Hello

I have tried to build octave 3.2.2  with libstdc++_s.a by GCC-4.4.0 (MinGW 
Official) .

With very tricky way, I have got a successful result.

I hacked Makefile in liboctave and src to add -lstdc++_s flag at the end of 
linker flag.
For octave.exe it went well

g++ -shared-libgcc -D_DLL -DPIC -Ic:/Programs/OctaveBuild/include

-lgfortranbegin -lgfortran -lmingw32 -lmoldname -lmingwex -lmsvcrt -luser32 
-lkernel32
-ladvapi32 -lshell32 -lstdc++_s

However, for liboctave.dll, liboptinterp.dll and *.oct file, the above did not 
goes well,
g++ alway add -lstdc++ and this caused multiple definition error.

So I first build them with without -lstdc++_s and  then eleteted *.dll and oct 
files.
And 
make -i &> make.log
awk '{if($1=="g\+\+") print $0}' make.log > tmp.text
to get 

g++ -shared-libgcc -shared -Wl,--export-all-symbols -Wl,--enable-auto-import

-lqrupdate -larpack

-lgfortran.dll -lgdi32 -lws2_32 -luser32 -lkernel32

-lgfortran.dll
-lgfortranbegin -lgfortran -lmingw32 -lmoldname -lmingwex -lmsvcrt -luser32 
-lkernel32
-ladvapi32 -lshell32
  :

I replace all 'g++' by 'gcc' and add  -lstdc++_s -lsupc++ at the last of linker 
flag by a text editor.

And then I used the modified link commands and built dll files and oct files. 

Size of oct flies were reduced by about 300 kbytes.

Finally I have tested make check.

The result

  c:\usr\Tatsu\mingwhome\octaves\octave-3.2.2\src\data.cc  PASS  506/509  FAIL 3
  test_string.m .......................................... PASS   78/79   FAIL 1

Summary:

  PASS   5736
  FAIL      4

is the same as the following without shared libstdc++

http://www.nabble.com/Re:-Octave-Version-3.2.2-Released-p24652801.html

However my way was too tricky, I think. 

Does anyone tried to build  octave by GCC-4.4.0-MinGW official with shared 
libstdc++ ?
