[ruby-core:40839] [ruby-trunk - Bug #5532] Compile problem for bigdecimal on cygwin

Issue #5532 has been updated by Heesob Park.


Hi,

I noticed that the problem started when you executed "cd /cygdrive/c/Data/Ruby" 
instead of "cd /cygdrive/c/Data/ruby".

Here is the test case.

$ mkdir -p /cygdrive/c/Data/ruby
$ cd /cygdrive/c/Data/Ruby

phasis@phasis-PC /cygdrive/c/Data/Ruby
$ irb
irb(main):001:0> Dir.pwd
=> "/cygdrive/c/Data/Ruby"
irb(main):002:0> File.expand_path("./test.txt")
=> "/cygdrive/c/Data/Ruby/test.txt"
irb(main):003:0> exit

phasis@phasis-PC /cygdrive/c/Data/Ruby
$ cd /cygdrive/c/Data/ruby

phasis@phasis-PC /cygdrive/c/Data/ruby
$ irb
irb(main):001:0> Dir.pwd
=> "/cygdrive/c/Data/ruby"
irb(main):002:0> File.expand_path("./test.txt")
=> "/cygdrive/c/Data/ruby/test.txt"
irb(main):003:0> exit

Notice the diffrence between "/cygdrive/c/Data/Ruby/test.txt"
and "/cygdrive/c/Data/ruby/test.txt".

Park Heesob

I tried to complile the current trunk on cygwin. However, I got a compile problem in 'bigdecimal'.
It says (see below for full output):

>>>>>>>>
configuring bigdecimal
checking for labs() in stdlib.h... /cygdrive/c/Data/ruby/lib/mkmf.rb:381:in `try_do': The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.
>>>>>>>>

What kinds of development tools would be needed? I have successfully compiled Ruby many times; this is the first time I have been told I need 'development tools'.

Many thanks for your help,     Martin.

Full output follows:
