Problem with stdint

Hi,

I have a problem with stdint types in deployer. Natively OROCOS doesn't support these types, there are only registered aliases for uint32 and int32. I have found stdint typekit on OROCOS github (https://github.com/orocos-toolchain/stdint_typekit) but I have following problem, after typing import("stdint") in deployer, process crash witch message

12.187 [ Warning][TypekitRepository::Import] RTT type repository already knows type 'int32' as type 'int'. Aliasing type 'int'
12.187 [ Warning][TypekitRepository::Import] RTT type repository already knows type 'uint32' as type 'uint'. Aliasing type 'uint'
Segmentation fault (core dumped)

Has anyone met this problem before? My setup is following: Ubuntu 12.04, ROS Hydro, OROCOS 2.8 (from git) build with catkin.

Best,
Mariusz

Problem with stdint

Hi Mariusz,

I could reproduce this issue with a similar setup. It looks like the last
commit (
https://github.com/orocos-toolchain/stdint_typekit/commit/b6d48396c7e327...)
is responsible for the segfault, as the type name int32 is not registered
as an alias of int anymore and ti->type("int32") in StdintTypekit.cpp:146
<https://github.com/orocos-toolchain/stdint_typekit/blob/master/StdintTypekit.cpp#L146>
returns
a zero pointer.

I created a pull request here:
https://github.com/orocos-toolchain/stdint_typekit/pull/1

Even if not related to the reported problem it should be noted that the
stdint_typekit package is neither a rosbuild (missing Makefile) nor a
catkin package (no package.xml). The pull request adds support for both by
adding the two files. It should not influence pure cmake builds.

Best,
Johannes

I have fetched your commits and unfortunately I still get segmentation fault.

I know, I was able to handle this issue.
