Hello MPIR Team, I'm not sure if you really do support using this e-mail address, but the Contact Us portion of your website led me to this address. I am trying to build MPIR on my personal computer, mostly for recreational use (Project Euler and the like). I used Rick Reagan's instructions at http://www.exploringbinary.com/how-to-install-and-run-gmp-on-windows-using-mpir/ since they seem to be referenced by many people across the web, but I'm not sure how applicable they are to my machine and setup. I am using a Lenovo T530 machine with an Intel Core i5-3360M 2.80GHz processor. My OS is Windows 7 Home Premium 64-bit. I am using the Visual Studio Professional 64-bit programming environment. I am trying to install mpir-2.6.0, and I used vsyasm-1.2.0-win64 as the assembler. I followed Rick's instructions for installing the C++ wrapper (mpirxx) in addition to the C part. I can have a project build when I #include <mpirxx.h>, but when I try to use the integer type, I get several linker errors that seem to indicate that there are several MPIR methods that the compiler is missing definitions for. To follow is the code and the error list. I am hoping that I have just missed a file that needed to be included in the VS directories, and really hope that none of this is occurring because I tried to build things meant for VS2010 in VS2012. I have also become very sorry I am using Windows and not Linux ;) . This is my first time trying to install an external library, so it is highly possible that I made some other mistakes somewhere. Thank you for your time, I appreciate any help/pointers. Sincerely, Terence The errors: error LNK2001: unresolved external symbol __gmpz_set_si error LNK2001: unresolved external symbol __gmpz_clear error LNK2001: unresolved external symbol __gmpz_init_set_si error LNK2001: unresolved external symbol __gmpz_get_str mpirxx.lib(ompz.obj) error LNK2001: unresolved external symbol __gmp_asprintf_memory mpirxx.lib(osfuns.obj) error LNK2001: unresolved external symbol __gmp_asprintf_reps mpirxx.lib(osfuns.obj) error LNK2001: unresolved external symbol __gmp_asprintf_final mpirxx.lib(osdoprnti.obj) error LNK2001: unresolved external symbol __gmp_doprint_integer mpirxx.lib(osdoprnti.obj) error LNK2001: unresolved external symbol __gmp_allocate_func mpirxx.lib(osdoprnti.obj) error LNK2001: unresolved external symbol __gmp_free_func mpirxx.lib(osdoprnti.obj) According to VS: The first 3 are related to project_euler_problem_16.o (my file).
