Hi all! I have a very basic problem with the boost libraries: I used bjam to build all boost libraries for Linux (using "gcc" as toolset and the call 'bjam "-sTOOLS=gcc" install'). All went fine, however I wanted to do the regression tests for boost_regex using the gcc.mak Makefile in <boost_main>/libs/regex/test/regress which uses "-lboost_regex" for linking. The linker reported an error because there is no "libboost_regex.so" in my lib folder unless I created a link with this name to one of the various versions of libboost_regex. A comment for these Makefiles would be helpful for the case when having build all with bjam. When compiling the regex part alone, the library is created in build/gcc with the correct name (libboost_regex.so). I'm new to C++, so maybe I haven't got the point with the sophisticated naming scheme of the libraries, but: for the library "libboost_regex-gcc-mt-d-1_31.so" e.g. are the tool specifier ("gcc") and the version ("1_31") really necessary for a platform using version numbering of the libraries anyway in the ".so" extension? OK, there are still the categories with/without debug and with/without threading. How would you guys select the type of library? In the Makefile? Thanks in advance!
