Hints on how to quickly install `rapidjson` on those distributions that don't feature it

[cipriancraciun]

I've tried to build laminar on OpenSUSE Tumbleweed (i.e. the "rolling" release of OpenSUSE, with all the latest packages), and unfortunately there is no rapidjson package (neither official or unofficial).

However it seems that installing rapidjson is not needed as long as the user just copies the folder include/rapidjson directly into the worktree of laminar. I.e.:

git clone https://github.com/Tencent/rapidjson
cp -r ./rapidjson/include/rapidjson ./laminar/rapidjson

(I know this is mostly a "hack", but I wanted to build it quickly.)

BTW, on OpenSUSE the following are the development dependencies needed:

capnproto
libcapnp-devel
sqlite3-devel
libboost_container1_68_0-devel

Thanks for pointing this out. Some searching led me to this but I don't know anything about openSUSE so it could be irrelevant. If there is a standardised way of submitting user packages (like the AUR for Arch Linux), it would be great to be able to share laminar with other openSUSE users.

The following link provides available packages from OpenSUSE build service for rapidjson: https://software.opensuse.org/package/rapidjson

However as seen only "source" packages are available for OpenSUSE. (At least at this moment.)

Providing OpenSUSE packages is done via https://build.opensuse.org/, which also handles the building.

(Provided I get some spare time I could try to prepare an RPM myself.)

Rapidjson is a header-only library, so the sources are all that are needed, and only for compilation.

Yes, I understand. However the "sources-only" RPM packages (i.e. *.src.rpm) are not installable, and are in fact a bundle destined for the rpmbuild tool.

Ah, ok. So if laminar sometime becomes an openSUSE rpm, all its dependencies including rapidjson would be available, right? I don't know how compatible their rpm implementations are, but I have a quick-and-dirty way to generate a rpm for centos that could be a useful starting point

In case of rapidjson it is not needed to be present for "install". (Only for "building", and this is why I contributed this "build hint" issue.)

Thus the unavailability of an rapidjson RPM is not an issue for the "user", just for the "builder".

I don't know how compatible their rpm implementations are, but I have a quick-and-dirty way to generate a rpm for centos that could be a useful starting point

I'll take a look. They should be almost compatible, most likely only dependencies are changed.

Cool, thanks :+1:

I think this issue can be closed. It is still searchable for those looking for this information.
