[Win32utils-devel] Possible problem with msvcrt vs msvcrXX
Hi,
I tried this with a version of Ruby I built with VC++ 2008:
irb(main):005:0> strlen = API.new(''strlen'',
''P'', ''L'', ''msvcrt'')
=> #<Win32::API:0x4774684>
irb(main):006:0> strlen = API.new(''strlen'',
''P'', ''L'', ''msvcr90'')
Win32::API::LoadLibraryError: LoadLibrary() function failed for
''msvcr90'':
The specified module could not be found.
from (irb):6:in `initialize''
from (irb):6:in `new''
from (irb):6
Do I have an environment issue? Do we need to revisit windows-api with
regards to how it sets MSVCRT_DLL?
Regards,
Dan

Create ''ruby.exe.manifest'' in the ruby''s bin folder like this: mt -inputresource:ruby.exe;2 -out:ruby.exe.manifest Regards, Park Heesob

Did you build ruby with non default compiler option? Both ruby.exe and msvcr90-ruby18.dll have dependency with msvcr90.dll. You can check with "dumpbin /imports ruby.exe" If you have a path issue, ruby.exe and irb should failed to run. Regards, Park Heesob
