g++: error unrecognized command-line option -municode using Cygwin

I am trying to build GetDP (finite-element sofware) from source using the 64-bit GNU compilers in Cygwin, namely gcc.exe, g++.exe and gfortran.exe, with their toolchain x86_64-pc-cygwin. I have the same error while linking the executable getdp.exe (in my case raised by the g++ compiler):

g++: error: unrecognized command-line option ‘-municode’

How can I solve the issue? Are there some packages that can be installed within Cygwin to enable the -municode command in the toolchain of the compilers? I have very little experience with C/C++ programming and compilation. Any help is really appreciated.

Strictly related to this issue.

Solution

  • The problem was not in Cygwin compiler toolchains, but in the CMakeList.txt file of the software I was trying to compile (GetDP). Now the issue is fixed and the executable can be built without any errors using both gcc and mingw-x64 within Cygwin.
