Gem update fails with "checking for fcgiapp.h... no"

Rails

Hello,
Trying to do gem update on my existing system that’s been working fine
for a couple of months. This is what I get:

bash-2.05b# gem update
Upgrading installed gems…
Attempting remote upgrade of fcgi
Attempting remote installation of ‘fcgi’
Building native extensions. This could take a while…
ERROR: While executing gem … (RuntimeError)
ERROR: Failed to build gem native extension.
Gem files will remain installed in
/usr/local/lib/ruby/gems/1.8/gems/fcgi-0.8.6.1 for inspection.
ruby extconf.rb update\nchecking for fcgiapp.h… no
checking for fastcgi/fcgiapp.h… no

Results logged to
/usr/local/lib/ruby/gems/1.8/gems/fcgi-0.8.6.1/ext/gem_make.out

bash-2.05b# more

ruby extconf.rb update
checking for fcgiapp.h… no
checking for fastcgi/fcgiapp.h… no

Any ideas what could be wrong?

Thanks for any help…

solved it…
fcgipp.h was in /usr/local/include
symlinking to /usr/include solved it.

explain?

He made a symbolic link (“symlink”) to that file. Since this is an OS
concept and not a Rails one, I think I should refer you to Google before
we go off topic.

The solution is to install gcc

and libc6-dev

My case is Ubuntu 8.04.3 LTS (hardy)
use:

apt-get install rubygems libc6-dev gcc libfcgi-dev ruby1.8-dev
gem update
gem install rails -y

not only:
apt-get install rubygems
…

In my case the problem was:

cc -E -I. -I/usr/lib/ruby/1.8/i486-linux -I. -fno-strict-aliasing -g

-g -O2 -fPIC conftest.c -o conftest.i

bash: cc: command not found

The solution is to install gcc
