Subject: [ruby-core:47618] [ruby-trunk - Bug #7036] Compiling extensions with Ruby in a path with spaces


Issue #7036 has been updated by luislavena (Luis Lavena).

File disable-libpathflag-mingw.v2.diff added

Nobu,

Looking at some of the changes you did couldn't understand entirely, but understood that $extmk gets set only when building from extmk.rb, which gave me the idea of the new patch I'm attaching.

This new patch set LIBPATHFLAG as empty allowing -L"%s" from mkmf to work.

It also quotes $ruby unless running in $extmk mode.

This new patch works for both compilation of Ruby stdlib extensions and after installation, to compile extensions from gems on path with spaces.

I know is very (very) naive approach, so will appreciate your feedback.

Thank you.

Hello,

This has been reported several times to RubyInstaller: inability to install gems when Ruby has been installed in a path with spaces (e.g. (({C:\Program Files})))

Since this is presented to the user as (({gem install})) error, a deeper investigation revealed:

Generated Makefile contains a reference to (({RUBY})) that is not quoted, resulting in errors like this:

 V:\User Name\ruby-2.0.0dev-i386-mingw32\lib\ruby\gems\2.0.0\gems\json-1.7.5\ext\json\ext\generator>make
 generating generator-i386-mingw32.def
 /bin/sh: V:/User: No such file or directory
 make: *** [generator-i386-mingw32.def] Error 127

This can be easily solved by doing:

 ruby = #{$ruby.quote}

The second issue is more complicated, as is caused by (({$LIBPATH})) and (({libdir})):

 linking shared-object json/ext/generator.so
 gcc.exe: error: Name/ruby-2.0.0dev-i386-mingw32/lib: No such file or directory
 make: *** [generator.so] Error 1

While (({LIBPATH})) is being built using (({libpathflag})) method, this method fails to detect path with spaces since it uses (({LIBPATHFLAG})) from rbconfig

Since mkmf finds the above mentioned key in (({RbConfig::CONFIG})), it never attempts to use -L"%s" alternative:

  LIBPATHFLAG = config_string('LIBPATHFLAG') || ' -L"%s"'

Now, (({libpathflag})) do not detect a path with spaces because the array of options given are (({[".", "$(libdir)"]})).

In the case of Windows, LIBPATHFLAG shouldn't be hardcoded, or at least should always quote strings, considering Ruby can be relocated.

Nobu, Usa, Hiroshi, what are your thoughts about this?

I'm looking for some feedback before I start some modifications.

Thank you in advance for your time.
