Re: [Boost-users] Cross compiling boost libraries with gcc and us ing boost jam to crosscompile third-party library (Jambase problem)

There were some warnings, but the libraries have build.

I tried it with gcc 3.2.1 and gcc 3.4.4.

With gcc 3.2.1 I needed to add to bjam command line "-sGXX=arm-linux-g++
-D_REENTRANT" to compile it correctly.

I prefixed ar and objcopy to use arm-linux-ar and arm-linux-objcopy.

PS: I didn't use the program that uses boost on ARM yet.
