C++ and Textproc/Groff

[pikpik]

Hi,

I was trying to build "editors/nano" in pkgsrc, but my build failed on
the following messages:

[...]

checking that C++ compiler can compile simple programs... yes
checking that C++ static constructors and destructors are called... no
configure: error: a working C++ compiler is required
*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/textproc/groff

[...]

So, it seems C++ support exists, but is partial with G++. Here's the
most related instance of this I found elsewhere, for NetBSD in this
case: http://mail-index.netbsd.org/port-alpha/2002/11/27/0001.html
From that, it seems the trouble could be with "crtbegin.o,"
"crtend.o," and similar files.

From that NetBSD message, a possibility was that libtool needed to be
rebuilt with newer libraries. Unfortunately, rebuilding and installing
it doesn't seem to help.

Thank you,
pikpik

Hi,

It might not be related but I also get the same when trying to run
configure ddd (see below).

Which version of gcc are you running? Can you try the latest
(gcc-4.4.5)?
ftp://ftp.minix3.org/pub/minix/packages/3.2.0/i386/All/gcc44-4.4.5nb3.tgz

Hi Thomas,

I've just tried it with gcc-4.4.5 and I get the same:(

Did you run "make gnu-includes" and "make elf-libraries" in /usr/src?
And are you running the latest base system, 3.2.0? Can you send the
config.log file from ddd?

Hi Thomas,

Yes, I did run make gnu-includes elf-libraries in /usr/src and the
system I'm using is 3.2.0 (the one which can be downloaded from the
minix3 page). So I'm not tracking current. Please, find the config.log
below.

Hi,

> [config.log]

> error: iostream.h: no such file or directory

It seems that the issue is with the configure script and not Minix's C+
+ compiler. iostream.h is a pre-ISO standard C++ header. As of
gcc-4.3, it was removed ( See http://gcc.gnu.org/gcc-4.3/porting_to.html
). My suggestion is to regenerate the configure script with autoconf
to get a more up to date C++ feature check.

Hi Thomas,

I gave a try to a newer version (mainly because autoreconf also
failed) hoping that the configure script may be different. Actually,
configuring version 3.3.9 goes far beyond than version 3.2.1. However,
it also fails but now with a complaint to libX11.a -even though I
specified the X includes and X libraries explicitly:

#./configure --disable-shared --x-includes=/usr/pkg/X11R6/include/ --x-
libraries=/usr/pkg/X11R6/lib/

I just copy the end of the configure output here -if it's necessary
later I can paste the whole stuff:)

[...]
checking for XOpenDisplay in -lX11... no
configure: error: The X11 library '-lX11' could not be found.
Please use the configure options '--x-includes=DIR'
and '--x-libraries=DIR' to specify the X location.
See the files 'config.log' and 'ddd/config.log'
for further diagnostics.

Any idea why it can't find that lib?
