Still: If you find a linker error, that is filtered out, please post it, so we can extend the filter.

Re: [lazarus] Linking error
I sometimes only get: error while linking Well I tried renaming as.exe to as.old and the IDE reported the correct error, and didn't just spit out error while linking - so can't really reproduce the issue yet. I recall using Build All to solve the problem, but can't remember what the circumstances were. I'm sure I'll come across it some time if it is a true problem that affects me :) otherwise I'm just moaning. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Your questions certainly pointed me in the right direction and here was
the problem:
Unit pgcl uses postgres;
unit postgres {$LINKLIB pq} and uses dlllst
unit dlllst also {$LINKLIB pq}
However under Windows it should be {$LINKLIB libpq} in both files
Also make sure the compiler can find libpq.dll (adding the directory to
the compiler search path)
Thanks for the advice
