Which dll to use? Where to find the corresponding lib or dll.a?

[jwuttke]

I'd build the GSL shared library under MSys2:

pacman -S git cmake ninja gcc

git clone https://github.com/ampl/gsl.git
cd gsl
mkdir build
cd build
cmake -DBUILD_SHARED_LIBS:BOOL=ON -G "Ninja" ..
cmake --build .
ctest --output-on-failure

Everything goes fine, thank you very much for providing this excellent CMake support.

My questions now:

• In directory bin/, I find amplgsl.dll and msys-gsl.dll. What is the relation between these two? Do I need to link to both of them?

• Where are the corresponding lib or dll.a files? In the build main directory, I find libgsl.dll.a. Why yet another name?

• amplgsl.dll is a version of GSL's dynamic library that can be loaded from ampl (www.ampl.com), so it is a completely separate entity - you don't need it if you're not using AMPL
• can you check if now the static library is copied correctly?
