这里有一个Ubuntu的新手,这让我很困惑。
目前正在尝试使用make构建OpenImageIO,遵循此处列出的步骤:https://sites.google.com/site/openimageio/checking-out-and-building-openimageio
据我所知,我已安装了所有依赖项,但尝试运行make会出现以下错误:
platform=linux64, hw=x86_64
OPENIMAGEIO_SITE = shanesimmsart-pc
dist_dir = dist/linux64
INSTALLDIR = /home/shanesimmsart/oiio

有没有人知道我可能做错了什么/可能会丢失?
答案 0 :(得分:1)
您正在使用的软件包默认启用了-Werror
标志,这会强制编译器将所有警告视为错误。这对于向用户发送代码总是一个坏主意,因为用户将拥有各种不同的编译器和编译器版本,因此用户将获得与开发人员不同的警告。当开发人员构建代码时,他们绝对应该使用-Werror
。当开发人员向用户发送代码时,他们绝对应该不启用-Werror
。
无论如何,看看Git中的代码,看来如果你这样做:
make STOP_ON_WARNING=no
它会停用-Werror
。
