Not sure I can help Bob, but perhaps I can help Dean.  Solaris is very
picky about string operations.
Basically you have to check each string and make sure it is not null or
that you are not using a null pointer or it will core.
For the port to Solaris from AIX, NetView development had to replace all
the standard string operations with ones that checked the length and
pointers first.

Hope this helps

LOL!!!

Sorry Bob, but I have been working on a small app to convert a 32-bit
decimal word to an IP address for over a week.  I blew the thing together
under Windows, but as I am working on it under Solaris, I am having all
kinds of problems with basic commands that should work (strcat, strcpy), I
keep getting a Coredump... I wonder if this only happens with gcc and not
the Sun's C for Solaris.

(sorry this is off topic)

Dean

Help!

I've written a C++ app that integrates with NetView
5.1 under AIX and Solaris. When I build (with gcc) and
run in on AIX 4.2.x, no problems. When I build on
Solaris 2.5.1 w/ gcc-2.95.1, I have problems (I've
also tried on 2.8 w/ gcc-2.95.3 and I get the same
errors).

Specifically, I get several warnings during the link
phase. I usually don't worry about warnings, however,
the app does not work as expected when I run it (it
does however work just fine under AIX).

Here are the details:

I compile and link with:

"c++ -DNDEBUG -D_REENTRANT -fpermissive -g -I. I../usr/OV/include
-L../usr/OV/lib
-L/usr/openwin/lib -L/usr/ucblib -R/usr/OV/lib
MyProgram.cpp -lovsnmp -lovw -lov -lnsl -ldl
-lkstat -lw -lposix4 -lpthread"

Here's an example of the warnings I get:

"ld: warning: symbol `bad_exception virtual table' has differing sizes:
(file ../usr/OV/lib/libovw.so value=0x18;
file /usr/local/lib/gcc-lib/sparc-sun-
solaris2.5.1/2.95.1/libgcc.a(exception.o) value=0x20);
/usr/local/lib/gcc-lib/sparc-sun-
solaris2.5.1/2.95.1/libgcc.a(exception.o)
definition taken"

One other thing: I only get these errors when I use
STL containers such as map or list.

I know this question is in a gray area between being a
NetView or gcc question, but I've already posted to
the gcc newsgroup with no responses and I'm getting
desparate.

If anyone out there has an idea on how I can resolve
this, I would greatly appreciate it.

TIA,

Bob
