I obvoiously did something wrong ... I can compile C, but not C++
 
 
Please, HELP!

When I compile hpijs-1.4.1, I had to change some as follows:

1) add the function as suggested by Peter Bosch from bell-labs

to the file which contains main() function,

// Ugly, G++ for Plan 9 needs to be installed correctly.
void
ctors(void)
{
	typedef void (*func_ptr)(void);
	extern func_ptr ___CTOR_LIST__[];

	for (int i = 0; i != (int)___CTOR_LIST__[0]; i++)
		___CTOR_LIST__[i + 1]();
}

and and in the top of the main function call the function:

	ctors();

2) in my case I had to add two functions to vsnprintf() and snprintf() to libc library.
 then, I copied snprintf.c and vsnprintf.c files from /sys/src/ape/lib/ap/stdio to
/sys/src/gnu/ape/libc/stdio.   You may also want to add two lines for those two
functions into /sys/include/gnu/stdio.h like:

extern int snprintf(char *, size_t, const char *, ...);
extern int vsnprintf(char *, size_t, const char *, va_list);

Of course you have to change /sys/src/gnu/ape/libc/stdio/mkfile, too.

3) then, recompile /386/lib/gnu/libc.a.   Don't forget to ranlib to it.
You may want to add some neccessary files which I forgot.   I remember
it was neccessary to recompile the library.

It was adding three files to /sys/src/gnu/ape:
1) mkconfig
# global include file for the APE environment

< /$objtype/mkfile		# gives (compiler loader extension ranliber)
APEBIN=/$objtype/bin/gnu/ape	# where installed ape binaries go
APELIB=/rc/bin/gnu/ape		# where helper programs go
CC=gcc				# compiler (must be ansi)
LD=gcc				# loader
AS=as
CFLAGS=				# global defaults
FAMILY=plan9
AR=ar				# manipulating libraries
RANLIB=echo			# for updating libraries

INSTALL=$APELIB/install		# install script
INSOWNER=()			# default installation parameter
INSGROUP=bin			# default installation parameter
INSMODE=775			# default installation parameter
2) mkfile
</$objtype/mkfile

DIRS=lib9 libbsd libc libl libnet libregexp libv

none:V:
	echo mk all, install, installall, clean, or nuke

all clean nuke install installall:V:
	for (i in $DIRS) @{
		cd $i
		mk $target
	}
3) mksyslib
AFLAGS=

all:V:	$LIB

$LIB:V:	$OFILES			# force archive even when not neede
	ar vu $LIB $newprereq

&:n:	&.$O
	ar vu $LIB $stem.$O

%.$O:	$HFILES			# don't combine with following %.$O rules

%.$O:	%.c
	$CC $CFLAGS $stem.c
	mv $stem.o $stem.$O

%.$O:	%.s
	$AS $AFLAGS $stem.s

install:V: $LIB

installall:V:
	for(objtype in $CPUS) mk install

%.all:V:
	for(objtype in $CPUS) mk $stem

%.installall:V:
	for(objtype in $CPUS) mk $stem

clean:V:
	rm -f *.[$OS] [$OS].out $CLEANFILES

%.clean:V:
	rm -f $stem.[$OS] [$OS].$stem $stem.acid $stem

nuke:V:
	rm -f *.[$OS] [$OS].out $CLEANFILES

%.acid: %.$O $HFILES
	$CC $CFLAGS -a $stem.c >$target

update:V:
	update $UPDATEFLAGS $UPDATE

Those I copied from somewhere, and make small changes, but I forgot it.
