【问题描述】：

我正在尝试将程序与自定义 GLIBC 安装链接。我尝试了以下选项，但得到了同样的错误

objs/ngx_modules.o \
-Wl,--emit-relocs -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so -ldl -Wl,-rpath-link,/opt/glibc-2.23-install/lib -lcrypt -lpcre -lz \
-Wl,-E
/usr/bin/ld: objs/src/core/ngx_shmtx.o: undefined reference to symbol 'sem_post@@GLIBC_2.2.5'
/opt/glibc-2.23-install/lib/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

和

objs/ngx_modules.o \
-Wl,--emit-relocs -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so -ldl -L/opt/glibc-2.23-install/lib -lcrypt -lpcre -lz \
-Wl,-E
/usr/bin/ld: objs/src/core/ngx_shmtx.o: undefined reference to symbol 'sem_post@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
objs/Makefile:226: recipe for target 'objs/nginx' failed

和

objs/ngx_modules.o \
-Wl,--emit-relocs -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so -ldl -L/opt/glibc-2.23-install/lib/libpthread.so -lcrypt -lpcre -lz \
-Wl,-E
/usr/bin/ld: objs/src/core/ngx_shmtx.o: undefined reference to symbol 'sem_post@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
objs/Makefile:226: recipe for target 'objs/nginx' failed

那还有什么办法吗？

【问题讨论】：

标签： gcc glibc

【解决方案1】：

-Wl,--emit-relocs -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so -ldl -L/opt/glibc-2.23-install/lib/libpthread.so -lcrypt -lpcre -lz \ -Wl,-E

激烈的活动不能代替理解。你想要的命令：

gcc objs/ngx_modules.o  \
  -Wl,-E -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so \
  -L/opt/glibc-2.23-install/lib \
  -lcrypt -lpcre -lz -lpthread
