explicit the dependency from libc-ares library
hariseldon78 opened this issue · 6 comments
i found i was missing this library to complete the build. i installed it on ubuntu with the package libc-ares-dev
Before 1.1.0 IoTA was not built in ubuntu. In branch develop you can see a third_party directory with some tools needed to build (and only for this purpose). In this branch, additional software is downloaded (you can see CMakeLists.txt file to check versions we use). c-ares are included (as well as mosquitto).
Any question or problems, we will try fix it.
hello again. i'm trying to run the iotagent on ubuntu, but he has problems seeing the libssl and libcrypto libraries. he searches them with the ".so.10" suffix, and ubuntu has the ".so.1.0.0" instead. I made the 2 symbolic links but at that point i get this error:
...$ /usr/local/iot/bin/iotagent --help
/usr/local/iot/bin/iotagent: /lib/x86_64-linux-gnu/libssl.so.10: version `libssl.so.10' not found (required by /usr/local/iot/bin/iotagent)
/usr/local/iot/bin/iotagent: /lib/x86_64-linux-gnu/libcrypto.so.10: version `libcrypto.so.10' not found (required by /usr/local/iot/bin/iotagent)
/usr/local/iot/bin/iotagent: /lib/x86_64-linux-gnu/libcrypto.so.10: version `libcrypto.so.10' not found (required by /usr/local/iot/lib/libpion-5.0.so)

We are testing this problem. At this moment, I think the problem may be some libraries (pion, for example) are built referencing a library version. We are building in ubuntu: (ldd over iotagent executable)
libssl.so.1.0.0 => /lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007fe472eb7000)
libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007fe472adc000)
and no problem at starting iotagent.
Library version is "annotated" in building process. One question could be if you starting iotagent in same host where you are building iotagent (or with same libraries).??
(We are in develop branch)
i ran iotagent on the same machine where i built it; though i built it
before creating the symlinks to the "10 to 1.0.0" symlinks. my ubuntu
release is the 14.04.2 LTS (GNU/Linux 3.13.0-24-generic x86_64)

Hello,
I was searching for a reason. I use Ubuntu 14.04 3.16.0-36 and I have not this problem (I don’t know who is searching for so.10).
Agustin.

I follow with this problem. But, sorry, I dont understand: if you build from sources on a host with .so.10 (all dependencies are built in this host) and you start iotagent on THIS host, iotagent and pion search for .so.1.0.0. Is that what happen (or viceversa, host with .so.1.0.0 search for .so.10)?
