Build linux wvunpack without rpaths
Last modified: 2007-11-05 06:52:27 UTC
Is it possible to build the linux wvunpack without using rpaths? The Red Hat rpmbuild tools don't like this and it complicates the spec file and the build system. See http://fedoraproject.org/wiki/Packaging/Guidelines#head-a1dfb5f46bf4098841e31a75d833e6e1b3e72544 for more information. For reference, output from rpmbuild is: + /usr/lib/rpm/check-rpaths /usr/lib/rpm/check-buildroot ******************************************************************************* * * WARNING: 'check-rpaths' detected a broken RPATH and will cause 'rpmbuild' * to fail.

andy, what say you?
Created attachment 2356 [details] Binary without rpath Well you learn something new every day, I had never heard of rpath before. :) I rebuilt with --disable-rpath but the linker command was still run like this: gcc -g -O2 -o .libs/wvunpack wvunpack-wvunpack.o wvunpack-utils.o wvunpack-md5.o ../src/.libs/libwavpack.a -lm -Wl,--rpath -Wl,/usr/local/lib (I modified it to statically link in libwavpack.a instead of use libwavpack.so). I re-linked using: gcc -g -O2 -o .libs/wvunpack wvunpack-wvunpack.o wvunpack-utils.o wvunpack-md5.o ../src/.libs/libwavpack.a -lm -Wl -Wl The output of ldd is the same in each case so I'm not sure how to test. Can you check the attached binary and see if it's OK?
The attached binary solves the problem. Thanks.
