[kozyilmaz]

@lindanlee ~Are you using El Capitan like the previous report by any chance?~

[lindanlee]

@kozyilmaz, I'm using High Sierra.

[kozyilmaz]

Can you please send me the outputs of these two commands below $ cat zcash/zcash_master/config.log |grep enable-werror $ cat zcash/zcash_master/config.log |grep Werror

Can you try with master again? I guess a simple git pull will do. Following commits (https://github.com/kozyilmaz/zcash-apple/commit/00260cf22b342dbf6de0f9fd9cbebd1e88b95ae7 and https://github.com/kozyilmaz/zcash-apple/commit/b972042e6f9572f6434617fc3501707959cedda1) will fix the build for now but I'll look why -Werror is not supported anymore.

[lindanlee]

@kozyilmaz, thanks for the help.

the output for $ cat zcash/zcash_master/config.log |grep enable-werror is :

As you instructed, I ran the following commands afterwards in the zcash-apple directory: git pull source environment PRINT_DEBUG=y make all

I get the following error:

[kozyilmaz]

oh please execute this command in zcash directory $ cd zcash $ rm -rf .cloned .configured .patched zcash-master

then build all

[lindanlee]

I executed: $ cd zcash $ rm -rf .cloned .configured .patched zcash-master

And tried to make again by: source environment PRINT_DEBUG=y make all

It's been building for a while! I'm hopeful... I'll let you know soon.

[kozyilmaz]

Yes it probably will but it was not the correct fix :) I'll commit another patch to fix it for good

Anyway your built binaries will be fine even with current master so no worries

[lindanlee]

Sad! It was building for 25+ minutes or so, and then failed. :(

Do you know what could cause this?

[kozyilmaz]

Hmm @lindanlee I'll fixed the previous issue properly and pushed it to master.

The last one however is really weird. Do you have macports or brew installed (although very unlikely to be the source of such an issue)?

I'll appreciate a clean build (I mean even clone from scratch) with logs (only Zcash will do). Sorry for the trouble and thanks for your patience.

[lindanlee]

@kozyilmaz, thank you so much for the continued assistance.

I do have macports and brew installed, if that makes a difference. I'll try the process from the top following the instructions from https://github.com/kozyilmaz/zcash-apple in a new directory.

[kozyilmaz]

Unfortunately macports and brew cause too much trouble, I'll try to limit the interference but sometimes it is impossible. If both are present can you also post the results of the following commands too?

$ gcc -v
$ g++ -v
$ clang -v
$ which autoconf
$ which automake
$ which libtool
$ autoconf --version
$ automake --version

Thanks again!

[lindanlee]

I made another directory, and ran the following commands:

git clone https://github.com/kozyilmaz/zcash-apple.git
cd zcash-apple
source environment
PRINT_DEBUG=y make all

It's still building--I'll let you know if it succeeds.

In another tab, in the zcash-apple directory I am building in,, I ran the commands you suggested:

Those last two seem concerning. but maybe I shouldn't have run them while things were still building; maybe they haven't been downloaded yet. :o

[kozyilmaz]

No worries, it is fine. If you would have run source environment in zcash-apple directory first, autoconf/automake commands will return correctly but again, it is just fine.

[lindanlee]

@kozyilmaz, I updated the results above by running the command after running source environment.

The build failed again:

make[1]: *** [build] Error 1

I pulled after the build and confirmed that it was up to date.

Hmm, do you have additional ideas of what I should do? Or do you have an idea of what could be causing this?

[kozyilmaz]

can you please paste (or copy to a text file and attach) the complete Zcash build log?

[lindanlee]

It's so long that it was truncated in my terminal, but here's the last bit of it.

terminal-build-output.txt

[kozyilmaz]

@lindanlee There are a lot of errors present (see log below) but I know for certain that it is not possible to build Zcash with earlier clang versions like yours. Latest clang that came with Xcode 9 fixed the template related issues and after this commit https://github.com/kozyilmaz/zcash-apple/commit/3613b572f75fa82394cff4962559ff5df2f0d920 on December 1st it was possible to build natively with clang

So I recommend you to upgrade Xcode/Command Line Tools to latest first. I can confirm that this version below works. Is it possible for you to update Xcode?

This is strange.

[kozyilmaz]

Strange indeed, do you have an Xcode installation? Checked mine and Xcode version is "Version 9.2 (9C40b)"

[lindanlee]

I thought I downloaded all the updates in the command line, but when I check the app on my computer, it's quite old, 8.2.1. I'll try to update the app and try again.

[lindanlee]

I've updated xcode; I'll try building later tonight. If it doesn't work, I'll try on another computer (I just got a new macbook, so it'll be a couple days until I set it up/try again).

Thanks for so much of your help!

[lindanlee]

I'll update you on if that works, when I do it. :)

[kozyilmaz]

Sure, please do. Sorry for the trouble!

[lindanlee]

I tried it after updating xcode, I got it to work on my old computer. :) Thanks for all the help!
