Subject: [ruby-core:40837] [ruby-trunk - Bug #5532][Closed] Compile problem for bigdecimal on cygwin


Issue #5532 has been updated by Martin D��rst.

Status changed from Open to Closed

Hello Heesob,

Many thanks for solving this problem. You are right that it is about case differences in the path name. However, your description might be slightly misunderstood. The problem is not upper-case letters per se, but letters for which case differs from how they are stored by the OS. In my case /cygdrive/c/Data/ruby/ is correct, because Data is indeed upper-case (Windows remembers the case of a letter, but matches upper- and lowercase).

Regards,    Martin.

(I'm still not able to compile completely, but I'll try to get further and open another bug if necessary.)

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:
