd5sum'
 !!! error building specmd5sum
 + kill -TERM 1299
 + exit 1
 !!!!! buildtools killed

    错误原因主要是：函数冲突，stdio.h库已经定义getline和getdelim函数，而SPEC CPU 2006中的getline.h中也定义了这两个函数。

    解决方法：打开./tools/src/specmd5sum/md5sum.c文件，注释掉getline.h头文件（第38行）

     //#include "getline.h"

  2. error building Perl

    编译Perl时，会出现如下两个错误。

    ERROR 1:

     collect2: error: ld returned 1 exit status
 make: *** [miniperl] Error 1
 + testordie 'error building Perl'
 + test 2 -ne 0
 + echo '!!! error building Perl'
 !!! error building Perl
 + kill -TERM 15173
 + exit 1
 !!!!! buildtools killed

    ERROR 2:

     t/op/sprintf..............................FAILED--no leader found
 t/op/sprintf2.............................FAILED--expected 263 tests, saw 3

    错误原因：

    1) 高版本的Linux内核中删除了asm/page.h头文件;

    2) 配置perl时，需要用到数学库;

    解决方法：

    1) 打开./tools/src/perl-5.8.8/ext/IPC/SysV/SysV.xs文件，注释asm/page.h头文件（第7行）

     //#   include <asm/page.h>

    2) 打开./tools/src/buildtools文件，在编译perl的代码部分（第333行和334行）做如下修改。

    修改前：

     LD_LIBRARY_PATH=`pwd`
 DYLD_LIBRARY_PATH=`pwd`
 export LD_LIBRARY_PATH DYLD_LIBRARY_PATH
 ./Configure -dOes -Ud_flock $PERLFLAGS -Ddosuid=undef -Dprefix=$INSTALLDIR -Dd_bincompat3=undef -A ldflags=-L${INSTALLDIR}/lib -A ccflags=-I${INSTALLDIR}/include -Ui_db -Ui_gdbm -Ui_ndbm -Ui_dbm -Uuse5005threads ; testordie "error configuring perl"

    修改后：

     LD_LIBRARY_PATH=`pwd`
 DYLD_LIBRARY_PATH=`pwd`
 ./Configure -Dcc="gcc -lm" -Dlibpth='/usr/local/lib64 /lib64 /usr/lib64' -dOes -Ud_flock $PERLFLAGS -Ddosuid=undef -Dprefix=$INSTALLDIR -Dd_bincompat3=undef -A ldflags=-L${INSTALLDIR}/lib -A ccflags=-I${INSTALLDIR}/include -Ui_db -Ui_gdbm -Ui_ndbm -Ui_dbm -Uuse5005threads ; testordie "error configuring perl"
