James E. King, III updated THRIFT-4109:
---------------------------------------
Component/s: Java - Library
Build Process
> Configure Script uses string comparison for versions
> ----------------------------------------------------
>
> Key: THRIFT-4109
> URL: https://issues.apache.org/jira/browse/THRIFT-4109
> Project: Thrift
> Issue Type: Bug
> Components: Build Process, Java - Library
> Reporter: Devin Avery
> Fix For: 0.9.3, 0.10.0
>
>
> I am running the configure script as outlined here for MAC OSx -
> http://thrift.apache.org/docs/install/os_x
> I found that the configure script is doing string based comparison for
> performing version verification which breaks as soon as a version changes
> from one digit to two. For example, homebrew installs ant version 1.10.x now
> (as of March 7th, 2017) which is clearly greater than 1.7 which thrift
> requires. However the thrift configure script fails to detect ant because it
> thinks the version is wrong.
> This is because this line in the configure script (around line 18844 in
> version 0.9.3) -
> {code}
> ANT_VALID=expr $($ANT -version 2>/dev/null | sed -n 's/.*version
> \([0-9\.]*\).*/\1/p') \>= 1.7`
> {code}
> Notice how you are using the >= which is STRING comparison, not version
> comparison. When 1.10.1 compares to 1.7 it is considered LESS than instead
> of greater than.
