installing echam

[yoluo001]

When installing echam, enter the following statement "esm_master install-echam-6.3.05p2" and an error occurs after running, as shown in the following screenshot.

This is a glibc error, and affects all of albedo, might be linked to the container image currently on the login nodes.

Hi @yoluo001,

I have a provisional fix which should allow you to compile the model. I'm not sure why this hasn't popped up before, maybe you are the first person to run ECHAM-6.3.05p2 standalone on Albedo.

In your echam-6.3.05p2 source code folder, you need to modify the following file to allow the linker to find librt.so:

diff --git a/cdi/src/CMakeLists.txt b/cdi/src/CMakeLists.txt
index 2183e78..c8b80ae 100644
--- a/cdi/src/CMakeLists.txt
+++ b/cdi/src/CMakeLists.txt
@@ -23,6 +23,7 @@ target_compile_definitions(${PROJECT_NAME} PUBLIC VERSION="1.7.0" gFortran HAVE_
 target_link_libraries(${PROJECT_NAME}
    PRIVATE yaxt
    INTERFACE ${NETCDF_C_LIBRARIES} ${HDF5_C_LIBRARIES}
+   rt
 )
 if(${CMAKE_C_COMPILER_ID} STREQUAL Intel)
        # enable c99 for intel (icc defaults to c89) (gcc already defaults to a c dialect of this century)

With that addition (on little line) it compiles for me. Let me know how it works for you.

Cheers, Paul

Dear Paul,

I tried to modify it as what you said, but it seems to fail. If it is convenient for you, could you share the file you successfully ran with me? Thanks a lot.

All the best, Yongyue
