【问题描述】：
我们正在尝试构建 ORAN-ODU-Low 库 (https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/build_prerequisite.html)。
我们已经下载并构建了 DPDK，
#wget http://static.dpdk.org/rel/dpdk-18.08.tar.x
#tar -xf dpdk-18.08.tar.xz
#export RTE_TARGET=x86_64-native-linuxapp-icc
#export RTE_SDK=Intallation_DIR/dpdk-18.08
构建 DPDK：
#./usertools/dpdk-setup.sh
select [39] x86_64-native-linuxapp-icc
exit [62] Exit Script
'''
DPDK 构建成功。
从 odu 构建 fapi 库时，我们看到以下错误：

_mm_storeu_si128 (__m128i *__P, __m128i __B)
我们正在 CentOS 7 上构建它 - 使用的 3.10.0-1160.45.1.el7.x86_64 gcc 版本：4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
【问题讨论】：
-
那真的是 only 错误信息吗？类型为
int而不是__m128i的东西可能是由于对某物的隐式声明，例如试图使用由于旧编译器（旧系统 GCC 头文件）而未声明的函数。 -
Wrt gcc 不是 icc
-
@SindhuPitta 根据错误日志
nr5g_fapi.c第二个参数有问题。根据您上面的评论，这是针对 GCC 而不是 ICC。您能否更新有关 ICC 的错误？ -
Wrt icc 它正在请求许可证文件，我们正在关注以下链接docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/…
