There are still some remaining issues which I like to discuss in this thread:

1. building these libs sometimes requires renaming header and/or source files to the correct architecture. Should we leave that up to the user or should bjam take care of it. And if so, how will we configure that. One example is jpeg: see jconfig.vc -> jconfig.h

What I've done in the past to handle that is to generate a header file in the correct build specific dir that includes the correct library header.

You are correct that's a way to do it. But I'm looking for a solution that would be a bit more automatic. Like the user downloads the lib source code and adds the location to the user-config.jam. Boost build will take it from here.

2. Tiff has a file nmake.opt which is included in the makefile. How will

we

include all those options?

Not sure without looking at the file.. but there are two options:

1. Recreate the logic in b2 and generate a global header or b2 options.

2. Have b2, or some other script file, parse the options file and generate a header or b2 options.

I prefer the user to add the symbols inside user-config.jam. Of course a template will be provided by the documentation. What do you think? But I'm a little afraid the time to implement all of my wish list will be too long and possibly too steep. Since I'm a complete noob to boost build I have to rely on people like Steven. And I'm sure they have better things to do... Regards, Christian
