Hi, in our project we use a Yocto based build system (branch dunfell, Linux Kernel 5.10) for a while. At the next step, we plan to capture log messages from different sources with the help of syslog-ng (3.24.1). For some sources we will use a Python script that implements an interface to another system. Our problem is now, that we cannot build syslog-ng with a working Python support. Our build completes successfully, but the newly generated library 'libmod-python.so' seems to be broken as we get an error message when we use the following command to verify the installation. syslog-ng --module-registry | grep python Error opening plugin module; module='mod-python', error='/usr/lib/syslog-ng/libmod-python.so: undefined symbol: PyExc_ValueError' Module: mod-python Status: Unable to dlopen shared object, probably not a syslog-ng module Below you can see our current syslog recipe. syslog-ng_%.bbappend: FILESEXTRAPATHS_append := ":${THISDIR}/${PN}" DEPENDS += " python3 " # Override of default config file SRC_URI += "file://syslog-ng.conf.systemd" # Just to be sure EXTRA_OECONF_remove = "--disable-python" # Enable Python Support EXTRA_OECONF += "--enable-python --with-python=3" Can you give us hint, how to to fix this behavior? Thanks and Regards, Christian
