What does “ls -ld /usr/lib64/ruby” tell you? Does the user have
permissions to access the directory?

Cheers

Looks OK.

ideamax@usqlh07d2:~> cd /usr/lib64/ruby
ideamax@usqlh07d2:/usr/lib64/ruby>

ideamax@usqlh07d2:/usr/lib64/ruby> ls -l

drwxr-xr-x 3 root root 4096 2011-02-28 22:21 vendor_ruby

Now I’m confused. In your screenshot there is a ruby.h in that
directory. Now there isn’t. I’d say you found the source of the
error. You should probably check your ruby installation. How did you
install ruby?

Cheers

hi these are the steps followed from
http://www.rubyenterpriseedition.com/documentation.html

tar xzvf ruby-enterprise-x.x.x.tar.gz

PREFIX=/opt/ruby-enterprise

cd ruby-enterprise-x.x.x/source/distro/google-perftools-*
./configure --prefix=$PREFIX --disable-dependency-tracking
make libtcmalloc_minimal.la

sudo mkdir -p $PREFIX/lib
sudo rm -f $PREFIX/lib/libtcmalloc_minimal*.so*
sudo cp -Rpf .libs/libtcmalloc_minimal*.so* $PREFIX/lib/

cd …/…

5)./configure --prefix=$PREFIX --enable-mbari-api CFLAGS=‘-g -O2’

6)Open Makefile. Search for a line which starts with:
append the string $(PRELIBS) to the part after the = sign. for me it
came like this

LIBS = $(PRELIBS) -lrt -lcrypt -lm $(EXTLIBS)
upto here worked fine but while running
the script like this
make PRELIBS=“-Wl,-rpath,$PREFIX/lib -L$PREFIX/lib -ltcmalloc_minimal”
i am facing error…I am attaching the same screen shot.kindly resolve
it.would be a help for me.
