Serguei Trouchelle used to provide Net::SSH2 on his ppm repo - built using 
MSVC++ and the Makefile provided in the win32 folder of the libssh2 source 
distro (I think). You could (as yet another alternative) take a look at the 
win32/Makefile.win32 and see if it offers any joy for you - I haven't tried 
it.

Anyway, under more extensive testing, there was a problem with Serguei's 
build, so he took it off the repo. (The actual problem was that the test 
script that ships with Net::SSH2 segfaulted after test 28 was run. The 
problem may since have been fixed faik.)

Yes, msys is *my* preferred option. (I use cygwin pretty much only for its 
'git' and 'svn' clients :-)

Here are some notes so far (and failures). On Solaris I had to build
shared libs to avoid this issue, but shared seems to be more problematic
though. Are you using gcc 4.5 and source versions of these packages
comparable to what I'm attempting to compile?

Here are some notes so far (and failures).  On Solaris I had to build
shared libs to avoid this issue, but shared seems to be more problematic
though.   Are you using gcc 4.5 and source versions of these packages
comparable to what I'm attempting to compile?


I've successfully used both 3.4.5 and 4.6.0  - 4.5 should be fine.

As regards my version of MSYS:

$ uname -a
MINGW32_NT-6.0 DESKTOP2 1.0.11(0.46/3/2) 2007-07-29 17:16 i686 unknown

The libssh2 failure in your attachment arises because libssh2.a has been 
statically built (probably because openssl is static, as you suspected) but 
then the process still goes looking for dynamic symbols (the '_imp__' 
prefix).


Usually there's a message about this in the build output (before the library 
gets built).


I don't have a dynamic build of openssl, though I think I've probably tried 
in the past. I'll give it another go later today and see if I can get 
anywhere. I'm fairly sure you'll need a dynamic openssl to build a dynamic 
libssh2. (The Strawberry build of openssl may be usable here if all else 
fails.)


If you decide that a static build of libssh2 will suffice, first run 'make 
distclean', then :


##
In the configure script, change:

case "$host" in
   *-mingw*)
   CFLAGS="$CFLAGS -DLIBSSH2_WIN32 -DWINSOCK_VERSION=0x0200"
   LIBS="$LIBS -lws2_32"
   ;;

to:

case "$host" in
   *-mingw*)
   CFLAGS="$CFLAGS -DWINSOCK_VERSION=0x0200"
   LIBS="$LIBS -lws2_32 -lgdi32"
   ;;

##

(That is, remove the '-DLIBSSH2_WIN32' and add the '-lgdi32'.)

Then (obviously) re-run ./configure with the static and shared args reversed 
, 'make', 'make check' and 'make install'.


Attached is the Net::SSH2 Makefile.PL that I then use to build the module 
against the static libssh2 library. It contains some hard coded paths (to 
msys headers and libraries) which may well be the same as on your machine 
 or might not. Modify those as needed and you should be right.


(It would, of course, be good to be able to also build a libssh2 *dll* - so 
I'll put a bit of effort into that as time permits. I expect that the reason 
I don't already have one somewhere is that I didn't succeed in building 
openssl shared libs.)


Cheers,
Rob

Compiled and installed fine with that change.  I used

./configure --disable-shared --enable-static CPPFLAGS="-I/usr/local/include -I/usr/local/ssl/include" 
LDFLAGS="-L/usr/local/lib -L/usr/local/ssl/lib"&&  make&&  make install

Here is where I am confused.  I thought I would stay in msys (at least 
for the purpose of getting SSH2.dll build at least)

(using: push @search_paths, '/local', '/local/ssl')
- see attached file msys1.txt (seems not only is the perl old and

It should work. (No problem for me on Strawberry 5.12.0.1.)
Looking at test1.txt it seems that there's a pre-existing build. Could you 
run 'dmake realclean', and then try again. (Post the 'dmake' results again 
if it still fails.)

Aaah ... found a Strawberry 5.10 installation and I get the same error as 
you reported.

Might need to use the same compiler both with Strawberry 5.10 and to build 
libssh2. (Doesn't seem to matter with 5.12.)

Can you alter your Strawberry path so that the mingw installation that built 
libssh2 is found *instead* of the mingw installation that ships with 
Strawberry ? That did the trick for me on Strawberry 5.10:

set PATH=C:\mingw\bin;%PATH%

(or whatever)

Rob

http://strawberryperl.com/release-notes/5.12.1.0.html mentions Net::SSH2 
does that have any bearing?

Let me update you first and then I will try what you suggest.  If you 
want to take this discussion off list for now we can do that and maybe  
I'll post back a guide to the list or something if somebody interested 
later.  If you want to keep it on list that's cool too.

dmake realclean tried to run "rm" command so I deleted/rextracted 
Netssh2 and copying back over the modified Makefile.PL.  I got the same 
results.  I then changed to use
push @search_paths, 'C:/msys/1.0/local', 'C:/msys/1.0/local/ssl', 
'C:/msys/1.0/mingw'

It looked like it was going to work then ld.exe crashed (got ld.exe 
stopped working dialog).  The box I am on at present is Windows 7 
64bit.  If you think thats a good chance of causing the problems which i 
suspect I'll stop for now until tomorrow when I get at my virtual XP 
install at work.

Just tried 5.12 portable.  Had to use the following pieces, but it worked
push @search_paths, 'C:/msys/1.0/local', 'C:/msys/1.0/local/ssl' , 
'C:/msys/1.0/mingw' (Makefile.PL)
set PATH=C:\msys\1.0\mingw\bin;%PATH% (strawberry shell)

Perhaps the extra search_paths element was needed due to additional 
differences in our msys installs

I will work more on 5.10 tomorrow.  I appreciate all the help :)

There have been problems with collect2 and mingw in the past. I would've 
thought they were fixed by the time 5.10 arrived, but perhaps not. (Otherwise I 
don't know what would be causing this.)

Windows XP was not affected; Vista (pre SP1) was ... not sure about Windows 7.

What's in C:/msys/1.0/mingw ? (My msys/1.0/mingw is empty.)

I need to specify 'C:/msys/1.0/local' and 'C:/msys/1.0/local/ssl' as that's 
where openssl and zlib are for me. 
However, some (most ?) people put their libraries into /mingw by making use of 
the --prefix argument. That way msys finds them by default. 

I guess therefore that, on your machine, there are some libraries in /mingw 
that are needed to build Net::SSH2 - whereas, on my machine, all of those 
libraries are in /usr/local. That should be the only difference.

Good that Strawberry are finally including Net::SSH2 in their distro.

While I think of it - I've found it necessary to apply this patch to SSH2.pm 
(version 0.33):

The premade msys that I used (linked in earlier emails) puts the mingw 
install inside the msys structure.  I tied  the install method described 
in the wiki and I think it created a c:\mingw dir and put msys inside of 
that.

I'm not sure about this. My msys doesn't seem to find all those mingw 
includes by default. With either install method I don't recall that a 
/usr/local exists until I started make install'ing stuff.   Is it 
possible that you have a mount?  I may try to install it according to 
the wiki again but it was so 'piece meal' that when I discovered a 
premade I used that instead.  If you have notes on creating a good msys 
install I'm interested in those too.

Thanks for the patch I will need it.

On checking, it looks like I could be mistaken about that.

I was basing that statement on the wiki at
http://www.mingw.org/wiki/MSYS :

#
To install 3rd party library and applications which uses the autotools build
system the following commands are often used.

./configure --prefix=/mingw
make
make install

Installing to "/usr/local" should be avoided, since the MinGW compiler won't
look there by default.
#

Maybe "/mingw" is not the same as "msys/1.0/mingw" ... perhaps it's
someplace else in the msys tree.

Anyway, I've always just let stuff go into /usr/local.
Besides, if one wants the stuff in /usr/local to be found by default one 
could just set the CPATH and LIBRARY_PATH environment variables 
appropriately:
export CPATH=/usr/local/include:/usr/local/ssl/include
export LIBRARY_PATH=/usr/local/lib:/usr/local/ssl/lib

If it's working ok (and it sounds like it is), I would happily leave it be.

I didn't see any issue until running dmake in the perl shell which 
didn't see all the canned mingw libs/includes.  Do you do anything extra 
to your strawberry shell env (outside of Makefile.PL) to make it aware 
of mingw/msys?

Yea, although I was able to get a msys setup going using the wiki as 
well, which works.

I've scrapped messing with 5.10 for now though because of the ld.exe 
crashing even on XP.  Here is my last issue:

perl -e "use Net::SSH2"
I get a dialog box -> This application has failed to start because 
libgcc_s_dw2-1.dll was not found.  Reinstalling the application may fix 
this problem.

I worked around it by adding C:\MinGW\bin to PATH for now.  Are doing 
anything extra to incorporate a static gcc lib into the SSH2.dll?

Forget about this question.  I checked back on my other box and it 
doesn't see
