Question

I have access to server where I need to build boost 1.46. How can I force bootstrap.sh to use /usr/bin/gcc-4.4. By default it uses /usr/bin/gcc and I can\'t figure out how t

Answer 1

With the most recent version of Boost 1.71 works the below way:

>export CC=/gcc
>export CXX=/g++
>./bootstrap.sh
>./b2 --toolset=gcc stage threading=multi link=shared

You could check the gcc version used for build with bellow command

>ldd b2
    linux-vdso.so.1 =>  (0x00007ffcaa5f4000)
    libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00002b85ab701000)
    libm.so.6 => /lib64/libm.so.6 (0x00002b85abaaa000)
    libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00002b85abdac000)
    libc.so.6 => /lib64/libc.so.6 (0x00002b85abfc3000)
    /lib64/ld-linux-x86-64.so.2 (0x00002b85ab4dd000)
