make: *** [src/libsam3/libsam3.o] Error 1

[barracuda156]

Some of these are fixable:

1. libsam3.h needs this:

#include <sys/types.h>

This fixes undefined ssize_t.

2. libsam3.c is missing #include <sys/ioctl.h>. See: https://codeberg.org/a-j-wood/pv/issues/74

3. Also in both libsam3.c and libsam3a.c instead of #ifdef __unix__ it should be:

#if defined(__unix__) || defined(__APPLE__)

(I am not sure if __unix__ is defined on Linux; likely these headers are needed on Linux too.)

4. However, <sys/sysinfo.h> is Linux-only header, it should not be used on macOS. I do not have a fix for this.

@eyedeekay @obscuratus Can this be addressed?

[eyedeekay]

Sorry about the delay, I will figure this out when I get back to my office where my Mac is.

[barracuda156]

@eyedeekay Greatly appreciated, thank you.

[obscuratus]

Not really sure why I was mentioned here :)

[barracuda156]

@obscuratus Sorry, feel free to ignore. I just looked who have committed to the source, and tagged to get some attention to the issue, which was open for some months.

[defnax]

any news foe a fix?

[eyedeekay]

any news foe a fix?

I'll get it as soon as I can in the next few days, I'm not normally a Mac user so I'm a shade unfamiliar with the tooling.

[defnax]

no fix yet?

[defnax]

Hi, when comes the fix to master?

[eyedeekay]

As soon as I can get to it, probably sometime around the 19th, I'm pretty swamped with the upcoming release right now and need a little more time.

[barracuda156]

As soon as I can get to it, probably sometime around the 19th, I'm pretty swamped with the upcoming release right now and need a little more time.

Sounds good!

I just back to my PowerPC hardware, and right into the disaster of broken OpenBLAS build and a need to update/fix quite a number of related ports. So will also be busy for coming 3–4 days.
In a positive side, I can now test on all archs from ppc to aarch64.

No surprise here, but just for the record: here is the failure on 10.6 with gcc13:
