9 months ago Another work-around. I also encountered this issue on Ubuntu 20.04.3 LTS (Focal Fossa) with gcc version 9.4.0.
The compilation actually breaks due to as run failure, NOT a typical undefined symbol issue which usually occurred during linking. When I check the dynamic dependence of executable as, I found that:
user@hostname:~/ppl.llm.serving/ppl-build (master)$ ldd `which as`
linux-vdso.so.1 (0x00007ffd705c6000)
libopcodes-2.34-system.so => /lib/x86_64-linux-gnu/libopcodes-2.34-system.so (0x00007f066b2ad000)
libbfd-2.34-system.so => /lib/x86_64-linux-gnu/libbfd-2.34-system.so (0x00007f066b166000)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f066b14a000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f066af22000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f066af1d000)It turns out that as depends on zlib as well.
Then, if we check the build command in grpc-build/third_party/zlib/CMakeFiles/zlibstatic.dir/build.make(at line 188 in my case), we'll find that:
cd /data/workspace/ppl.llm.serving/ppl-build/grpc-build/third_party/zlib && /usr/bin/cc $(C_DEFINES) $(C_INCLUDES) $(C_FLAGS) -MD -MT grpc-build/third_party/zlib/CMakeFiles/zlibstatic.dir/inflate.o -MF CMakeFiles/zlibstatic.dir/inflate.o.d -o CMakeFiles/zlibstatic.dir/inflate.o -c /data/workspace/ppl.llm.serving/deps/grpc/third_party/zlib/inflate.cThe cmake-generated command first change directory to .../zlib, and then run the compiler. However, this is where the compilation breaks, since .../zlib has another libz.so which is newly built and maybe INCONSISTENT. This can be checked by ls, and running ldd in .../zlib directory:
user@hostname:~/ppl.llm.serving/ppl-build/grpc-build/third_party/zlib $ ldd `which as`
linux-vdso.so.1 (0x00007ffd60389000)
libopcodes-2.34-system.so => /lib/x86_64-linux-gnu/libopcodes-2.34-system.so (0x00007ff51c340000)
libbfd-2.34-system.so => /lib/x86_64-linux-gnu/libbfd-2.34-system.so (0x00007ff51c1f9000)
libz.so.1 (0x00007ff51c1f4000) <=== here is the difference!!!!!!!!!
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff51bfcc000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007ff51bfc7000)
/lib64/ld-linux-x86-64.so.2 (0x00007ff51c55d000)Therefore, because as is launched in .../zlib directory on which another (maybe inconsistent) libz library resides, the correct system libz is not loaded.
The work-around is straightforward, just not run as in .../zlib directory (in my case I change it to upper directory).
Modify Ln188 of grpc-build/third_party/zlib/CMakeFiles/zlibstatic.dir/build.make.
#cd /data/workspace/ppl.llm.serving/ppl-build/grpc-build/third_party/zlib && /usr/bin/cc $(C_DEFINES) $(C_INCLUDES) $(C_FLAGS) -MD -MT grpc-build/third_party/zlib/CMakeFiles/zlibstatic.dir/inflate.o -MF CMakeFiles/zlibstatic.dir/inflate.o.d -o CMakeFiles/zlibstatic.dir/inflate.o -c /data/workspace/ppl.llm.serving/deps/grpc/third_party/zlib/inflate.c
