I assume you built the libary and included a path to it in your project file? The issue is you can't link with the methods built into the library. We will have to wait for John if this is supposed to to work magically with the autolink stuff...

It may be operator error here also... see my other message but NO documentation anywhere suggests that enforcing standard C++ using MSVC will affect one's ability to use any of the boost libraries. I've found that using the /Za option breaks a lot of things for using boost. I believe we've gone a bit overboard in our requirements for MSVC for example, all of my date_time stuff works JUST fine....even using /Za if I simply add a line to auto_link.hpp which will accept _MSC_VER >= 1310 I note that another test from a colleague (boost threads) won't compile if /Za is turned on. the visualc.hpp file in config turns off the Win32API if extensions aren't enabled. Say what?? what do the language extensions have to do with libraries being called? I'll be happy to add my small tests to the test suite as soon as I figure out how to incorporate them... right now, I just build 3 different "solutions" I have every morning after updating from CVS.

I'm not able to reproduce the problem here. I just tried again to be sure. In the recent past, I have sometimes had trouble getting libraries to resolve, but it has always turned out to be operator error on my part.

If you think we should be doing additional testing, great. Develop a set of tests and submit them. But that isn't something for 1.31.0.

I understand that it won't work for SOME things. I think boost are complaining TOO much about it though. We do us wchar_t and forScope already, I was working under the assumption (probably erroneous) that /Za would help me w/ portability issues. At Tuesday 2004-02-03 14:28, you wrote:

I think that's because boost threads are using Windows API. Unfortunatelly <windows.h> (and other Platform SDK headers) cannot be compiled without language extensions. Besides obvious stuff, like __dllimport , there are other problems like anonymous structures etc. So, currently you simply cannot use /Za switch with some libraries :( However, I'd recommend using /Zc:wchar_t and /Zc:forScope switches instead of /Za everywhere - that will not cause troubles, if used consistently.

I haven't tested it so I can't be sure but I believe that if /Za is turned on, you can't include any windows.h without many errors occurring. I believe the windows.h header file has always failed when one is in C++ standard mode ( /Za ). There has been talk by MS of changing it to be C++ standard compliant but I don't think that has been done in VC7.1.

The problem is that with /Za you can't compile <windows.h> (or at least not last time I checked), there is also an assumption that libraries are compiled with the same options as your code, I appreciate that in some limited cases that isn't always a requirement, but it usually is....

Yesterday, I was looking through the 1.30.2 distribution in order to find out what the options were that bjam selected for the vc7.1 build, I found it a bit of a pain, perhaps it would be useful to make this a FAQ along with a note about ensuring you have selected the right compiler from the command line before bjam'ing (by running vcvars32.bat). Searching the web site didn't give many answers only hints, and I knew what was needed to fix the problem I had - the errors are not always that useful from the compiler :-) Perhaps there is some magic bjam invocation needed to output the CFLAGS so that the FAQ doesn't get out of sync with the version of boost.

Well, actually you may use most of boost without "language extensions" (with exception of threads and maybe few other libraries, depending on <windows.h>) . It's just that C++ standard does not have anything similar to autolink, thus this particular feature is depending on compiler extension. If you turn this extension off, you do not have autolink feature. B.

Works fine for me with current cvs-release-branch.

Can you try:

1) define BOOST_LIB_DIAGNOSTIC and verify that the name of the date_time lib that will be linked to gets printed out.

nothing gets printed out

2) If that fails, pre-process the source and verify that boost/config/auto_link.hpp is getting included.

I turned on "show includes" and it does NOT get included

3) If it's not then why not? Are you defining BOOST_ALL_NO_LIB or BOOST_DATE_TIME_NO_LIB ? Are your include paths correctly set up?

I define NO symbols in my code (except BOOST_LIB_DIAGNOSTIC). I use cvs to update my source tree and bjam to install. The files being included (according to the log from vs.net2003) are from the install directory I will attempt to get vs to give me the preprocessor output and see if I can figure out _why_ it's not including auto_link.hpp

However I do see some pesky warnings from vc7.1 that Jeff may want to try and suppress in future (reproduced below).

John.
