[OpenSIPStack] Caveats in solaris 10 compilation

[Ryan C. <rco...@so...>]

Hello Joegen,

Here are some problems that I encounter when compiling opensipstack and 
opensbc in solaris.

-- GCC version : 3.4.3
-- Operating System: Solaris 5.10 x86

1. Compiling opensbc encounter errors regarding -x03 flag in g++

**********LOG

g++ -DP_USE_PRAGMA -D_REENTRANT 
-I/export/home/joegen/opensipstack/include -Wall  
-I/export/home/joegen/opensipstack/include -xO3  -DSOLARIS -DUSE_GCC  -c 
../common/vfakeio.cxx -o 
/export/home/joegen/opensipstack/lib/obj_solaris_x86_r/vfakeio.o
g++: ../common/vfakeio.cxx: No such file or directory
g++: warning: `-x O3' after last input file has no effect
g++: no input files

**********SOLUTION

modify opensipstack/make/unix.mak and find the piece of code below

ifneq ($(OSTYPE),Darwin)
  ifeq ($(OSTYPE),solaris)
    OPTCCFLAGS  += -xO3
  else
    OPTCCFLAGS  += -Os
  endif
else
  OPTCCFLAGS    += -O2
endif

modify the line OPTCCFLAGS  += -xO3 to OPTCCFLAGS  += -O3





2. It is using cc as a default C compiler but my system does not have cc 
installed

**********LOG

cc -DSOLARIS -DUSE_GCC -DP_USE_PRAGMA -D_REENTRANT 
-I/export/home/joegen/opensipstack/include -Wall  
-I/export/home/joegen/opensipstack/include -c ../common/getdate.tab.c -o 
/export/home/joegen/opensipstack/lib/obj_solaris_x86_r/getdate.tab.o
make[3]: cc: Command not found

**********SOLUTION

change CC value into gcc during make

bash-3.00$ make optnoshared CC=gcc




3. Compiling opensbc encounter undefined symbol. Below are the error 
during compilation.

obj_solaris_x86_r/opensbc

**********SOLUTION

during configuration, opensipstack is unable to detect video support. To 
be able to fix this we need to tell the configure that we will be using 
a plugin.

bash-3.00$ ./configure --enable-plugins




4. When you access the http of OpenSBC and click any of the links, 
OpenSBC causes an assertion and exit.

**********SOLUTION

The problem here is that the configure is unable to check properly if 
the PThreads has support for recursive mutex.
First we need to update the code below in configure.ac

dnl ########################################################################
dnl check for recursive mutexes
P_HAS_RECURSIVE_MUTEX=0
AC_MSG_CHECKING(if recursive mutexes are available)
AC_TRY_COMPILE([#include <pthread.h>],
               [pthread_mutexattr_t attr; 
pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE_NP);], 
P_HAS_RECURSIVE_MUTEX=1)
if test ${P_HAS_RECURSIVE_MUTEX} = 1 ; then
  AC_MSG_RESULT(yes)
else
  if test ${OSTYPE} == Darwin ; then
    AC_TRY_COMPILE([#include <pthread.h>],
                           [pthread_mutexattr_t attr; 
pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE);], 
P_HAS_RECURSIVE_MUTEX=1)
    if test ${P_HAS_RECURSIVE_MUTEX} = 1 ; then
      AC_MSG_RESULT(yes)
    else
      AC_MSG_RESULT(no)
    fi
  else
    AC_MSG_RESULT(no)
  fi
fi
AC_DEFINE_UNQUOTED(P_HAS_RECURSIVE_MUTEX, ${P_HAS_RECURSIVE_MUTEX})


The PTHREAD_MUTEX_RECURSIVE_NP is not defined in pthreads.h in solaris 
10, it is actually defined as PTHREAD_MUTEX_RECURSIVE. So we need to add 
another
validation  after checking if $(OSTYPE) == Darwin. Below is my update in 
configure.ac

...
   if test ${OSTYPE} == Darwin ; then
    AC_TRY_COMPILE([#include <pthread.h>],
                           [pthread_mutexattr_t attr; 
pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE);], 
P_HAS_RECURSIVE_MUTEX=1)
    if test ${P_HAS_RECURSIVE_MUTEX} = 1 ; then
      AC_MSG_RESULT(yes)
    else
      AC_MSG_RESULT(no)
    fi
  elif test ${OSTYPE} == solaris ; then
    AC_TRY_COMPILE([#include <pthread.h>],
                           [pthread_mutexattr_t attr; 
pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE);], 
P_HAS_RECURSIVE_MUTEX=1)
    if test ${P_HAS_RECURSIVE_MUTEX} = 1 ; then
      AC_MSG_RESULT(yes)
    else
      AC_MSG_RESULT(no)
    fi
  else
    AC_MSG_RESULT(no)
  fi
...


Then update the affected file in opensipstack which is in 
opensipstack/src/pwlib/src/ptlib/unix/tlibthrd.cxx and find this piece 
of code

#if  defined(P_QNX) && (P_HAS_RECURSIVE_MUTEX == 1)
#define PTHREAD_MUTEX_RECURSIVE_NP PTHREAD_MUTEX_RECURSIVE
#endif
#if defined(P_MACOSX) && (P_HAS_RECURSIVE_MUTEX == 1)
#define PTHREAD_MUTEX_RECURSIVE_NP PTHREAD_MUTEX_RECURSIVE
#endif

and update it into this

#if ( defined(P_QNX) || defined(P_SOLARIS) ) && (P_HAS_RECURSIVE_MUTEX == 1)
#define PTHREAD_MUTEX_RECURSIVE_NP PTHREAD_MUTEX_RECURSIVE
#endif
#if defined(P_MACOSX) && (P_HAS_RECURSIVE_MUTEX == 1)
#define PTHREAD_MUTEX_RECURSIVE_NP PTHREAD_MUTEX_RECURSIVE
#endif


After modifying configure.ac and tlibthrd.cxx, run again the autoconf to 
update our configure. Then we need to use the internal Regex of 
opensipstack due to it has problems with the latest Regex. So execute 
again the configure like this.

bash-3.00$ ./configure --enable-plugins --enable-internalregex

then we should be able to run opensbc without a problem



thats all
