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.

Does the regex lib go on to build OK?

Those compiler errors are from a configuration check that looks to see if ICU is present or not - you shouldn't actually see those messages at all (they should be suppressed and written to file rather like autoconf does).

Is there a bjam command line that reliably reproduces this?

John,

No, the regex lib does not go on to build. The compiler error: libs/regex/build/has_icu_test.cpp:12:30: error: unicode/uversion.h: No such file or directory is from trying to compile has_icu_test.cpp with my cross-compiler tools which do not have the icu libraries and header files installed. So it can not find unicode/uversion.h.

Why is it trying to compile has_icu_test.cpp when has_icu builds = no, as shown below in my output?

Performing configuration checks

- has_icu builds : no

I think you misread this output. The error message is from the configuration check -- exactly the check that causes "has_icu builds" to output "no". Besides slight inconvenience, this should not cause any problems, and regex should be built, albeit without ICU support.

Do you actually observe that regex is not built? If so, there must be some further error messages. Would you please put a complete build log somewhere?

I found my problem. I was building boost with the bjam -q option. When I build using the bjam -q option the build stops on the above error and does not build the libraries. I removed the -q and it ignored the above error, as you explained, and everything built fine.

Thanks, Rob
