Question

After completing all installation steps for the CommandT plugin, I get the error command-t.vim could not load the C extension when starting it. The ComamndT troubleshooting section gives this advice:

If a problem occurs the first thing you should do is inspect the output of:

  ruby extconf.rb
  make

During the installation, and:

  vim --version

And compare the compilation and linker flags that were passed to the
extension and to Vim itself when they were built. If the Ruby-related
flags or architecture flags are different then it is likely that something
has changed in your Ruby environment and the extension may not work until
you eliminate the discrepancy.

And it does indeed seem that there is discrepancy for me.

Output from make suggests cygwin’s gcc is using ruby 1.8:

gcc -I. -I/usr/lib/ruby/1.8/i386-cygwin -I/usr/lib/ruby/1.8/i386-cygwin -I. -DHA
VE_RUBY_H    -g -O2    -std=c99 -Wall -Wextra -Wno-unused-parameter -c ext.c
gcc -I. -I/usr/lib/ruby/1.8/i386-cygwin -I/usr/lib/ruby/1.8/i386-cygwin -I. -DHA

gcc -I. -I/usr/lib/ruby/1.8/i386-cygwin -I/usr/lib/ruby/1.8/i386-cygwin -I. -DHA

e-auto-image-base,--enable-auto-import,--export-all   -lruby  -ldl -lcrypt

Output from vim’s :version contains this output:

-DDYNAMIC_RUBY_VER=191 -DDYNAMIC_RUBY_DLL=\"msvcrt-ruby191.dll\"

The troubleshooting guide suggests using a combination of Vim 7.2, Ruby 1.8.7-p299, and DevKit 3.4.5r3-20091110. However this is not a good solution for me for a number of reasons:

1. I’m using Vim 7.3 and would like to continue doing so.
2. Ruby 1.9.3 is installed on my system, and I need it in my PATH for other projects.

So is there any way to get this working, while keeping the latest version of ruby and the latest version of vim?

UPDATE

Having followed AndrewMarshall’s advice, I installed Ruby191 and DevKit-4.5.0-20100819-1536-sfx.exe according to this tutorial and ran ruby extconf.rb through that version. The make cmd executed successfully with this output:

gcc -I. -IC:/Ruby191/include/ruby-1.9.1/i386-mingw32 -I/C/Ruby191/include/ruby-1

and running :CommandT in vim works now, but as soon as I start typing to search for a file, and then hit enter to select and open it, I get this:

Answer 1

not a real answer but you may wanna try ctrlp instead.

• written in vimscript (no dependency, no compiling)
• as fast as CommandT (subjective to me)
• has probably more features than CommandT (does CommandT have most recent file?)

there is also the good old FuzzyFinder which I haven’t tried. seems like it hasn’t got updated for about 2 years but it may still be working.
