Hello,<br>
<br>
I have an idea to improve the CMake build system by integrating with
the abi-compliance-checker [1] tool. It's a tool for checking for
API/ABI backward compatibility of C/C++ libraries. In the Java world
there is an alternative tool called Clirr, which is already
integrated to the Ant and Maven build systems as a plug-in. But
there is no such thing in the C/C++ world yet. So, people have to
create custom scripts (phonon/cmake [2], mysql++/make [3], ...) to
integrate the abi-compliance-checker tool into the build system.
<br>
<br>
It would be great if CMake users could be able to check API/ABI
changes using two easy built-in CMake commands: "make abidump" and
"make abicheck", without the need to understand how the
abi-compliance-checker tool works. The first command ("make
abidump") should create a snapshot of a "stable" library ABI, which
will be compared with the next releases by the second command ("make
abicheck"):
<br>
<br>
"make abidump": abi-compliance-checker --lib=name --dump=v1.xml
--dump-path=snapshot-v1.abi.tar.gz
<br>
"make abicheck": abi-compliance-checker --lib=name
--d1=snapshot-v1.abi.tar.gz --d2=v2.xml
<br>
<br>
v1.xml and v2.xml are XML-descriptors of old (snapshot) and new
(current) versions of a library(ies):
<br>
<br>
<version>
<br>
1.0
<br>
</version>
<br>
<br>
<headers>
<br>
<i class="moz-txt-slash"><span class="moz-txt-tag">/</span>directory/with/headers<span
class="moz-txt-tag">/</span></i>
<br>
</headers>
<br>
<br>
<libs>
<br>
<i class="moz-txt-slash"><span class="moz-txt-tag">/</span>directory/with/libraries<span
class="moz-txt-tag">/</span></i>
<br>
</libs>
<br>
<br>
I'm not familiar with the CMake internals and cannot implement this
feature by myself. It would be great if some experts in CMake could
write it. Considering the great number of C/C++ libraries using
CMake, this feature should make upstream development of C/C++
libraries more stable.<br>
<br>
Thanks!
