Re: Building for Microsoft Windows using MSYS

Hello

I think that it is better to use pre-build libraries suggested Benjamin

I also suffer from this error generated the symbol  `_imp___ZNSt9exceptionD2Ev' 
g++ with
-D_GLIBCXX_DLL.  I have asked a  similar kind question for bad_alloc to the 
MinGW list but no reply
has been returned.

However, Benjamin might know to treat this issue.

BTW, in practical sense, it is better to use build libraries in octave-3.2.3 
binary package.

1. download and extract octave source
2. download patch

http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/admin/Windows/mingw32/octave/octave-3.2.3-4.patch?view=log
3. modify patch. version number  '3.2.3' should be replaced by '3.2.4'
4. apply patch with patch -p 1 < (patch file name) at the base directory of 
source trees
5. correct related source files manually if the some part of the patch fail
6. configure 
#example
cd (source directry)
# add PATH to use dll libraries, gnuplot, and gcc
export 
PATH=$PATH:/c/Programs/Octave/3.2.3_gcc4.4.0/bin:/c/Programs/Octave/3.2.3_gcc4.4.0/mingw32/bin

#FLAG setting
export CC='mingw32-gcc-4.4.0-dw2 -shared-libgcc'
export CXX='mingw32-g++-4.4.0-dw2 -shared-libgcc' 
export F77='mingw32-gfortran-4.4.0-dw2 gfortran -shared-libgcc'
#if you have installed gcc-4.4.0 you can use  
# export CC='gcc -shared-libgcc'
# instead the above
export CXXFLAGS='-D_GLIBCXX_DLL'
export LDFLAGS='-L/c/Programs/Octave/3.2.3_gcc4.4.0/lib'
export CPPFLAGS='-I/c/Programs/Octave/3.2.3_gcc4.4.0/include'
export CXXLIBS='-lstdc++_s'

./configure --prefix=(octave install directory path)

5. make 
6. make check
7. make install-strip
