Hi,
I have been trying to build a small application that generates images using node-canvas. canvas uses the Cairo C library to do all the hard work and fortunately it exists as an RPM in CentOS 7.
However when building using mock, I was getting errors that I didn't see when building using outside of a chroot. Annoyingly the error messages weren't very helpful and say things like "This is most likely not a problem with node-gyp" but concealed the actual problem.
This is the command I was running:
mock -r epel-7-x86_64 --rebuild --no-clean SRPMS/foo.src.rpm
And this part of the output:

Within the mock environment, it is not possible to access the internet. This is a good thing because it ensures that you should get the identical output, given the same inputs and not be dependant on the outside world changing. But that didn't explain what was actually failing.
By running mock -r epel-7-x86_64 --shell, I was able to inspect the mock build environment and see what is going on. I ran node-gyp manually within the node_modules/canvas directory:
<mock-chroot> sh-4.2# /usr/bin/node /usr/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js configure --fallback-to-build --module=/builddir/build/BUILD/radiovis-slides/node_modules/canvas/build/Release/canvas-prebuilt.node --module_name=canvas-prebuilt --module_path=/builddir/build/BUILD/radiovis-slides/node_modules/canvas/build/Release --napi_version=3 --node_abi_napi=napi --napi_build_version=0 --node_napi_label=node-v48

So node-gyp is failing because it is trying to download the C headers for the current version of node-js. These same headers are provided by the nodejs-devel RPM and they are installed into /usr/include/node. I guess node-gyp doesn't know that they are there. Or doesn't know that they are the right headers for the current version of node.
I managed to work round the problem by writing a shell script to copy the headers from /usr/include/node to ~/.node-gyp/6.14.3/include/node/
There is a shell script to do this here:
https://gist.github.com/njh/189eccddaa5c05dda4608edc5301481f
- Has anyone else experienced problems with node-gyp and mocking?
- Is there a simpler solution that I have missed?
- Would it make sense to include my shell script snippet in the
%buildsection of the speculate template? - Is there any chance of an adverse affect of doing this?
