bcp --namespace breaks path to import boost_install in Jamroot

[jbmercha]

When using bcp.exe to create a boost subset with a new namespace, building the subset is broken because in the Jamfile the import for boostinstall has had the "boost" portion renamed to the new namespace.

Build\boost>.\dist\bin\bcp.exe --namespace=myboost --namespace-alias regex log headers predef config build boost_install ..\foo
Build\boost>cd ..\foo
Build\foo>.\bootstrap.bat
Build\foo>.\b2 toolset=msvc-14.1 --with-regex --with-log
boost-install.jam: No such file or directory
Jamroot:307: in boost-install
ERROR: rule "boost-install.boost-install" unknown in module "Jamfile<Build\foo>".

This issue was introduced with Boost 1.70 and prevents us from updating.

@pdimov After looking at the commit log I suspect https://github.com/boostorg/boost_install/commit/90b1f04f4485c06f907ecba6a92b7144bf211014 might be the cause.

This should be fixed with https://github.com/boostorg/boost/commit/d0586e88122f41cd5ac9666db70c37d6f0fc7480.

Thanks. I applied the patch locally but I still get the same error.

What command are you using? Note that without https://github.com/boostorg/bcp/pull/5, you need to manually add headers and boost_install to the bcp command.

I am using https://github.com/conan-community/conan-boost with boost:namespace = boost_ns and boost:namespace_alias = True. I will see if I can find the actual commands being used in the output.

Looks like you need to either add headers and boost_install to https://github.com/conan-community/conan-boost/blob/release/1.70.0/conanfile.py#L366, or patch bcp as per the above PR.

Thanks a lot - that seems to have done it (I added the libraries).

I will open a ticket with the boost-conan project so they are aware.
