Compatibility Between version 2.8.1 and 2.95.2

Compatibility Between version 2.8.1 and 2.95.2

[Ang Chin]

Hi,

  When i tried to compile my project with g++ 2.95.2
(previously with g++ 2.8.1, and work fine), i got
error on some header files not found (generic.h,
sysent.h, ...)

  i did a comparison between both version's include
directory, version 2.8.1 has 182 header files, whereas
version 2.95.2 only has 132 header files.

  Where can i find the rest of the header files? OR,
what can i do to resolve this if my project are using
those missing header files?

  One last question, any compatibilities issue between
these two versions?

thanks in advance,
chinhai

Header files are generally in /usr/include, but GCC fixes some of them
that wouldn't compile with GCC or simply that are buggy, and stores
them in its own installation tree.  Those that don't require fixing
remain in /usr/include.  Perhaps you're running GCC on a machine that
doesn't have development header files?

Hi,

  thanks for your info. i have another question:

  i compiled a library in Solaris2.5.1 and work with
example. When i port it to Linux 2.2.16-3smp, and
re-compile it, it create the archive (librw.a), but
when i link it with the previous example, i got the
folowing error,

  % g++ -c test.C
  % g++ -o test test.o -lrw -L(path where librw.a in)
  /usr/pkgs/2.95.2/bin/gld: final link failed: Bad
value
  collect2: ld returned 1 exit status.

  May i know what goes wrong?

thanks,
chinhai

Do you mean you've created the library using a Solaris tool-chain, and
now you're using it on GNU/Linux?  I don't think this is supposed to
work.

hi,

  No, i re-built the library in the Linux machine,
i.e. re-compile the source code in Linux machine to
form the library, then develop an example to link with
the library created. However, i got the below error.
  "...gld: final link failed: Bad value"

Then, it's likely that you've found an assembler or a linker bug.  You
should report it to the maintainers of GNU binutils, after checking
that you've got the latest version of it.
