Hi I have a problem I don't know how to solve. I want to try an example from an article from Dr. Dobbs 'The Boost.Threads Library'. When I try to compile it I get a "Fatal Error error 1001: F1001 Internal code generator error". I need your help. I'm stuck with this problem. I use CodeGear(tm) RAD Studio 2007 Version 11.0.2902.10471 in a Windows XP SP3 and Boost 1.3.6.0 I have built Boos with complete option to use the libs in debug builds. The code is as follows: ****************************************************************** #pragma hdrstop #include <boost/thread/thread.hpp> #include <boost/thread/mutex.hpp> #include <boost/bind.hpp> #include <iostream> boost::mutex io_mutex; void count(int id); void count(int id) { for (int i = 0; i < 10; ++i) { boost::mutex::scoped_lock lock(io_mutex); std::cout << id << ": " << i << std::endl; } } #pragma argsused int main(int argc, char* argv[]) { boost::thread thrd1( boost::bind(&count, 1)); <= here occurs the F1001 fatal error boost::thread thrd2( boost::bind(&count, 2)); thrd1.join(); thrd2.join(); return 0; } ********************************************************************** The Output is: Genereringen startade 2008-10-23 11:11:15. __________________________________________________ Projekt C:\Documents and Settings\e-echapel\My Documents\RAD Studio\Projects\ThreadsLab\MutexLab1.cbproj (MakeOne mål): Mål _MakeOne: Mål BccCompile: c:\program files\codegear\rad studio\5.0\bin\bcc32.exe -D_DEBUG;NO_STRICT -D_RTLDLL;_NO_VCL -I"C:\Program Files\boost\boost_1_36_0";"c:\program files\codegear\rad studio\5.0\include";"c:\program files\codegear\rad studio\5.0\include\dinkumware";"c:\program files\codegear\rad studio\5.0\include\vcl";ThreadsLab;"c:\program files\codegear\rad studio\5.0\include\Indy10";"c:\program files\codegear\rad studio\5.0\RaveReports\Lib";C:\boost\include -y -v -vi- -k -r- -c -tWC -tWM -H=Debug\MutexLab1.pch -oDebug\MutexLab1.obj -w-par -Od -vi- -v MutexLab1.cpp MutexLab1.cpp(28,47): Fatal Error error 1001: F1001 Internal code generator error Genereringen av målet BccCompile i projektet MutexLab1.cbproj misslyckades.
