# Boost and VC++ Express fatal link error

## Recommended Posts

Well, I decided to bite the bullet and install Boost. After much faffing about trying to follow the cryptic and arcane instructions at Boost.org and heavy use of Google I was finally able to build it using bjam. However, now I'm trying to build a short test console program
#include <iostream>
#include <cassert>
#include <string>
#include "boost/regex.hpp"

int main()
{
boost::regex reg("\\d{3}([a-zA-Z]+).(\\d{2}|N/A)\\s\\1");

std::string correct="123Hello N/A Hello";
std::string incorrect="123Hello 12 hello";

assert(boost::regex_match(correct,reg)==true);
assert(boost::regex_match(incorrect,reg)==false);
}

and I'm getting the following error.
LINK : fatal error LNK1104: cannot open file 'libboost_regex-vc80-mt-gd-1_33_1.lib'

I've scoured Google and GameDev.net, messed about with project settings and the vsvars32.bat file but all to no avail. Any help or suggestions as to how sort this would be most appreciated. [smile] TIA A5

I really fail to see why people have such a problem building boost. The instructions are perfectly clear. Which part did you have problems with?

Do you have a successfully built libboost_regex-vc80-mt-gd-1_33_1.lib file? Is it on the libs path for your project?

Hi Snigma (I really fail to see why people can't be bothered to learn the Greek alphabet... Σ = sigma hence has an "ess" sound.)

Do you really want to get into that? I'm afraid that I didn't find the instructions perfectly clear, e.g.
Quote:
 The user sets up all of the environment for each toolset he wants to use in the normal way.
Toolset? Environment? Normal way?!? Sorry, lost me right there. And I'm afraid it just gets worse after that. (Truthfully, earlier discussion of cvs, .tar.gz, .tar.bz2, boostbook, Perforce etc. confused the blazes out of me.) Maybe I'm just too stupid to live.

During the build process I opened a command prompt from VCEE, and had to
set INCLUDE=C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Include;%INCLUDE%
and
set LIB=C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Lib;%LIB%
to get a successful(?) build.

libboost_regex-vc80-mt-gd-1_33_1.lib can be found in
C:\boost\bin\boost\libs\regex\build\libboost_regex.lib\vc-8_0\debug\threading-multi\ on my machine, so, I assume it built successfully.

Tools-> Options-> Projects and Solutions-> VC++ Directories (Include files) and
C:\boost\lib to
Tools-> Options-> Projects and Solutions-> VC++ Directories (Library files).
Do I need to more? (I can't find where it explains which setting are required.)

TIA

If you point the library directory at some place, and have the library file somewhere else, then of course it can't find it. You probably just build the files, but didn't install it. Check step 5 in the getting started guide. Building without the install-option will just build the files, not collect them in any specific place.

Building boost takes a bit of reading, yeah, but all the information you need are in the documentation. (Specifically, this page shows you 1) Which toolsets you can choose between (and once you see the list, it should be fairly obvious what they mean by toolset. [grin]), and 2) which arguments you can pass to bjam:

bjam [options...] [install|stage]

And just below this line, it tells you what install and stage does. It also tells you the possible options you can supply. So all that's left now is to fill in the couple of options you find relevant.

As for the bit about .zip (you know what a zip file is, right?), .tar.gz and cvs, well, they're all listed under the Download section, which could be a hint that they refer to simply different ways to download boost, and different file formats. In other words, once you have downloaded the files, you don't need to worry about this section.

I'm perfectly aware of the Greek alphabet thankyou. I use the Sigma as a stylised E. I've also been known to go by the moniker 'Snigma' when Enigma is unavailable.

Sorry, I meant "clear to me". However, the the sentence following "The user sets up all of the environment for each toolset he wants to use in the normal way." is "For example, for Microsoft VC++, ...VC98/Bin or .../VC7/Bin is in the PATH environment variable, VCVARS32.BAT or VSVARS32.BAT has been invoked, etc". Is that really that's hard to understand?

I mean, come on. Boiling down the instructions to remove information which is not relevant to you:
1. The Boost Libraries are distributed through the SourceForge file distribution system. Click here to download releases from SourceForge. And unpack the release to a convenient location.

2. The build system uses Boost.Jam, an extension of the Perforce Jam portable make replacement. The recommended way to get Boost.Jam if you are using a Boost distribution is to download a prebuilt executable from SourceForge. ... To install Boost.Jam, copy the bjam executable to a location accessible in your PATH.
[short version: boost has it's own build system. Get it from the given link. Make sure your operating is able to find bjam by making sure it's on the system path]

3. Before using Boost.Build you will need to configure the compiler tools you are using. The build system's toolsets are designed to work in either of two ways:
1. The user sets up all of the environment for each toolset he wants to use in the normal way. For example, for Microsoft VC++, ...VC98/Bin or .../VC7/Bin is in the PATH environment variable, VCVARS32.BAT or VSVARS32.BAT has been invoked, etc.
[short version: make sure your compilers bin directory is on the system path (scroll down to discussion of "The PATH Environment Variable"), so that it can be invoked from the commandline without supplying a full path. Run VCVARS32.bat or VSVARS32.bat]

4. First you need to change to the directory where you have the Boost distribution you downloaded. For example:
chdir boost-1.31.0
[short version: navigate to the directory where you extracted boost to]

5. Invoke the build system, specifying the toolset(s) you wish to use, to build and install.
[short version: type bjam "-sTools=vc-8_0" install <enter>]

I opened a command prompt,
changed my working directory to c:\boost
then typed bjam "-sTOOLS=vc-8_0" install

did I miss something?

Okay, so you added those two last directories to your compiler configuration. Do those directories even exist? It looks like the bjam utility didn't copy those files to the include or library directories. I'm not sure if that's what bjam is meant to do or not (I just used the installer package found at Boost Consulting )

Yes, those directories do exist.

I had thought about using the Boost Consulting installer package, but it states that it's for Visual C++ 7.1 and/or 8.0. Is it compatible with VC++ Express? And how would I go about removing the existing botched "installation? I can then either try again from scratch or use the Boost Consulting installer package.

It's just so damned frustrating that I (and others) find installing Boost so difficult and frustrating. I really would love to know out where I'm going wrong. Hey, that's how we learn from our mistakes.

If that's what you did, and you haven't changed any other parameters somewhere, you must have missed something. Are you sure the install script finished successfully?

AFAICT, there's a bug in the new bjam system which makes the outputted libraries have a "vc" identifier instead of a "vc80" identifier if you follow the posted instructions. If you like, you can simply add the "80" after the identifier yourself and things will work fine. Alternatively, edit the tools/build/v2/user-config.jam file and add "using msvc : 8.0 ;" on a line at the end, then rebuild (leaving out the toolset argument).

Have you followed the cut down instructions exactly as I posted (minus typos)? What messages did you get back from bjam it terms of targets built/updated?

Well, it'll be compatible with Visual C++ 8.0 Express Edition, which I assume is what you have.

Am i missing something? You say the .lib file is in "C:\boost\bin\... and so on", and then you say this:

Is "C:\boost\bin" set up in your VC++ directories?

Well, b*gg*r me bandy. It seems to have worked. The only difference between your list of steps and what I had done previously was running VCVARS32.bat.

Now, I'm just a bit worried that I've got piles of garbage left from my earlier attempts, which I'll try to clear up.

Many thanks for the assist to everyone (and Σnigma in particular cos you were right... smart alec [wink]).

I guess I'll have to learn what Boost can do, now.

Right, let's see what a mess I can make of Ogre (no binaries for Crystal Space sigh).

A final point, I suppose this shows that the instructions on the Boost site aren't all that clear as I was able to follow Σnigma's quite well, but not theirs.
