Question

I am trying to make the installation of boost library a little bit slower, because there too many calls to gcc in a short time, which increase my CPU temperature to its limit and crashes the system.

So I add this in /etc/site-config.jam

using gcc ; ; "sleep 10; g++" ;

However, it gives this error:

$ ./bjam install
/etc/site-config.jam:5: syntax error at keyword ;
/etc/site-config.jam:5: in load
rule sleep 10; g++ unknown in module pch.

/tmp/boost_1_40_0/tools/build/v2/kernel/bootstrap.jam:138: in boost-build
/tmp/boost_1_40_0/boost-build.jam:16: in module scope

How can I solve this?

Let me just duplicate the answer I gave on the boost-users mailing list.

Please refer to gcc setup documentation

The syntax is gives is:

using gcc : [version] : [c++-compile-command] : [compiler options] ;

In other words, you need to have ":" instead of the first and the second ";".
