Hello, I have been able to compile 1.1.0 with no issues using just about all versions of VStudio .NET2003/2005/2008/2010. So, all good there. However, the compilation process using Visual studio 6 has not been smooth and still fails. Here is the environment I am using: - CL.exe - Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86 Copyright (C) Microsoft Corp 1984-1998. All rights reserved. - Windows Server 2003 SP1 SDK - My desktop is running Windows 8 Version 6.3 (Build 9600) I have been modifying 'a bit' a few of the source files and makefile to make it work. Simple things as compiler not recognizing certain macros such the declaration of the 'long long' variable using LL, which I had to switch to i64 (see 2 lines below) //static const int64_t kBottom25Bits = 0x1ffffffLL; // original line static const int64_t kBottom25Bits = 0x1ffffffi64; // it now compiles using Visual Studio 6 compiler I was able to compile the core programs but now getting lots of errors while compiling the 'test programs', so I wanted to post this message to see if this is due to the environment I am using and/or user error or if there is a real issue somewhere. Most of the issues while compiling the test programs are linked to missing data types while using the #define statements in the source code - which there are hundreds of them. Since I just registered to gain access to this group and this is my first post, I'll wait to see if someone wants additional (specific details) about my project. I can then send make file and specific errors during compilation. Thank you very much for anyone replying to my email.
