Build libmodbus, linker error

[Wagner, Martin]

Hi,

I'm trying to build libmodbus (https://libmodbus.org/), but run into a linker 
error:

"/usr/bin/ld: cannot find -lwsock32"

libmodbus is a c library and uses autotools, so nothing special.

I've tried the steps from the tutorial, also the ones with additional configure 
flags, but I always get the same error. Did I miss something?

Thank you for your help!

Regards,
Martin

mxe build command:
$ make qt6-qtbase boost MXE_TARGETS='x86_64-w64-mingw32.shared'

package build command (as in tutorial for autotools, except for "shared"):
$ export PATH=/opt/mxe/usr/bin:$PATH
$ ./autogen.sh
$ ./configure --host=i686-w64-mingw32.shared
$ make
