I am using a uClibc 0.9.33.2 toolchain (latest) available from this crosstool-NG project.

I have since learned uClibc has been abandoned and forked as uClibc-ng. Upgrading to this version resolved the issue.

I'm getting what looks like the same error with nodejs 6.9.4 building on Gentoo
/var/tmp/portage/net-libs/nodejs-6.9.4/work/node-v6.9.4/out/Release/obj/gen/blink/platform/inspector_protocol/InspectorProtocol.cpp:23:5: error: 'snprintf' is not a member of 'std'
and repeats ...

Research suggests that this (and similar problems I'm having with other packages) relates to header file cleanup where some includes are no longer made indirectly.

@addaleax

@addaleax I believe this came up over at the tessel project as well /cc @rwaldron

We should likely be explicit about the headers. Would this be only for v6.x?

@MylesBorins

@MylesBorins Sorry, got a bit of an unexpected ping here … what can I do here? This doesn’t seem to be an issue on v6.x-staging, as far as I can tell … if it is, it’s quite likely that that’s a problem with the use libstdc++, not with the inspector code.

We should likely be explicit about the headers

Sorry, could you explain what you mean by that?

you we explicitly import the headers with the missing functions

yea but as far as I can tell the right headers are already included? :/
