I'm struggling to get Boost built on a Solaris box here. Initially I was stuck on compilation errors due to v8plus issues. After some googling and trial and error I worked out what to put in user-config.jam to fix that. However, I'm now struggling with the following error:

... wrong ELF class: ELFCLASS64

What is the exact error message, and what is the command that produces this error?

I'm using gcc-3.2 and the Sun linker, trying to build a 64bit version of just the program_options and regex libraries. Here's what I've got for the user-config.jam:

using gcc : : : <address-model>64

This one has no effect here.

<linker-type>"sun"

I'm surprised that quotes work here

<compileflags>"-m64" <linkflags>"-Wl,64"

I don't know about such option; I think passing -m64 to the linker might work better.

<instruction-set>"v9" ;

This probably has no effect either.

I'm basically flummoxed at this point, and my google-fu is failing to find me a solution. All the object files are 64bit so I don't know why it is complaining as it should be doing the link as 64bit.

I'd suggest changing user-config.jam to: using gcc : : : <linker-type>sun ; and building as: bjam address-model=64 instruction-set=v9 - Volodya
