Hello I have sucessfully compiled the Boost Library, but I can`t use it. I get a error an the programm chrashes. I have testes it with the files in the example folder. Perhaps anyone can give me a hint, how I get ahead or where my error lies? Which I did: 0) Executed Borland builder Patch No. 4 1) Downloaded Spirit 1.6.3, set environment variable SPIRIT_ROOT on the Spirit listing 2) Set environment variable BCCROOT on c:\programme\borland\cbuilder6 3) Dowloaded the Boost LIBRARY (tried one after the other from 1_32-1_33 beta, all versions), and set the BOOST_ROOT environment variable to the listing in which I boost unpacked. 4) At the Boost tools\build\listing\build.bat executed (compiles correctly for Boland) 5) Executed tools\build\jam_src\bin.ntx86\bjam.exe "- sTOOLS=borland" install (compiled also, but with few warnings) 6) At the listing, in which I unpacked Boost, I started the libs\thread\example file once.cpp 7) I made a Porjekt to compile the file 8) I set atthe project settings the include path on C:\Boost\include\boost-1_32 9) I set atthe project attitudes the LIBRARY path on C:\Boost\lib \ 10) The program compiled and linked 11) When starting the project it crhases immediately and started the monitor, which indicates the storage addresses to me. Where does my error lie? Do I have to adjust something special in the Porjekt still? Many greetings from Hamburg, Jens
