Status: RESOLVED DUPLICATE of bug 1487810

(Thunderbird :: Build Config, defect)

Description

[bugzilla]

Attachment: tbird_change

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0
Build ID: 20180908100402

Steps to reproduce:

Compile on Debian 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux
hg pull
hg up -C
cd comm
hg pull
hg up -C
{
echo 'ac_add_options --enable-application=comm/mail'
echo 'ac_add_options --enable-debug'
echo 'mk_add_options AUTOCLOBBER=1'
} >mozconfig
nice mach build



Actual results:

Error on a file which included $repo/intl/unicharutil/util/nsUnicharUtils.h
Problem was a legal statement which did not compile.
nsCaseInsensitiveStringComparator() = default;
Changed to explicit but empty constructor made it work.
nsCaseInsensitiveStringComparator() {} // = default;
Same problem, similar file in compiling latest Firefox.


Expected results:

Compile should have succeeded.

You need a newer clang.
