Aolserver Installation With Google Performance Tools

Aolserver installation with Google Perftools System: Red Hat Enterprise Linux ES release 4 (Nahant Update 4) Dual-Core AMD Opteron(tm) Processor 2210 HE 3 GB memory Software : aolserver-4.0.10-src.tar.gz or aolserver-4.5.0-src.tar.gz Google perftools 0.8 tcl8.4.14-src.tar.gz Installation : Google perftools installation : # mkdir ~/software # cd ~/software # wget http://google-perftools.googlecode.com/files/google-perftools-0.8.tar.gz # tar xzf .tar.gz # cd google-perftools-0.8 # ./configure --prefix/home/atif/googlelib # make it gave an error src/base/linux_syscall_support.h:339: error: invalid conversion from `long int' to `void*' make: *** [libtcmalloc_minimal_la-malloc_hook.lo] Error 1 open src/base/linux_syscall_support.h and edit line 338 Change this

To this

static inline _syscall6(void*, sys_mmap, void*, s, size_t, l, int, p, int, f, int, d,

static inline _syscall6(long int, sys_mmap, void*, s, size_t, l, int, p, int, f, int, d,

after that # make clean # make # mkdir /home/atif/googlelib # make install I also added in LD_LIBRARY_PATH the location /home/atif/googlelib/lib , in fact i even added it in /etc/ld.so.conf and ran . make sure you have LD_LBRARY_PATH in your ~/.bash_profile export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/atif/googlelib/lib

# ldconfig TCL installation: # mkdir ~/tcl # cd ~/software # wget http://surfnet.dl.sourceforge.net/sourceforge/tcl/ # tar xzf tcl8.4.14-src.tar.gz # cd tcl8.4.14/unix # ./configure --prefix=/home/atif/tcl --enable-threads export the tcl library location in your LD_LIBRARY_PATH put this line in bash_profile if using bash. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/atif/tcl/lib We want tcl to use google tcmalloc() for thread allocation so we will enable thread support but disable thread allocation from tcl. create a simple bash script named disablealloc.sh cd ./unix && \ cat Makefile | sed -e 's/-DUSE_THREAD_ALLOC=1//' > Makefile.new && \ cat tclConfig.sh | sed -e 's/-DUSE_THREAD_ALLOC=1//' > tclConfig.sh.new&& \ cp Makefile.new Makefile && \ cp tclConfig.sh.new tclConfig.sh All this does is to change two files and removes -DUSE_THREAD_ALLOC=1 from each file . Save this script in ~/tcl #cd /home/atif/tcl # sh disablealloc.sh after that # make # make install Aolserver installation : Aolserver 4.0.10: # mkdir ~/aol40 # cd ~/software/ # wget http://ovh.dl.sourceforge.net/sourceforge/aolserver/aolserver-4.0.10-src.tar.gz # tar xzf aolserver-4.0.10-src.tar.gz # cd aolserver-4.0.10

-- if you are compiling on redhat enterprise 3 on a 64 bit platform like amd opteron change the nsd/tclobj.c and comment out following lines , line 88

(On redhat enterprise 4 this is not needed) Change this

To this

if (sizeof(int) < sizeof(long)) { Tcl_Panic("NsTclInitObjs: sizeof(int) < sizeof(long)"); }

/*
