[package] doxygen/*: cannot install directly because of revision hashes in dependency versions

[tkhyn]

Description

Hi,

I have an issue conan-installing doxygen binaries. I think I understand what is happening, but I don't know how to solve this.

The problem seems to come from the fact that doxygen has revision hashes in its dependencies versions, and forces a rebuild while it should in theory just download the binary from conan-center.

When running conan install --tool-requires=doxygen/1.12.0@ using a fresh new conan home leads to:

...
ERROR: Missing binary: doxygen/1.12.0:08f15a63d34e3ca2a8a311ff2f7d8b2b11b7c2a4
...

conan graph explain --tool-requires=doxygen/1.12.0@ gives:

        explanation: This binary has same settings and options, but different dependencie

Whereas, if I clean up the conan home and I manually run:

conan install --tool-requires=libiconv/1.17@#73fefc1b696e069df90fd1d18aa63edd
conan install --tool-requires=zlib/1.3.1@#f52e03ae3d251dec704634230cd806a2
conan install --tool-requires=doxygen/1.12.0@

Then everything works.

So my question is: how can we make the expected behaviour (i.e. conan install --tool-requires=doxygen/1.12.0@ completes properly straight away)?

Is the fact that the doxygen recipe references dependency revisions in its requirements while conan ignores them and always installs the latest revision? In that case shouldn't these dependency revisions be removed from the doxygen recipe dependencies? If yes, how can we do that? I don't see anything in the recipe that would explain why the revisions are part of the dependency versions and all the other recipes I have looked at do not have them ...
