Обсуждение: little bug in current CVS

Hi,

after make clean, make failed with message:

make[2]: Entering directory /home/postgres/cvs/pgsql/src/backend'
prereqdir=`cd parser/ && pwd` && \ cd ../../src/include/parser/ && rm -f parse.h && \ ln -s $prereqdir/parse.h .
ln: ./parser: File exists
make[2]: *** [../../src/include/parser/parse.h] Error 1

Regards,    Oleg

Hm.  I bet your shell is failing to strip whitespace from the output of
pwd, so that the ln command ends up looking like
ln -s /home/postgres/cvs/pgsql/src/backend/parser /parse.h .

Can you check that theory by inserting an 'echo'?

you're right. shell is BASH_VERSION='2.04.0(1)-release'
Makefile looks too complex:
$(top_builddir)/src/include/parser/parse.h: $(srcdir)/parser/parse.h       prereqdir=`cd $(dir $<) && pwd` && \
cd$(dir $@) && rm -f $(notdir $@) && \         $(LN_S) $$prereqdir/$(notdir $<) .
 

We're already in src/backend directory, why not useln -sf parser/parse.h .

Try changing the second line to this

prereqdir=`CDPATH=: ; cd parser/ && pwd` && \
