Dear all, I can't build boost 1.57 for MinGW on Win7. I tried D:\boost_1_57_0>bootstrap.bat mingw D:\boost_1_57_0>.\b2 toolset=gcc install and I only got D:/boost_1_57_0/tools/build/src/tools\msvc.jam:1075: in configure-really *** argument error * rule generate-setup-cmd ( version : command : parent : options * : cpu : global-setup : default-global-setup-options : default-setup ) * called with: ( 9.0 : C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin : C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC : <command>C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\cl.exe : i386 : : x86 : vcvars32.bat ) * missing argument global-setup D:/boost_1_57_0/tools/build/src/tools\msvc.jam:809:see definition of rule 'generate-setup-cmd' being called D:/boost_1_57_0/tools/build/src/tools\msvc.jam:201: in configure D:/boost_1_57_0/tools/build/src/tools\msvc.jam:153: in msvc.init D:/boost_1_57_0/tools/build/src/build\toolset.jam:43: in toolset.using D:/boost_1_57_0/tools/build/src/build\project.jam:1007: in using project-config.jam:3: in modules.load D:/boost_1_57_0/tools/build/src\build-system.jam:249: in load-config D:/boost_1_57_0/tools/build/src\build-system.jam:412: in load-configuration-files D:/boost_1_57_0/tools/build/src\build-system.jam:524: in load D:\boost_1_57_0\tools\build\src/kernel\modules.jam:289: in import D:\boost_1_57_0\tools\build\src/kernel/bootstrap.jam:139: in boost-build D:\boost_1_57_0\boost-build.jam:17: in module scope What is wrong?
