Compilation failed in Linux

SDK Questions sdk-c
1

Hello,

As per the title, compiling the C-SDK in Linux failed (ArchLinux, kernel 5.15.24-1-lts x86_64).

I also tried with cmake --build . but got the same result.

You can find the trace below. Thanks!

Out of curiosity, are you on the latest main branch and have you issued a pull lately? Also, what version of GCC do you have?

I just tried it myself in a clean ubuntu image and also had a compilation error but for me it was just past where you were. Mine ended up failing on the newest stuff added recently which is just past where yours failed.

I have:

gcc --version
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

Failure for me below (but not relevant to you yet)

Yes and yesterday.

gcc --version
gcc (GCC) 11.2.0

it appears that the version of mbedTLS we are using by default is not supporting gcc-11 yet

on option – maybe even preferred, depending on your circumstances – is to use OpenSSL instead.
to use OpenSSL specify -DUSE_OPENSSL=on to your cmake configuration step

5

you need to apt install zlib1g-dev to get that header

6

Can you guide to me which file to edit and with what please?

7

not a file.

When you run CMake the first time, you’d add that option, something like this (in your build directory):

$ cmake -G Ninja -DUSE_OPENSSL=on <path to source>

I did as asked, got a different error on a fresh build: #( 02/18/22@ 5:08PM )( fernando@animal ):~/Documents/vortex/ziti/ziti-sdk-c/buil - Pastebin.com

Hi and thanks for getting back to us. We’ve been using older gcc versions in our linux build systems so you are finding a few bumps related to the newer compiler version. Can you try a clean build from a branch that pulls in gcc11-compatible dependencies - GitHub - openziti/ziti-sdk-c at uv-mbed.13.10 ?

Hi @falves, fyi the branch that I mentioned in my previous no longer exists, because it has been merged to main. Please pull the changes and let us know how it goes!

It was built successfully. Many thanks!

Now that it was built, any suggestions on how to use it? I see no install or use instructions.

The primary artifact of the ziti-sdk-c project is a library that you can use to connect your own c/c++ applications over a ziti network.

Have a look at Overview | Ziti for some background on what a ziti network is and how to set one up.

You can install the ziti library and its includes with cmake:

$ cmake --install . --prefix /wherever/you/want

Then you can #include "ziti/ziti.h" in your application and use the Ziti API to initiate or accept connections. The best documentation that we currently have for using the ziti-sdk-c is the sample applications at ziti-sdk-c/programs at main · openziti/ziti-sdk-c · GitHub. Most of these applications are simple clients that connect to a ziti service. sample-host is an example of a server application (that accepts connections from ziti clients).

Finally ziti-prox-c is a simple proxy that makes it possible for existing tcp/ip client apps to connect through a ziti network.

Given the output of cmake --install:

.
|-- include
|   |-- uv
|   |-- uv.h
|   |-- uv_mbed
|   `-- ziti
|-- lib
|   |-- libuv.so -> libuv.so.1
|   |-- libuv.so.1 -> libuv.so.1.0.0
|   |-- libuv.so.1.0.0

|   |-- libuv_mbed.a
|   |-- libziti.a
|   |-- libziti.so
|   `-- pkgconfig
`-- share
    `-- doc

I assume the intended install point is /usr so as to use the ziti libs as any other system lib:

$ cmake --install . --prefix /usr

I installed in /usr as I mentioned in the previous post, and I got this output compiling one of your git examples:

You just need to tell the linker about libziti.so:

$ gcc -I /home/scarey/ziti-install/include -L /home/scarey/ziti-install/lib64 sample-host.c -l ziti

Pointing to the lib worked, but shouldn’t that be handled by the include statements?

Some compilers do support so-called auto-linking, where the linked libraries can be specified by pragmas in the include files. To my knowledge gcc does not support this.
