Gcc3.2 build error on Solaris 10

Gcc3.2 build error on Solaris 10

[Dan Keating]

Hi all,

I'm having problems building gcc3.2 on a solaris 10 system. Gcc2.95.3 builds
fine, but 3.2 and 3.2.3 both fall down with the following error:

/temp/bsm/gcc-sun10/gcc/xgcc -B/temp/bsm/gcc-sun10/gcc/
-B/lang/gcc/3.2/sparc-sun-solaris2.10/bin/
-B/lang/gcc/3.2/sparc-sun-solaris2.10/lib/ -isystem
/lang/gcc/3.2/sparc-sun-solaris2.10/include -DHAVE_CONFIG_H -I.
-I../../../../gcc-3.2/libstdc++-v3/libmath -I.. -g -O2 -c
../../../../gcc-3.2/libstdc++-v3/libmath/signbit.c -o signbit.o
In file included from ../../../../gcc-3.2/libstdc++-v3/libmath/signbit.c:32:
../../../../gcc-3.2/libstdc++-v3/libmath/mathconf.h:84: conflicting types
for `nan'
/usr/include/iso/math_c99.h:145: previous declaration of `nan'

Configure is being run with parameters "--enable-languages=c++
--disable-shared".

Hopefully there's someone who can see a cause for this.

Regards,

Dan

Look at the two files in question:

gcc-3.2/libstdc++-v3/libmath/mathconf.h, line 84
/usr/include/iso/math_c99.h, line 145

Most likely you will see conflicting types for nan.

Since gcc 3.2 is four years old and completely unsupported, your best
bet for fixing this would be to edit mathconf.h to match your system
header file.

Thanks for the reply.

Yes, I am aware what the the error itself is, but I was hoping this was a
known issue, with perhaps a work-around to go with it. Looks like I'm out of
luck on that front.

The gcc3.3 series does build on solaris10, so a move to another series might
be the way to go. However, when you have a legacy of commercial products to
support, it's not always easy to upgrade to the latest and greatest :-)

Best of luck,

Dan

The newer GCCs like gcc-3.4.6 have fixed the 'libmath/mathconf.h' as 
follows:

-------------- clip ------------------------------------
*** mathconf.h Thu Aug 16 15:49:19 2001
--- ../../../gcc-3.4.6/libstdc++-v3/libmath/mathconf.h Fri Jan 23 
18:50:34 2004
***************
*** 79,89 ****
# include <nan.h>
#endif

- #ifndef NAN
- # define NAN (nan())
- double nan (void);
- #endif
-
#ifdef HAVE_IEEEFP_H
# include <ieeefp.h>
#endif
--- 79,84 ----
-------------- clip ------------------------------------

With this patch the error should disappear... But there are other things to
consider like the '*-*-solaris2.10' targets (x86 and sparc) totally 
being missing
from the 'gcc/config.gcc' template and from the libstdc++-v3 configure 
choices!
Assuming the '10' being "similar with the '9'" and these both being 
similar with
the '8', could help things, also the 'solaris2.9' support is missing 
from the 3.2.3
sources. So the beginning of the 'sparc-*-solaris2*' template in 
'gcc/config.gcc'
could be as follows:

-------------- clip ------------------------------------
sparc-*-solaris2*)
tm_file="${tm_file} dbxelf.h elfos.h svr4.h sparc/sysv4.h sparc/sol2.h"
if test x$gnu_ld = xyes; then
tm_file="${tm_file} sparc/sol2-gld.h"
fi
tmake_file="sparc/t-sol2 sparc/t-crtfm"
if test x$gnu_ld = xyes; then
tmake_file="$tmake_file t-slibgcc-elf-ver"
else
tmake_file="$tmake_file t-slibgcc-sld"
fi
case $machine in
*-*-solaris2.[789] | *-*-solaris2.1[0-9])
tm_file="sparc/biarch64.h ${tm_file} sparc/sol2-bi.h"
if test x$gnu_ld = xyes; then
tm_file="${tm_file} sparc/sol2-gld-bi.h"
fi
if test x$gas = xyes; then
tm_file="${tm_file} sparc/sol2-gas-bi.h"
fi
tmake_file="$tmake_file sparc/t-sol2-64"
;;
esac
-------------- clip ------------------------------------

and the 'libstdc++-v3/configure.target' have :

-------------- clip ------------------------------------
irix6.5)
os_include_dir="config/os/irix/irix6.5"
;;
mingw32*)
os_include_dir="config/os/mingw32"
;;
netbsd*)
os_include_dir="config/os/bsd/netbsd"
;;
solaris2.5*)
os_include_dir="config/os/solaris/solaris2.5"
;;
solaris2.6*)
os_include_dir="config/os/solaris/solaris2.6"
;;
solaris2.7* | solaris2.8* | solaris2.9* | solaris2.10*)
os_include_dir="config/os/solaris/solaris2.7"
;;
-------------- clip ------------------------------------

for defining the 'os_include_dir' being right....

This latter file was fixed years ago when producing crosstools for
Solaris8, and it can be that these choices were originally in the
'configure.in' there but were moved to the 'configure.target' for
some 'compatability' reasons (other similar choices were there?).
In any case "something should be done" in there to get this thing
right...

Unfortunately it took this long for me to look at this, fix what should
be fixed, and produce the tools (maybe a week ago), and to remember
telling these things :-(

[Bill McEnaney]

Hey, Folks,

I think my Sunblade 100, which runs Solaris 8, has built Gcc3.2.  So if
anybody wants me to try to build it, I'll be happy to do that.  Sadly,
the poor ol' guy is a slow poke, who probably thinks aslmost as slowly
as my spastic fingers type.  :)  Since Tamino, the workstation, has
tured six this month, he;s a senior citizen.  ;)

RE: Gcc3.2 build error on Solaris 10

[Dan Keating]

Hi Bill,

Thanks for the offer, but we've already confirmed GCC3.2 builds ok on our
Solaris 8/9 systems (we've got a few senior citizens of our own doddering
about the place). It seems Solaris10 has modified it's systems headers
sufficiently to break the GCC3.2.x build, but it would be nice if someone
out there with solaris10 could double check to see if it is really Solaris10
or just our system. 

However, seeing as this release is years behind the current curve, it could
be a wake-up for us to update our compilers, as has already been hinted.
Painful, but perhaps time?

Cheers,

Dan

RE: Gcc3.2 build error on Solaris 10

[Bill McEnaney]

Hi, Dan,

Although I haven't timed Tamino when he's been building Gcc, the poor
guy takes hours to do that.  I'll launch a build at midnight, only to
hear the ol' fellow still clinking, clanking, and clunking at about
11:00 the next morning.  But I still upgrade to the latest gcc each time
a new release come out.  I don't need the newest electronic gadget.  If
I did, Tamino would already be in computer heaven.  I do like to keep
the newest versions of my coompilers, though, especially the ones for
Prolog, Haskell, and Lisp.

Cheers,
Bill
