Issues & questions building Octave-3.4.2 MinGW

[Philip Nienhuis]

Tatsuro,

Using the development files and the clear instructions you uploaded to
  http://www.tatsuromatsuoka.com/octave/Eng/Win/
I was able to build Octave-3.4.2 MinGW, too.

Thank you very much for making this possible!

A few questions & remarks, perhaps some can be included in 
Readme_octave-3.4.2.txt :

GIT
===
git is needed for ./autogen.sh  (in turn needed for jwe's patch for tmpfile)
Easily solved by downloading the msysgit installer
   http://code.google.com/p/msysgit/
install/unpack it somewhere, let it compile its stuff, and after that 
copying the newly created git files (7 pieces IIRC) to msys/bin (the 
msysgit directory can be erased, it's no more needed).
For mercurial => tortoisehg
cygwin can be avoided then.

As to gnulib, snapshots can be downloaded using the trick outlined here:

Next step, configure complained about a few things:

1. Missing Freetype library.
Is it included in your OctaveLibs.zip?
I built freetype-2.4.5 myself, put libfreetype-6.dll in OctaveLibs/bin & 
libfreetype.dll.a, libfreetype.la and libfreetype.lai in OctaveLibs/lib.
But still configure can't find Freetype :-(


2. In configure.log I get this:
 :

<lots more of similar errors>
 :
(watch out for line wrap!)

Comparing Enumerations.h in MinGW and on Linux I can't spot what's wrong 
here (but admittedly my C++ skills are meager).


3. Here and there, while configure does (e.g., here):
 :
checking for mkdirat... mv: cannot move `conftest.er1' to 
`conftest.err': Permission denied no
 :

...I get a Windows systray message:
   "conftest.exe: Corrupt file"
and next boot it wants to run chkdsk.
Do you get such error messages too?

configure.log entry on mkdirat:

 :

| #define mkdirat innocuous_mkdirat
|
 :
(watch out, line wrap)


Next step, running make, I get other little issues, easily solved:

4. Need to #include unistd.h twice
(already outlined in your instructions, in my case only needed  for 
src/oct-hist.cc)

5. "unlink is not a member of gnulib"
Solved by Ole:
http://octave.1599824.n4.nabble.com/MinGW-compile-problems-tc2251930.html#a2252205

After that the build was successful. PASS 7016, FAIL 3.

I hope you can hint me about the freetype library.


Thanks,

Philip
