I got the library and header pre compiled from some website, but I don't think they work with my compiler. Does anyone use the GMP with BCC. I have created a program but I get all of these linking errors such as. Error: Unresolved external '_mpf_init' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Error: Unresolved external '_mpf_set_si' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Error: Unresolved external '_mpf_ui_div' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Error: Unresolved external '_mpf_add' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Error: Unresolved external '_mpf_mul_ui' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Error: Unresolved external '_mpf_get_str' referenced from C:\A Bunch of My Folders\MAIN2.OBJ Help Me, Ben Pazolli Back to top Jonathan Benedicto Guest Posted: Sun Dec 31, 2006 5:47 am    Post subject: Re: The GNU Multiple Precision Arithmetic bpazolli wrote: Quote: Can some one help me to get The GNU Multiple Precision Arithmetic Library working with my Borland C++ Command Line Compiler 5.5.

If the BCC5.5 compiler includes implib, then run this command: implib GMP.lib <GMP dll name here>.dll Then, link that library into your code using a #pragma link GMP.lib in the source.

If you get a .lib file with the library, link your application against that lib file. Michel -- ---------------------------------------- Michel Leunen mailto: see my homepage.

I got the library and header pre compiled from some website, Exactly which "some website" did you get these from? GMP doesn't seem to ship with any libraries. The install process is supposed to compile the library for your machine. But it doesn't look like it is setup to use Borland compilers, so you would need to do it the hard way.

From that page: ----------------------------------------------------------------------------- The libgmp.a file I provided is still not a library for windows programs, but rather for a DOS extender environment. It needs to be linked with djgpp. I haven't tried other compilers for dos programs. I used RSXNTDJ version 1.6b to create a library libgmpw.a, which is useful for creating genuine windows programs. However, I haven't had time to include this file into the zipfile, or upload the patch that creates it. Sorry. So far, nobody (that I know of) has been able to get the libraries to work with MS Visual C++. Three have tried and failed and contacted me. I use the RSXNTDJ compiler to link my library into my programs. Soon (I hope) I will have access to MSVC++. I hope then to have time to get the library working with that package. Has anyone tried it with any other compilers, whether successfully or not? Please let me know! The highest version of GMP currently available is 3.0.1 (as of this writing). When they include FFT multiplications, I will put an updated library together. ----------------------------------------------------------------------------- So, this is a library, precompiled for use with the DJGPP compiler and linker. It doesn't work with Visual C++, and nobody has even been known to try it with any other compiler. You almost certainly need to compile the sources yourself, with the Borland compiler, and give up on using this precompiled library.

No I am not aware, I just started using c++. Maybe I was doing something too complicated. If any one can help me or give me a compiled library for C++ 5.5, I would appreciate it.

If you do not like that than you will have to do a conversion for borland compiler yourself.
