When building on normal windows + mingw then it worked simmilar to this
point

now the error:

So perhaps the objcopy utility used is wrong?

raf256_at_lore:~$ /usr/bin/objcopy -V

I dont have no objcopy in mingw, only objdump

raf256_at_lore:~$ /usr/i586-mingw32msvc/bin/objdump -V
GNU objdump 2.16.91 20050827

perhaps missing objcopy is causing mingw-running-on-linux to fail?

Can that be fixed in bjam, like by using other tool or telling linux
objcopy how to work with crossbuilded objects?

The cmd line that worked fine on win32 was:

setting path to:
D:\WINDOWS\system32;D:\WINDOWS;D:\WINDOWS\system32\WBEM;
C:\bjam;C:\mingw;c:\mingw\bin;
(in one line) or simmilar,

then:

C:\boost_1_33_1>bjam -sTOOLS="mingw" -sMINGW_ROOT_DIRECTORY="c:/mingw"
install
