Compilation Errors

Compilation Errors

[VallabhaN]

Hi All,

     I hitting some compilation errors while compiling a .cpp file. I am using
gcc 3.1 on Red Hat 7.2 (32 bit m/c). The errors says something like;

In file included from /usr/gcc31/include/g++-v3/bits/fpos.h:45,
                 from /usr/gcc31/include/g++-v3/iosfwd:46,
                 from /usr/gcc31/include/g++-v3/streambuf:46,
                 from /usr/gcc31/include/g++-v3/backward/streambuf.h:32,
                 from chatdoc.cpp:14:

/usr/gcc31/include/g++-v3/cwchar:185: `wmemset' not declared


     Anything wrong with my gcc installtion?. Looking at these errors I guess
there is nothing wrong with souce file which I am compiling. Any idea how to
solve this?

Thanks

Hi,

I'm trying to create a shared object file calling GCC using execv, but 
am getting some errors.

First - .o creation, using the following options:

---------------------
-fPIC
-o
/tmp/simpl-so/objs/10.o
-I
/simpl/dev/src
-I
/simpl/dev/src/core
-I
/simpl/dev/src/include
-c
/t/bufout.c
-------------------------

This seems to go ok, then calling with the following options:
-------------------------
-v
-shared
-o
/tmp/simpl-so/objs/10.so
/tmp/simpl-so/objs/10.o
-lsimpl
--------------------------
produces:
============
/usr/bin/ld: /tmp/simpl-so/objs/10.o: relocation R_X86_64_32 against `a 
local symbol' can not be used when making a shared object; recompile

===============

libsimpl is compiled using fPIC too.

I'm using Ubuntu 9.04 64-bit.  It compiled ok on the 32-bit version.

Can anyone give any guidance on how to solve this?

Thanks,

Marcus Clyne.
