Sharp: Building sharp on centos (without root) and getting vips working

[vrghost242]

Good morning

Having a bit of an issue with updating sharp on the server I use for hosting my webpage.
I use a company called webfaction (not that important but may help someone) on a centos machine (centos-release-6-7.el6.centos.12.3.x86_64) without vips.

So I installed libvips manually using configure --prefix=/home/me/libs
It is installed and seems OK
Added LDPATH and LD_LIBRARY_PATH to bashrc

export LD_LIBRARY_PATH="/home/tentogive/libs/lib"
export LDFLAGS="-L$HOME/libs/lib $LDFLAGS"

Seems to work, but when I run npm install sharp I get an error message about vips not working (I think that is what its trying to tell me) and something about manual build, but could not find any more specific build. Here is the full message:

npm install sharp

Not certain if I am barking up the wrong tree, but how can I set, force or check if npm can see the library, or does anyone know if it uses LDPATH or LD_LIBRARY_PATH?

Hello, the quickest solution here is probably to ask Webfaction for Centos 7 rather than 6 as their docs suggest it's available.

[vrghost242]

Does centos 7 come with sharp built, or why would centos7 help me?

[vrghost242]

OK, one step forward (if someone has the same issue)

If you need to tell npm where to find a package you need to use PKG_CONFIG_PATH, and it must point to where the .pc files are. In my case:
export PKG_CONFIG_PATH=/home/tentogive/lib/pkgconfig

However I found that I also need a newer gcc, so will have to update to Centos 7 anyway:)

"why would centos7 help me"

The pre-compiled libvips binary that sharp downloads and uses will "just work" with Centos 7 (as the underlying version of glibc it contains is >= 2.13).

@vrghost242 Were you able to get everything working with Centos 7?

[vrghost242]

Yes, sorry, took a while to migrate everything, but yes, builds perfectly on centos 7
