Hi, I have written an EC to install some Python codes as a tarball and successfully installed it. However, when the user tries to use it, he gets the following error:
Importing the numpy c-extensions failed. ... Original error was: libgfortran.so.4: cannot open shared object file: No such file or directory I used the foss-2019b toolchain, which uses GGC 8.3.0, which has the following: $ ll libgfortran.so* lrwxrwxrwx 1 build staff 20 Sep 30 2019 libgfortran.so -> libgfortran.so.5.0.0 lrwxrwxrwx 1 build staff 20 Sep 30 2019 libgfortran.so.5 -> libgfortran.so.5.0.0 -rwxr-xr-x 1 build staff 10799408 Sep 30 2019 libgfortran.so.5.0.0 Version 4 of the library is available from GCC 7.3.0: $ ll libgfortran.so* lrwxrwxrwx 1 build staff 20 Jan 17 2019 libgfortran.so -> libgfortran.so.4.0.0 lrwxrwxrwx 1 build staff 20 Jan 17 2019 libgfortran.so.4 -> libgfortran.so.4.0.0 -rwxr-xr-x 1 build staff 7291944 Jan 17 2019 libgfortran.so.4.0.0 I can obviously rebuild the software with the appropriate toolchain, but I'd like to know what's going on. Why does numpy care about the version of libgfortran? Isn't the function of the link 'libgfortran.so' precisely to avoid this kind of breakage?
