Description
Trying to compile libmodbus on a Windows 10 machine. I have the latest MSYS2 installed. I cloned the sources from git://github.com/stephane/libmodbus
In a MSYS2 command line I run the autogen.sh and then the configure scripts, but it fails. Following the result of the two commands. Any help appreciated.
Expected behaviour
libmodbus to compile
Actual behaviour
./configure errors
Steps to reproduce the behavior (commands or source code)

on a Win10-64bit computer within MSYS2_64bit i've installed with pacman the following packages
pacman -S autoconf automake-wrapper libtool make mingw-w64-i686-gcc
then i've compiled with 32bit gcc the 32bit dll of libmodbus .
with the mingw-w64-x86_64-gcc package it's also possible to compile a 64bit dll of libmodbus .
How do I choose gcc 32 rather than gcc 64? Also, I want to use the dll in a C program, I think I would need a .lib and the headers, can you tell me how to compile for that?
in MSYS2_64bit run mingw32.exe , then within the MINGW32-terminal the "gcc"-command is 32bit .
I'm new to this type of programming, I have a background in embedded programming. You're saying that I can use only the dll and the headers files and only call the functions in my code? How do I tell to the linker to use the dll? I'm planning to compile with gcc in code::blocks.
i'm doing dynamic calls to the libmodbus dll from LabVIEW . it's similar to calling a dll from python with ctypes or CFFI .
doing such indirect calls to a C library like libmodbus from C is not needed and probably more complicated than just using the C library libmodbus directly form a C program . i hope that other users here could help you with how to use libmodbus from C .
on a Win10-64bit computer within MSYS2_64bit i've installed with pacman the following packages
pacman -S autoconf automake-wrapper libtool make mingw-w64-i686-gcc
Hey, you saved my day! I missed to install autoconf and automake-wrapper and got strange error messages.
How do I choose gcc 32 rather than gcc 64? Also, I want to use the dll in a C program, I think I would need a .lib and the headers, can you tell me how to compile for that?
I installed MSY2 in 64 bit version, and in Win10 I got multiple icons/quicklinks with each one stands for one compiler/environment:
- magenta/violet for general MSYS2 shell (perhaps with cygwin?)
- grey for MINGW32
- blue for MING64
- brown for UCRT64 (successor for MSVCRT)
- orange for CLANG64
when I need to write 32 bit stuff with pure make, I just open the grey icon's shell, g++ is then:
$ which g++
/mingw32/bin/g++
while the blue icon creates a bash with:
$ which g++
/mingw64/bin/g++
(Except when working from Codelite, which needs some of its own tools in path and can scan and offer all the MSYS2 compiler frontends, there I just start Codelite and select the compiler from the project properties)
HTH, Mo
Code::Blocks and CodeLite are quite related, so my experience of better not calling codelite from within MSYS2 shell could also apply to Code::Blocks? I had:
- mkdir /p will only work if codelite is in $PATH, since this tool is there
- UnitTest++ seems to only work if codelite was invoked from start menu or CMD shell, never found the reason
- CodeCompletion ... same, never found the root cause
On DLL ... why do you want use it via DLL? The libmodbus isn't that large, to save storage by sharing same DLL with different modbus tools. You could link it statically. The LGPL 2.1 makes no difference here.
Sorry for the necro
I have the same issue I installed all the packages listed by @dreamflow, tried with the 32bit mingw and the 64bit. I still get the same error as @effemmeffe
@BobinInk : for my last successful libmodbus.dll 64bit compilation , i've installed into MSYS2_64bit the needed packages via
pacman -S autoconf automake-wrapper libtool make mingw-w64-i686-gcc mingw-w64-x86_64-gcc mingw-w64-ucrt-x86_64-gcc
in MSYS2_64bit i've started ucrt64.exe and within this
ucrt64-terminal i've performed the compilation steps on the
downloaded and extracted libmodbus-source-github-master-branch-zip via
./autogen.sh
./configure
make
that resulted in a functioning 64bit libmodbus.dll .

OK！ Download all code ，and checkout v3.1.10，build error But just download releases tag v3.1.10,build correctly！ https://github.com/stephane/libmodbus/releases
