The error you're hitting is a standard linker issue—your build is trying to use functions from the METIS graph partitioning library, but the linker can't find the required library files to resolve symbols like metis_nodend_. Here are actionable fixes tailored to your MinGW64 environment:

Option 1: Install and Link METIS Properly (Recommended) #

METIS is a dependency for key HSL modules like MA57 and MC68. Let's get it set up correctly:

1. Install METIS via MSYS2 Package Manager
   Open your MinGW64 terminal and run this command to install precompiled METIS:

   pacman -S mingw-w64-x86_64-metis
   

   This will place the library and headers directly into your MinGW64 system paths.

2. Rebuild HSL with Detected METIS
   Clean your existing build artifacts and reconfigure to let the build system pick up METIS:

   make clean
   ./configure
   make
   

   The configure script should automatically detect METIS and update the link commands to include the -lmetis flag.

3. Quick Fix for the Current Link Command
   If you don't want to restart the full build, modify your existing link command to add -lmetis right after -lopenblas:

   gfortran -shared .libs/libcoinhsl-0.dll.def common/.libs/deps90.o common/.libs/deps.o common/.libs/dump.o mc19/.libs/mc19d.o ma27/.libs/ma27d.o ma28/.libs/ma28d.o ma57/.libs/ma57d.o hsl_ma77/.libs/hsl_ma77d.o hsl_ma77/C/.libs/hsl_ma77d_ciface.o hsl_ma86/.libs/hsl_ma86d.o hsl_ma86/C/.libs/hsl_ma86d_ciface.o hsl_mc68/C/.libs/hsl_mc68i_ciface.o hsl_ma97/.libs/hsl_ma97d.o hsl_ma97/C/.libs/hsl_ma97d_ciface.o loadmetis/.libs/loadmetis.o -L/mingw64/lib/ -lopenblas -lmetis -lpthread -lgfortran -O2 -Wl,-rpath -Wl,/mingw64/lib -o .libs/libcoinhsl-0.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libcoinhsl.dll.a
   

   Run this modified command, and the linker should resolve the missing symbols.

Option 2: Disable METIS Dependency (If You Don't Need It) #

If you don't require METIS-based graph partitioning features in HSL, you can disable this dependency entirely:

1. Reconfigure with METIS Disabled

   make clean
   ./configure --without-metis
   make
   

   This skips compiling METIS-dependent code, so the linker won't look for those symbols anymore.

Why This Error Occurs #

Your HSL build was configured to use METIS (either by default, because METIS headers were present during initial configure), but the final link command didn't include the -lmetis flag to link against the actual METIS library. The linker needs this flag to find and connect the missing function definitions.
