ThinLinc's local drives is implemented using NFS, which uses Sun RPC/ONC RPC. glibc decided that this was too niche for them to continue to maintain, so modern versions of glibc has dropped this support. Users are instead expected to use a separate library, like libtirpc. Note that glibc only dropped the headers. It has so far kept the implementation, so that old binaries can continue to work. This means a modern glibc causes problems for us to build unfsd, but not to run it. We need to make sure unfsd is compatible with this brave new world.
Upstream issue for this: https://github.com/unfs3/unfs3/issues/13 And upstream fix: https://github.com/unfs3/unfs3/pull/17 The problem is that libtirpc is primarily a Linux project. It very recently got support for macOS as well, but Windows support is currently lacking. I see three paths forward: 1. Port libtirpc to Windows (probably a lot of work) 2. Revert some of the changes in unfs3 and make them conditional on platform (leaving messy legacy crud in unfs3) 3. Adapt the exiting Windows RPC library (oncrpc-ms) to follow the libtirpc API (more work than 2, less than 1, and messy code stays out of unfs3) A prototype for 2. is available here: https://github.com/unfs3/unfs3/commits/oldrpc/
Using cenbuild from MR !35 fails at building the ThinLinc Linux client: > make -C unfs3 > make[3]: Entering directory '/home/cendio/thinlinc-client-zip.9ZANF/buildarea/BUILD/thinlinc-client/unfs3' > for i in Config ; do (cd $i && make all) || exit; done > make[4]: Entering directory '/home/cendio/thinlinc-client-zip.9ZANF/buildarea/BUILD/thinlinc-client/unfs3/Config' > flex ./exports.l > bison -y -d ./exports.y > cblink gcc -Wall -O2 -g -Wall -W -I.. -I. -I.. -c -o lex.yy.o lex.yy.c > ./exports.l:9:21: fatal error: rpc/rpc.h: No such file or directory > compilation terminated. > make[4]: *** [<builtin>: lex.yy.o] Error 1 > make[4]: Leaving directory '/home/cendio/thinlinc-client-zip.9ZANF/buildarea/BUILD/thinlinc-client/unfs3/Config' > make[3]: *** [Makefile:38: subdirs] Error 2 > make[3]: Leaving directory '/home/cendio/thinlinc-client-zip.9ZANF/buildarea/BUILD/thinlinc-client/unfs3' > make[2]: *** [Makefile:511: unfs3/unfsd] Error 2 > make[2]: Leaving directory '/home/cendio/thinlinc-client-zip.9ZANF/buildarea/BUILD/thinlinc-client' > error: Bad exit status from /var/tmp/rpm-tmp.fJ2qvq (%build) > > RPM build errors: > Bad exit status from /var/tmp/rpm-tmp.fJ2qvq (%build) > make[1]: *** [Makefile:215: tlclient-linkkit-linux-x86_64.tar.gz] Error 1 > make[1]: Leaving directory '/home/cendio/thinlinc-client-zip.9ZANF/client' > make: *** [Makefile:461: client/tlclient-linkkit-linux-x86_64.tar.gz] Error 2 > PIPELINE FAILURE client-zip > cp: cannot stat '/home/cendio/thinlinc-client-zip.9ZANF/*.zip': No such file or directory This is because the UNFS we use in the ThinLinc client requires Sun RPC, which is no longer available in new glibc.
Works well after upgrade. Tested on Fedora 41, Windows 11, and macOS 15.
