bedtools軟件安裝報錯：gzopen函數未定義（undefined reference to `gzopen64'）

在如下網站下載最新版軟件：https://github.com/arq5x/bedtools2/releases/tag/v2.26.0

https://github.com/arq5x/bedtools2/releases/download/v2.26.0/bedtools-2.26.0.tar.gz

wget https://github.com/arq5x/bedtools2/releases/download/v2.26.0/bedtools-2.26.0.tar.gz

tar xzf bedtools-2.26.0.tar.gz

cd bedtools2

vim Makefile，將第28行修改爲：prefix = /ifs4/BC_COM_P5/F15FTSECKF0984/PEOahnD/PEOahnD/hlb/bin/bedtools-2.26/

make

報錯：

- Building main bedtools binary.

obj/gzstream.o: In function `gzstreambuf::open(char const*, int)':

gzstream.C:(.text+0x2a2): undefined reference to `gzopen64'

collect2: ld 返回 1

make: *** [all] 錯誤 1

搜索系統中庫文件：

locate libz.so | less

輸出如下：

/lib64/libz.so.1

/lib64/libz.so.1.2.3

/root/zlib-1.2.8/libz.so

/root/zlib-1.2.8/libz.so.1

/root/zlib-1.2.8/libz.so.1.2.8

/usr/lib64/libz.so

/usr/local/lib/libz.so

/usr/local/lib/libz.so.1

/usr/local/lib/libz.so.1.2.8

分別查詢上述.so文件中的函數地址，如果都找不到，則需安裝最新版本的libz

objdump -T /lib64/libz.so.1 | grep gzopen64

objdump -T /lib64/libz.so.1.2.3 | grep gzopen64

objdump -T /root/zlib-1.2.8/libz.so | grep gzopen64

objdump -T /root/zlib-1.2.8/libz.so.1 | grep gzopen64

objdump -T /root/zlib-1.2.8/libz.so.1.2.8 | grep gzopen64

objdump -T /usr/lib64/libz.so | grep gzopen64

objdump -T /usr/local/lib/libz.so | grep gzopen64

objdump -T /usr/local/lib/libz.so.1.2.8 | grep gzopen64

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

export LDFLAGS="-L/usr/local/lib"

make
