Why do you think the documentation has to be specific for FreeBSD?
This seems appropriate: https://www.open62541.org/doc/1.3/tutorial_server_firststeps.html
In the link you sent me there is a section that describes how to build open62541 for OpenBSD
There is nothing you need to build,
pkg install open62541 will install everything already.
pkg install open62541$ gcc -std=c99 open62541.c myServer.c -o myServer
but leaving out the [B]myServer.c [/B]file because I don't where to find it or generate it
[B] [aperri@freebsd ~/open62541Learning]$ gcc -std=c99 myServer.c -o myServer [/B]
In compiling it the compiler spews out the following information
[aperri@freebsd ~/open62541Learning]$ gcc -std=c99 myServer.c -o myServer

SirDice, thank you for trying to get me straight in how to start leaning about open62541, but I'm still groping in the dark. In the link you sent to compile the myServer.c example listed there assume that I have the open62541.c/.h files in the same folder I have myServer.c in. For not knowing any better I downloaded these files from the following link https://github.com/open62541/open62541/releases/tag/v1.3.6 to determine how to build my own "myServer.c" file based on the (/usr/local/include/ and /usr/local/lib/) on my computer after installing the open62541 pkg. I'm running in circles regarding this endeavor. Could you help me out with this please. I've attached the beginnings of myServer.c file showing my attempt so far.
I suspect those open62541.c/.h files are not properly patched for FreeBSD...
% mkdir open62541
% cd open62541
% (fetch open62541.c/.h files in the same folder I have myServer.c in )
% gcc -std=c99 open62541.c myServer.c -o myServer
% (Got compilation errors, mostly related to networking)You started this thread asking for help compiling something and that’s what has been provided.
Seems like the compiler line that you got from the instructions (linked to by SirDice ) wants those files to be in the same directory as myServer.c... When I installed the open62541 port, I ran
updatedb as root. (On FreeBSD, it's a symlink to /usr/libexec/locate.updatedb that you have to make yourself). Doing it as root picks up ALL files on the system, so there are reasons to avoid running it as root. updatedb as root, you should be able to use locate to find the files in question. In my case, I discovered that the usual locations (/usr/local/include/ and /usr/local/lib/ ) actually don't have the open62541.c/.h files... Not only that, they were not present on the system at all, which is why I had to download them. make look in the standard locations, or your can modify the include lines in myServer.c to look in the standard locations (provided the standard locations actually have the open62541.c/.h files that are needed). Or you can just go along with instructions and have those files in the same directory as myServer.c...The open62541.c/.h that you downloaded are a subset of the open62541 pkg files you install for FreeBSD.
If that were the case,
locate would find those files (provided you ran updatedb beforehand). And yeah, presence of actual files is important to pay attention to when compiling, no matter the platform. Sometimes, though, an OS-specific package is not very well crafted, and trying to install it, one discovers that there are parts missing. Unfortunate, but to be expected when dealing with Open Source software.The file open62541.h or the open62541.c does NOT 'contain' header files. It will have
# include lines that refer to those files. Yes, there is a difference, and it is important to pay attention to it when compiling anything.$ locate config.h | grep 62541

I find what that tutorial asks you to do to be really confusing. On the one hand they instruct you to download the "amalgamated" release file (open62541.c), but also mention that you'll wind up with the open62541.h file in your work directory.
