我正在尝试使用Linaro 6进行编译,我收到此错误,我认为这与GCC 6有关吗?我非常喜欢编译内核或编写代码,但我无法弄清楚甚至搜索类似的术语:
CC drivers/iommu/msm_iommu-v1.o
In file included from include/linux/io.h:22:0,
from drivers/iommu/msm_iommu-v1.c:20:
drivers/iommu/msm_iommu-v1.c: In function '__program_context':
drivers/iommu/msm_iommu_hw-v1.h:78:31: warning: result of '16777215 << 14' requires 39 bits to represent, but 'int' only has 32 bits [-Wshift-overflow=]
error, forbidden warning: msm_iommu_hw-v1.h:78
scripts/Makefile.build:308: recipe for target 'drivers/iommu/msm_iommu-v1.o' failed
这是我的GitHUB:
答案 0 :(得分:1)
看起来像iommu驱动程序的错误。它试图转换为int
而不是long
,int没有足够的位来完成操作。我猜测-Wno-error
未被使用,因此所有警告都被视为错误。
这个问题可以帮助您:How to compile without warnings being treated as errors?
我个人所做的是在.bashrc中更新CFLAGS
(假设您正在使用Linux)。这就是我使用的:
# Ensure C builds don't fail on warnings
export CFLAGS="-Wno-error"
export CXXFLAGS="-Wno-error"
