Bug 651692 – app-i18n/mozc-2.20.2673.102: protobuf >= 3.0.0 compile error

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Bazz 2018-03-27 11:31:03 UTC]

I've tried various versions of dev-libs/protobuf

3.0.0_beta3_p1
3.0.2
3.1.0
3.4.1
3.5.1.1

but they all produce the same compile error in mozc. I am attaching the emerge output.

Reproducible: Always

Steps to Reproduce:
1. emerge =app-i18n/mozc-2.20.2673.102
2.
3.
Actual Results:  
compile error

Expected Results:  
build success

I will be attaching `emerge --info` and the build output immediately

emerge output protoc compile error

[Comment 3 Bazz 2018-03-27 11:35:35 UTC]

Anticipation to potential questions: 

running `protoc --version` always yielded the currently installed protobuf version.

Build log shows that headers from /usr/local/include were used.
Delete these old and unnecessary headers which cause this problem.

And it is possible that there are some old libraries in /usr/local/lib, /usr/local/lib32 or /usr/local/lib64. Delete them as well.

thank you! You're a genius! :)

I had installed protobuf2 there for another project. For now, I renamed /usr/local/include/{google,google2}

At least, I could install mozc successfully now! Thank you!

Sorry for false alarm.
