[Bug 761117] New: pkg-config for fuse does not return all required libraries

IMHO the file /usr/lib(64)/pkgconfig/fuse.pc is wrong prefix=/usr exec_prefix=/ libdir=/lib64 includedir=/usr/include Name: fuse Description: Filesystem in Userspace Version: 2.9.0 Libs: -L${libdir} -lfuse Libs.private: -pthread -lrt -ldl Cflags: -I${includedir}/fuse -D_FILE_OFFSET_BITS=64 as the linker requires on the final linkage all libraries even those of Libs.private. I'm aware this is the problem with the configuration of our linker. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Archivemount uses the pthreads API explicitly, not just through libfuse and so it needs to be linked with -pthread. Other fuse filesystems build fine with the new pkgconfig file, so I don't think there's a general problem here. Closing with RESOLVED/UPSTREAM as this appears to be an archivemount bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

IMHO at least gvfs package des not use pkg-config for fuse. The configure script of archivemount (not the Maekfile nor the Makefile.in nor Makefile.am) uses pkg-config for asking the fuse package configuration but this does not work correct with our linker configuration. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Because glibc contains stub implementations for pthread features which need not to be seen first on dynamic linking time. Linking with -pthread makes sure those symbols come from libpthread. That's especially important when you dynamically open shared objects but it may also break in the face of _init code execution of other libraries you link against. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
