--with-mysql-dir is the only switch that you need, or --with-mysql-
include and --with-mysql-lib


You're talking about RubyInstaller and combined with DevKit, correct?

If so, then don't install form inside bash or use *nix like paths.

If you have MySQL 5.1, you need:

1) RubyInstaller 1.9.1 installed
2) DevKit installed and configured (edit fstab as indicated in the
wiki)

 http://www.**--****.com/ 

3) From a Windows prompt, ensure Ruby and GCC works:

ruby -v
gcc --version

4) Have MySQL installed and know the path where its library is. If you
manually extracted it form the zip, remember the location.

5) proceed to gem installation and indicate the "ruby" platform to
force the compilation. Now use the path to MySQL

gem install mysql --platform ruby -- --with-mysql-include=C:/mysql/
include --with-mysql-lib=C:/mysql/lib/opt

I've indicated "opt" as library because is the "opt"imized version.

Please note that extracting or installing MySQL or Ruby or gems in a
path with spaces can be a problem. Try avoiding them to all cost.

Hope that helps.

5.Trouble building 64-bit Ruby 1.8.3 on Solaris 10/AMD64 

Hello, I'm attempting to build an AMD64 native Ruby interpreter on top
of Solaris 10 with gcc and have been running into a number of
problems.

The first is ensuring that the -m64 parameter, which instructs gcc to
build 64-bit executables, is passed correctly.  It seems like LDFLAGS
is ignored.

If I ./configure CC=gcc CFLAGS=-m64 LDFLAGS=-m64 and try to compile I get:

gcc -fPIC -m64 -I. -I../.. -I../../. -I../.././ext/bigdecimal -c bigdecimalc
gcc -Wl,-G  -L'../..' -o ../../.ext/i386-solaris2.10/bigdecimal.so
bigdecimal.o  -ldl -lm   -lc
ld: fatal: file bigdecimal.o: wrong ELF class: ELFCLASS64

Because the -m64 parameter was not being passed during linking (same
behavior occurs if I set the CC/CFLAGS/LDFLAGS) environment variables.

As a workaround, I tried creating a wrapper script called "gcc64"
which contains the following:

#!/bin/sh

/usr/sfw/bin/gcc -m64 $*

And it compiles successfully, however:

# make test
make: Warning: Illegal dependency list for target `.DEFAULT'
not ok system 1 -- ./sample/test.rb:1643
not ok system 2 -- ./sample/test.rb:1644
not ok system 3 -- ./sample/test.rb:1650
not ok system 4 -- ./sample/test.rb:1651
not ok system 5 -- ./sample/test.rb:1658
not ok system 6 -- ./sample/test.rb:1668
not ok system 7 -- ./sample/test.rb:1669
sample/test.rb:2037: Invalid char `\377' in expression
not ok system 9 -- ./sample/test.rb:1711
test failed
*** Error code 1

Okay, not good.  If I try to make install and install gems...

/root/rubygems-0.8.11/./post-install.rb:73:in `instance_eval': compile
error (SyntaxError)
/root/rubygems-0.8.11/./post-install.rb:73: Invalid char `\377' in
expression   from setup.rb:583:in `try_run_hook'

For some reason there's a corrupt looking character at the bottom of
the file.  If I edit the file with vim, it reports:

"post_install.rb" [Incomplete last line] 73 lines, 2018 characters

If I delete the offending line it solves *that* problem, but begins to
complain about other files in site_ruby having "Invalid char `\377' in
expression".  It seems like virtually every file in site_ruby is
affected.

Any ideas?
