Hi, I am trying to cross-compile Boost 1.44.0 for a powerpc on my Fedora 13 x86 workstation. I have written a bash build script do this build. It has worked fine for previous version of boost. i.e. 1.37.0, 1.40.0, 1.43.0 But when I tried to build 1.44.0 I get the following errors. libs/regex/build/has_icu_test.cpp:12:30: error: unicode/uversion.h: No such file or directory libs/regex/build/has_icu_test.cpp:13:28: error: unicode/utypes.h: No such file or directory libs/regex/build/has_icu_test.cpp:14:27: error: unicode/uchar.h: No such file or directory libs/regex/build/has_icu_test.cpp:15:26: error: unicode/coll.h: No such file or directory libs/regex/build/has_icu_test.cpp:26:2: warning: no newline at end of file libs/regex/build/has_icu_test.cpp: In function 'int main()': libs/regex/build/has_icu_test.cpp:23: error: 'UErrorCode' was not declared in this scope libs/regex/build/has_icu_test.cpp:23: error: expected `;' before 'err' libs/regex/build/has_icu_test.cpp:24: error: 'UChar32' was not declared in this scope libs/regex/build/has_icu_test.cpp:24: error: expected `;' before 'c' libs/regex/build/has_icu_test.cpp:25: error: 'err' was not declared in this scope ...failed updating 1 target...

I have seen that other people have had similar problems. See here. http://lists.boost.org/boost-users/2010/09/62265.php But I have not been able to fix it. Any ideas. Thanks Rob
