Linuxbrew-core: coreutils: help2man: can't get `--help' info from man/chcon.td/chcon

[LordRust]

Fresh standard (not stand alone) install of linuxbrew on RHEL 7. Brew doctor have no complaints.

Seems to fail in the manual generation when brewing stable coreutils 8.25. Tried with help2man via both yum and brew.

I haven't run into this error yet myself. Interesting. One workaround that may work is to use a precompiled binary bottle. Try brew install --force-bottle coreutils

[LordRust]

--force-bottle works in the limited testing I did now, thanks :) Do all/most packages also have prebuilt binaries?
coreutils builds fine in another test I did with a standalone linuxbrew install

[rwhogg]

Do all/most packages also have prebuilt binaries?

269 out of 3613 "core" formulae have bottles, including most of the popular ones, and some others (a lot of the Java-based formulae, for example) don't need them. We're working on the rest :smile_cat:

[sjackman]

I'm glad that the workaround worked. The error is a mystery to me though. I'm going to leave this issue open, in the hopes that someone offers some insight.

I found a hit on Google for it: http://lists.linuxfromscratch.org/pipermail/lfs-support/2014-November/048100.html
My best guess is that it's a Makefile race condition and it may be resolved by:

HOMEBREW_MAKE_JOBS=1 brew install coreutils

[LordRust]

HOMEBREW_MAKE_JOBS=1 brew install coreutils

Tried to set the variable, but unfortunately the brew fails on the same step, so it might not be a race condition.

[sjackman]

Sorry I couldn't be of more help.

Similar issue on coreutils install. The binary bottle installed but gives Illegal Instruction on many of the commands like rm and mkdir

$ brew install coreutils

@dwaggott Please report the output of brew gist-logs coreutils

Illegal Instruction

Which processor (CPU) are you using?

[sjackman]

brew config reports CPU: 32-core 64-bit haswell. I can't think of any good reason that you should be seeing Illegal Instruction. Try getting a backtrace from gdb of the core dump.

ulimit -c unlimited
mkdir foo
# illegal instruction, core dumped
gdb mkdir core.*
bt
x/i $pc
quit

[sjackman]

As for help2man: can't get '--help' info from man/cp.td/cp, I'd suggesting reporting the bug upstream to the coreutils developers.

[iMichka]

This issue is almost 1 year old. Since then, corutils has been bumped to version 8.28. I am closing this issue; if you still have trouble with this, please open a new issue and fill out the issue template. Thanks/

[JuPlutonic]

Brew install --force-bottle coreutils is the remedy for me now.
I will test it with my home PCs and see if it reproducable...

[sjackman]

I've just run into this particular error myself.

  GEN      man/chcon.1
help2man: can't get `--help' info from man/chcon.td/chcon
Try `--no-discard-stderr' if option outputs to stderr
make[2]: *** [man/chcon.1] Error 127

A workaround is brew install --force-bottle coreutils
