We're busily working on porting the
Archiver to R3.14 and fixing the
index and other shortcomings.

Hello:

Let me quickly outline my system configuration:
----
Epics version: 3.13.9
ChannelArchiver version: 1.9.1
OS: RedHat9 ( kernel 2.4.20)
gcc version from running 'gcc -v':
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
----

I was wondering whether anyone has been using the ChannelArchiver under RedHat9. I am having a few minor compilation issues which I believe may be related to my version of gcc.

Essentially the problem is due to a line (in two different files):

_file.unsetf (std::ios::binary);

where _file is an object of type std::ifstream. The error I get is:

In file included from ../ASCIIParser.cc:6:
..../ASCIIParser.cpp: In member function `bool ASCIIParser::open(const
stdString&)':
..../ASCIIParser.cpp:25: no matching function for call to `
std::basic_ifstream<char, std::char_traits<char>

::unsetf(const

std::_Ios_Openmode&)'
/usr/include/c++/3.2.2/bits/ios_base.h:361: candidates are: void
std::ios_base::unsetf(std::_Ios_Fmtflags)
gmake[1]: *** [ASCIIParser.o] Error 1
gmake[1]: Leaving directory `/usr/local/epics_versions/epics3.13.9GEM8.5/extensions/src/Tools/O.Linux'
gmake: *** [install.Linux] Error 2


I can comment out this line and everything compiles fine. It seems like the library interface has changed and one cannot set the bits responsible for binary processing after the stream has been opened.

I would imagine that this line makes very little difference on linux, but I am curious whether other people perhaps with other versions of gcc have experienced this. For the sake of consistency I would like modify the code as little as possible (preferably not at all).

Also, does anyone know what the *official* web page for the archiver is? I found most information on:

http://lansce.lanl.gov/lansce8/Epics/Archiver/

and:

http://ics-web1.sns.ornl.gov/~kasemir/archiver/ <http://ics-web1.sns.ornl.gov/%7Ekasemir/archiver/>

which has source for version 2.1.0 (which should be used with EPICS 3.14.x).

Thanks.
