i have encountered some problems with sun studio 9 (version 8 always
worked for me).
obviously it does not like my linker flags ...

when running the following script I get ...

#!/bin/sh

LD_LIBRARY_PATH=/opt/sfw/lib:/usr/local/lib:$LD_LIBRARY_PATH
# PATH=/opt/SUNWspro/bin/:/opt/sfw/bin:$PATH:/usr/ccs/bin
PATH=/usr/ccs/bin/:/opt/SUNWspro/bin/:/opt/sfw/bin::/usr/sbin:/usr/bin

gmake distclean
CC='/usr/ucb/cc'

export CC
export PATH
export LD_LIBRARY_PATH

../configure --prefix=/usr/local/pgsql --disable-rpath --enable-debug
--without-readline --without-gnu-ld

the right compiler and linker are chosen ...

checking whether we are using the GNU C compiler... no
checking whether /usr/ucb/cc accepts -g... yes
configure: using CFLAGS=-v -g
checking whether the C compiler still works... yes
checking how to run the C preprocessor... /usr/ucb/cc -Xa -E
....
checking for flex... /opt/sfw/bin/flex
checking whether ln -s works... yes
checking for non-GNU ld... /usr/ccs/bin//ld
checking if the linker (/usr/ccs/bin//ld) is GNU ld... no
checking for ranlib... ranlib


running gmake will leave me with an error ...

configure will still find the right path to the linker by the way ...

does anybody know how to fix that problem?

best regards,

We've seen that before. Apparently there are some versions of Sun's
compiler that are too stupid to reduce this constant expression to a
constant. File a bug with Sun.

As Tom pointed it this is truly a compiler bug of zthe compiler included
in Sun Studio 9. It seems as if Sun is attempting to fix that.

Here is a test case which will fail on Sun CC 5.6.

#include <stddef.h>
#include <stdio.h>

typedef struct {
int s1;
char data[10];
unsigned char bits[1];
} Ss;

int main(int argc, char **argv){
struct {
int ap;
char data[offsetof(Ss,bits)];
}s1;

printf("offsetof: %d, sizeof %d\n",
offsetof(Ss, bits),
sizeof(s1.data));
return 0;
}


When I'm using Studio 9 cc, compilation failed:
>/opt/F9/SUNWspro/bin/cc -V -Xa -o test test.c
cc: Sun C 5.6 2004/07/15
acomp: Sun C 5.6 2004/07/15
"test.c", line 14: member can not have variably modified type: data
cc: acomp failed for test.c


8.0.0 compiles now with --disable-spinlocks.

When spinlocks are enabled we will see one more problem ...

The nice thing is: This error is not documented and we have not found a
flag to preserve /tmp/yabeAAAQ.aaFl (which makes this error very useful).

google does not contain information about this issue because all four
sites I have found are down.

Has anybody ever seen something like that before?

Hans
