Boost Package Manager

bpm

bpm, the Boost package manager, is an experimental utility for installing parts of Boost from modular "releases".

To build it, this repository needs to be cloned into the tools/bpm subdirectory of the Boost superproject, then b2 tools/bpm/build will place bpm into dist/bin.

To try it out, make an empty subdirectory and create a text file bpm.conf there with the following contents:

package_path=http://www.pdimov.com/tmp/pkg-develop-1612497/

then to install, for example, the filesystem library along with its required dependencies, execute bpm from that directory with

bpm install filesystem

You can also run bpm without arguments, and it will display a description of the commands and options it takes.

The "release" specified in package_path above has been prepared by running tools/bpm/scripts/package.bat at the root of the Boost source tree, revision develop-1612497.

bpm's Issues

Unable to build bpm when compiling with address-model=64

When building a 64-bit version of bpm a compiler error because

sizeof( state_ ) >= sizeof( CLzmaDec )

is false in line 28 of lzma_reader.cpp:

typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];

Is this intended to fail for 64-bit compilation ? Using mingw-w64/gcc-9.2 the message in 64-bit compilation the message is:

..\src\lzma_reader.cpp:28:85: error: narrowing conversion of '-1' from 'int' to 'long long unsigned int' [-Wnarrowing]
   28 |     typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];
      |                                                                                     ^
..\src\lzma_reader.cpp:28:77: error: size '-1' of array 'assert_large_enough' is negative
   28 |     typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];
      |                                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~

while with msvc-14.2 in 64-bit compilation the message is:

lzma_reader.cpp
..\src\lzma_reader.cpp(28): error C2118: negative subscript

Doing a 32-bit compilation succeeds in both cases. Is bpm designed to only work as a 32-bit application ?
