Hi Dear Gretl Guys,
Sorry to bother you guys but I've been struggling for several days on this.
I am trying to write a C++ program on Windows that I want to use some gretl functions,
like nadarwat(). But I just cannot compile with libgretl. I can't find libgretl.h, let
alone its .lib file even though I did see libgretl.dll under my "C:\Program Files
(x86)\gretl" directory.
This is what I did. I followed instruction from http://gretl.sourceforge.net/win32/ and
installed. gretl-1.9.7.exe, but I did NOT find any header file that I can compile with. I
then download gretl with source code gretl-1.9.7.tar.bz2 but I am not sure I know how to
build it on Windows(I am only familiar with Visual Studio IDE).
From my understanding of gretl on Windows, once I run gretl-1.9.7.exe, it should install
gretl GUI and libgretl automatically, right? libgretl is for people who want to write
their own C++ program to compile and link with gretl, right? But where is libgretl.h and
possibly libgretl.lib after running gretl-1.9.7.exe? Are they supposed to be simple to
find?
Really need your guys help. Thanks a lot in advance.

It's not exactly like that: the exe installer just install the complied
version of the library, the one which the application needs to execute the
libgretl functions. In order to build a C application that uses libgretl,
you need to download the source. You may find this page useful:

Got it Jack, so I will follow your instruction to go to that url and do it the hard way
and see whether libgretl.h and libgretl.lib files can be generated. It's a little bit
inconvinent because I am not so familiar with compiling with Makefile, but thank you so
much!

The libgretl headers (including libgretl.h) don't have to be
generated: they're present in the source package.
The supplied gretl Makefile for Windows does not call for
generation of a .lib file, but it creates libgretl.dll,
libgretl.def, and the import library libgretl.a. You may want
to take a look at this discussion:

Actually it seems to be simpler than that. From
http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs :

MSVC cannot use the MinGW library, but since you have already
the DEF file you may easily produce one by the Microsoft LIB

Hi Allin,
I find libgretl.h and libgretl.dll in gretl source, so my goal is to compile this source
code to generate libgretl.lib to be linked by my C++ app in MSVS2010. Thanks a lot for
your links. Looks like I need to first compile gretl source with MinGW, then use Microsoft
LIB tool to convert the generated .a file into .lib file so it can be used in MSVS.
I'll try to follow instructions outlined by Jack, you and that from those links. Thank
you guys very much!

That's the route if you're building gretl with mingw, but it ought
to be possible to build with the Microsoft C compiler (in which case
you'd presumably get a .lib import library by default, along with
the libgretl DLL).
Nobody in the gretl team has tried that, but I suppose it's just a
matter of creating the right nmake file or "project" file; the
mingw-oriented Makefile should provide a basis.

Thank you Allin. I will try with Microsoft C compiler first to see if I have any luck
Sad to hear "Nobody in the gretl team has tried that". I know you guys create
great useful software, but meantime, please think more for MSVS user. I assume there are
lots of developer like me, who have used VS IDE for years but don't dare to try gcc or
alike since those compilers are not very user friendly(I am so afraid of writting makefile
mannually, on the contrary, in VS, it's just a matter of mouse click...).
Thank you for the advice so much, Allin.

I hear you, but try thinking about it from the other side: I don't
own a copy of the Microsoft C compiler, which is an expensive
proprietary product. If someone donated a copy to me I might be
tempted to produce an nmake file or project file for libgretl. I
have Windows 7 on my university-supplied computer; I don't often
boot into Windows (the computer also has a Linux partition) because
I don't like the operating system, but I might do so in order to
help other people -- if I didn't have to pay big money for the
proprietary software I'd need.

are not very user friendly(I am so afraid of writting makefile
mannually, on the contrary, in VS, it's just a matter of mouse
click...).
The gretl package contains a mingw-style Makefile ready to run. But
if it's just a matter of mouse-click in VS, please submit a VS
project file and we'll be happy to put it on the gretl website. I
don't mean to be snarky: if building gretl on Windows via native MS
methods is ever to be easy, we need Windows users who are also
open-source enthusiasts users to contribute their expertise.

Hi Allin,
"I don't own a copy of the Microsoft C compiler, which is an expensive
proprietary product".
I hear you Allin, but you're probably wrong on this: Even I always use VS professional
or above edition which does require payment, I believe MS does offer VS Express edition
which is FREE. Here is a link I just find by google search:
http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual...
And I believe VS Express edition should be enough to compile libgretl. VS professional and
above edition does offer some other capabilities, but that's mainly for .Net
capability. For unmanaged C++(the ansi C++), it's basically the same for all VS
version. (I have no intention to do advertisement for MS. MS are creating sometimes
unnecessarily complicated stuff but they occasionally also make some good stuff, like this
user friendly IDE, especially when it's free).
I'll try to compile libgretl with VS 2010 on Win 7 based on you guys instruction. If
it works, I'll be glad to submit the VS project file I used if it can be of any help.
Meanwhile, you guys are so welcomed to download free VS Express and try compile by the
original source code developer which maybe much easier and correct(if you guys can write
complicated makefile, figuring out how to config VS project file for compiling libgretl
should be a piece of cake).
By the way, I myself am very interested to be an open-source enthusiast. Talk to you guys
later. Thank you so much.

I don't mean to get overly ideological on this, but surely it must be free

Although I very much welcome the interest of experience Win programmers in

Hi Jack,
Took a while to understand the difference between free beer and free speech. Ok, looks
like I have to do VS compilation of libgretl all by myself no matter how free VS Express
is. Once it compiles, I'll let you guys know. Thx a lot.

slightly hijacking this thread: I find it very interesting that recently
there seems to be an increasing number of messages on the list that deal
with libgretl, meaning that it is used on the C level AFAICT.
Is there a (positive) structural break there?

Well, strictly speaking you could in theory use libgretl from C++, C# or
even Python (see http://ideas.repec.org/h/ehu/ehucha/01-14.html)
Is there a (positive) structural break there?
So it would seem. Fingers crossed.
