Empty requirement causes install failure about cargo-generate-rpm

[jeking3]

I found I had to set auto-req = "no" and provide my own dependencies to work around this.

@jeking3 as you mentions, workaround is to disable the automatic dependency process with setting auto-req = "no".

If /usr/lib/rpm/find-requires (rpm builtin program) does not exist on your system, cargo-generate-rpm executes ldd and parses its output. So, could you please share the output of ldd release/release/cloudtruth?

I'll close this out because it appears to be working now.

I should mention I run this in the rust:1.52.1-alpine container (to make the RPM), so perhaps that's part of the problem:

On alpine:

bash-5.1$ ldd !$
ldd target/release/cloudtruth
        /lib/ld-musl-x86_64.so.1 (0x7f6ed8af3000)
        libssl.so.1.1 => /lib/libssl.so.1.1 (0x7f6ed8387000)
        libcrypto.so.1.1 => /lib/libcrypto.so.1.1 (0x7f6ed8106000)
        libc.musl-x86_64.so.1 => /lib/ld-musl-x86_64.so.1 (0x7f6ed8af3000)

bash-5.1$ cargo-generate-rpm
/lib/ld-musl-x86_64.so.1: cannot load -v: No such file or directory

Then on centos 8:

[root@a680fea297fb cli]# rpm -q --requires target/generate-rpm/cloudtruth-0.5.4-1.x86_64.rpm
rtld(GNU_HASH)
/bin/sh

[root@92a65b653b44 /]# rpm -i /cli/target/generate-rpm/cloudtruth-0.5.4-1.x86_64.rpm
[root@92a65b653b44 /]# cloudtruth --version
cloudtruth 0.5.4
[root@92a65b653b44 /]#

The -v error is odd, but what's coming out now seems to be working. I tested with v0.4.0 of cargo-generate-rpm.
