Unable to compile c program on trident stable

[fekir]

Describe the bug
I'm unable to compile a simple c test program in trident, neither with clang, nor with gcc.

To Reproduce
Install trident.
Optionally install gcc or other clang versions
Compile a simple program
See error on stderr

Expected behavior
No error in stderr, and a working executable as output from the compiler.

OS Version:

FreeBSD trident-7822 12.0-STABLE FreeBSD 12.0-STABLE GENERIC  amd64

Additional context
Hello,

I've played a little bit with trident, I'm sorry if I'm reporting this bug (or at least inconsistent behavior for which I found no documentation)

I've installed trident from the dvd, and after it different packages for developing in c++ and c, like clang, gcc, cppcheck and so on.

Unfortunately I'm not able to compile even a simple test program.

As I'm new to the bsd world, I thought I would have misconfigured something.
So I've retested on naked system (just installation, tested before and after updating the system, no additional development packages installed)

I believe this is a bug, If a compiler is present, it should also work.
If it is not intended to work, then maybe it should not be there, and installing a compiler should install as dependency all libraries for compiling a minimal program.

What should I install for being able to compile c and c++ programs?
I could not find any package containing libc_nonshared and libssp_nonshared, those libraries do not seem to be present on trident, but are on freebsd.

Notice that on a minimal freebsd system cc was avaiable (it was on none of the tested trident systems) and I could build main.c without issues and without installing additional packages.

The C program is simply:

> cat main.c
int main(void) {
        return 0;
}

You simply need to install the "os-generic-userland-devtools" package to get the entire compiler toolchain installed and setup.

@beanpole135

thank you, installing the os-generic-userland-devtools package fixed the issue, and also created cc.

Might I ask how one should have diagnosed the problem in order to understand what package he needed to install?
I was not able to find any hint, and my experience with BSD systems is limited.

Also does it make sense for trident to have some program with broken dependencies installed by default?
AFAIK the compiler is not usable, wouldn't it be better not having it at all?
