RE: GNU APL now requires bash shell and in-tree builds

[Callahan, Brian Robert]

Hi Jürgen --

Per POSIX, bind requires the inclusion of sys/socket.h, so that should be in the includes list for main.cc if there is a call to bind in main.cc. I'm not sure we can or should assume an implicit include from elsewhere.

https://pubs.opengroup.org/onlinepubs/9699919799/functions/bind.html

As for needing the scope-resolution on bind, that is something that someone (i.e., me or Alexander) should look further into.

Hi Alexander,

thanks, fixed in SVN 1470.

The bind() error is somewhat strange because:

- in the same file (main.cc), accept() (a companion of bind()) works without :: and
- in other files bind() also works without ::

I suppose some other #include file declares bind() differently (which
would be an error in the platform).

Best Regards,
Jürgen

Dear list,

I tried out SVN 1468, but still had to modify the following files
*   . /configure (replace "source" with ".")
*   . /src/main.cc (replace "bind" with "::bind" on line 300

Thanks in advance for your help.

Hello --

In fixing Alexander's issue, I found these lines in the GNU APL
Makefile I have never seen before:
buildtag.hh: Makefile buildtag.sh
       source ${top_srcdir}/buildtag.sh
       touch $@

The source command is a bash built-in and won't work on other shells,
like OpenBSD ksh.

Additionally, even with bash, this command does not work if doing an
out-of-tree build, which is the way I have always built GNU APL and
which autotools are supposed to make easy to do.

Thanks.

~Brian
