thanks brian and aleksey....well i installed the latest beta of visual studio 2005 instead of my mvc 6.0. It did get rid of the block scoping issues and many other compiling issues i was facing. I had to replace the apply_if with eval_if everywhere. could understand the exact technicalities of that, but read it from some post on the forum and just followed it..... now, i got different issues though....everything compiles perfect but i get like a million linking issues.......... the details are as follows: HelloWorld_GameApp.obj :error LNK2019: unresolved external symbol _memcpy_s

specific which i will have to dig into..... well, i am trying to make luabind and boost work with someone elses code.....so i do not completely understand it myself.... just trying to register a few classes from there thru a hello world app and trying to work my way from luabind from there..... any assitance over here will be appreciated.... also, just to verify, for linking what all .libs need to be listed in the project options... i have lua.lib, lua_debug.lib... i have the paths for luabind and boost set up as per the documentations...is there anything else that needs to be done to get the environment correct...just wondering if i am missing out on any .libs to be listed in the project settings???? thanks and regards, rohit ---------------------- you wrote: Brian Braatz] "

This shows me you are using VC6. While you "can" do this, you are asking for more pain than anyone should be forced to have. (it is not very compliant and has lots of template quirks. AND you get pages (and pages and pages and pages) of template warnings on valid code (making debugging compile time issues much more difficult) My *strong* suggestion to you is you install at least Visual Studio .net 2003 which comes with the vc++ 7.1 compiler. If you cannot purchase this product, the command line compiler is available for free download from: http://msdn.microsoft.com/visualc/vctoolkit2003/ Hope this helps (been there, done that, got the tee-shirt :) ) --- Rohit O chokhani wrote:

Hi, i am a rookie as far as boost is concerned and i am trying to make boost work but just cant...on the point of giving up on it...so please help asap....

i am trying to use a scripting language called lua with my c++ source code. FOr that I felt the need to use luabind library which is completely dependent on boost.(project specific reasons for selecting luabind)

As a result i need to have boost on my system. For the past 3-4 days ever since i have been trying to make boost works i have been getting all sorts of compilation errors. mainly they are as follows:

C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(16) : error C2059: syntax error : 'string' C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(17) : error C2091: function returns function C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(17) : error C2809: 'operator new' has no formal parameters C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(20) : error C2954: template definitions cannot nest

C:\BOOST2\BOOST\boost/mpl/aux_/integral_wrapper.hpp(88)

: fatal error C1506: unrecoverable block scoping error Error executing cl.exe.

i did find some solutions of the various forums of boost recommending to build the latest version from cvs in order to get rid of the scoping issue. however, that hasnt solved my case.

could anyone kindly suggest some fixes, i would really appreciate it, thanks and regards, rohit
