flashrom 1.2 doesn't build on aarch64-linux about flashrom

[dhendrix]

Hello Marek,
Thanks for the report. For what it's worth aarch64 compilation generally works (for example Fedora: https://koji.fedoraproject.org/koji/buildinfo?buildID=1458754).

The issue seems to be with the architecture detection part of the Makefile. I'll take a look into it shortly.

[dhendrix]

@mmahut - The issue seems to be that a compiler macro that indicates target architecture, such as __arm__ or __aarch64__, is not being defined: https://github.com/flashrom/flashrom/blob/master/platform.h#L52

I'd be surprised if this problem is only affecting flashrom compilation. Do you happen to know of other programs that have similar checks for target architecture that you can try compiling in your environment?

Also, can you run gcc -E archtest.c within the flashrom directory and paste the result somewhere? The last line should be a valid architecture. Here is what it looks like on my Raspberry Pi running Debian: https://gist.github.com/dhendrix/3e80d84898ccb57bda29b016eac43d41

Is there an easy way to bootstap a NixOS environment in qemu using a non-NixOS host? I'm trying to follow the docs on nixos.wiki, but much of it seems to assume a NixOS host.

With meson (NixOS/nixpkgs#80293) the failure is different:

I'm being affected by the same issue. Here's some additional notes:

• Trying to build on NixOS, AArch64, on Raspberry Pi 4, in order to get the Raspberry Pi EEPROM update script working.
• I tried an earlier version of flashrom, notably 0.9.7 which seems to be the version the official Raspberry Pi OS packages ( https://github.com/raspberrypi/noobs/blob/master/buildroot/package/flashrom/flashrom.mk ), but it fails also. ( https://github.com/NixOS/nixpkgs/blob/ea49ac04966380be9bc77c62c0d01862b515e6a6/pkgs/tools/misc/flashrom/default.nix )
• The reason why the official Raspberry Pi OS is able to provide a flashrom build is most likely that they don't even target AArch64 but the 32-bit arch, not hitting this problem.

The build system of flashrom doesn't seem familiar to me – is the Makefile hand-crafted or is it generated by something?

[golddranks]

So, some more notes. First of all,

The issue seems to be that a compiler macro that indicates target architecture, such as arm or aarch64, is not being defined: https://github.com/flashrom/flashrom/blob/master/platform.h#L52

This doesn't seem to be true, the macro is defined at least on my system.

Tried building 1.2 with the Makefile (not using meson). It fails here: https://github.com/flashrom/flashrom/blob/1.2.x/Makefile#L1185
... and the reason it fails is because the make variable ARCH contains unexpected contents. I edited the Makefile to print it, it's:

bit outside of fd_set selected arm

What that means, is beyond me.

[golddranks]

An explanation for this value. From here, of the Makefile:

override ARCH := $(strip $(call debug_shell,$(CC) $(CPPFLAGS) -E archtest.c 2>/dev/null | grep -v '^\#' | grep '"' | cut -f 2 -d'"'))

Take cat archtest.log | grep -v '^\#' | grep '"' | cut -f 2 -d'"', where archtest.log is the log pasted earlier in this thread. The result is:

bit outside of fd_set selected
arm

[jtojnar]

Looks like some compiler warning. What do you get if you do not cut it?

[golddranks]

I now have a patch that fixes the problem. I'm trying to figure out how to submit it currently, but the instructions here don't work: https://www.flashrom.org/Development_Guidelines#Using_Github

[golddranks]

Managed to submit it! https://review.coreboot.org/c/flashrom/+/43140 The wiki seemed to have the repo address a bit wrong; not: git remote add -f upstream ssh://<gerrit_username>@review.coreboot.org:29418/flashrom.git. but git remote add -f upstream ssh://<gerrit_username>@review.coreboot.org:29418/flashrom.

[golddranks]

@jtojnar The output parsing script at first strips the lines starting with #, which seem to be preprocessor "stack" annotations; however, after that, it just finds lines with " which seems like a dangerously non-robust parsing method. Here, this line also happens to match: __attribute__((__warning__ ("bit outside of fd_set selected")));, which explains the error.

To me, this seems just an oversight in the output parsing, and the binary built with my patch seems to function fine, but if there's something about the warning that should be taken into account, please inform me. (P.S. as archtest.c is only preprocessed, not compiled, this seems like a harmless thing; not an actual warning, but a thing that would cause a warning if the defined item would be referenced during compilation.)

Thanks for pointing that out, I've fixed the wiki (hopefully).

[golddranks]

Thanks! Btw. about the patch, I'm going to fix it during the following days, hopefully it sticks.

[golddranks]

https://review.coreboot.org/c/flashrom/+/43140 Sorry, no luck yet. It's been reviewed a long time ago, but nobody seems to go and merge it...

[golddranks]

My PR was merged, so this will be fixed eventually. No idea when the next release is, though.
