help on local builds, error on tmp, seems Dockerfiles must be edited for volumes ?

[mckaygerhard]

i was trying local build as describe the readme.. installing a virtual machine and put tyhe commands, but gives me write errror, seem the dockerfiles uses some hardcoded volumes.. so those must exits on /home/node ?

the error is

  CXX(target) /home/node/node-v16.20.2/out/Release/obj.target/icuucx/deps/icu-small/source/common/ucnv_ext.o
ccache: error: Failed to create directory /home/node/.ccache/tmp: Permission denied
make[2]: *** [tools/icu/icuucx.target.mk:311: /home/node/node-v16.20.2/out/Release/obj.target/icuucx/deps/icu-

checked available space is 2.9G aftyer runs command to build, more than enought

complete commands i used was:

• apt-get install docker etc etc
• mkdir -p /home/general/Devel/unofficial-builds-home
• cd /home/general/Devel/unofficial-builds-home
• git clone https://github.com/nodejs/unofficial-builds
• cd /home/general/Devel/unofficial-builds-home/unofficial-builds/
• edit bin/_config.sh and only leaves x86 target and "header" targer
• bin/local_build.sh -r x6 -v v16.20.2

ok got it.. but the README does not point if the local build must be with root or wihtout.. it solved running as normal user..

but now i have a problem, its normal for this git env but locally build has no rules or instructions to clean locally so next different build will fails:

ccache: error: Could not find compiler "g++" in PATH
Node.js configure: Found Python 2.7.5...

did you get this warning?

Warning: UID is less than 1000, setting to 1000, output files will be owned by this UID

I'm hoping this should do the trick, would you mind checking it out and seeing? #124

I'm hoping this should do the trick, would you mind checking it out and seeing? #124

that was the first time, i just a pull request with much BETTER instructions to not so familiar users..

but found that not all recipes will build.. by example the recipe for version 20.X.Y builds fine for x86, armv6l, x64-glibc-217, musl but the version 16.X.Y of nodejs only builds for x86 recipe..

the error in those failed recipes are:

ccache: error: Could not find compiler "g++" in PATH

i previously erase all docker images and containers in system with docker prune -a cos i made the test in a clean fresh installation on a qemu VM

[rvagg]

ccache: error: Could not find compiler "g++" in PATH - if you rewind in git history you might find a version that works. This is probably just an update in the base Ubuntu/Alpine/whatever Docker image or in the names of the packages installed.

glad you've documented the expectation that they may not all work in your PR though

[mckaygerhard]

yeah thanks @rvagg noted that was in some recipes.. only few works.. by example not all v14 recipes works and gives me such errors
