CESM移植最后一步报错relocation truncated to fit

一大碗年糕

昨天在移植CESM1.2.2到另一个平台，build case到最后一步的时候报错，cesm.bldlog显示relocation truncated to fit: R_X86_64_PC32的错误信息，即已经成功完成了前面的 MCT、PIO、GPTL、组件库（atm/lnd/ice/ocn 等）编译，最终在链接阶段（link stage）失败。

1. libifcoremt.a(for_diags_intel.o): In function `for__this_image_number_or_zero':

问题原因（参考GPT回答）：这是一个链接器地址空间截断错误，即：目标文件和静态库之间的地址寻址范围不兼容。
解决办法：
1.在config_compilers.xml文件中的LDFLAGS添加"-shared-intel"某些机器默认静态链接 Intel runtime (libifcoremt.a)，可以改成动态链接以避免 relocation 溢出：
2.替换pio和netcdf版本
之前好像有次安装的时候碰到类似的这个问题，通过替换netcdf和pio版本解决了，可以参考https://bb.cgd.ucar.edu/cesm/thr ... ntel-compiler.3389/
