Which version?

from libmodbus.

I'm on windows XP pro SP3; using cygwin 2.738
I've download "stephane-libmodbus-v3.0.0-0-g00cb49e.zip"

after the finish of configure with "no" error (nothing is written on the screen)
the execution of make command tell me :

make all-recursive

I can't copy all the screen to paste here so the commands are truncated. I'm sorry this is my first use of cygwin.
thank you

from libmodbus.

OK, I've merged some fixes for Windows for the v3.0.1
Can you test again with https://github.com/stephane/libmodbus/zipball/v3.0.1 ?

from libmodbus.

I have the same warning but the make command give me another thing with this version :

It's useless to post so many lines for just this error, you just have an issue with xmlto or your asciidoc installation.
The libmodbus is designed to be compiled under mingw not cygwin.

Your initial problem is fixed (winsock2.h error) so the but must be closed.
Feel free to submit patch for Cygwin, but please don't submit bug report for this environment, I won't take time to support it.

from libmodbus.

thank you for your response .
I'm sorry to flooded you but since i'm not the original creator of the library i can't know what thing can be important to have to debug.
and for cygwin i never saw that the library was designed only for mingw . with the previous release cygwin and mingw had the same results and i thought it was the same with this version. It can be good for beginners to write it in the readme.rst and to avoid you wasting time for nothing.
I will use mingw : it appears to be OK.
