Bug 96858 – readline-4.3-r6 fails to build under Mac OSX Tiger

• Product: Gentoo/Alt
• Status: RESOLVED WONTFIX

[Description Douglas Creager 2005-06-23 06:51:48 UTC]

Building readline-4.3-r6 fails under Mac OS X Tiger during the linking phase.  The linking scripts are 
looking for a libcc_dynamic library that does not exist.

Reproducible: Always
Steps to Reproduce:
1.  emerge readline

Actual Results:  
Build failure.  Error message:

/usr/bin/libtool: file: -lcc_dynamic is not an object file (not allowed in a library)


Expected Results:  
Successful build and install.

Under Panther (and possibly earlier versions of OSX), gcc3.3 shipped with libcc_dynamic as a symlink to a 
statically linked libgcc, which was often necessary for certain applications.  For some reason, this is no 
longer needed in the gcc4.0 that is shipped with Tiger.  Including the -lcc_dynamic flag causes links under 
Tiger to fail.  I will post a patch to the ebuild that fixes this problem and installs correctly under Tiger.

Created attachment 61781 [details, diff]
Proposed patch

This patch should create a readline-4.3-r7 ebuild that patches as before when
using <=10.3, and patches without -lcc_dynamic when using 10.4.

I should point out that this libreadline still has a file collision with the pre-installed libreadline, but that is 
independent of this bug.  You'll still need to turn of collision protection to get the qmerge to succeed.

Bug #97243 deals with readline-5*.

I consider this bug out of date, and I think there is no particular interest in
fixing this given there is a newer version out.

Thanks for the report anyway!
