Building Boost and B2 using Intel OneAPI

[BryanFlynt-NOAA]

I've encountered 2 problems using the Intel OneAPI compilers. The first one I have the fix for but the second is more complex.

Problem 1 (Bootstrap):

Running bootstrap.sh with the intel-linux tool set insists on linking the application statically. Many OS do not include static libm.a, libdl.a and libc.a libraries but they do exist as shared libraries (*.so files). The other tool sets (GCC, etc.) do not impose this static requirement.

Linux Terminal Commands to Reproduce:

> cd boost_1_76_0
> ./bootstrap.sh --with-toolset=intel-linux
> icpx -x c++ -std=c++11 -O3 -s -static -DNDEBUG builtins.cpp class.cpp command.cpp compile.cpp constants.cpp cwd.cpp debug.cpp debugger.cpp execcmd.cpp execnt.cpp execunix.cpp filesys.cpp filent.cpp fileunix.cpp frames.cpp function.cpp glob.cpp hash.cpp hcache.cpp hdrmacro.cpp headers.cpp jam_strings.cpp jam.cpp jamgram.cpp lists.cpp make.cpp make1.cpp md5.cpp mem.cpp modules.cpp native.cpp object.cpp option.cpp output.cpp parse.cpp pathnt.cpp pathsys.cpp pathunix.cpp regexp.cpp rules.cpp scan.cpp search.cpp startup.cpp subst.cpp sysinfo.cpp timestamp.cpp variable.cpp w32_getreg.cpp modules/order.cpp modules/path.cpp modules/property-set.cpp modules/regex.cpp modules/sequence.cpp modules/set.cpp -o b2
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -ldl
/usr/bin/ld: cannot find -lc

The Fix:

Remove the "-static" flag from the intel-linux compiler flags at line ~334 of "tools/build/src/engine/build.sh" and b2 will build properly.

Problem 2 (Building Boost):

Running ./b2 appears to overwrite the system environment variables when building Boost to the incorrect locations.

Linux Terminal Commands to Reproduce (after b2 correctly built as above):

> cd boost_1_76_0
> ./b2

The missing library (libimf.so) exists within the first directory pointed at by the LD_LIBRARY_PATH environment variable. So it appears boost is overwriting the LD_LIBRARY_PATH environment variable when running ./b2
