[mercury-users] dynamic linking..

[Robert Ernst Johann JESCHOFNIK]

Hello.

I just uncovered something a bit odd whilst playing with dynamic linking
on my linux system.
If I set the following flag in the Mmakefile:
(along with EXTRA_MLFLAGS = -shared  in both cases)

MGNUCFLAGS    = -DML_OMIT_ARRAY_BOUNDS_CHECKS --pic-reg

I get this error during make (whilst mgnuc is running)
cc1: Invalid option `-fpic-reg'

However, with the two flags reversed,
MGNUCFLAGS    = --pic-reg -DML_OMIT_ARRAY_BOUNDS_CHECKS

I get no such error, and everything compiles just fine. Is there any
particular reason for this?
