Linking fails with CFG=release

[FreeFull]

If I compile klystrack with CFG=debug or CFG=profile, it succeeds as expected, but with CFG=release I encounter this error during the linking phase:

$ make RES_PATH=. CFG=release

Linking klystrack...
/usr/bin/ld: ../klystron/bin.release/libengine_util.a(util_rnd.o): relocation R_X86_64_32S against `.bss' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output

Sorry, this was an error on my part. Turns out I had to do make clean inside the klystron directory
