Getting undefined reference to `pthread_mutex_lock' #389

Closed garkpit closed 5 years ago

garkpit commented 5 years ago

It runs for a while then spews out the error below + several hundred similar. Doesn't seem to matter which options I use. Have tried sudo ./cross_compile_ffmpeg.sh and sudo ./cross_compile_ffmpeg.sh --disable-nonfree=n --compiler-flavors=win64 --high-bitdepth=y

Error message: /home/jay/ffmpeg-windows-build-helpers/sandbox/cross_compilers/mingw-w64-x86_64/lib/gcc/x86_64-w64-mingw32/8.2.0/../../../../x86_64-w64-mingw32/bin/ld: ./.libs/libharfbuzz.a(libharfbuzz_la-hb-blob.o):/home/jay/ffmpeg-windows-build-helpers/sandbox/win64/harfbuzz_git/src/hb-mutex.hh:133: undefined reference to `pthread_mutex_lock'

On Ubuntu Desktop 19.04 fresh install

Might be my limited Linux knowledge, and this is obvious, but not to me :)

Thanks, Jay

  • Followed your instructions (after installing git)
  • Did this first after first run said to do it: sudo apt-get install subversion ragel curl texinfo g++ bison flex cvs yasm automake libtool autoconf gcc cmake git make pkg-config zlib1g-dev mercurial unzip pax nasm gperf autogen bzip2 autoconf-archive p7zip-full python3-distutils -y
  • Did sudo hoping it would help...

Thanks, Jay

Hi again. So a little PS: After getting it working on a fresh Ubuntu 19.04 I returned to my regular Linux VM which is Linux Mint 19. The warning message "Could not find the following execs (etc)" appears as if for non-Ubuntu flavours of Linux. I suggest putting the Ubuntu message instead, as it is 100% accurate on latest Linux Mint 19 (with updates applied). Great tool. Thanks again :) (pps. Am now trying to get it running on Fedora Astronomy 30 but having an issue. If I don't solve it soon I will post a fresh Issue here.)

Hi guys , I am not sure why that fix is not on the latest. I had to merge this manually to pass the build - 0fef12b

rdp commented 4 years ago
