Also when running
$ ./2-build-debug.sh
I got a multiple of the these:
*** Warning: This system cannot link to static lib archive C:/msys64/home/20102/synfig.git/_debug/build/lib/libsynfig.la.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have.
*** Warning: linker path does not have real file for library -ldl.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libdl and none of the candidates passed a file format test
*** using a file magic. Last file checked: C:/msys64/mingw64/lib/libdl.a
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.
