thanks again brian.Like u said, i also thought about project settings and made sure I had set the various options and linker specifications correctly...well, i solved a lot of issues and i am down to 12 errors from initially 122. Which is quite a relief, but these last 12 are still an issue taking away a considerable time of mine. I am working on them right now but do let me know if you have any clue. They are mainly some issues with luabind and boost. I have just made #include references to luabind and boost. Havent included any .libs for them, so it would be great if you let me know if there are any specific .libs for the same that need to be added to the project settings. APart from that I have made sure that the various include and lib directory paths have been set correctly. I am attaching the error message below, thanks again in advance, regards, rohit Linking...

I am *not* an expert on bjam (working on it though) but I know just in the VC world, you WILL get errors like below if you do not have your debugging and threading models all set the same. I would also suggest to you if you setup JUST VC projects for EVERYTHING and get everything to build properly in the MS tool (I am not sure if below is bjam or not) that will at least get you to something that works and it will be easier to take the bjam step from there. You can also make a solution- and then add the individual project files under that one "parent solution" which will make the above steps easier. I hope something there helps (and good luck)..

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:

do these link post sound familiar with something you have seen before or they could be my code 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

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

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

compiler is available for free download from: http://msdn.microsoft.com/visualc/vctoolkit2003/

Hope this helps

(been there, done that, got the tee-shirt :) )

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
