MinGW for Harbour Development

[David Allen]

Hello Harbour,

Could someone explain this to me or at least which is best for Harbour development.  I have no idea what all this is...posix, dwarf, etc. .

MinGW-W64 GCC-7.3.0

• x86_64-posix-sjlj
• x86_64-posix-seh
• x86_64-win32-sjlj
• x86_64-win32-seh
• i686-posix-sjlj
• i686-posix-dwarf
• i686-win32-sjlj
• i686-win32-dwarf

Thank you.

Respectfully,

David

[Eric Lendvai]

Thanks David for asking that question !

In my article https://harbour.wiki/index.asp?page=PublicArticles&mode=show&id=190129210053&sig=7790451073#section_4723219445

I decided to use i686-win32-dwarf but was still not certain why.

[David Allen]

Hello Harbour community,

I did some research and found this information scattered all over.  Here is what I found.  Hopefully it will help someone else..

What are x86_64 and i686?

i686 is a 32-bit instruction set (part of the x86 family line), while x86_64 is a 64-bit instruction set.  An operating system will either be 32 bit or 54 bit.

What are posix and win32?

This setting determines whether or not your code will take advantage of multithreading functionality. Posix supports multithreading while Win32 does not.

Posix and Win32 are Operating System Standards.  Android, Linux, and Unix are mostly compliant with this standard.  However, MinGW, a fork of Cygwin, provides a less POSIX-compliant development environment and supports compatible C-programmed applications via Msvcrt, Microsoft's old Visual C runtime library.  

What is a thread?

A thread is a sequence of such instructions within a program that can be executed independently of other code.  

Exception Handling

An exception is an error. This is used by the programming language to report error conditions. There are 3 types to be aware of when using MinGW

• Seh
• Windows uses its own exception handling mechanism known as Structured Exception Handling (SEH)

• Dwarf
• Must be used for 32 bit Windows Applications.

• Sjlj
• Must be used for 64 bit Windows Applications.

So, i686-win32-dwarf, as Eric points out is the best usage of MinGW targeting Windows 32 bit.

Please see his article for more information...

Respectfully,

David

I use what was recommended on Harbour 3.4, since old mingw.

Latest use:

x86_64-7.3.0-release-posix-sjlj-rt_v5-rev0

x86_64-8.1.0-release-posix-sjlj-rt_v6-rev0

I allways use multithread.

Download is about 50MB.

Developer machine need to be 64 bits, but can create win32 or win64 applications.

https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/7.3.0/

Note:

To use 8.1, may be you need to add this on hbc file:

{mingw}CFLAGS=-Wno-implicit-fallthrough -Wno-cast-function-type -Wno-misleading-indentation

Hi David,

currently i'm using MSYS2 toolchains.

Please note that they come with sjlj error exception handler for i686 and seh for x86_64.

About the differences between the EEHs (from Qt wiki):

SJLJ (setjmp/longjmp):
 available for 32 bit and 64 bit
 not "zero-cost": even if an exception isn't thrown, it incurs a minor performance penalty (~15% in exception heavy code) but sometimes the penalty can be more significant

DWARF (DW2, dwarf-2)
 available for 32 bit only
 no permanent runtime overhead
 needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g. Windows system DLLs.

SEH (zero overhead exception)
 available for 64-bit GCC since 4.8 version.

An important thing to take in count: if you plan to link QT downloading the pre-built libraries, these are only 32bit and dwarf-2 compliant.
Thus, for 32bit install you need to build Harbour with the same dwarf-2 toolchain ( you find it here: https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/7.3.0/threads-posix/dwarf/i686-7.3.0-release-posix-dwarf-rt_v5-rev0.7z/download ) or, for 64bit install, you need to build Qt from scratch (you find how here: https://wohlsoft.ru/pgewiki/Building_Qt_on_MinGW-w64 )

Personally, I prefer MYS2 toolchains because they are updated ( 9.2 is the current version instead of 7.3 ), resulting in more accurate checking in compile and enhanced executables speed.
If needed, I could make available Harbour binaries derived from MinGW 9.2 for both 32 and 64 bit.

Best regards.

Yes thank if you made aivailable Harbour binaries derived from MinGW 9.2 for both 32 and 64 bit.  amd fpr hbqt 

if possible using niglty from Francesco

imo msys2 is the better choice for harbour

Mi spego in italiano Ti sarei davvero grato se aggiorni i binari di harbour per 32 e 64 bit in una versione compatibile con hbqt e magari aggiornando harbour Nigltly  gestita da francesco suy https://sourceforge.net/projects/harbour-project/files/binaries-windows/nightly/harbour-nightly-win.exe/download

Hi Massimo,

what I can do is to publish on my site Harbour binaries built for 32bit (sjlj flavour) and 64bit (seh flavour).
As I said, AFAIK, none of both is compatible with Qt binaries currently downloadable (because are 32bit dwarf-2 flavour).
Thus, to link Qt with Harbour libraries that I could build, you should compile Qt from scratch using MSYS2 MinGW compiler.

I did that and AFAIR, apart the long time it toke to build, I noticed some incompatibility due to the Qt sources, no such updated to build with newer versions of MinGW.

In addition, I can't use the web space of nightly builds of Francesco.

Perhaps, Mel in his whosaway.com repository is already planning to release a 9.2 version of binaries. Currently he's publishing 8.1 version and shouldn't have problems to update.

Best regards.

Hi Maurizio:

   I cannot find a link to a MinGW 9.2 version for download.

   If you provide a link, then I will try to update whosaway.com MinGW to 9.2

Hi Mel,

as I said I'm using MSYS2 for download and update the toolchains and the libraries needed to build my Harbour apps.
You can simply install MSYS2 and update via pacman the packages to obtain the 9.2 gcc compiler in both 32 and 64bit flavour.
A good guide is at: https://solarianprogrammer.com/2019/11/05/install-gcc-windows/

Hi Grigory:

   I have downloaded, extracted to c:\MinGW920, and will test later today hopefully.

Thank you !

Hi Maurizio:

  I will test your usage of MinGw 9.2.0 under msys2  after I try out Grigory's offering.

Hi Grigory:

   I tried to create a 32-bit build for Harbour 3.2 from your MinGW 9.2.0 download link.

   Here is my log of the build which shows an almost immediate crash when trying to compile png.o from png .c

   I don't know what change I should make to get this very first compilation to work properly ?

Thanks for any iguidance you may wish to provide:

Hi Mel,

> I tried to create a 32-bit build for Harbour 3.2 

it is expected behavior because the author of this distro wrote:

My MinGW distribution ("distro") is x64-native

Please try the above MinGW build with Harbour 3.4 ;-)

Thanks Maurizio for all the info as well. I guess I should update the Article I create about installing Harbour to add all this info, from you and others.

I am just first finishing the FastCGI article ... longer than I planned. 

Should have some time after that to contact you, Thanks !!!

Hum, thus the issue could be due to the MinGW distro.
What I can assure is that MinGW based on MSYS2 builds fine Harbour, both for 32bit and 64bit.

Perhaps the MSYS2 path I suggested is the better choice.

Anyway, just for curiosity, why you're including in the system path also the library and the include folders?
AFAIK, only binary files are searched in path.

Also C:\mingw920\x86_64-w64-mingw32; should be needless, but I don't know the content of the distro suggested by Grigory.

Best regards and good golfing.

Hi All:

   FYI:  I have posted on www.whosaway.com Harbour 3.2 64-bit Version (1912031042) built under MinGW 9.2.0 This MinGW920 version is standalone (i.e., it does not use msys64 for its creation)

   I thank Grigory Filatov for his repo of MinGW 9.2.0 and Mauricio la Cecilia for his efforts to help me overcome my compile errors. This MinGW version does not allow me to create a 32-bit version (or at least, I don't know how to accomplish this after two days of 'head beating on desk')

   Hope some of you can download this package and test it for speed and correctness.

-Mel Smith
