msys.bat should be located in the 1.0 folder in the msys folder in the MinGW folder.

Oh yeah, how can msys know about which directories I store various libraries in?
Is there a guideline, sticky post on this?
Thanks
Jack

According to the instruction link, MSYS-Installer will ask for the installation directory of MinGW.
After installation, type "export" in your console to see which directory MSYS refers to.

It's referring to C:\mingw\msys\1.0\bin;

I start msys on the command prompt, my system is win7 x64, the path has got 32-bit mingw at the very front.
the msys is pointing to it by checking with mount

1checking whether -lc should be explicitly linked in... yes
2checking dynamic linker characteristics... Win32 ld.exe
3checking how to hardcode library paths into programs... immediate
4checking whether stripping libraries is possible... yes
5checking if libtool supports shared libraries... yes
6checking whether to build shared libraries... yes
7checking whether to build static libraries... yes
8checking for GCC -fvisibility=hidden option... yes
9checking for sdl-config... no
10checking for sdl2-config... no
11checking for SDL - version >= 1.2.0... no
12*** The sdl-config script installed by SDL could not be found
13*** If SDL was installed in PREFIX, make sure PREFIX/bin is in
14*** your path, or set the SDL_CONFIG environment variable to the
15*** full path to sdl-config.
16configure: error: *** SDL version 1.2.0 not found!

I've set a SDL_CONFIG variable outside of msys (win7 command prompt) and it points to the sdl-config file on my hard drive
I separately put the sdl (mingw) file in another folder.
Thanks
Jack

How strange is when I export my sdl-mingw/bin with sdl-config and the version no is 1.2.15, the error still appears.
Thanks
Jack

Any help would be greatly appreciated!

Why does the configure program stop working but actually I have sdl-mingw win32 development version 1.2.15?
It's obviously above 1.2?
I have set the path for the sdl-config file correctly

I've reinstalled everything, then installed SDL, then set the variable for the SDL libs, go to msys, then
typed ./autogen.sh followed by ./configure followed by make, I am getting the above errors

There must be the following 'define' somewhere in cross.h

1#define alloca _alloca

You may also manually replace alloca with _alloca in dos_files.cpp.

Hello ykhwong,
No neither alloca or _alloca was defined.
I just want to know exactly what steps you are taking to build your dosbox?
Let me know
Thanks
Jack

I confirm that alloca is defined in cross.h. You obtained 20130725 source uploaded on my website?

Downloading clean, vanilla one is recommended because its binary is more stable than svn-daum and it requires very few libraries.
With the clean svn build source, you may easily follow this wiki link: http://www.dosbox.com/wiki/BuildingDOSBox

I am not using MinGW/MSYS which includes a port of the gnu compiler collection and I have no step-by-step instruction right now.
I will summarize what I am doing on Linux that also contains gcc.
My build requires sdl, physfs, zlib, libpng, fluidsynth, libflac, libogg, libvorbis, libpcap, freetype, sdl_net, sdl_sound, and libtbb. Install them in this order.
Get the latest mercurial of sdl_sound which must be copmiled after installing libflac, libogg, and libvorbis. (libogg is also required by libvorbis)
After setting up all of the above dependencies, you can finally build my dosbox without problem. This applies both to gcc and visual c++.

Before building svn-daum dosbox, type these two lines:

1export LIBS='-ltbb -lFLAC'
2export CXX='/usr/bin/g++ -std=c++11'

I didn't add them to configugre.ac yet AFAIK.

Thanks ykhwong, I'll try to compile it, as I'd like to write an ansi patch to your build...

What is libtbb used for? To my understanding, it is a debian .deb file.
Or there is another libtbb existing?
Do I need it?
Thanks
Jack

The libtbb is used for speeding up processing xBRZ scaler on modern multi-core CPUs.

okay, ykhwong, many thanks to you...

When building libFLAC
Error 89 error MSB6006: "cmd.exe" exited with code 9009. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets 151 6 libFLAC_static

I am getting an error, did you ever encounter this before?

When building sdl sound
BTW, do I need SMPEG, mpglib?

Error 1 error C1083: Cannot open source file: '..\decoders\smpeg.c': No such file or directory E:\Jacky\Downloads\dosbox\mercurial\SDL_sound\VisualC\c1 sdl_sound_dll
Error 2 error C1083: Cannot open include file: 'vorbis/codec.h': No such file or directory e:\jacky\downloads\dosbox\mercurial\sdl_sound\decoders\ogg.c 51 1 sdl_sound_dll
Error 3 error C1083: Cannot open source file: '..\decoders\mpglib.c': No such file or directory E:\Jacky\Downloads\dosbox\mercurial\SDL_sound\VisualC\c1 sdl_sound_dll

Thanks
Jack

You don't need SDL_sound. It's good for cue files with mp3 or ogg files, I think. If you think you need it grab a precompiled one.
Or build everything needed which you obviously haven't (ogg/vorbis)
