Compilation issue
Opened this issue · 5 comments
I tried to install the project and I have the following error -
[100%] Linking CXX executable trans
/usr/bin/ld: /usr/local/lib/libavformat.a(http.o): undefined reference to symbol 'inflateInit2_'
//lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
MainProject/CMakeFiles/trans.dir/build.make:433: recipe for target 'MainProject/trans' failed

make[1]: *** [MainProject/CMakeFiles/trans.dir/all] Error 2

make: *** [all] Error 2
After googling for the error, I was suggested to use -lz but I couldn't figure out where to add the flags to the makefile. Can anyone point me in the right direction to fix this?
Hi pavan4 !! Sorry for the long delay. Did you manage to compile the software ? Your -lz compilation flag could probably be added to the "set(CMAKE_CXX_FLAGS ...)" cmake command in the "CMakeLists.txt" file.
Hello there! I met the same error while compiling the software
[100%] Linking CXX executable trans /usr/bin/ld: /usr/local/lib/libavformat.a(http.o): undefined reference to symbol 'inflateInit2_' //lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status MainProject/CMakeFiles/trans.dir/build.make:428: recipe for target 'MainProject/trans' failed make[2]: *** [MainProject/trans] Error 1 CMakeFiles/Makefile2:140: recipe for target 'MainProject/CMakeFiles/trans.dir/all' failed make[1]: *** [MainProject/CMakeFiles/trans.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2
I tried to add -lz into CMakeLists.txt , which is set(CMAKE_CXX_FLAGS "-lz ${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
however this didn't solve the problem. I tried add_compile_options(-lz)
too but this didn't not work too. Help appreciated if anyone has a clue about this.
@pavan4,@ Cerburrel,is the problem solved? I also meet this problem and I will appreciate if you have a clue about this and help me .

Did you find any solution? I am facing the same problem.
I am using Linux Mint to install this library and I tried 2 Linux Mint versions.
Problem:
-
Linux Mint 18.2
When I tried sudo apt-get install ffmpeg, the version 2.6 or 2.8 was installed and this version is
not enough.
Then I tried to download the ffmepg in the following website:
https://www.ffmpeg.org/The latest version is 4. something and this version is enough to compile the library.
However, a problem occured when I tried to install the library with this version 4.0 from the
website.
Solution
Linux Mint 19.1
When I tried sudo apt-get install ffmpeg, version installed 3.4.2-2 and everything worked.
Conclusion:
Do not use the lastest version from website.
use apt-get install ffmpeg. However if an old-dated ffmpeg version is installed is this case. You
need to change the Operational System.
