Hi, I have the same issue with Bullseye. I build Docker images for various platforms, with Alpine Edge or Ubuntu 22.04 bases, those build succeed.But if fails with the same error with a Bullseye base, and on my own machine which runs Bullseye too. I use the source file from guacamole.apache.org/releases/1.5.4/ for all builds. Something with time.h versions? They are a bit different between Bullseye, Bookworm and Jammy, but the references for the functions in question are there and signatures look the same, and I am not familiar enough with linux/c headers to dig more. Cheers Antoine

Could you try doing the following in the 1.5.4 source directory:make distcleanautoreconf -fi and then re-run configure and make? I just pulled the source code from the web site and built on my EL8 system without any issues. If you're still having trouble, please provide some more detail on the environment you're building in. -Nick
