Hi all, I have a problem with building program_options on VC 7.1. It is only related to program_options in that this is one of the boost libs with the longest names. The problem is the path length of files generated during build. As an example, there is a file generated with the name bin/boost/libs/program_options/build/libboost_program_options.lib/vc-7_1/debug/native-wchar_t-off/threading-multi/libboost_program_options-vc71-mt-gd-1_33.CMD which amounts to 158 characters in length. As the path to the leading bin directory is already 100 characters long, I cannot build (max. 254 characters on NTFS). Besides shortening the preceding path, is there any other solution (like customizing the generated path)?
