[ace-users] Regular vs autoconf ACE+TAO builds

[Thomas Girard]

Hello,

(A shortened PRF is appended to this email.)

Here is an update to my earlier posts[1][2] on how to compare regular vs
autoconf builds.

The script used to compare is available at [3]. To use it you must:
1. define $ACE_ROOT
2. launch it with two arguments: platform specific config.h and
configure generated config.h

For instance, on my machine, I used, from $ACE_ROOT directory:
me@machine$ ../ace-cmp.sh ./ace/config-linux.h ../objdir/config.h

I believe running this on different platforms could be a good way to
improve autoconf support and spot missing macros.

On my amd64, Debian GNU/Linux box, I get the output available at [4].

Analyzing first differences (next ones later), we see that in regular
builds the following macros are defined to 1, while they are not using
autoconf:

* ACE_GETNAME_RETURNS_RANDOM_SIN_ZERO
o documented in $ACE_ROOT/ace/README
o used in $ACE_ROOT/ace/OS_NS_sys_socket.inl for:
- ACE_OS::getpeername
- ACE_OS::getsockname
o no autoconf test

* ACE_HAS_ALLOCA_H
o used in $ACE_ROOT/ace/os_include/os_stdlib.h only
to include <alloca.h>, i.e. *not* used
o autoconf test, flag --enable-alloca [no]

* ACE_HAS_BSWAP_{16,32,64}
o ACE_HAS_BSWAP_16 and ACE_HAS_BSWAP_32 used in
$ACE_ROOT/ace/CDR_Base.inl
o typo for ACE_HAS_BSWAP_64 in first occurrence
o no autoconf test

* ACE_HAS_INTEL_ASSEMBLY
o used in :
- $ACE_ROOT/ace/Atomic_Op.cpp
- $ACE_ROOT/ace/CDR_Base.inl
- $ACE_ROOT/ace/CDR_Base.cpp
o no autoconf test

* ACE_HAS_NONCONST_SETRLIMIT
o documented in $ACE_ROOT/ace/README
o used in $ACE_ROOT/ace/OS_NS_sys_resource.inl
o working autoconf test, i.e. error in regular builds

* ACE_HAS_POSIX_MESSAGE_PASSING
o *not* used
o no autoconf test

* ACE_HAS_RECURSIVE_MUTEXES
o used in:
- $ACE_ROOT/ace/OS_NS_Thread.{inl,h,cpp}
- $ACE_ROOT/ace/Recursive_Thread_Mutex.{inl,h,cpp}
o no autoconf test

More analysis later.
Regards,

Thomas

Hi,

Thanks for using the PRF form. Can you store this in bugzilla?

Hi Thomas,

This is great! Could you please work with J.T. to normalize these differences?

Thanks!

Doug
