pthread_rwlock_wrlock does not initialize?

joachimmetz commented 5 years ago

Per readme the thread safety (RW locking) is still WIP, I'll have a look if I can reproduce it. What operating system/platform are you using to build the source?

zhanleewo commented 5 years ago

I using ubuntu desktop 18.04 64bit. acutally single thread mode is ok for my propose.

joachimmetz commented 2 years ago

This is likely related to ./configure --enable-static-executables. Closing this issue in favor of https://github.com/libyal/libyal/issues/81

For now add --enable-multi-threading-support=no
