Hi,
I creat my dynamic libray test.so on Linux, I can use it in my Intel Fortran code. But when I use it in Julia in ccall, I get error: undefined symbol. I have export LD_LIBRARY=$PWD. Any idea about this error? Thanks!

Check the symbol names actually exported by the library, make sure you are have it spelled right.

Which symbol is undefined? Is it in test.so or in a library that test.so depends on?

Hi John, it’s a symbol in a library that test.so depends on.

Hi, the problem is when I generated test.so, I forget the flag -L. Thanks for you help!
