Subject: Re: [dpdk-dev] [PATCH v3 6/6] mk: prevent overlinking in applications
Date: Mon, 13 Jun 2016 11:24:00 +0200 [thread overview]
Message-ID: <CAATJJ0K5PLibRiR3+-ZZSjZozipiKPTGk9wufP48vX0ma_CsKA@mail.gmail.com> (raw)

Hi,
great work on cleaning that up already.
I applied v3 of the series and see already much better results.
But I found some more that should be part of this.
I don't know how generally available a similar solution is, but usually in
our build dpkg-shlibdeps checks for under/overlinking issues.
I let that run on a dir built from git plus v3 of the series in discussion
here.
There are two way of open dependency issues left:
1. some libraries use symbols of other libraries they are not linked with
correctly yet
2. the appliactions are still overlinking
We need to finalize #1 first before being able to tackle #2 without
breaking something.
I'll send a patch for the following so it can be part of your v4
$ for binfile in $(find debian/build/shared-root/lib -executable -type f;
find debian/build/shared-root/app -executable -type f;); do printf
"\n\n\nTesting %s\n" $binfile; dpkg-shlibdeps -e $binfile
-ldebian/build/shared-root/lib/ | grep -v "installed in their package's
directory"; done
