I'm not sure of anything. Putting together a few facts makes me suspicious.
First, PM crash.
Second, glamor not usable.
Third, glx compat mode.
It is easy in the LFS to get something slightly wrong, some --enable-something missing somewhere maybe.
Then again, if you feel happy and everything works for you, why worry.

I'm not happy! I have a browser that works and that's fine. But I also like to understand what I'm doing and right now I feel that I don't. I can't build PM on this system because of the compiler problem, but importing it from another system sometimes works and sometimes doesn't. That's illogical.

You still haven't explained what "compat" means and why it's bad.

I think the next step is to uninstall the xf86 intel driver, which seems to cause more trouble than it's worth, and rebuild mesa with the swrast gallium driver as well as the i915 one. Maybe that will make the system better behaved.

I haven't explained what compat mode is ... because I don't know! It just seems suspicious to me, makes me think the software has no proper support for this particular hardware. Do you have any reliable source supporting your gallium build? All comparisons I have found gallium vs. classic on Intel claim gallium is way inferior.

Here is the BLFS page for building mesa. I followed it blindly because I don't know enough about graphics to diverge from it. Usually with LFS, just following the book is good enough. I've built several LFS systems like that, using each in turn as the build host for the next one.

The problem is that, for the first time ever, I am using a browser that is not in the book. I don't know if Pale Moon has ever been tried out in an LFS environment. And seemingly it has problems. I'd like to see if I can fix them, that's all.

I wonder if you run a well designed live Linux live CD/DVD, what will be loaded for your Intel Q33. What will glxinfo show, what's in Xorg log, etc. I've been running Gentoo since 2004, I find running SystemRescueCD can be extremely useful figuring out how to configure a new system.

Intel and Gallium, searching and finding only bad news about Intel and Gallium.

Got it! I rebuilt mesa with the svga and software rasteriser in place. Now the Pale Moon that I built in LFS-8.0 runs in LFS-8.1 and I can log into Yahoo with it too. And glxinfo looks quite different:
Code:
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: VMware, Inc. (0xffffffff)
    Device: llvmpipe (LLVM 4.0, 128 bits) (0xffffffff)
    Version: 17.1.6
    Accelerated: no
    Video memory: 1995MB
    Unified memory: no
    Preferred profile: core (0x1)
    Max core profile version: 3.3
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.0
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 128 bits)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.1.6
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

Cool! So our suspicions about rendering problems got confirmed after all.

Yup! You nailed it. But unlike you, I don't see anything sinister in the inability to use glamor. Remember, this is old hardware. According to the Gentoo wiki, it's only third generation, and we're supposed to be on ninth gen now. That message about an insufficient instruction set sounds like inadequate hardware to me.

The other problem which I can't deal with is the inability to build Pale Moon with gcc-7. At the moment, that doesn't matter because I have two systems that use gcc-6. It will become a problem in the future, but for the PM devs to solve, not me. Perhaps they are already onto it.

Hey! Look what I just found!

Well, reading up on Gallium and Intel. It appears Intel never supported Gallium and supported MESA Classic only with their driver. Since the driver is open source some enthusiasts started working on Gallium, porting it for Intel, but their work never reached a state where Gallium on Intel would perform even close to Classic. Thus, I personally do not consider Gallium with Intel driver as a viable option. Indeed, this is a free world and in no way I'm telling you how to configure your computer.

You have a nice day now. Some people in these forums are making me sad, needless to say, nobody wants to be sad, it is only natural to avoid the source of sadness. Logging off. Will be back one day, I guess.
