Source: lz4 Version: 0.0~r131-1 Tags: patch User: [email protected] Usertags: rebootstrap
Since apt now requires lz4, I looked into cross compiling lz4 and figured that it wouldn't work out of the box. You can find a failing build log at: http://subdivi.de/~helmut/debomatic-logs/lz4_0.0~r131-1_ppc64el.build There are two issues at hand, both of which can be seen in the log above. 1) The build uses the build architecture compiler instead of the cross compiler. Thus the binaries produced are for the wrong architecture and ultimately dh_strip makes the build fail hard. 2) The test suite is run despite being passed DEB_BUILD_OPTIONS=nocheck. Once fixing the first issue, this becomes a hard failure as host architecture executables cannot be run in a typical cross setting. I am attaching a patch that addresses both of these issues. Helmut
