gcc is not responding

[Rudra Banerjee]

dear friends,
due to some unknown reason, i cant invoke gcc from my account. its not really troublling the machine, but if I invoke gcc/g++/ifort to compile any program, its not doing anything. gcc is specially making the terminal inactive. here is ps -aux output of gcc -v.

if it is needed, my system is :
Linux xxx.lan.yyy.res.in 2.6.23.1-42.fc8 #1 SMP Tue Oct 30 13:55:12 EDT 2007 i686 i686 i386 GNU/Linux
can yoou tell me what is going wrong?

Hallo,
I'm writing because I have written a small program targeted for the
Microchip PIC uC architecture and i haven't find any port of gcc for
PICs.
My questions are:
-Has someone started to work around this port?
-It is possible to port gcc for these chips?

I have contact gnu.org and asked them if I can try to start working for
this, and they told me to contact you before doing anything, can you
help me (I absolutely need gcc to compile my code)?

Thanks.
Ilia Platone.


Hello,

I get the following result when i ldd my shared library in a target computer:

$> ldd /usr/lib/libCVTJavaInterface.so
/usr/lib/libCVTJavaInterface.so:
/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by
/usr/lib/libCVTJavaInterface.so)
    linux-gate.so.1 =>  (0xffffe000)
    libcvt.so => /usr/lib/libcvt.so (0xb7e95000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7dab000)
    libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7d84000)

    /lib/ld-linux.so.2 (0x80000000)


I have the following files in the target computer:
lrwxrwxrwx 1 root root     18 2007-10-17 10:00 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.8
-rw-r--r-- 1 root root 929648 2007-03-02 21:51 /usr/lib/libstdc++.so.6.0.8

I have the following files in my development computer:
gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
/usr/lib/libstdc++.so.5 -> libstdc++.so.5.0.7
/usr/lib/libstdc++.so.5.0.7
/usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.9
/usr/lib/libstdc++.so.6.0.9

What can i do?

One option i think is to static compile the libstdc++ library in my shared library. what is the instruction to do that?

thanks in advance,
Herbert

With symbol versioning, compatibility works backwords but not forwards
-- a binary built against an older libstdc++ should normally function
correctly with a newer libstdc++ found on the machine at runtime.  Thus
the solution is to install the oldest version of gcc you wish to support
on your development machine and link with it.  This doesn't mean you
necessarily need to use this old version of gcc to develop with, as you
can have as many versions installed on the machine as you want.  Just
use the old version to produce the final binary.

That's a very bad idea.  Static linking works well for programs, but for
a shared library it's going to be a nightmare because it means your lib
will be loaded into a program that is likely dynamically linked against
some other version of libstdc++.  Thus you get essentially two copies of
libstdc++ code, and if you try to pass objects between your code in your
shared library and the code in the main program you have to ensure that
all data structures are laid out exactly the same or compatible,
otherwise you get random crashes or other unexplainable behavior.  In
other words, this solves nothing but just makes the problem ten times
harder to debug.  Not to mention the practical issue that the code in
the static libstdc++ archive is not built PIC and so you can't link it
into a shared library (the exception being i386, where it's allowed but
with a performance penalty of relocs that make your text section
non-sharable so what's the point.)
