[Gretl-devel] pca command dependency

Hi all, I've compiled gretl using latest git version on an otherwise clean ubuntu 19.10 system. Gretl works fine for most stuff I am doing there. However, the "pca" command fails, and I guess there is some package dependency which I am not fulfilling and which is not required for compiling gretl. <output> /usr/local/lib/gretl-gtk2/pca.so: cannot open shared object file: No such file or directory pca_from_cmatrix: get_function_address failed Failed to load plugin: /usr/local/lib/gretl-gtk2/pca.so Couldn't load plugin function *** error in function pca_encode, line 27 called by function test_pca_encode </output> Anybody does have some hint? Thank you, Artur
