使用bjam交叉编译m68k的boost

Question

使用文档，我运行：

$ echo "using gcc : m68k : /opt/freescale/usr/local/gcc-4.2.125-eglibc-2.5.125/m68k-linux/bin/m68k-linux-gnu-g++ ;" >  tools/build/v2/user-config.jam
$ ./bootstrap.sh
$ ./bjam -d2 --toolset=gcc-m68k '-sBUILD=release static multi/single' link=static --prefix=/home/damann/coldfire/boost --layout=system --with-filesystem --with-system --with-thread --with-serialization --with-date_time install

这会给出以下错误：

error: toolset gcc initialization:
error: version 'm68k' requested but 'g++-m68k' not found and version '4.4.3' of default 'g++' does not match
error: initialized from

用户配置似乎被忽略了，尽管它是被读取的(在--debug-configuration中查看它)

Answer 1

我发现(至少在Linux上) bjam也会在用户的from目录中查找一个用户-config.jam-而我有一个(我在之前的构建中忘记了)-所以一个会覆盖我的工作。
