Hi, In ghc/compiler/main/DriverFlags.hs machdepCCOpts includes a "-static" flag for some arches. Is this really necessary? I can't see any comments as to why, nor any real answers from a quick google. It causes this when compiling darcs on these arches: /usr/lib/ghc-6.2/libHSunix.a(User.o)(.text+0x2a2c): In function `s6T9_ret': : warning: Using 'getgrgid_r' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking which I assume would lead to too strict dependencies on glibc being necessary. Thanks Ian
