Description Slava Semushin 2008-05-19 20:11:24 MSD

I have following stuff:

boost-devel-1.34.1-alt1
gcc4.1-c++-4.1.2-alt2

When I compile simple code with -Wshadow flag I got many warnings:

Code with trivial example will me attached.

Example of code.

Comment 2 Slava Semushin 2008-05-19 20:16:06 MSD

P.S. May be it was fixed in boost-1.35 version, I don't known because doesn't
have it for testing... :-(

Comment 3 Damir Shayhutdinov 2008-05-19 20:17:26 MSD

Слава, поговори пожалуйста на эту тему с апстримом, я не настолько силен в С++,
и уж тем более не силен в том надругательстве над С++, которое постоянно делают
авторы boost.

Comment 4 Slava Semushin 2008-05-19 20:22:19 MSD

Я так и думал, поэтому и написал на английском, чтобы потом можно было сослаться
на баг :) Я просто думаю, вдруг это в 1.35 исправлено? Я что-то не смог найти у
них в системне контроя версий возможность посмотреть какие изменения
производились с файлом и когда. Ладно. Напишу им в рассылку, пожалуй..

Comment 5 algor 2008-05-20 09:39:17 MSD

php-coder: как напишешь в рассылку, прицепи сюда линк, плз. чисто поржать.

http://www.nabble.com/boost%3A%3Aspirit-example-program-produce-many-warnings-when-compiled-with--Wshadow-option-to17324157.html

Можешь ржать: патч "Applied in Boost SVN trunk."

Comment 8 Slava Semushin 2008-10-12 22:35:39 MSD

Created attachment 2992 [details]
Патч для boost 1.36.0

Странно, похоже, что в буст не полностью патч приняли, потому что варнинги частично всё равно остались. Обновил патч.

Comment 9 Ivan A. Melnikov 2008-10-13 14:11:22 MSD

Нашёл вот:

http://svn.boost.org/trac/boost/ticket/2304

Приложеный туда патч исправляет ещё несколько подобных потенциальных проблем. Стоит на него посмотреть, а заодно и спросить у апстрима их мнение по этому поводу.

2 php-coder@ : спросите? а то я на spirit-general не подписан...

Comment 10 Ivan A. Melnikov 2008-10-17 22:31:36 MSD

В сизифе уже лежит boost-1:1.36.0-alt3, где это исправлено. Багу можно закрывать.

Comment 11 Ivan A. Melnikov 2008-10-24 20:49:04 MSD

Обновил boost до 1.36.0-alt3 из Cизифа, проверил, работает.
