Dear diffutils developers,
I am currently building Linux From Scratch and cross-compiling temporary tools.
When compiling diffutils-3.12 with the following script:
./configure --prefix=/usr \
--host=$LFS_TGT \
gl_cv_func_strcasecmp_works=y \
--build=$(./build-aux/config.guess) \
&& make -j$(nproc) \
&& make DESTDIR=$LFS install
I encounter these errors during make:
help2man: can't get `--help' info from sdiff
Try `--no-discard-stderr' if option outputs to stderr
help2man: can't get `--help' info from cmp
Try `--no-discard-stderr' if option outputs to stderr
help2man: can't get `--help' info from diff
Try `--no-discard-stderr' if option outputs to stderr
make[1]: *** [Makefile:2574: sdiff.1] Error 1
make[1]: *** Waiting for unfinished jobs....
make[1]: *** [Makefile:2574: cmp.1] Error 1
make[1]: *** [Makefile:2574: diff.1] Error 1
make[1]: Leaving directory '/mnt/lfs/sources/diffutils-3.12/man'
make: *** [Makefile:2437: all-recursive] Error 1
My host system is Ubuntu 22.04 with gcc 11.4.0. According to the Linux From
Scratch book, this problem should not occur, so I am unsure why it happens on
my system.
I have tried several methods to bypass or fix this issue, including:
make HELP2MAN=: or make HELP2MAN=true
Running make with HELP2MAN="help2man --no-discard-stderr"
Exporting HELP2MAN=: or make HELP2MAN=true shell environment
None of these attempts resolved the problem.
Could you please advise:
Why this problem might be occurring in my environment?
What is the recommended way to bypass or fix the help2man step during the build?
Thank you very much for your time and assistance.
Best regards,
