[Pw_forum] Espresso on Mac OSX 10.4

[fabrizio cleri]

Ciao to everybody,

A warning for those compiling with xlf under Mac OSX 10.4 ("Tiger"). You will most likely get the following linkage error:

 ld: Undefined symbols:
 _sprintf$LDBLStub
 _fprintf$LDBLStub
 _printf$LDBLStub

This is becoming a known problem in the Apple Developers' community, it seems to happen because these functions in Tiger are actually macros which translate into symbols in the System stub library which is not included on the link line.

In the case of a F90 compilation (I am using the IBM xlf compiler) the way around this problem is to link explicitly also the library /usr/lib/libSystemstubs.a by adding

-lSystemStubs

to the LDFLAGS in make.sys.

have fun,
fc
