fgrep fails to find grep during bootstrap

fgrep fails to find grep during bootstrap

[Carlos Sánchez de La Lama]

Hi all,

I am trying to bootstrap for powerpc-linux. I have generated the
tarballs and patched gnu/packages/bootstrap.scm to use them.

However, I get an error during when creating %bootstrap-coreutils&co
package. It specifies "fgrep" as program to test, but fgrep is a shell
script, and altought the shebang is correctly patched, it needs "grep"
binary in the path (which is not at this stage). fgrep does:

exec grep -F "$@"

so this can not work unless grep is available in PATH.

Options would be to patch those scripts to use `dirname $0`/grep, or
just test another program in package-from-tarball (the program testes
used to be "true"). I am doing the latter to go on bootstraping.

BR

Carlos

I thought it was just me! I've been looking at that test error for a
while with my aarch64 machine(s) and trying to figure out what to do
with it.

have you tried it with reverting commit 84cbe39c5a21495647ab6528715c42e4c5b94e83 ?

I've fixed this problem on the core-updates branch:

http://git.savannah.gnu.org/cgit/guix.git/commit/?h=core-updates&id=1063d325ea76aa2b00dfcd3d436b16e412103df1

Kind of; I changed program to test to "true" (like it was before the
commit) but I did not remove the shebang patching, which was being
correctly done and did not harm. That allowed me to go on (and hit the
next problem some minutes later ;) )

Anyways, Mark has fixed it already.
