Hi! I cant compile the Boost.Python library. I use Borland C++ Builder 5 (WinXP Pro). I tried really everything. I get always a LOT of errors. Here are some of my tries: No1 cd c:\libs\boost_1_30_0\libs\python\build bjam -sPYTHON_ROOT=c:\progsy\Python23 -sPYTHON_VERSION=2.3 -sTOOLS=borland i get: C:\libs\boost_1_30_0\libs\python\build>bjam -sPYTHON_ROOT=c:\progsy\Python23 -sPYTHON_VERSION=2.3 -sTOOLS=borland ...patience... ...found 1078 targets... ...updating 110 targets... borland-C++-action ..\..\..\libs\python\build\bin\boost_python.dll\borland\debug\runtime-link-d ynamic\numeric.obj ../src\numeric.cpp: Error E2401 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 69: Invalid template argument list Error E2040 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 69: Declaration terminated incorrectly Error E2231 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 130: Member cast_generator<Source,Target>::is_upcas t cannot be used without an object Error E2401 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 131: Invalid template argument list Error E2040 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 132: Declaration terminated incorrectly Error E2228 C:\libs\boost_1_30_0\boost/python/object/inheritance.hpp 132: Too many error or warning messages *** 6 errors in Compile *** and so on No2 cd c:\libs\boost_1_30_0\libs\python\build bjam -sPYTHON_ROOT=c:\progsy\Python23 -sPYTHON_VERSION=2.3 I get the same No3 cd c:\libs\boost_1_30_0\libs\python\build set PYTHON_ROOT=c:\progsy\Python23 set PYTHON_VERSION=2.3 bjam No4 cd c:\libs\boost_1_30_0\libs\python\build set PYTHON_ROOT=c:\progsy\Python23 set PYTHON_VERSION=2.3 bjam -sTOOLS=borland I dont know what to do...
