The boost macros at the autoconf library are pretty good if you're using autoconf: http://autoconf-archive.cryp.to/. I had to add one case to AX_BOOST_FILESYSTEM to cope with 1.34 in the line that starts "for ax_lib in... ", so I expect that will be true for the other libraries too, but at least it has the logic to look for something that works! Rupert

I too have a similar problem as Christoph. In my case I'm always using version 1.34, but I'm building on different machines that have different versions of the gcc compiler. I want to write just one makefile that will find the boost libraries without needing to specify the version of the compiler being used. In other words, if gcc 4.0 is being used, the makefile should locate a library with the toolset part of the name being "gcc40". Similarly if gcc 4.1 is being used, it would specify "gcc41". Do I actually need to modify my makefile to figure out what gcc version I'm using and construct the library name dynamically? I preferred the 1.33.1 and older method of just having the toolset being "gcc" in the libraries file name. Christoph Duelli wrote:

Thank you and best regards Christoph
