This is especially bad because an application that does -lrdkafka -llz4 will not be linked with liblz4 and will use liblz4 implementation from librdkafka instead. $ LC_ALL=C comm -12 <(/usr/lib/rpm/provided_symbols /lib64/liblz4.so.1) \ <(/usr/lib/rpm/provided_symbols /usr/lib64/librdkafka.so) LZ4F_compressBegin LZ4F_compressBound LZ4F_compressEnd LZ4F_compressFrame LZ4F_compressFrameBound LZ4F_compressUpdate LZ4F_createCompressionContext LZ4F_createDecompressionContext LZ4F_decompress LZ4F_flush LZ4F_freeCompressionContext LZ4F_freeDecompressionContext LZ4F_getErrorName LZ4F_getFrameInfo LZ4F_getVersion LZ4F_isError LZ4F_resetDecompressionContext LZ4_compress LZ4_compressBound LZ4_compressHC LZ4_compressHC2 LZ4_compressHC2_continue LZ4_compressHC2_limitedOutput LZ4_compressHC2_limitedOutput_continue LZ4_compressHC2_limitedOutput_withStateHC LZ4_compressHC2_withStateHC LZ4_compressHC_continue LZ4_compressHC_limitedOutput LZ4_compressHC_limitedOutput_continue LZ4_compressHC_limitedOutput_withStateHC LZ4_compressHC_withStateHC LZ4_compress_HC LZ4_compress_HC_continue LZ4_compress_HC_extStateHC LZ4_compress_continue LZ4_compress_default LZ4_compress_destSize LZ4_compress_fast LZ4_compress_fast_continue LZ4_compress_fast_extState LZ4_compress_limitedOutput LZ4_compress_limitedOutput_continue LZ4_compress_limitedOutput_withState LZ4_compress_withState LZ4_create LZ4_createHC LZ4_createStream LZ4_createStreamDecode LZ4_createStreamHC LZ4_decompress_fast LZ4_decompress_fast_continue LZ4_decompress_fast_usingDict LZ4_decompress_fast_withPrefix64k LZ4_decompress_safe LZ4_decompress_safe_continue LZ4_decompress_safe_partial LZ4_decompress_safe_usingDict LZ4_decompress_safe_withPrefix64k LZ4_freeHC LZ4_freeStream LZ4_freeStreamDecode LZ4_freeStreamHC LZ4_loadDict LZ4_loadDictHC LZ4_resetStream LZ4_resetStreamHC LZ4_resetStreamState LZ4_resetStreamStateHC LZ4_saveDict LZ4_saveDictHC LZ4_setStreamDecode LZ4_sizeofState LZ4_sizeofStateHC LZ4_sizeofStreamState LZ4_sizeofStreamStateHC LZ4_slideInputBuffer LZ4_slideInputBufferHC LZ4_uncompress LZ4_uncompress_unknownOutputSize LZ4_versionNumber LZ4_versionString
Это даже несколько неожиданно, потому-что по умолчанию она собирается с внешней libz. Feature options: --enable-lz4 Enable external LZ4 library support [y] --disable-lz4 Disable external LZ4 library support Буду мотреть.

Да, lz4 там больше нет. Правда, libxxhash по-прежнему экспортируется, но это уже другая история.

Аналогичная история про libxxhash: $ LC_ALL=C comm -12 \ <(/usr/lib/rpm/provided_symbols /usr/lib64/libxxhash.so.0.6.5) \ <(/usr/lib/rpm/provided_symbols /usr/lib64/librdkafka.so) XXH32 XXH32_canonicalFromHash XXH32_copyState XXH32_createState XXH32_digest XXH32_freeState XXH32_hashFromCanonical XXH32_reset XXH32_update XXH64 XXH64_canonicalFromHash XXH64_copyState XXH64_createState XXH64_digest XXH64_freeState XXH64_hashFromCanonical XXH64_reset XXH64_update XXH_versionNumber
