Bug ID: 23877
Summary: `clang -print-file-name` doesn't respect LIBRARY_PATH
Product: clang
Version: 3.6
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Driver
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Unlike GCC, clang ignores LIBRARY_PATH when looking up a library via
`-print-file-name`, but it *does* consult LIBRARY_PATH when actually linking:
jim@huginn ~
$ LIBRARY_PATH=$HOME/lib gcc -print-file-name=libboost_iostreams.so
/home/jim/lib/../lib/libboost_iostreams.so
jim@huginn ~
$ LIBRARY_PATH=$HOME/lib clang-3.6 -print-file-name=libboost_iostreams.so
/usr/bin/../lib/gcc/x86_64-linux-gnu/5.1.0/../../../x86_64-linux-gnu/libboost_iostreams.so
jim@huginn ~
$ LIBRARY_PATH=$HOME/lib clang-3.6 -shared -olibfoo.so -lboost_iostreams
jim@huginn ~
$ ldd libfoo.so
linux-vdso.so.1 => (0x00007fff5c5fe000)
libboost_iostreams.so.1.55.0 =>
/home/jim/lib/libboost_iostreams.so.1.55.0 (0x00007f2d2cb3f000)
...
jim@huginn ~
$ clang-3.6 --version
Ubuntu clang version 3.6.2-svn239700-1~exp1 (branches/release_36) (based on
LLVM 3.6.2)
Target: x86_64-pc-linux-gnu
