编译报错

[tttttxxxxxxxx]

collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:1314: block_cache_trace_analyzer] Error 1
make[1]: Leaving directory '/home/new/rocksdb'
make: *** [Makefile:890: release] Error 2
为什么使用这个编译命令会报错呢 EXTRA_CXXFLAGS="-I/home/new/qpl/build/include" EXTRA_LDFLAGS="-L/home/new/qpl/build/lib" ROCKSDB_PLUGINS="iaa_compressor" make -j release

Hi. Thank you for reporting the issue. Could you please share more details to reproduce the error?

• Is this error observed with the latest RocksDB PR6717 and the latest IAA plugin release?
• Which QPL version?
• Which OS and compiler?

Thank you for your reply！
iaa-plugin and rocksdb ：Download it on this github method
1、：git clone https://github.com/intel/iaa-plugin-rocksdb.git plugin/iaa_compressor
2、：git clone --branch pluggable_compression https://github.com/lucagiac81/rocksdb.git
cd rocksdb
3、qpl： V1.4.0，Download it on “git clone --recursive https://github.com/intel/qpl.git ”
（qpl ： The installation was successful，Successful execution）
4、OS： debian 10 + kernel 6.6.7

I tried the following and the build completed correctly.
Ubuntu 22.04, kernel 6.2.0, gcc 11.4.0
That's the closest configuration I was able to test so far.

# Build QPL
# Source directory: qpl_source
# Install directory: qpl
git clone --recursive --branch v1.4.0 https://github.com/intel/qpl.git qpl_source
cd qpl_source
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../../qpl -DCMAKE_BUILD_TYPE=Release -DEFFICIENT_WAIT=ON .. 
cmake --build . --target install -- -j
cd ../..

# Build RocksDB with IAA plugin
git clone --branch pluggable_compression https://github.com/lucagiac81/rocksdb.git
cd rocksdb
git clone https://github.com/intel/iaa-plugin-rocksdb.git plugin/iaa_compressor
EXTRA_CXXFLAGS="-I/home/ubuntu/qpl/include" EXTRA_LDFLAGS="-L/home/ubuntu/qpl/lib" ROCKSDB_PLUGINS="iaa_compressor" make -j release
