Question

我正在编译我的应用程序，它包含二进制文件和一些动态库。我的makefile使用

LDFLAGS=-Wl,-rpath='$$ORIGIN/../lib',-rpath=/opt/suse/lib64,--disable-new-dtags

对于没有asan的正常构建，这样可以在运行时首先在../lib中搜索所有库（直接链接和动态加载）。

当我使用带有-fsanitize = address的asan用于CXXFLAGS和LDFLAGS时，ld不再使用rpath来搜索动态加载的（dlopen）库。

echo $LD_LIBRARY_PATH
:/EDI_TOOLS/ORACLE/client:/home1/conic/Trafo/program/UmsetzerV19

strace输出：

open("tls/x86_64/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("tls/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("x86_64/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/EDI_TOOLS/ORACLE/client/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/home1/conic/Trafo/program/UmsetzerV19/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib64/gcc/x86_64-suse-linux/5/Consumer_EndTransaction.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/etc/ld.so.cache", O_RDONLY)      = 4
fstat(4, {st_mode=S_IFREG|0644, st_size=83482, ...}) = 0

objdump -x给出了这个输出（更多，但rpath设置正确）。可以正确找到NEEDED中的所有库。

我正在使用SLES 11

g++-5 (SUSE Linux) 5.3.1 20160301 [gcc-5-branch revision 233849]
GNU ld (GNU Binutils; SUSE Linux Enterprise 11) 2.25.0
ld.so-1.7.0

我错过了什么吗？

似乎围绕dlopen()的ASAN包装器改变了它的行为。看起来像以下错误：https://bugzilla.redhat.com/show_bug.cgi?id=1449604

使用asan运行程序不使用rpath
