Comments regarding also the other (remaining) issues: Yes, the 2.7.0 documentation failed to load from here (Germany), now again.
I did not use "sudo" - it did not recognize this command ("not found") - what is it? For administrators? (One of my machines is administrated by a super user.) I just used "make install". I tried also gcc mytest.c -o mytest -lmpir -IC:/MPIR/mpir-2.7.0/ -LC:/MPIR/mpir-2.7.0 but still no improvement ("cannot find -lmpir"). In my top MPIR directory MPIR/mpir-2.7.0, there is an "mpir.h" file, a "libmpir.la" file, and in the .lib subdirectory various similarly named files, in particular, again "libmpir.la", then "libmpir.lai", "libmpir.dll.a" and more - but nowhere a file called "libmpir.a" . Is this the system as it should be? I did, in any case, perform "make check" and "make install" without any errors... how do I check if the installation was successful? Thank you.
