Hello,
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.
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"):
"make abidump": abi-compliance-checker --lib=name --dump=v1.xml
--dump-path=snapshot-v1.abi.tar.gz
"make abicheck": abi-compliance-checker --lib=name
--d1=snapshot-v1.abi.tar.gz --d2=v2.xml
v1.xml and v2.xml are XML-descriptors of old (snapshot) and new
(current) versions of a library(ies):
<version>
1.0
</version>
<headers>
/directory/with/headers/
</headers>
<libs>
/directory/with/libraries/
</libs>
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.
Maybe you don't have to be familiar with CMake internals to do this.
It may be that this can be done simply in cmake script, but putting some
macros or functions into a CMakeABICheck.cmake file or something like this.
Did you try to use add_custom_target() to exeucte the described steps ?
Alex
I will follow this way. Thanks!
