Bug #10350: compile error in bignum.c line 3297 with old fcc on Solaris
- Author: Naohisa G.
- Status: Closed
- Priority: Normal
- Assignee: Naohisa G.
- Category: build
- Target version:
- ruby -v: ruby 2.2.0dev (2014-10-09) [sparc64-solaris2.10]
- Backport: 2.0.0: DONTNEED, 2.1: REQUIRED
Solaris上の古い fcc (Fujitsu C compiler) 5.6 にて、以下のコンパイルエラーが発生します。
"bignum.c", line 3297: error: initialization: constant expression is
expected for variable: `nlz_bits_in_msbyte_bary'
以下のように変数の宣言と初期化を別々にしたらエラーなくビルドできました。
