[solved] fpc.cfg with switch -Xd
lazarus / 1-Linux

For cross compilation I have to avoid reading from /usr/lib. It works
well with "-Xd /usr/lib" at lazarus->compiler settings->additional (or
however the english translation is). If I place the switch into
fpc.cfg like
Code: [Select]#ifdef x86_64
-Fl/usr/lib
#else
-Xd/usr/lib
-Fl/usr/lib32
#endifit fails with "Error: Illegal parameter: -Xd/usr/lib". Any idea
how to solve?

Linux (Ubuntu 9.04)
Lazarus 0.9.29 (r22308M)
FPC 2.5.1 (Rev 14211)

I don't know why it works in the Lazarus compiler settings, but the
reason that it fails on the command line is that -Xd doesn't take any
additional parameters. "-Xd" by itself means "Do not use standard
library search path". You don't have to and cannot specify the
directories that it should not search. The standard library search
paths are hardcoded in FPC, and -Xd simply tells the compiler not to
search these directories.

That was the reason! Thanks a lot. Within the compiler settings I had
to apply a blank, and apparently the remaining string was ignored
there and not in the cfg.
