<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal>I’m new to llvm and klee. Now I’m trying to build up
coreutil with klee.<o:p></o:p></p>
<p class=MsoNormal>Following the steps online (<a
href="http://klee.llvm.org/TestingCoreutils.html">http://klee.llvm.org/TestingCoreutils.html</a>),
I went to step 3 and stuck.<o:p></o:p></p>
<pre>When I try to run:<o:p></o:p></pre><pre> <b>klee --libc=uclibc --posix-runtime ./cat.bc –version<o:p></o:p></b></pre><pre>Error occurred like:<o:p></o:p></pre><pre>klee: error: Cannot find linker input '/lib/libc.a'<o:p></o:p></pre><pre>klee: ModuleUtil.cpp:42: llvm::Module* klee::linkWithLibrary(llvm::Module*, const std::string&): Assertion `0 && "linking in library failed!"' failed.<o:p></o:p></pre><pre>0 klee 0x0000000000e3b21f<o:p></o:p></pre><pre>1 klee 0x0000000000e3bcda<o:p></o:p></pre><pre>2 libpthread.so.0 0x00000036d000dd40<o:p></o:p></pre><pre>3 libc.so.6 0x00000036cf430015 gsignal + 53<o:p></o:p></pre><pre>4 libc.so.6 0x00000036cf431980 abort + 272<o:p></o:p></pre><pre>5 libc.so.6 0x00000036cf429726 __assert_fail + 246<o:p></o:p></pre><pre>6 klee 0x000000000058a541 klee::linkWithLibrary(llvm::Module*, std::string const&) + 193<o:p></o:p></pre><pre>7 klee 0x0000000000523fbe<o:p></o:p></pre><pre>8 klee 0x000000000052bafc main + 7052<o:p></o:p></pre><pre>9 libc.so.6 0x00000036cf41d8a4 __libc_start_main + 244<o:p></o:p></pre><pre>10 klee 0x0000000000521fd9<o:p></o:p></pre><pre>Aborted<o:p></o:p></pre><pre><o:p> </o:p></pre><pre>I wonder why it looks for libc.a under /lib, and I’m not sure how to direct it to the correct location.<o:p></o:p></pre><pre>In fact, I’m not sure which libc it should point to. I try to modify the makefile under obj-llvm, changing ‘libdir’ to /usr/lib and /my/path/to/uclibc/lib, but neither works.<o:p></o:p></pre><pre><span

<p class=MsoNormal>Later I rebuild and try to let LD_LIBRARY_PATH point to
uclibc/lib, the error remains the same.<o:p></o:p></p>
<p class=MsoNormal>One thing I should mention is, some error happened during
the “make check”:<o:p></o:p></p>
