Hi there, typically I modify CFLAGS variable to include a pure static version before compiling, as in:   CFLAGS='-static' This works for sed, grep, bash etc.. easily, but for ruby, this does not seem to work as straight forward. If i invoke certain scripts that use md5 or similar "add-ons" I get errors such as:   [socket.so](http://socket.so): undefined symbol: rb\_eSecurityError Sometimes different rb\_e\* Errors occur. Someone else said that I should modify ext/Setup but I am wondering whether this is the default route one has to follow to get to a static version of ruby? One reason i'd like to have it all inside one ruby binary is that I dont want to have it fail if a host lib is missing or broken. (The size penalty is of no concern at all to me.) > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/). ---

Along with Nobuyoshi's excellent advice, make sure you look in the etc/Setup file. You will probably need to edit it to select which libs to include by default. Very useful for making small static ruby distributions you can move from machine to machine. --Kyle > **···** > > On Mon, Mar 24, 2008 at 1:39 PM, Marc Heiler \ wrote: > > > Hi there, > > > > typically I modify CFLAGS variable to include a pure > > static version before compiling, as in: > > > >   CFLAGS='-static' > > > > This works for sed, grep, bash etc.. easily, but for ruby, > > this does not seem to work as straight forward. > > > > If i invoke certain scripts that use md5 or similar "add-ons" > > I get errors such as: > > > >   socket.so: undefined symbol: rb\_eSecurityError > > > > Sometimes different rb\_e\* Errors occur. > > > > Someone else said that I should modify ext/Setup > > but I am wondering whether this is the default route one > > has to follow to get to a static version of ruby? > > > > One reason i'd like to have it all inside one ruby > > binary is that I dont want to have it fail if a host > > lib is missing or broken. > > (The size penalty is of no concern at all to me.) > > -- > > Posted via [http://www.ruby-forum.com/\](http://www.ruby-forum.com/%5C). ---

Hi there, Sorry for the late reply, I didn't get to recompile ruby for some time. I did it now with the latest 1.8.7, thanks to Nobuyoshi's hint. The compile part worked out nicely, the resulting ruby bin/ dir took about ~ +1.8 MB in size. However there were two problems, and I played a bit with it inside ext/Setup as Kyle suggested but to no real avail (uncommenting #openssl and #fcntl and recompiling lead to some weird effect ruby was working but the sizes inside the ruby bin/ dir were suddenly as small as the shared versions...) One problem was this here:   ssl.rb:19:in `require': no such file to load -- fcntl The other was OpenSSL related.   openssl/ssl.rb:26: uninitialized constant OpenSSL::SSL::VERIFY\_PEER I am a bit at a loss now 🙂 Also, if I do a "ldd ruby" i get a lot of libraries listed. But if i normally do a ldd on a static binary, like this "ldd grep" I get:         not a dynamic executable Appreciate more help, and thanks a lot for the pointers so far! > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/).
