Dear all,

when I install rb-gsl in cygwin using the ruby setup.rb config command,  
I get many repeating errors, each of the following form:

78678783 [main] ruby 2536 C:\cygwin\usr\local\bin\ruby.exe : \*\*\* fatal  
error: unable to remap  
C:\cygwin\usr\local\lib\ruby\1.8\i-386-cygwin\[etc.so](http://etc.so) to same address as  
parent  
(0x2830000) != 0x2840000  
65108726 [main] ruby 1440: child\_copy: loaded dll child copy failed  
0x28330000...0x2833170, done 0, windows pid 5468565, Win32 error 5.

These lines keep returning, with some differences in the windows pid numbers  
and in the  
numbers before [main].

What is going on here? What could be done to fix it ?

Thank you very much!

Best regards,

Axel

i think you've got more than one ruby on your system and/or have upgraded ruby  
or ruby extensions in a way that was not correct.

in any case, this is purely a cygwin issue. sorry i can't help more.
