>Description:
I have gcc installed in a nonstandard place so on the first
run gen_lex_hash failed becuase it could not find libstdc++.so.2.10.0.
I did a 'make distclean' and the reran configure with correct flags.
Unfortunately the build failed again, this time in another place.
Eventually I traced it to the fact that the failed first run
created an empty lex_hash.h and 'make distclean' did not remove this
file. Future builds did also not rebuild it.
>How-To-Repeat:
Try to build on a system where libstdc++ is not in the standard
library directory path.
>Fix:
By judging from the comments in sql/Makefile.am people have looked
at this previously but not found a satisfactory solution. Ideally
one would like to have lex_hash.h removed by 'make distclean' but
it seems automake makes that hard.
I would suggest that you change the line in sql/Makefile.am which
generates lex_hash.h from
./gen_lex_hash$(EXEEXT) > $@
to
./gen_lex_hash$(EXEEXT) > [EMAIL PROTECTED]
mv [EMAIL PROTECTED] $@
If gen_lex_hash fails then it is a temporary file which gets created.
and that does not matter on the next run.
